Detailed Description
The technical scheme of the invention is further described below by the specific embodiments with reference to the accompanying drawings.
Example 1
As shown in fig. 1 to fig. 4, in order to avoid the security problem that the centralized authentication mode is easy to tamper with information, the known authentication process is ensured to be safer, more reliable, more efficient and more convenient, and furthermore, the distributed authentication method for intellectual property rights and interests based on blockchain provided in the embodiment comprises the following steps:
S10: uploading intellectual property rights information to an exclusive blockchain, wherein the exclusive blockchain is an intellectual property rights authentication chain;
S20: authenticating the uploaded intellectual property right information by using an intelligent contract, and judging whether an authentication result of the intellectual property right information is valid or not;
S30: if the authentication result is valid, outputting the authentication result, and storing the authentication result to the distributed account book of the exclusive blockchain by calling the intelligent contract when the authentication result indicates that the intellectual property rights and interests information passes authentication;
s40: if the authentication result is invalid, reminding the user of authentication failure and ending the task.
The intellectual property owner uploads the own intellectual property right information to the blockchain through a system interface, and the uploaded intellectual property right information can comprise various types of intellectual property right information such as copyright, patent, trademark and the like, wherein the intellectual property right information comprises a right person name, a right person identity certificate, a right person contact way, a right name, a right scope, a right term and the like. Through the process, the rights and interests information of the intellectual property owners is recorded on the distributed account book of the blockchain, so that the non-tamper property and security of the information are ensured. Here authentication will be divided into two parts, meaning passing authentication to varying degrees: firstly, the authenticity of the rights and interests information can be checked through the normal signature disclosed by the office party and can be decrypted and applied when the user party issues the rights and interests information; the second property of the rights information can be verified to have the right to use by using the authorization mode of the user. Wherein, the office party represents authority management mechanisms such as an intellectual property management office, a central institution and the like.
In order to ensure that the identity of the uploader is the intellectual property owner, the intellectual property rights information needs to be authenticated to ensure the safe reliability of the intellectual property management. Further, smart contracts are used to ensure authenticity and trustworthiness of the authentication to prevent malicious attacks and tampering of intellectual property beneficial information. Automated intellectual property transfer is achieved through blockchain intelligence contracts. The intelligent contract can be automatically executed under the condition that the preset condition is met, manual intervention is not needed, and the transaction efficiency and the credibility are improved. The method can combine various authentication modes such as data hash authentication, signature authentication, rights and interests authentication, password authentication, biological feature authentication, verification code authentication and the like, so that an uploading user is ensured to be the owner of the intellectual property or a user authorized by the owner of the intellectual property, and the safety and reliability of the information authentication of the rights and interests of the intellectual property are ensured.
Preferably, the authenticating the uploaded intellectual property right information by using the intelligent contract, and judging whether the authentication result of the intellectual property right information is valid, includes:
Carrying out hash operation processing on the uploaded intellectual property rights and interests information to obtain data fingerprint information, sequentially carrying out signature verification and rights and interests verification on the data fingerprint information, and judging whether an authentication result of the intellectual property rights and interests information is effective or not;
If the data fingerprint information sequentially performs signature verification and rights verification, and the signature verification and the rights verification pass, the authenticity and the attribute of the intellectual property rights information pass, the authentication result is valid, otherwise, the authentication result is invalid and the task is ended.
And carrying out hash processing on the uploaded intellectual property rights and interests information to generate a unique data fingerprint. The hash algorithm has the main functions of ensuring the consistency and the non-falsification of the data and reducing the cost of data storage and transmission. Wherein, the hash algorithm can adopt SHA-256, MD5 and the like. The authenticity and effectiveness of the intellectual property rights and interests information can be ensured through hash operation verification.
The data fingerprint information is carried by the office party when issuing and signed by the private key of the office party, and is stored in a chain after being encrypted by using the encryption private key submitted when the party to which the rights belong applies, and is stored icfs by a fragmentation technology, so that the data security is ensured and the data privacy is also ensured. The public key provided by the office party to the public is an important certificate for verifying the authenticity of the information, and all people can download or obtain the public information to the official network. The public key can be verified by the public party, the authenticity of the rights and interests can be verified by decrypting the information from the party, the verification can be released, the fact that the party is actually the party can be verified, and the metadata can be indexed to the metadata through the complete distributed storage link address to download and reconstruct to obtain the actual text.
