Detailed Description
The invention will be described in detail hereinafter with reference to the accompanying drawings in conjunction with embodiments. It should be noted that the embodiments and features of the embodiments in the present application may be combined with each other without conflict.
It should be noted that the terms "first," "second," and the like in the description and claims of the present invention and in the drawings described above are used for distinguishing between similar elements and not necessarily for describing a particular sequential or chronological order.
To further illustrate the block chain based collaborative office method, apparatus, and system in the embodiments of the present invention, the following describes an application scenario of the block chain based collaborative office method, apparatus, and system in the embodiments of the present invention:
the block chain is a chain data structure formed by connecting and combining data blocks according to a time sequence, and the data blocks are guaranteed to be not falsifiable and not forged in a cryptographic mode. Each chunk in the chain of chunks is linked to the immediately preceding chunk in the chain of chunks by including a cryptographic hash of the preceding chunk. Each tile also includes a timestamp, a cryptographic hash of the tile, and one or more transactions. Transactions that have been verified by nodes of the blockchain network are hashed and form a Merkle tree. In a Merkle tree, data at leaf nodes is hashed and, for each branch of the Merkle tree, all hash values of the branch are concatenated at the root of the branch. The above process is performed for the Merkle tree up to the root node of the entire Merkle tree. The root node of the Merkle tree stores a hash value representing all the data in the Merkle tree. When a hash value claims to be a transaction stored in the Merkle tree, a quick verification can be performed by determining whether the hash value is consistent with the structure of the Merkle tree.
A blockchain network is a network of computing nodes used to manage, update and maintain one or more blockchain structures. In an embodiment of the present invention, the blockchain network may include a public blockchain network, a private blockchain network, or a federation blockchain network.
In a public blockchain network, the consensus process is controlled by nodes of the consensus network. For example, there may be thousands of entity co-processes in a public blockchain network, each entity operating at least one node in the public blockchain network. Thus, a public blockchain network may be considered a public network of participating entities. In some examples, most entities (nodes) must sign each chunk in sequence and add the signed chunk to the blockchain of the blockchain network. An example of a public blockchain network may include a particular peer-to-peer payment network.
Public blockchain networks support public transactions. Public transactions are shared among all nodes within a public blockchain network and are stored in a global blockchain. A global blockchain refers to a blockchain that is replicated across all nodes. To achieve consensus, a consensus protocol is implemented within a public blockchain network. Examples of consensus protocols include, but are not limited to: proof Of Work (Proof Of Work, POW), Proof Of rights (Proof Of stamp, POS), and Proof Of Authority (Proof Of Authority, POA).
A private blockchain network is provided for a particular entity. The read-write authority of each node in the private blockchain network is strictly controlled. Thus, private blockchain networks, also commonly referred to as licensed networks, limit the level of network participation and the participation of an object in the network. In private blockchain networks, various types of access control mechanisms may be used.
A federation blockchain network is private between participating entities. In a federated blockchain network, the consensus process is controlled by an authorizing node. For example, a federation consisting of several entities may operate a federated blockchain network, with each entity operating at least one node in the federated blockchain network. Thus, a federated blockchain network can be considered a private network of participating entities. In some examples, each participating entity must sign each chunk in order and add the chunk to the chain of chunks. In an example, each tile may be signed by a subset of participating entities and added to the chain of tiles.
In the embodiment of the present invention, the implementation of the embodiment of the present invention may be described in detail with reference to a federation blockchain network, and in an example, the method, the apparatus, and the system for block chain-based collaborative office in the embodiment of the present invention may be implemented by a federation blockchain network based on a fabric architecture. It should be noted that the embodiments of the present invention may also be implemented in any suitable blockchain network.
Fig. 1 is a system architecture diagram of a block chain-based collaborative office method according to an embodiment of the present invention, and as shown in fig. 1, a block chain network 102 may be a block chain network of a public chain, a private chain, or a federation chain. Blockchain network 102 may have deployed therein computing device 104, computing device 106, computing device 108, computing device 110, computing device 112, and network 114. In an example, the Network 114 can include a Local Area Network (LAN), Wide Area Network (WAN), the internet, or a combination thereof, and can be connected to websites, user devices (e.g., computing devices), and backend systems, and the computing devices 104, 106, 108, 110, 112 can access the Network 114 via wired and/or wireless communications.
The computing devices 104, 106, 108, 110, 112 described above form blockchain nodes in the blockchain network 102, and the computing devices 104, 106, 108, 110, 112 may run any suitable computing system that enables them to function as blockchain nodes in the blockchain network 102. In an example, the computing device may include, but is not limited to, a server, a desktop computer, a laptop computer, a tablet computing device, and a smartphone. In the embodiment of the present invention, the computing device 104, the computing device 106, the computing device 108, the computing device 110, and the computing device 112 may correspond to different business departments or business individuals, in an example, the computing device 104, the computing device 106, the computing device 108, the computing device 110, and the computing device 112 may respectively correspond to office computing devices adopted by the business department 01, the business department 02, the business department 03, the business department 04, and the business department 05, and office systems such as an electronic official document system, a supervision system, an attendance recording system, a conference management system, an affair management system, and a financial management system may be operated in the computing devices, so that any computing device operating a preset office system may constitute a block chain node in the embodiment of the present invention.

