Description
Technical Field
The invention relates to the technical field of block chain technology, in particular to a decentralized identity authentication and identification method based on block chain technology.
Background
Identity authentication is an important civil problem in the current society, and most of the people need to provide identity authentication to provide further services no matter the people are off-line banking institutions or government agencies, or on-line payment or social websites; due to the particularity of the identity authentication case, the requirements on confidentiality, accuracy and high efficiency are very high; when the information of the user is not leaked, the user needs to be provided with quick and accurate identity authentication to complete other further services;
the online banking solution used by the bank is essentially a private key signature solution, and is consistent with the existing private key signature solution of the block chain; however, the bank identifies the identity according to the information of the client, so that when the user loses the online bank, the bank can invalidate the online bank, namely abandon a certificate private key and open a new online bank to create a new certificate private key;
some users will put the assets in the exchange, in the prior art, after the user loses the password, the exchange can recover the control right of the account according to the mailbox of the client and the identity information of the client; however, this solution has a big disadvantage that the user needs 100% to believe that the exchange is not bad, because your property is controlled by 100% of the exchange, which reduces the security of the identity authentication and causes property loss, therefore, we propose a decentralized identity authentication identification method based on the block chain technology.
Disclosure of Invention
According to the technical problem, the invention provides a decentralized identity authentication and identification method based on a block chain technology, which is characterized by comprising a user module, a contract module and an identity identification service provider module, wherein the user module is connected with the contract module, the contract module is connected with the identity identification service provider module, and the identity identification service provider module is connected with the user module;
the number of the identity recognition service provider modules is N, wherein N is more than or equal to 2;
the user module is used for logging in user information and sending transaction information;
the contract module establishes identities of user information and transaction information and allocates a virtual address VA;
the plurality of identity recognition service merchant modules respectively carry out identity recognition authentication on the user, carry out signature on the virtual address VA through a private key and return data to the user;
a decentralized identity authentication and identification method based on block chain technology comprises the following specific operation procedures:
1. the user logs in the identity information of the user through the user module, after the login is successful, the user module is allocated to a control address addr1 of the user, the user sends a transaction to the contract module through the control address addr1 of the user to create the identity, the parameter is n/m, the contract module is allocated with a virtual address VA, the control address addr1 is participated by m identity recognition service provider modules, and the control address can be modified when the n identity recognition service provider modules feed back;
2. the user carries out identity identification authentication in a plurality of different identity identification facilitator modules, the exchange is provided with KYC information of the user, so that the identity authentication can be provided for the user, and when the user applies for the identity identification facilitator, the identity identification facilitator signs a virtual address VA by using a private key of the identity identification facilitator and returns data to the user module; the user sends the signed data to a contract module, and the contract module records the information of the identity recognition service provider;
3. the user repeats the operation for m times, for example, m is 3, and the user identifies the fire coin, the okex and the currency security; the three identity recognition service providers do not know KYC information of other identity recognition service providers, so that users can be different;
4. when the user loses or wants to change the control private key, the control address can be modified as long as the signatures of the n identification service provider modules are taken.
Further, any organization or individual may register as a facilitator as long as they can pay the deposit.
The invention has the beneficial effects that: the invention realizes a scheme different from a bank and a trading desk by setting the mutual connection of the user module, the contract module and the identity recognition service provider module and establishing a protocol on the block chain, so that the same user can retrieve the password through a plurality of different identity recognition service provider modules, and the information among the identity recognition service provider modules is not disclosed mutually, so that the user right of an account can be recovered, the safety of the account is improved to a certain extent, and the property loss is reduced;
through setting up a plurality of identification service merchant modules, and each identification service merchant module is independent each other, and the operation of malicious user asset of using can't be realized to a single identification service merchant module, guarantees the authenticity in the course of the work, can judge the legitimacy of official working.

the user module is used for logging in user information and sending transaction information;
the contract module establishes identities of user information and transaction information and allocates a virtual address VA;
the plurality of identity recognition service merchant modules respectively carry out identity recognition authentication on the user, carry out signature on the virtual address VA through a private key and return data to the user;
a decentralized identity authentication and identification method based on block chain technology comprises the following specific operation procedures:
1. the user logs in the identity information of the user through the user module, after the login is successful, the user module is allocated to a control address addr1 of the user, the user sends a transaction to the contract module through the control address addr1 of the user to create the identity, the parameter is n/m, the contract module is allocated with a virtual address VA, the control address addr1 is participated by m identity recognition service provider modules, and the control address can be modified when the n identity recognition service provider modules feed back;
2. the user carries out identity identification authentication in a plurality of different identity identification facilitator modules, the exchange is provided with KYC information of the user, so that the identity authentication can be provided for the user, and when the user applies for the identity identification facilitator, the identity identification facilitator signs a virtual address VA by using a private key of the identity identification facilitator and returns data to the user module; the user sends the signed data to a contract module, and the contract module records the information of the identity recognition service provider;