Preferably, the hash operation processing for the uploaded intellectual property right information includes:
carrying out hash operation processing on the uploaded intellectual property right information, generating a digest hash value of the data fingerprint information of the current intellectual property right, and judging whether the digest hash value of the data fingerprint information exists in a digest Ha Xiku stored in the intellectual property right block chain;
If so, indicating that the current intellectual property right information is registered in the intellectual property right blockchain, and reminding an uploading person to upload information again;
if not, writing the data fingerprint information of the current intellectual property into the intellectual property right block chain, and recording uploading time and authentication results.
When the intellectual property right information authentication is carried out, firstly, the hash value of the intellectual property right information to be authenticated is calculated, specifically, the hash value of text information such as the intellectual property copyright information, abstract content and the like is calculated, wherein, the hash value calculation can be carried out by adopting an MD5 algorithm,
The method comprises the steps of carrying out MD5 calculation on byte streams of intellectual property right information data to be authenticated to obtain 64-bit abstract ciphertext, inquiring whether the hash value of the intellectual property right information to be authenticated has a matched hash value in an intellectual property right block chain, if so, indicating that the intellectual property right information to be authenticated exists in the intellectual property right block chain, not allowing the intellectual property to be repeatedly registered, and if not, writing data fingerprints into the block chain, and recording uploading time and authentication results. The authentication results are written onto the blockchain for subsequent querying and verification. Through the process, the uniqueness of the intellectual property rights and interests information is ensured, and the repeated authentication registration problem is avoided.
It should be noted that, the hash value is obtained by calculating the content of the file of the intellectual property rights and interests information, the hash value can change along with the change of the file content, the hash value can be stored as the name of the file, the repeated registration of the intellectual property rights and interests information can be avoided to a certain extent through the hash value, the consistency and the non-falsifiability of the data are ensured, and the cost of data storage and transmission can be reduced. Each right hash value is unique, so that the repeatability is ensured, and the real file can be verified on the premise of not unlocking the whole capacity of the real file, thereby obtaining the authentication result of the authenticity and the attribution.
In order to ensure that the uploaded intellectual property rights and interests information is real and effective intellectual property rights information and ensure the accuracy and reliability of the information, further, hash operation processing is carried out on the copyrighted information in the uploaded intellectual property rights and interests information, wherein the copyrighted information comprises an intellectual property name, an application number or a registration number, an applicant or a right man, abstract hash of the copyrighted information of the current intellectual property rights is extracted, and whether the abstract hash of the copyrighted information is matched with abstract hash in abstract Ha Xiku of the copyrighted information of the intellectual property rights registered by the national intellectual property bureau is judged;
if the matching is successful, indicating that the current intellectual property rights and interests information is real and effective information;
If the matching fails, the current intellectual property rights and interests information is indicated to be invalid information, and an uploading person is reminded to upload information again.
Preferably, the signature verification includes:
Matching the signature information of the uploading person with the signature information in the signature information library stored in the intellectual property rights block chain, and judging whether the signature of the uploaded intellectual property rights information is matched or not;
If the signatures are matched, carrying out the rights and interests verification;
and if the signatures are not matched, re-verifying the intellectual property rights and interests information.
In the process of block chain authentication, signature verification is required to be carried out on the uploaded rights and interests information so as to ensure that the identity of an uploading person is true and reliable. The digital signature algorithm is a cryptography-based encryption technology, and can encrypt and decrypt information and verify the authenticity and integrity of the information. Common digital signature algorithms are RSA, DSA, ECDSA, etc.
