Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Example one
Referring to fig. 1, a flowchart of specific steps of an unlocking verification method according to an embodiment of the present invention is shown.
Step 101, obtaining order information, wherein the order information comprises an order validity period and a target door lock.
The embodiment of the invention is applied to a door lock server, and the server can respectively generate the real-time password and the activation code according to whether the target door lock is on line.
A typical application scenario in the embodiment of the present invention is door lock management of hotel rooms, where a hotel management system generates order information according to check-in information of a user, and sends the order information to a door lock server.
Wherein, the order validity period can be the cut-off time of the user in the room.
The target door lock can be a door lock corresponding to a room where the user enters, and the door lock has a unique identifier. In practical applications, the identifier is set at the time of factory shipment, or determined according to hotel and room numbers.
And 102, acquiring a door lock key corresponding to the target door lock.
The door lock key is a hardware identifier of the door lock. Each door lock corresponds to a unique door lock key.
It can be understood that the door lock key may be carried in the order information, may be obtained from a database of the door lock server, or may be obtained from other specified servers.
The network state refers to whether the target door lock can be communicated with a door lock server through a network or not, and if the target door lock cannot be communicated with the door lock server through the network, the target door lock is in an offline state; if so, the target door lock is in an online state.
It can be understood that, in an online state, the target door lock can directly receive information, such as a real-time password, sent by the door lock server, so that the door lock can verify the password input by the user through the password; in an offline state, the target door lock cannot receive the information sent by the door lock server, and therefore the user identity needs to be verified in other ways.
In practical application, the door lock server can send detection information to the target door lock, and if the feedback information is not received within a certain time period, the target door lock is determined to be in an off-line state; and if the feedback information is received in the time period, determining that the target door lock is in an online state.
And 104, under the condition that the target door lock is in an off-line state, generating an activation code according to the order validity period and the door lock secret key, and sending the activation code to a third-party system, wherein the activation code is used for verifying the target door lock and unlocking the target door lock after the verification is passed.
The activation code can be generated by splicing the order validity period and the door lock secret key according to a certain rule and encrypting. It is understood that the embodiment of the present invention does not limit the specific generation method thereof.
According to the embodiment of the invention, aiming at the scene that the verification password cannot be received in the off-line state, the generated activation code is sent to the third-party system, so that the user can input the activation code into the target door lock after acquiring the activation code, and the target door lock can carry out user identity verification only according to the activation code.
Third party systems, including but not limited to hotel management systems, or room management systems or other designated systems, may be networked and in communication with the door lock server.
It can be appreciated that the activation code can be sent to the user's cell phone by a worker who is currently notifying the user of the activation code in the hotel management system when the user checks in the hotel.
In practical application, the order information may further include a user mobile phone number, so that the door lock server may also directly send the generated activation code to the user mobile phone.
In summary, an embodiment of the present invention provides an unlocking verification method, where the method includes: acquiring order information, wherein the order information comprises an order validity period and a target door lock; acquiring a door lock key corresponding to the target door lock; determining whether the network state of the target door lock is in an offline state; and under the condition that the target door lock is in an offline state, generating an activation code according to the order validity period and the door lock key, and sending the activation code to a third-party system, wherein the activation code is used for verifying the target door lock and unlocking the target door lock after the verification is passed. Can be when producing new order of living in, and the lock is in the off-line, inform the user through the third party and use the activation code to unblank, can avoid the potential safety hazard that the use of former password exists after the house user changes.
Example two
Referring to fig. 2, it shows a flowchart of specific steps of an unlocking verification method according to a second embodiment of the present invention.
Step 201, obtaining order information, wherein the order information comprises an order validity period and a target door lock.
This step can refer to the detailed description of step 101, and is not described herein again.
And step 202, acquiring a door lock key corresponding to the target door lock.
This step can refer to the detailed description of step 102, and is not described herein again.
This step can refer to the detailed description of step 103, which is not repeated herein.
And 204, under the condition that the target door lock is in an offline state, generating a first validity period ciphertext according to the order validity period and the door lock key.
Specifically, the validity period of the order and the door lock key may be spliced into one object, and then encrypted to obtain a first validity period ciphertext.
Optionally, in another embodiment of the present invention, the step 204 includes sub-steps 2041 to 2042:
substep 2041, calculating a difference between the order validity period and a preset reference time to obtain a first relative validity period.
The time for recording can be set according to the actual application scenario, and is not limited in the embodiments of the present invention.
In practical applications, the relative validity period can be expressed in minutes and seconds.
And a substep 2042, after the first relative validity period and the door lock key are spliced, encrypting by adopting a symmetric algorithm to obtain a first validity period ciphertext.
Specifically, the first relative validity period may be spliced behind the door lock key, and the door lock key may also be spliced behind the first relative validity period. The splicing sequence is not limited by the embodiment of the invention.
