Detailed Description
In order to make the objects, technical solutions and advantages of the present application more apparent, the technical solutions of the present application will be described in detail and completely with reference to the following specific embodiments of the present application and the accompanying drawings. It should be apparent that the described embodiments are only some of the embodiments of the present application, and not all of the embodiments. 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 application.
The technical solutions provided by the embodiments of the present application are described in detail below with reference to the accompanying drawings.
As shown in fig. 1, an embodiment of the present application provides an identity authentication method based on a blockchain, which is applied in an identity authentication system, where the identity authentication system has an identity authentication function, but may also include other functions, such as a transaction function and a login function, and is not limited herein. The identity authentication method comprises the following steps:
s101, determining a blockchain platform which is created in advance based on a blockchain framework in the identity authentication system.
The Blockchain (Blockchain) is a novel application mode of computer technologies such as distributed data storage, point-to-point transmission, a consensus mechanism, an encryption algorithm and the like, and is essentially a decentralized database.
A blockchain platform created based on the blockchain framework may first be determined. The blockchain frame may be any blockchain frame capable of implementing the corresponding function of the embodiment of the present application, for example, bitcoin, etherhouse, Fabric, Corda, and the like. A blockchain platform may refer to a platform that stores a blockchain, e.g., may be a distributed system, etc. Of course, the blockchain platform may also directly represent the blockchain itself, and is not limited herein.
The blockchain platform created based on the blockchain framework in the application is built in the identity authentication system. Of course, the identity authentication system may include a plurality of other devices, platforms, modules, etc. in addition to the blockchain platform.
S102, determining a management center built outside the block chain platform in the identity authentication system.
After the blockchain platform is determined in the identity authentication system, a management center set up on the blockchain platform can be determined in the identity authentication system. The management center is used for storing the private key of the user. If the user keeps the private key, the private key is easy to lose, and the private key can not be stored by the user due to the limitation of technical operation. The private key is stored in the management center, and the user can finish the storage of the private key only by trusting the management center.
S103, receiving a private key and an account password sent by a user, encrypting the private key through the account password, and storing the encrypted private key in the management center, wherein the management center does not store the account password.
Of course, if the private key is directly stored in the management center, the problem of privacy disclosure still cannot be solved. In general, except for the private key, the user has an account ID and an account password for logging in the account. Therefore, when the private key is transmitted, the account password corresponding to the private key can be transmitted together. And then after the identity authentication system receives the account password of the user, the private key can be encrypted through the account password, and then the encrypted private key is stored in the management center. And the management center does not store the account password, and the management center cannot decrypt the encrypted private key according to the account password, so that the privacy of the user is also ensured.
In particular, if the private key is stored in the management center only after being encrypted, there is still a risk of theft. Therefore, the private key may be first fragmented, i.e., the private key is divided into a plurality of parts, so as to obtain a plurality of sub-keys. And then storing the plurality of sub-keys in the blockchain platform after the sub-keys are respectively encrypted by the private keys. In the storage, the plurality of encrypted sub-keys may be stored in different places. For example, when the management center includes a plurality of storage devices, the management center may store the plurality of storage devices in different storage devices. When a plurality of administrators exist in the management center, the plurality of administrators can manage partial sub-keys.
And S104, receiving a transaction request sent by the user, and performing transaction in the blockchain platform through an account password included in the transaction request.
After receiving a transaction request sent by a user, the encrypted private key stored in the management center can be decrypted through the account password included in the transaction request, and then the private key of the user can be obtained. The user can then use the private key to conduct transactions in the blockchain platform or conduct corresponding operations. Because the management center is arranged in the identity authentication system, the management center can store the private keys of the users in the identity authentication system, so that the users can acquire the private keys when in use even if the users do not know how to keep the private keys. And the private key is encrypted through the account password, and the management center does not store the account password, so that the private key of the user cannot be stolen, and the privacy of the user is guaranteed.
And the corresponding intelligent contract can be generated in advance and deployed in the identity authentication system. The intelligent contract comprises at least one of an account password and a private key. The intelligent contract is used for determining a corresponding encrypted private key of the user in the management center; or according to the account password contained in the transaction request, decrypting the encrypted private key to obtain the private key; or through private keys, transactions are conducted in the blockchain platform. Since the intelligent contracts are public, each node can check whether the intelligent contracts conform to the preset contracts and deploy the intelligent contracts on the node. The user can inquire the intelligent contract through a corresponding way, so that the degree of automation of the transaction is improved, and the trust degree of the user is further increased. The intelligent contract can only be changed in an upgrading mode, each node needs to be synchronously deployed, once the intelligent contract is deployed, the intelligent contract can only be executed through a program, interference of human factors is avoided, and the reliability of data is enhanced.
In one embodiment, if the user forgets the account password owned by the user, the private key cannot be obtained through the account password. Therefore, the identity information corresponding to the user can be sent by the user, and then the identity information is associated with the private key and then stored in the management center. When the user forgets the account password and forgets the private key, the user can send a reset request carrying the own identity information, the identity authentication system can compare the identity information contained in the reset request after receiving the reset request, and if the identity information is consistent, the private key can be reset, so that the user can trade in the block chain platform according to the reset private key. The identity information can be real-name authentication information, and the identity information of the user can be guaranteed to be difficult to tamper through the real-name authentication information, so that the authenticity of the identity information of the user is guaranteed. The real-name authentication information may be information that can be used for real-name authentication, such as an identity card, a driver's license, a student's license, and the like.
In one embodiment, a regulatory body is also included in the identity authentication system. The supervision mechanism is used for supervising the management center and preventing privacy of the user from being revealed. The supervision authorities can comprise governments and supervision departments, and the supervision authorities supervise the management centers, so that the trust degree of people on the management authorities can be further increased, and the privacy disclosure can be further reduced.
As shown in fig. 2, an embodiment of the present application further provides an identity authentication device based on a block chain, which is applied in an identity authentication system, and the identity authentication device includes:
at least one processor; and the number of the first and second groups,
a memory communicatively coupled to the at least one processor; wherein the content of the first and second substances,

The embodiment of the present application further provides a nonvolatile computer storage medium for identity authentication based on a block chain, where a computer-executable instruction is stored and applied in an identity authentication system, where the computer-executable instruction is set as:
determining, in the identity authentication system, a blockchain platform that was created in advance based on a blockchain framework;