In a specific embodiment, the intelligent contract verifies the data fingerprint to determine whether the uploaded intellectual property rights information is valid. The signature verification is used for judging whether the signatures of the uploading rights and interests information are matched or not so as to identify whether the identity of the uploading person is legal and effective or not, and the identity of the uploading person is ensured to be true and reliable. The identity of the uploading person is the intellectual property owner which is identified and authenticated by the system and registers the signature information or the user which is authorized by the intellectual property owner to sign the information, and the identity is identified as legal and effective identity.
Further, if the signature verification is not matched, calling a knowledge verification intellectual property rights and interests information base to verify whether the intellectual property rights and interests are transferred or not;
if the intellectual property rights and interests are transferred, determining whether the transferred rights and interests are matched with the signature;
If the transferred rights and the signature are matched, the signature information base is updated, otherwise, the task is ended.
In the event of transfer, the transferor re-encrypts the information for storage in pieces, and embodies the asset transfer operation in the equity contracts, and the distributed storage is also transferred. Due to the uniqueness of the hash value, the rights and interests stored on the chain can only be independently used at each moment, and the decryption can only be carried out by using the public and private keys of the real owners, and the original owners do not have the decryption use capability after transfer.
Preferably, the rights verification includes:
according to the uploaded intellectual property rights information, matching the identity information of the uploading person with the right person information of the current intellectual property rights information, and verifying whether the uploading person has rights for authentication;
if the information is successfully matched, the uploading person is indicated to have authentication authority, wherein if the identity of the uploading person is the intellectual property owner or the user authorized by the intellectual property owner, the uploading person is indicated to have authentication authority;
if the information matching fails, reminding an uploading person to check the identity information again, and ending the task.
By judging that the identity information of the uploading user is matched with the right person information, when the identity of the uploading user is the intellectual property owner or the user authorized by the intellectual property owner, the uploading user is indicated to have authentication rights, so that the property of the intellectual property rights and interests information is verified, and the right of use can be verified by using a user authorization mode.
Preferably, each intellectual property owner is provided with a distributed identity DID account on the intellectual property rights block chain;
The distributed identity DID account comprises a super public key pair, a sub public key pair, a super private key pair and a sub private key pair, and is used for encryption, decryption and signature verification;
The distributed identity DID account hosts an intellectual property management bureau through an uploading sub public key and is used for issuing a signature;
The super public key pair and the super private key pair are issued by a local Ca, generated based on an sm2 algorithm, and subjected to local escrow, and the super private key pair provides unique downloading;
The sub public key pair and the sub private key pair are both generated by the derivation of the user according to the super private key pair and uploaded to the local side trusteeship, and signature verification and decryption are carried out when the sub public key pair and the sub private key pair are used;
and creating an intellectual property non-homogeneous verification model token for mapping the entity intellectual property on a blockchain network, so that the entity intellectual property content is stored on the intellectual property right blockchain by adopting distributed storage.
The adoption of a distributed identity DID account corresponds to opening an account at a bank and then placing rights and interests into a safe. Specifically, the user applies for opening an account on the platform, real-name authentication is carried out by the office party, a corresponding DID is generated after the real-name authentication is passed, the DID comprises a unique account on a chain, and the DID account comprises a super public key pair and a sub public key pair. The super public-private key pair is issued by the office Ca, generated based on the sm2 algorithm, and the public key pair is subjected to office hosting, and the private key pair provides a unique download. The sub-private key pair and the public-private key pair are generated by the user according to the super private key pair in a derived mode and uploaded to the local side host, the generation algorithm is not limited, the user determines the sub-private key pair and the public-private key pair by using the corresponding algorithm in use, signature verification and decryption are achieved, all the public-private key pairs are managed through local side management and on-chain mounting operation, and the super private key pair and the sub-private key pair are used for encryption, decryption and signature verification.
It should be noted that, in order to ensure that the ownership and the usage rights of the intellectual property owners are safer and more reliable, the reliability is higher, so that the product or service has leading uniqueness without actually disclosing the technical details of the product or service to the clients or the public. The present invention should therefore focus on utilizing the binding of blockchain distributed identities to intellectual property.
Each intellectual property owner is temporarily set as a company, each company has a unique identity in the intellectual property blockchain network, which is called a distributed identity DID account temporarily, the distributed identity DID account owner has a super public and private key pair on hand, and a plurality of fixed sub public and private key pairs are arranged below the super public and private key pair for encryption, decryption and signature verification.