The symmetric algorithm is a traditional encryption algorithm, and an encryption key and a decryption key can be mutually derived. In most cases, the encryption key and the decryption key are the same.
It can be understood that the algorithm for generating the first check code is different from the algorithm for generating the first validity period ciphertext, and may be embodied as a different encryption algorithm.
Optionally, in another embodiment of the present invention, the step 205 includes sub-steps 2051 to 2052:
and a substep 2051, after the order validity period and the door lock key are spliced, encrypting by using a digest algorithm to obtain a first password.
Specifically, the order validity period may be spliced behind the door lock key, and the door lock key may also be spliced behind the order validity period. The splicing sequence is not limited by the embodiment of the invention.
The digest algorithm is characterized in that an encryption key is not needed in the encryption process, encrypted data cannot be decrypted, and the same ciphertext can be obtained only by inputting the same plaintext data and performing the same digest algorithm. The digest algorithm does not have the problems of management and distribution of encryption keys, and is suitable for a distributed network.
In an embodiment of the present invention, the digest algorithm may select MD 5.
And a substep 2052, encrypting the first password by using a digest algorithm to obtain a first check code.
It can be seen that the first check code is subjected to the two-time digest algorithm, and the security is higher.
And step 206, splicing the first validity period ciphertext and the first check code into an activation code, and sending the activation code to a third-party system, wherein the activation code is used for verifying the target door lock and unlocking the target door lock after the verification is passed.
Specifically, the first validity period ciphertext may be spliced after the first check code, or the first check code may be spliced after the first validity period ciphertext. The splicing sequence is not limited by the embodiment of the invention.
It can be seen that the activation code has two parts of contents, and when the identity is verified, the two parts of contents can be decrypted to obtain two results of the same object, and the two results are compared to check the activation code.
In summary, an embodiment of the present invention provides an unlocking verification method, where the method includes: acquiring order information, wherein the order information comprises an order validity period and a target door lock; acquiring a door lock key corresponding to the target door lock; determining whether the network state of the target door lock is in an offline state; and under the condition that the target door lock is in an offline state, generating an activation code according to the order validity period and the door lock key, and sending the activation code to a third-party system, wherein the activation code is used for verifying the target door lock and unlocking the target door lock after the verification is passed. Can be when producing new order of living in, and the lock is in the off-line, inform the user through the third party and use the activation code to unblank, can avoid the potential safety hazard that the use of former password exists after the house user changes.
EXAMPLE III
Referring to fig. 3, it shows a flowchart of specific steps of an unlocking verification method provided by the third embodiment of the present invention.
The embodiment of the invention is applied to the intelligent door lock.
The door lock is used for verifying the identity verification code input by the user and unlocking after verification is passed or unlocking is not performed when verification is not passed.
The door lock server is used for managing the door lock, sending a real-time password to the door lock and a third-party system, sending an activation code to the third-party system and the like.
The authentication code input by the user includes but is not limited to: an activation code, an offline password, and a real-time password.
The authentication code is obtained from the third party system when the user first enters the room. For example, for hotel check-in, the hotel staff sends the activation code obtained by the hotel management system to the mobile terminal of the user, or notifies the user of the activation code.
In practical applications, in order to distinguish between various types of authentication codes, a user first inputs a designated symbol before inputting identity information.
Step 302, determining whether a real-time password with an appointed validity period is obtained, wherein the validity period includes the current time.
When the door lock is in an online state, the door lock server can send a real-time password to the door lock through a network and appoint a validity period. When the real-time password exists and the current time is within the validity period, determining to acquire the real-time password with the specified validity period; and when the real-time password does not exist or the current time is not within the validity period, determining that the real-time password with the specified validity period is not acquired.
And step 303, determining whether the identity verification code input by the user is the activation code or not under the condition that the real-time password with the appointed validity period is not acquired.
In the embodiment of the invention, the online acquired real-time password is preferentially adopted for identity authentication. And when the real-time password is not acquired, performing primary identity authentication by using the activation code acquired offline.
Specifically, it may be determined according to the length or a special symbol input in advance. For example, when a user first inputs a "JHM" symbol, the code is determined to be an activation code; or the length of the authentication code input by the user is 10, and the activation code is determined.
And 304, under the condition that the identity verification code is an activation code, verifying the activation code, and unlocking after the verification is passed.
It can be understood that if the activation code input by the user is the activation code generated by the door lock server, the activation code is verified by adopting a verification algorithm corresponding to the generation algorithm; and if the activation code input by the user is not the activation code generated by the door lock server, adopting a verification algorithm corresponding to the generation algorithm for the activation code to obtain that the activation code is not verified.
In summary, an embodiment of the present invention provides an unlocking verification method, where the method includes: receiving an identity verification code input by a user; judging whether a real-time password with an appointed validity period is acquired, wherein the validity period comprises the current moment; determining whether the identity verification code input by the user is an activation code or not under the condition that the real-time password with the appointed validity period is not acquired; and under the condition that the identity verification code is an activation code, verifying the activation code, and unlocking after the verification is passed. The new order of putting into the house can be generated, and the door lock is in an off-line state, the lock is unlocked by using the updated activation code, so that the potential safety hazard caused by the use of the original password after the house user changes can be avoided.