It should be noted that, in the embodiment of the present invention, a pair of public and private keys for encryption and decryption may be granted to each business department or business personnel, and thus, each block chain node is correspondingly configured with a pair of public and private keys. When the business department or business personnel uploads the business data, the public key or the private key can be used for encrypting the business data to be uploaded. In one example, a public key corresponding to the business department can be called, and field-level encryption is performed on data through the public key; in another example, a private key corresponding to the business department may be retrieved, and the business data is digitally signed by the private key. In the above optional embodiment, the encryption processing performed on the service data may ensure the validity of the service data publishing main body, so as to re-form the transaction of the block chain and submit the transaction to the public ledger, thereby making the service data recorded on the chain safe and reliable.
It should be noted that, in an example, the above encryption or digital signature manner may be implemented based on the secret SM2 asymmetric encryption algorithm, or implemented by another encryption algorithm, which is not limited by the embodiment of the present invention.

the standard data format is used for indicating a preset data standard among a plurality of service nodes.
In an optional embodiment, the intelligent contract at least comprises a standard business format; in the step S104, converting the first service information into the second service information according to a preset intelligent contract, further includes:
and converting the service data according to the standard service format, and generating second service information according to the converted service data and the second data format.
The standard service format is used for indicating a service standard preset by a plurality of service nodes.
It should be noted that, in the optional embodiment, the data standard and the service standard may be solidified through the standard data format and the standard service format in the intelligent contract, so that different service data uploaded by the same service department or service data between different service departments may be subjected to the unification processing according to the data standard and the service standard. Therefore, communication channels which can mutually trust and mutually identify can be established among different business departments, so that business linkage among the departments is realized, transparent rules are executed, business processes are simplified, office informatization construction mode optimization is promoted, data use and business calling of each department are accelerated while data of each department are integrated, and efficient operation of group office is realized.
And S106, writing the second service information into the block chain by the first block chain node.
It should be noted that, the first block link point writes the second service information into the block chain, that is, the second service information is written into the public ledger, so that each block link point in the block chain maintains the second service information together.
In an optional embodiment, after the step S106 writes the second service information into the block chain, the method further includes:
obtaining an authorization record of the second service information, and writing the authorization record into the block chain; wherein the authorization record is used to indicate a record of authorization to access the second service information.
Therefore, when another blockchain node in the blockchain network requests to access the second service information in the blockchain, whether the second blockchain node authorizes to access the second service information or not can be confirmed according to the authorization record. The foregoing is illustrated by an alternative embodiment
Acquiring an access request; the access request is used for indicating a second block chain link point to request access to second service information in the block chain;
inquiring an authorization record of the second service information according to the intelligent contract;
and in the case that the second block link point meets the authorization record, allowing the second block link point to access the second service information.
Through the technical scheme described in the above optional embodiment, access authorization to related service information can be recorded through the blockchain. It should be noted that the second block link node matches the authorization record, i.e., the authorization record includes the second block link node, and in an example, the second block link node matches the unauthorized record, i.e., the second block link node is not included in the authorization record. The second block link point may be any one of the plurality of block link nodes other than the first block link point.
Through the cooperative office method based on the block chain in the embodiment of the invention, each business department can issue the business data to the block chain through the block chain link point according to the preset standard of the intelligent contract. Therefore, the embodiment of the invention can solve the problem that the overall planning of the co-construction and sharing of office data resources among all business departments in the related technology cannot be realized through the distributed characteristic of the block chain, so that all block chain nodes in the block chain can participate in the storage and verification of the business data uploaded by the business departments, and further all the block chain nodes can jointly maintain a common account book, thereby achieving the effect of ensuring that all the business departments can timely and accurately realize the sharing of the business data and further realizing the cooperative office.
Meanwhile, the embodiment of the invention can further ensure the traceability of the transaction through the characteristic of public and private key encryption, and ensure that the service data cannot be repudiated and destroyed, thereby ensuring that the privacy of a service department or a service individual is not leaked. In addition, in the implementation process of the block chain-based collaborative office method in the embodiment of the invention, each business department does not need to completely overturn the existing workflow and data storage mode, and only needs to share part of necessary business data, so that collaborative office among different departments can be implemented through the block chain.
On the basis, the block chain-based cooperative office method in the embodiment of the invention reconstructs a data sharing mechanism and a business process reconstruction among business departments. For the cooperation of cross-department cooperative business processes and mechanisms in a way of satisfying formal exchange in the related technology or meeting self blocking business index assessment and pyramid of each department, the cooperative office realized in the embodiment of the invention can be realized based on the all-round and common management of each business department.