The general logic is that each piece of applied intellectual property is issued by the intellectual property management bureau, the DID account owner is hosted by the intellectual property management bureau through uploading a sub public key for signature issuing, and meanwhile, an intellectual property non-homogeneous general certificate model token is created for mapping the entity intellectual property on a blockchain network, and the content of the entity intellectual property is stored by using distributed storage and bound with the token one to one.
The DID account owner may disclose the token in any of his products or descriptions and issue a child private key and a super private key to the verifying party to be checked, and verifying the signature of the intellectual property authority with the child private key may achieve verification of the authenticity of the asset. The knowledge right can be proved to be really owned by the DID account owner by using the super private key.
The system can also be used for realizing the scene of intellectual property transfer or authorized use. In particular, the transfer process is similar to token transfer transaction, and the token ownership is transferred to the name of the new DID account owner, and the transfer process is also applicable to the logic of the super public and private key pair and the sub public and private key pair. Except that the electronic content in the distributed storage needs to be re-encrypted with the new master's private key and saved.
In an authorized use scenario, authorized use requires the use of a specific smart contract, similar to signature logic that is valid for a period of time. The method is characterized in that an intelligent contract is created by using a super private key of a DID account owner, which is equivalent to an independent Ca visa mechanism-belonging to the DID account owner, ca can perform secondary issuing operation on all assets under the name of the Ca, but the intelligent contract has certain timeliness (set by the DID account owner), namely, a certificate issued by Ca has a specific public-private key pair and becomes an authorized public-private key pair temporarily, the intelligent contract is paid to an authorizer, the authorizer holds the authorized public-private key pair and can check signature of a specific sub private key signature by a function similar to that of the super private key, the encryption of the sub public key is decrypted, the unique difference is that the special public key is attached with two invalidation conditions, the effective period of the contract is noted, the special public-private key is automatically invalidated, and the DID account owner can realize immediate invalidation by invoking a breach of faith method of the intelligent contract through the super private key.
Registering the intellectual property right information successfully authenticated in the form of digital assets on the intellectual property right blockchain for carrying out intellectual property transaction and intellectual property assignment tasks; and under the condition that the preset condition is met, the intelligent contract automatically executes the intellectual property transaction and the intellectual property transfer task. In the intellectual property transfer process, payment and settlement issues are involved. Blockchain technology can provide a secure, fast, low cost payment and settlement mechanism while avoiding the cumbersome and costly procedures of traditional financial institutions.
Through the process, the ownership and the use right of the intellectual property owner are ensured to be safer and more reliable, and the reliability is higher.
In order to prevent fraud and disputes in intellectual property transfer, further, the intellectual property right blockchain stores and records uploading information, uploading time, authentication results, signature records, verification records, authorization records and transaction information of the intellectual property right to form a blockchain tracing mechanism;
The blockchain tracing mechanism is used for tracing the history record process of creation, modification and transfer of intellectual property rights.
The intellectual property right blockchain is managed by authority management mechanisms such as a central mechanism, each creation, modification and transfer dynamic state of the intellectual property right is actually recorded in the blockchain, the attribution right or the use right branch of each stage is clearly recorded, the attribution right or the use right branch comprises time, signature records, verification records and the like, and finally a blockchain tracing mechanism is formed. By using the blockchain tracing mechanism, fraud and disputes in intellectual property transfer can be prevented, the history record and the transaction process of the intellectual property transfer can be tracked, the transparency and the credibility of the transaction can be ensured, and the potential risk is avoided.
According to the intellectual property right authentication method, the intellectual property right information, the authentication result, the authorization record, the transaction flow direction and other information are recorded through the blockchain, and the rights and interests of an intellectual property owner and a purchaser are protected through the blockchain. And the problems that the loss of an intellectual property owner is caused by the fault of the management center are avoided by combining the cryptography related technology in the processes of intellectual property authentication, intellectual property registration, intellectual property purchase and intellectual property traceability. The authority management mechanism ensures the legal security of the identity of the verifier through multiple Bool verification (namely invalid verification) such as intellectual property rights and interests information verification, signature verification, rights and interests verification and the like.