Example four
Referring to fig. 4, it shows a flowchart of specific steps of an unlocking verification method provided in the fourth embodiment of the present invention.
This step can refer to the detailed description of step 301, and is not described herein again.
Step 402, determining whether a real-time password with an appointed validity period is obtained, wherein the validity period comprises the current moment.
This step can refer to the detailed description of step 302, and is not described herein again.
And step 403, determining whether the identity verification code input by the user is the activation code or not under the condition that the real-time password with the appointed validity period is not acquired.
This step can refer to the detailed description of step 303, which is not described herein.
In step 404, in the case that the authentication code is the activation code, a second check code and a third check code are extracted from the activation code.
Specifically, the second check code and the third check code are obtained by respectively decrypting different segments in the activation code.
It is understood that the algorithm for extracting the second check code and the third check code corresponds to the generation rule of the activation code. And under the condition that the activation code is generated by the door lock server, the first check code, the second check code and the third check code are the same.
Optionally, in another embodiment of the present invention, the step 404 includes sub-steps 4041 to 4043:
substep 4041, obtaining data of a first segment preset in the activate code to obtain a second parity code.
The activation code is formed by splicing a check code and a validity period ciphertext, so that the check code can be extracted from the activation code.
In practical application, the validity period ciphertext is m bits, the check code is n bits, and if the validity period ciphertext is located in front of the check code, the first segment is m +1 to m + n bits. For example, if m is 7 and n is 3, the activate code is 2101933786, the first segment is 8-10 bits: the second parity code is 786.
Substep 4042, obtaining data of a second segment preset in the activation code to obtain a second validity period ciphertext.
For example, the activation code 2101933786 indicates that the second segment is 1 to 7, i.e., the second validity period ciphertext is 2101933.
It can be understood that the concatenation order of the validity period ciphertext and the check code may be changed, and the lengths of the first segment and the second segment may also be set according to an actual application scenario, which is not limited in the embodiment of the present invention.
Substep 4043, generating a third check code according to the second validity period ciphertext and a preset door lock key.
Specifically, the second validity period ciphertext is decrypted through the door lock key, and the specific algorithm is the reciprocal of the algorithm for generating the first validity period ciphertext.
Optionally, in another embodiment of the present invention, the sub-step 4043 includes sub-steps 40431 through 40434:
and a substep 40431, decrypting the second validity period ciphertext by using a symmetric algorithm according to a preset door lock key to obtain a second relative validity period.
It is understood that this step is the reciprocal operation of the substep 2042 of the second embodiment.
Wherein the second relative validity period corresponds to the first relative validity period and the second validity period ciphertext corresponds to the first validity period ciphertext. In addition, the door lock key is the same.
Substep 40432, calculating the sum of the second relative validity period and the preset reference time to obtain an absolute validity period.
It is understood that this step is the reciprocal operation of the substep 2041 of the second embodiment.
Wherein the base time is the same and the absolute validity period corresponds to the order validity period.
Substep 40433, after the absolute validity period and the door lock key are spliced, encrypting by using a digest algorithm to obtain a second password.
This step uses the same summarization algorithm as sub-step 2051.
The second password corresponds to the first password.
Sub-step 40434, encrypt the second password by using digest algorithm to obtain the third check code.
This step uses the same summarization algorithm as sub-step 2052.
The third check code corresponds to the first check code.
It can be seen that sub-steps 40433 to 40434 are the same algorithm as sub-steps 2051 to 2052, namely: and during decryption, the primary check code (namely the third check code) is regenerated by adopting the absolute validity period obtained by decryption from the activation code. It is understood that the second check code of the first segment in the activation code corresponds to the first check code generated by the doorlock server.
And 405, if the second check code is consistent with the third check code, the activation code passes verification, and the lock is unlocked after the verification passes.
It can be understood that the second check code is consistent with the third check code, and the activation code input by the representative user is the activation code generated by the lock server for the target lock, so that the verification is passed.
And step 406, if the second check code is not consistent with the third check code, the activation code verification is not passed.
It can be understood that the second check code is consistent with the third check code, and the activation code input by the representative user is not the activation code generated by the lock server for the target lock, so that the verification is not passed.
In the embodiment of the invention, when the user enters the room for the first time, if the activation code passes the verification, the second password and the absolute validity period extracted from the activation code are written into the door lock, so that the user can unlock through the second password subsequently.
And 408, verifying the password according to the second password and the absolute validity period under the condition that the identity verification code is the password, and unlocking after the verification is passed.
In practical application, a device for recording time exists in the door lock, so that the current time can be acquired, and whether the current time is in the valid period or not is judged.
