In order to preferably illustrate fingerprint sharing method of the present invention, the realization that fingerprint module in the prior art is described below is former Reason.In the prior art, when setting fingerprint on mobile terminals, its process is:Fingerprint module gathers fingerprint image, then utilizes spy Levy extraction algorithm and feature point extraction is carried out to fingerprint image, obtain fingerprint feature information, the fingerprint feature information is used as user's body Part checking reference information when be designated as fingerprint template information, then using mobile terminal itself AES (such as AES256 the fingerprint feature information after being encrypted, this reality) are encrypted to the fingerprint feature information (i.e. fingerprint template information) Apply in example and the fingerprint feature information after encryption is designated as standard fingerprint Template Information, the standard fingerprint Template Information is stored in movement Encryption memory block (secure world) in terminal, and fingerprint image will not preserve, that is, what is preserved when setting fingerprint only marks Quasi- fingerprint template information.It should be noted that encryption chip has unique key, this key is when chip dispatches from the factory By disposable fusing write-in, therefore it can not can only write and delete from outside reading and modification, namely standard fingerprint Template Information Remove, can not read and change, will not also be uploaded to any server, will not more be read by any third party's program.Fingerprint is set After the completion of, when user is operated by fingerprint, the fingerprint module on mobile terminal can enter to the fingerprint image currently inputted Row feature point extraction and cryptographic calculation, then by the fingerprint template information being calculated and the standard fingerprint in encryption memory block Template Information is compared, to judge that whether the fingerprint that currently inputs is legal, then notifies fingerprint comparison result to third party Application program, such as unlocked by fingerprint program or Alipay.The present invention is in order to realize that fingerprint is shared, to encrypting memory block (secure World) improved so that encrypting the data of memory block can be read, and operation can be decrypted.

Based on above-mentioned principle, in of the invention, if the algorithm phase of the fingerprint module of current mobile terminal and request mobile terminal Together, then fingerprint template information is only sent to request mobile terminal, the fingerprint template information is initial in current mobile terminal Fingerprint image is calculated through feature extraction algorithm.Illustrated by taking mobile terminal A and mobile terminal B as an example, in user couple When mobile terminal A carries out setting fingerprint during Initialize installation, fingerprint module can gather fingerprint image (i.e. initial fingerprint figure Picture), feature extraction is then carried out to the initial fingerprint image by feature extraction algorithm, fingerprint feature information is obtained and (is also denoted as Fingerprint template information), standard fingerprint Template Information is obtained after being then encrypted by the AES of mobile terminal itself simultaneously It is stored in encryption memory block.When mobile terminal A obtains fingerprint template information, its detailed process includes:(1) from encryption memory block Read standard fingerprint Template Information;(2) the standard fingerprint Template Information is carried out by pre-stored decipherment algorithm and key Decrypt to obtain the fingerprint template information.After mobile terminal B receives fingerprint template information, the fingerprint on mobile terminal B The current finger print image of module collection user's input, then current finger print image is carried out using the feature extraction algorithm of itself special Sign extraction, obtains fingerprint feature information, the fingerprint template for afterwards sending over obtained fingerprint feature information and mobile terminal A Information is compared, because mobile terminal A is identical with the algorithm of mobile terminal B fingerprint module, therefore by comparing fingerprint mould Plate information can determine whether the current finger print image on mobile terminal B and the initial fingerprint image on mobile terminal A are consistent, if The two is consistent, then authentication by, if the two is inconsistent, authentication failure, it is achieved thereby that mobile terminal A is by fingerprint Share to mobile terminal B.

Second sharing module 404, for when judged result is algorithm difference, obtain the fingerprint template information and The feature extraction algorithm is simultaneously sent to the request mobile terminal, so that the current finger that the request mobile terminal will collect Print image is compared through the fingerprint feature information that the feature extraction algorithm is calculated with the fingerprint template information.

Wherein, if the algorithm of fingerprint module of the current mobile terminal from asking mobile terminal is different, need fingerprint mould Plate information and feature extraction algorithm are sent to request mobile terminal simultaneously.Illustrate by taking mobile terminal A and mobile terminal B as an example, when After mobile terminal B receives fingerprint template information and feature extraction algorithm, mobile terminal B fingerprint module collection user's input Current finger print image, feature then is carried out to current finger print image using the feature extraction algorithm that mobile terminal A is sended over and carried Take, obtain fingerprint feature information, the fingerprint template information for afterwards sending over obtained fingerprint feature information and mobile terminal A It is compared, if the two is consistent, authentication is by the way that if the two is inconsistent, authentication fails, it is achieved thereby that mobile Fingerprint is shared to mobile terminal B by terminal A.Wherein, it is the reason for mobile terminal A transmissions feature extraction algorithm:Mobile terminal A with The algorithm of mobile terminal B fingerprint module is different, therefore even if current finger print image on mobile terminal B with mobile terminal A Initial fingerprint image it is identical, its comparison result also can be inconsistent, be this mobile terminal A and mobile terminal B on algorithm need It is identical, therefore its feature extraction algorithm is also sent to mobile terminal B by mobile terminal A while fingerprint template information is sent.

By above-mentioned module 401-404, the fingerprint that fingerprint shared routing of the present invention is realized between two mobile terminals is total to Enjoy, avoid be of little use in user, newly buy or belong to other people mobile terminal on using fingerprint when need Initialize installation The problem of fingerprint, user's operation is simplified, improves Consumer's Experience;And by judging current mobile terminal and request mobile terminal Fingerprint module whether algorithm is identical, and when algorithm is identical share fingerprint template information, in algorithm difference, sharing feature carries Algorithm and fingerprint template information are taken, causes asking for fingerprint recognition mistake so as to avoid two mobile terminals because algorithm is different Topic.

Further, the first embodiment based on the invention described above fingerprint shared routing 400, proposes that fingerprint of the present invention is shared The second embodiment of program 400.Fig. 4 is refer to, Fig. 4 is the functional module of the second embodiment of fingerprint shared routing 400 of the present invention Schematic diagram, compared with first embodiment, in the present embodiment, fingerprint shared routing 400 also includes link block 405 and principle is sentenced Disconnected module 406.In the present embodiment, each functional module is described as follows:
