It should be noted that: like reference numbers and letters refer to like items in the following figures, and thus, once an item is defined in one figure, further discussion thereof is not required in subsequent figures.
As previously mentioned, during the course of a user's interaction with an enterprise, the enterprise often needs to initiate authentication of the user's identity. The enterprise needs to authenticate the user through an authentication department, for example, the authentication department may be a public security department, a communication operator, a bank, an education department, etc. This requires the user to provide private information to the enterprise, such as identification numbers, cell phone numbers, bank cards, academic calendars, and the like.
The inventors of the present disclosure have recognized that private information provided by a user to an enterprise is protected solely by the integrity of the enterprise. This kind of authentication mode has very big privacy disclosure risk, and the user can't know even that individual privacy is revealed by who.
Based on the above recognition, the inventors of the present disclosure found that blockchain nodes can be deployed at a certification authority, and personal privacy of users can be protected by using the tamper-resistant property of blockchains. Therefore, as the data stored in the blockchain cannot be tampered, and is real and reliable, the user does not need to provide the privacy information to the enterprise initiating the authentication, but can directly provide the privacy information to the authentication mechanism. After the authentication mechanism authenticates the private information of the user, the private information and the authentication result can be encrypted and written into the block chain.
When the enterprise needs the user to provide the authentication result, the enterprise can inquire through the verification code generated by the block chain. In this way, the enterprise cannot obtain the specific privacy information of the user, but still can realize the authentication of the user, thereby protecting the information security of the user. The technical solution of the present disclosure can be realized by the following embodiments, for example.
Fig. 1 illustrates a flow diagram of some embodiments of an authentication method of the present disclosure.
As shown in fig. 1, the method includes: step 110, sending an authentication instruction; step 120, receiving a verification code; and step 130, obtaining the result of the authentication.
In step 110, an authentication indication is sent to the user to be authenticated. For example, the user needs to register in an enterprise, the enterprise needs to authenticate the identity information of the user, and then a corresponding authentication instruction is sent to the user.
In step 120, a verification code returned in response to the authentication instruction is received, the verification code is generated after the authentication mechanism authenticates the identity information of the user, and the authentication result and the identity information are stored in the blockchain.
In some embodiments, the user generates an authentication application according to the received authentication instruction, and the authentication application includes an identification of the enterprise and identity information of the user. The authentication application may further include an authentication item, an application time, and the like. The user can send the authentication application to a block chain node (such as an authentication platform) arranged at the authentication mechanism side for authentication.
For example, the authentication item may be real-name authentication, that is, authentication of a real name of a user, or may be authentication of a mobile phone number, a bank card number, or the like of the user. The identity information of the user may be, for example, an identification number, a passport number, a driver license number, or the like, which can uniquely identify the user. When an enterprise needs to authenticate a user, the user directly sends identity information to an authentication mechanism, so that the privacy information of the user is prevented from being leaked to the enterprise.
For example, the authentication platform may generate a corresponding passcode in response to the user being authenticated. For example, the certification authority certifies the corresponding certification items according to the certification application of the user. The verification code is associated with the authentication and the enterprise initiating the authentication, and the enterprise can inquire the authentication result through the verification code. If the user is not authenticated, a non-authentication notification may be returned to the user or enterprise.
In some embodiments, the authentication result, the verification code, the identity information, and the identity of the enterprise may be stored in a blockchain. It is also possible to store not the identity information but a digest of the identity information. The digest may be, for example, the result of performing a hash algorithm (e.g., sha 256) on the identity information. The digital signature may be the result of encrypting the digest by a private key, for example. One or more of the authentication time, the digital signature, and the like may also be stored in the blockchain.
In some embodiments, the verification code may be a public key, and the identity information and the authentication result are encrypted by using a private key matched with the public key and then stored in the block chain. For example, each certification authority that sets the blockchain node has its own public key and private key. And encrypting the identity information written into the block chain and the authentication result by using a private key corresponding to the authentication mechanism to form a digital signature, wherein the digital signature has non-repudiation and can ensure the safety of the information.
In step 130, the result of authentication is obtained from the blockchain using the verification code. For example, the verification code may be forwarded by the user to the enterprise that initiated the authentication. In the above embodiment, the public key matching the private key may be published to the authenticating user, the user may provide the public key to the enterprise through the encryption channel, and the enterprise may verify the data signature by using the public key to obtain the authentication result. Therefore, the authentication related information is issued to each node of the blockchain through the blockchain, and each node commonly has the backup of the identity information to prevent tampering, so that the reliability of authentication is enhanced.
In some embodiments, the authentication platform may modify the identity information stored in the blockchain before the enterprise authenticates the user.
For example, the authentication platform may modify the identity information stored in the blockchain according to an information change application sent by the user. For example, the information change application may include the type of information to be changed, the identity information after the change, the change time, and the like. And after receiving the information change application, the certification authority compares the changed identity information with the identity information of the user stored in the block chain. If the change condition is satisfied, the type of information to be changed, the identity information after the change, the change time, and the like are written into the block chain. Each node of the block chain can record all information modification history of the current user so as to prevent information tampering.
In some embodiments, a new verification code may be generated for the modified identity information and stored in the blockchain. For example, a new public key may be generated based on the modified identity information and a new verification code may then be sent to the enterprise. For example, the public key may be sent to a private device designated by the user through an encryption channel, and the user provides the public key to the enterprise, so that the enterprise can query the authentication result through the public key. In some embodiments, the user may verify the digital signature in the blockchain using the public key after receiving the public key, and the blockchain feeds back the digital signature verification result to the user.
It should be noted that, the user may perform identity authentication and obtain the verification code on the authentication platform in response to the authentication instruction of the enterprise, or may perform identity authentication and obtain the verification code on the authentication platform in advance, and the enterprise returns the obtained verification code to the enterprise after sending the authentication instruction to the user.
In the above embodiments, the user's private information is stored and authenticated in combination with the blockchain technique and the encryption technique. The enterprise initiating the authentication can only obtain the authentication result, so that the privacy information of the user can be prevented from being tampered and leaked, and the information security of the user is ensured.
Fig. 2 illustrates a block diagram of some embodiments of an authentication device of the present disclosure.
As shown in fig. 2, the authentication apparatus 2 includes a transmitting unit 21, a receiving unit 22, and an acquiring unit 23.
The transmission unit 21 transmits an authentication instruction to the user to be authenticated. The receiving unit 22 receives a verification code returned in response to the authentication instruction, the verification code is generated after the authentication mechanism authenticates the identity information of the user, and the authentication result and the identity information are stored in the block chain. For example, the authentication code is returned by the user. And the acquisition unit is used for acquiring the authentication result from the block chain by using the verification code.
In some embodiments, the verification code is a public key, and the identity information and the authentication result are stored in the blockchain after being encrypted by a private key matched with the public key. Instead of storing the identity information, a digest (e.g., a hash value) of the identity information may be stored in the blockchain. For example, the identity information stored in the blockchain may be modified according to an information change application sent by the user.
In the above embodiments, the user's private information is stored and authenticated in combination with the blockchain technique and the encryption technique. The enterprise initiating the authentication can only obtain the authentication result, so that the privacy information of the user can be prevented from being tampered and leaked, and the information security of the user is ensured.