Preferably, the intelligent contract adopts a multi-factor authentication mechanism to authenticate the uploaded intellectual property rights information;
The multi-factor authentication mechanism includes at least one authentication mechanism of password authentication, biometric authentication, and verification code authentication.
It should be noted that, the authentication mechanism is used as a way to operate in a convenient application scenario, in fact, the unique text content such as a password, a biological feature, etc. is hashed, and is used as a mapping of the above-mentioned super public-private key pair, and is recorded into the intelligent contract, that is, the super public-private key pair in the intelligent contract can be used by using the authentication methods, so as to transfer, use or authorize the intellectual property rights under the super public-private key pair. But the user must be ensured to keep the password and the biological characteristics safely or a secondary authentication mode can be used. Encryption technology based on cryptography ensures the privacy and security of information by using cryptography technology. The multi-factor authentication method is adopted, and the security and reliability of authentication are ensured by adopting a plurality of authentication methods including password authentication, biological feature authentication, verification code authentication, secondary confirmation and the like. The intellectual property owner uploads own rights and interests information to the blockchain, the system uses the intelligent contract to authenticate, the authentication result is recorded on the blockchain, and the security and reliability of authentication are ensured through a multi-factor authentication mechanism.
Preferably, the intellectual property rights information includes at least one of trademark rights information, patent rights information, copyright rights information, integrated circuit layout design information, and geographical mark information. The application is applicable to rights and interests information authentication of various intellectual property rights and has wider application scenes.
In addition to the above technical solution, the present invention may also adopt various embodiments. For example, intellectual property rights information may be stored on a plurality of blockchain nodes to improve fault tolerance and robustness of the system. In addition, the authorization and licensing process of intellectual property rights can be automatically managed through intelligent contracts to improve the efficiency and operability of the system.
In other embodiments, the invention can also utilize consensus algorithm to create a reputation system model based on data consensus nodes, confirm the state of the account book through the interaction of multiple nodes, combine the credit weighting evaluation of the nodes, and make a decision on the actual condition of the account book record, so that all nodes agree on the authenticity of the intellectual property rights information and the decisions of the attribute;
the account book is used for recording matters generated by the intellectual property rights authentication chain, and the matters comprise proposal phase matters, voting phase matters and acceptance phase matters, and specifically comprises the following steps:
Proposal phase: one or more nodes provide a decision or suggestion to other nodes, make a decision on the authenticity and the attribution of the intellectual property rights and interests information, the reputation system model simulates human society, an event generator can be an intellectual property owner or a user authorized by the intellectual property owner, such as a creator and a modifier newly created by the intellectual property data content or a transferee or a transferor of rights transfer, the simulated event generator broadcasts outwards, the nodes which can be directly contacted are recording nodes, and the actual situation of recording is determined by combining the credit weighting evaluation of the nodes, namely, the authenticity and the attribution of the intellectual property rights and interests information are determined.
Voting: after the node receives the proposal, it needs to vote on the proposal, and usually only if the vote reaches a certain proportion is accepted. The account book state refers to the real state of the blockchain world describing the intellectual property rights and interests authentication chain, the account book generally refers to a notepad, records the occurrence of the intellectual property rights and interests authentication chain, namely when an occurrence happens, the occurrence tells other nodes that the nodes reach consensus to perform unified recording, if people hold anti-opinion, voting is needed, the account book state can be recorded exceeding 2/3, if no agreement or inconsistent response is achieved, an additional node is added to perform voting until a plurality of agreements are achieved.
And (3) a receiving stage: when a proposal is accepted by enough nodes, it can be considered as a consensus result.
In the present invention, a social principle-based consensus algorithm is created, which may be referred to as "social proving consensus" (Social Proof Consensus, SPC). The core of this algorithm is to determine acknowledge a debt the present state through multi-node interactions, while punishing inconsistent respondents. The following is a preliminary, stylized description of this algorithm:
Initializing: each node has an initial reputation score (Reputation Score, RS) indicating its trustworthiness, and certain social network relationships between nodes indicating their familiarity or communication efficiency. All nodes on the network can participate in the record, and the nodes which are recorded in advance actually are a plurality of nodes described by the consensus algorithm.
