Structure is divided into three parts, is intelligent contract block chain account address, data division and program part respectively, and the program part is
According to the procedure script that the content of ID authentication request is generated.The |input paramete of the script is the above-mentioned certification factor, output result
It is the result for carrying out presetting mathematic(al) manipulation to the above-mentioned certification factor.Wherein, the mathematic(al) manipulation including but not limited to plus, subtract with, different
Or with hash conversion etc..
Step S330：Intelligent contract is broadcast in block chain, and intelligent contract block chain account address is sent to
User terminal.
Specifically, intelligent contract is broadcast in block chain, wherein as the first transaction, the output of the first transaction includes intelligence
The block chain account address of contract, the cryptographic Hash of intelligent contract and the operation result after presetting computing can be carried out.Such intelligence
Energy contract is operated in block chain network, is a set of promise for defining in digital form, and block chain becomes the participant of contract, is born
Duty is safeguarded and preserves contract, and is executed automatically.Meanwhile, after intelligent contract is generated, by the block chain account address of the intelligent contract
User terminal is sent to, facilitates the execution of subsequent step.The effect of step S330 is the block chain account ground of intelligent contract
Location is supplied to user terminal, and the specific embodiment of the step can be flexibly set according to practical situation by those skilled in the art
Put, as long as above-mentioned purpose can be reached, the present invention is not especially limited to this.
Step S340：The implementing result for obtaining after intelligent contract is executed using the certification factor according to user terminal carry out identity
Certification；Wherein, when implementing result is mated with operation result, confirm authentication success；When implementing result with operation result not
During coupling, authentication failure is confirmed.
Wherein, user terminal executes concretely comprising the following steps for intelligent contract using the certification factor：User terminal is handed over by second
Easily executing intelligent contract, input of second transaction including the block chain account address of user terminal, second transaction defeated
Go out block chain account address and the certification factor including intelligent contract.
In the present embodiment, executed the implementing result for obtaining after intelligent contract is carried out according to user terminal using the certification factor
The step of authentication, is specially：Obtaining intelligent contract carries out obtaining after default computing according to the certification factor that user terminal is provided
Implementing result and implementing result mated with operation result after matching result, identity is carried out according to the matching result and is recognized
Card.Wherein, when implementing result is mated with operation result, confirm authentication success；When implementing result and operation result not
Timing, confirms authentication failure.
In sum, a kind of identity identifying method based on block chain that the embodiment of the present application is provided can be by authentication information
Store in the intelligent contract in block chain.Thus one, on the one hand, the intelligent contract itself in block chain network can be utilized
Characteristic, it is ensured that authentication information cannot be tampered；On the other hand, using intelligent contract internal processes, authentication verification information is executed
Operation, so as to improve safety during authentication further.As can be seen here, the identification authentication mode in the embodiment of the present application
Possesses splendid safety.
