Description
Technical field
The present invention relates to a kind of identity identifying method of block chain in conjunction with biological characteristic.
Background technique
In the epoch of current information-based outburst, how to determine that a person's identity, protection information security become urgently to be resolved
Critical issue.It is most traditional that identity authentication method is realized by username and password, since username and password is easily forged
And loss, it is increasingly difficult to meet the requirement of people, to gradually be eliminated.In recent years, based on the authentication of biological characteristic
As the mainstream in epoch, such as fingerprint, iris, face.Biological characteristic not only has uniqueness but also convenient not easy to lose, simultaneously
It is also easy to cooperation computer and safety, monitoring, management system integration, realizes automatic management.But its there are the problem of also show and
Be clear to, the present identity identifying method based on biological characteristic be mostly using stencil matching, template library management and maintenance and
Its safety problem is that us is worth to pay close attention to.With the rapid development of information technology, more and more template libraries attacked or
It distorts, the existing identity identifying method security risk based on biological characteristic is stepped up.
Summary of the invention
It is an object of the invention to, based on deficiency existing for biometric identity Verification System, provide a kind of area for existing
Identity identifying method of the block chain in conjunction with biological characteristic.Block chain technology is introduced, using the decentralization of block chain and can not be distorted
Characteristic, by biometric image cryptographic Hash be stored on block chain substitute traditional identity certification in biological characteristic template library,
It can be effectively solved template library to be subject to attack or distort to give authentication bring security risk.
In order to achieve the goal above, conception of the invention is:
This method is divided into two major parts, and first part is registration phase, needs to three fingerprint images of same finger collection,
Each fingerprint image cryptographic Hash is obtained, and will be in cryptographic Hash storage to block chain.Second part is authentication phase, i.e., when will register
The fingerprint image of acquisition carries out characteristic value with the fingerprint image of collection in worksite and matches and analysis, realization authentication.
Conceived according to foregoing invention, the present invention adopts the following technical solutions:
A kind of identity identifying method of block chain in conjunction with biological characteristic, the specific steps are as follows:

When finger print image；
Step 3, by fingerprint characteristic value extraction and matching algorithm, registered fingerprint image and the scene extracted from block chain are adopted
The fingerprint image of collection extracts characteristic value, then matches to characteristic value, obtains matching score, confirms identity.
Registered fingerprint image cryptographic Hash is stored in the specific steps on block chain by the step 1 are as follows:
Step 1-1 is acquired by fingerprint capturer and accredited personnel's fingerprint and is exported fingerprint image, then it is pre-processed, two
Value, Refinement operation；
Step 1-2 writes the Promise function for uploading fingerprint image, fingerprint image is uploaded to IPFS, and return to fingerprint image
Cryptographic Hash repeatedly uploads different fingerprint images and obtains multiple cryptographic Hash, thus one fingerprint Hash library of building；
By calling set function in intelligent contract example block chain is written in the Hash library of fingerprint image by step 1-3.
The step 2 inputs user name and cryptographic Hash carries out first layer verifying, after first layer is verified, from block chain
Registered fingerprint image cryptographic Hash needed for extracting, then registered fingerprint image is extracted from IPFS by the cryptographic Hash, while scene is adopted
Finger print image when collection registration.Specific steps are as follows:
Step 2-1 inputs user name and Hash in two input frames of the front end login interface of React language design respectively
Value；
After step 2-2, user name and cryptographic Hash input correctly, by calling the get function in intelligent contract example, from block chain
The middle cryptographic Hash for reading registered fingerprint image, recycles the cryptographic Hash to extract corresponding fingerprint image from IPFS；
Step 2-3, finger print image when collection in worksite is registered.
The step 3 is extracted by fingerprint characteristic value and matching algorithm, the registered fingerprint image that will be extracted from block chain
Characteristic value is extracted with the fingerprint image of collection in worksite, then characteristic value is matched, matching score is obtained, confirms identity.Really
Recognize the specific steps of identity are as follows:
Step 3-1, fingerprint image extracts characteristic value when to the registration extracted in step 2-2；
Step 3-2 extracts characteristic value to the fingerprint image of collection in worksite in step 2-3；
Step 3-1 is matched score using matching algorithm acquisition with the characteristic value that step 3-2 is obtained, to matching score by step 3-3
It is analyzed, judges whether it is same people, to confirm identity.
The present invention has following obvious substantive distinguishing features and significant technological progress compared with prior art:
The present invention utilizes with decentralization, can not distort the block chain storage fingerprint cryptographic Hash of characteristic instead of template library, peace
Full performance greatly improves, and avoids the risk that template library is attacked or distorted.The characteristics extraction and matching algorithm technology used
Very mature, the characteristic value number of extraction is more, can directly give matching score by characteristic value matching algorithm, and accuracy rate compared with
It is high.
Detailed description of the invention
Fig. 1 is the flow diagram of the method for the present invention.
Specific embodiment
With reference to the accompanying drawing, specific embodiments of the present invention are described further.
As shown in Figure 1, a kind of identity identifying method of block chain in conjunction with biological characteristic, the specific steps are as follows:
Step 1, registered fingerprint image Hash library is stored on block chain, specific steps are as follows:
Step 1-1 is acquired by fingerprint capturer and accredited personnel's fingerprint and is exported fingerprint image, then it is pre-processed, two
Value, Refinement operation.
Step 1-2 writes the Promise function for uploading fingerprint image, fingerprint image is uploaded to IPFS, and return to fingerprint
Image cryptographic Hash repeatedly uploads different fingerprint images and obtains multiple cryptographic Hash, thus one fingerprint Hash library of building；Obtain these
The specific code of information is as follows:
((response) // reader is the fingerprint image uploaded to ipfs.add (reader) .then, calls ipfs.add letter
Fingerprint image is uploaded to IPFS by number；
This.saveImageOnIpfs (reader) .then ((hash) // call this.saveImageOnIpfs that will refer to
Print image is stored on IPFS and returns to cryptographic Hash；
This.setState ({ imgHash:hash }) // store the cryptographic Hash of return into state machine variable imgHash.
By calling set function in intelligent contract example block chain is written in the Hash library of fingerprint image by step 1-3；