The query process comprises the following steps: when account balance needs to be verified, a certain number of adjacent nodes (for example 3) are selected to initiate a query, and the query message contains account ID and requested property information. All the evidence-passing economy of the blockchain network refers to token, and the token can be used as a valuable balance record or simply used as an index of more contents.
Response mechanism: the node which receives the inquiry checks the local account book and returns the property information of the account. If a node does not have relevant information, it will forward the query to other nodes it knows. The property information of the invention refers to specific content indexed by the token, such as actual files, content, abstracts and the like of actual intellectual property rights and interests information.
Consistency test: if at least 2/3 of the responses (in the first 3 nodes) are identical, then the consensus result is accepted. If the responses are inconsistent, an additional node is added to vote until a majority agreement is reached.
Reputation system:
an initial reputation value (R i (0) =r 0) is set,
Updating the reputation value after each round of answers based on the correctness of the answer
R_i(t+1)＝R_i(t)+DeltaR_{text(pos)}；
If the answer is wrong or dishonest
R_i(t+1)＝R_i(t)+DeltaR_{text(neg)}；
Wherein t represents a time step;
[ DeltaR _ { text (pos) } ] and [ DeltaR _ { text (neg) } ] represent the positive and negative reputation amounts,
Delta = Σ { theoretical Delta value (i) ×number of options (i) ×corresponding rights per option };
In the subsequent queries, the voting weight of node (i) is
Nodes that answer errors, whose RS is subtracted, such as- Δrs, where Δrs is a predetermined deduction value.
Nodes that do not provide information may not be withheld by their RSs if they subsequently provide the correct information, but may be considered unreliable if there are multiple times of no information.
Specifically, when the patent inventor who needs the query technology A1 is company a, it is possible to go to the blockchain network query, broadcast the query, then someone knows and someone else does not know the answer, and the person who does not know can go to ask his friends until the person who has resolved the situation is transferred to answer.
In the process of collecting answers, a person says that company A is an invention of company B, A is borrowed or infringed only, then the result needs to be identified through 2/3 majority voting, then inconsistent I consider as dishonest node, the credit model is deduction processing, and the next time the node answers again needs to be weighted. It should be noted that if you initially ask node a next to you but it answers unknown, then go to ask friend a2 next to her, a2 does not know and then ask a3 again, then a3 gives the wrong answer, then the credit model process will be a3 instead of a. a simply communicates information, similar to the principle of link forwarding where 6 phones can reach the united states president.
Weighted voting: on the next query, the voting weight of the node with the lower reputation score is reduced, for example, w=rs/MaxRS, which is the full reputation score.
Dynamic adjustment: the social network can be dynamically adjusted according to the reputation and interaction effect of the nodes, and frequently-erroneous nodes can be gradually dredged by other nodes.
Final decision: when a majority agreement is reached, the results are recorded into the blockchain and broadcast to the full network.
Randomly selecting (K) nodes (adjacent nodes) from the node set for inquiring,
(K) Satisfy the following requirements
Let (V) be the set of all responses, if there is one financial value (V),
So that
And is also provided with
Then (V) is considered to be the property that has been identified,
If the consensus is not reached, then (K+m) < frac { K } until the consensus is reached,
Wherein (m) is a newly added node.
In the above process, the node set is a node that can be directly contacted after broadcasting, but not all nodes of the present network. The response is an action taken on the event, for example, if the response is a newly added broadcast, it refers to the case that the node set records the event, and if the response is a query, it is the result returned by the query. Property information of the invention refers to specific content indexed by a token, such as actual files, content, abstracts, etc. of actual intellectual property rights information. By coordinating the communication and state conversion between the nodes, the agreement between the nodes is ensured, thereby ensuring the authenticity of the intellectual property rights and interests information and the consistency of decisions made by the attribution of the authentication system.
