Abstract
The invention discloses an identity authentication method based on a block chain, which comprises the following steps: the user accesses the service of the third-party trusted certification authority through the safety equipment; the third-party trusted certification authority provides identity true implementation and other detection; the DID generator generates a user unique distributed ID according to requirements; and registering the user with the intelligent contract on the identity chain, and storing the DID and the public key and the identification of the third-party trust authority. The invention has the beneficial effects that: the uplink did is not tamper-evident. Through the characteristics of a block chain timestamp, distributed storage, an encryption algorithm and the like, once the did is uplinked, the did cannot be tampered truly; the uplink did is not deletable. The hash of the contract is stored in multiple ways on the chain, and any party cannot be deleted completely, so that the data security is guaranteed; the multiple parties are witnessed. Data is stored in multiple parties, all parties can achieve consensus through certain data management standard requirements, and the whole flow credibility problem of the electronic contract in generation, storage and use is jointly guaranteed; high safety. Only private key signature verification is needed on the block chain, so that privacy disclosure is prevented, and data safety is guaranteed.
Description
Technical Field
The invention relates to the technical field of information, in particular to an identity authentication method based on a block chain.
Background
The blockchain technology is a technical scheme for decentralized and collective maintenance of a distributed account book, and is essentially a distributed database system with a plurality of nodes participating together, the blockchain is not a single technology, but a result of multi-technology integration, a reliable and difficult-to-tamper account book record is maintained by using the blockchain, trust risk can be reduced, and maintenance cost of many participants is effectively reduced. When the data is stored through the block chain, the consensus among multiple parties is required to be obtained, and the data cannot be falsified or forged after the data is chained.
The existing identity authentication is stored in a centralized database of a third party, the third party may modify data, trust problems are easy to occur, and when disputes occur, the verification speed of calling results from the third party is slow, and the efficiency is low. Multiple uses require multiple registration submissions.
Disclosure of Invention
In view of the deficiency of the prior art, the invention is a method of identity authentication based on a block chain, and the purpose is to enable a user to log in by a private key, to cooperate with a third party more safely, to enable the user to enjoy dapp (distributed application) on the block chain by DID, and to enable the user to generate DID by an identifier under the user line, and then the user can obtain the self data summary on the whole chain.
In order to achieve the purpose, the technical scheme adopted by the invention is as follows:
a method of blockchain-based identity authentication, the method comprising:
s1, the user accesses the third-party trusted certificate authority service through the security device;
s2 the third-party trusted certification authority provides identity true-implementation detection and the like;
s3, generating a user unique distributed ID by a DID generator according to requirements;
s4 registers the user with the intelligent contract on the identity chain, saves the DID and public key, and the third party trust authority identification.
It should be noted that, in step 3, the DID is generated according to a random algorithm and a rule, and the user registers and then uses the service.
It should be noted that, in the step 3, the DID is generated according to a random algorithm and rules, and in the step 3, the DID is generated according to the offline unique data, so that the user can uplink the previous data, and after registration, all the data of the user can be unified, including the data retrieval before registration.
The invention has the beneficial effects that:
1. the uplink did is not tamper-evident. Through the characteristics of a block chain timestamp, distributed storage, an encryption algorithm and the like, once the did is uplinked, the did cannot be tampered truly;
2. the uplink did is not deletable. The hash of the contract is stored in multiple ways on the chain, and any party cannot be deleted completely, so that the data security is guaranteed;
3. the multiple parties are witnessed. Data is stored in multiple parties, all parties can achieve consensus through certain data management standard requirements, and the whole flow credibility problem of the electronic contract in generation, storage and use is jointly guaranteed;
4. high safety. Only private key signature verification is needed on the block chain, so that privacy disclosure is prevented, and data safety is guaranteed.

Detailed Description
The present invention will be further described below, it should be noted that the present embodiment is based on the technical solution, and a detailed implementation manner and a specific operation process are provided, but the protection scope of the present invention is not limited to the present embodiment.
As shown in fig. 1, the present invention is a method for identity authentication based on a block chain, where the method includes:
s1, the user accesses the third-party trusted certificate authority service through the security device;
s2 the third-party trusted certification authority provides identity true-implementation detection and the like;
s3, generating a user unique distributed ID by a DID generator according to requirements;
s4 registers the user with the intelligent contract on the identity chain, saves the DID and public key, and the third party trust authority identification.
It should be noted that, in step 3, the DID is generated according to a random algorithm and a rule, and the user registers and then uses the service.
It should be noted that, in the step 3, the DID is generated according to a random algorithm and rules, and in the step 3, the DID is generated according to the offline unique data, so that the user can uplink the previous data, and after registration, all the data of the user can be unified, including the data retrieval before registration.
It should be further noted that the identity authentication did is generated, and the algorithm for generating the unique data based on the offline is other similar unique data.
Various other changes and modifications to the above-described embodiments and concepts will become apparent to those skilled in the art from the above description, and all such changes and modifications are intended to be included within the scope of the present invention as defined in the appended claims.
Claims (3)
1. A method for identity authentication based on a blockchain, the method comprising:
s1, the user accesses the third-party trusted certificate authority service through the security device;
s2 the third-party trusted certification authority provides identity true-implementation detection and the like;
s3, generating a user unique distributed ID by a DID generator according to requirements;
s4 registers the user with the intelligent contract on the identity chain, saves the DID and public key, and the third party trust authority identification.
2. The method for identity authentication based on blockchain according to claim 1, wherein in the step 3, the DID is generated according to a random algorithm and rule, and the user registers and then uses the service.
