Description
Technical field
The present invention relates to Automatic FingerprintVerification field, particularly relate to the cryptographic system based on multiple fingerprints identification and its implementation.
Background technology
In recent years, biological identification technology is paid close attention to widely, is considered to the final technology of automatic identification.Wherein auto Fingerprint Identification System is biological identification technology the most ripe at present, and the uniqueness of fingerprint and stability are used as the Main Basis of checking personal identification by people, have vast potential for future development.Auto Fingerprint Identification System crosses over one of disciplinary study hot issues such as image procossing, pattern-recognition and Computer Database, and its achievement in research is widely used in the administration of justice, public security and various security protection system.
Summary of the invention
In order to solve technical matters existing in background technology, the present invention proposes a kind of cryptographic system based on multiple fingerprints identification and its implementation, fingerprint recognition is carried out by software, user can set the fingerprint recognition that many fingers carry out arbitrary arrangement combination as required, generating cipher, comprises multiple fingerprints and has that the password of input sequence generates, password stores and the identification of password.
Technical solution of the present invention is: based on the cryptographic system of multiple fingerprints identification, it is characterized in that: the core microprocessor that described system comprises fingerprint sensor and is connected with fingerprint sensor, described fingerprint sensor identification fingerprint, generating cipher; Described core microprocessor recognition code.
Based on the password implementation method of multiple fingerprints identification, it is characterized in that: said method comprising the steps of:
1) fingerprint sensor carries out fingerprint collecting, obtains fingerprint characteristic;
2) fingerprint number is generated multiple fingerprints encrypted message with fingerprint input sequence and together with collected fingerprint feature information, and information is stored;
3) password identification is carried out: according to the collection to fingerprint to be identified, obtain the characteristic information of the number of fingerprint to be identified, fingerprint input sequence to be identified and fingerprint to be identified, core microprocessor mates with the finger-print cipher information of storage the encrypted message of fingerprint to be identified, and the information of judging whether conforms to.
The setting of above-mentioned multiple fingerprints password, inputs the fingerprint of a people or many people combination as required, reaches the sign-off operation be combined with password.
Said method also comprises step 1.1) two fingerprints or multiple fingerprint are placed on finger-print recognising instrument simultaneously and identify.
Advantage of the present invention is: adopt core microprocessor, a fingerprint sensor, carries out fingerprint recognition by software.Fingerprint to be identified comprises the input sequence of multiple fingerprints, fingerprint number and fingerprint feature information, and these information are mated with the finger-print cipher information set in internal memory by core microprocessor, judge whether to conform to, thus realize fingerprint recognition and authentication.User can set the fingerprint recognition that many fingers carry out arbitrary arrangement combination as required, generating cipher, comprises multiple fingerprints and has that the password of input sequence generates, the identification of password storage and password.

Embodiment
A kind of cryptographic system based on multiple fingerprints identification of the present invention and its implementation, it mainly adopts core microprocessor 2, and a fingerprint sensor 1, carries out fingerprint recognition by software.User can set the fingerprint recognition that many fingers carry out arbitrary arrangement combination as required, generating cipher, comprises multiple fingerprints and has that the password of input sequence generates, the identification of password storage and password.
The inventive method comprises multiple fingerprints collection, carries out fingerprint collecting by fingerprint collecting sensor, and carries out password setting, and password setting comprises repeatedly fingerprint input, and fingerprint input sequence and fingerprint number are with all composition encrypted messages of finger print information.
The reading of multiple fingerprints and stores processor, by the core microprocessor that is connected with fingerprint collecting sensor to the reading of the fingerprint collected and stores processor, take the fingerprint characteristic information, by the input sequence of fingerprint, fingerprint number and fingerprint feature information composition multiple fingerprints password.
Multiple fingerprints identification and authentication, fingerprint to be identified is gathered by fingerprint collecting sensor, fingerprint to be identified comprises the input sequence of multiple fingerprints, fingerprint number and fingerprint feature information, these information are mated with the finger-print cipher information set in internal memory by core microprocessor, judge whether to conform to, thus realize fingerprint recognition and authentication.
As shown in Figure 1, it is present system structural representation, and as seen from the figure, the cryptographic system of this multiple fingerprints identification comprises fingerprint sensor 1 and gathers fingerprint, generating cipher, and memory storage stores password, and kernel microcontroller 2 carries out fingerprint matching and fingerprint recognition.
As shown in Figure 2, it realizes schematic diagram for the inventive method, and as seen from the figure, the inventive method comprises following steps:
First, fingerprint number is generated multiple fingerprints encrypted message with fingerprint input sequence and together with collected fingerprint feature information, and these information are stored, when carrying out password identification, according to the collection to fingerprint to be identified, obtain the characteristic information of the number of fingerprint to be identified, fingerprint input sequence to be identified and fingerprint to be identified, core microprocessor mates with the finger-print cipher information of storage the encrypted message of fingerprint to be identified, the information of judging whether conforms to, thus reaches the object of multiple fingerprints identification.
As shown in Figure 3, it can realize sign-off operation process chart for the inventive method, and as seen from the figure, the setting of this multiple fingerprints password, can input the fingerprint of a people or many people combination as required, reach the object of the sign-off operation be combined with password further.
As shown in Figure 4, it refers to simultaneously identification for the inventive method realization more and refers to identify the process flow diagram that combines in order more, in order to better reach the object accurately identified, can carry out referring to identify simultaneously and refer to identify the method combined in order more more, and newly-increased pair of system refers to or many fingerprint recognition pattern, different with conventional fingerprint recognition mode, in fingerprint collecting and proof procedure, according to discrimination index while setting, can two fingerprints or multiple fingerprint be placed on finger-print recognising instrument simultaneously, system can automatically identify, thus collection verification efficiency is provided greatly, increase the accuracy of fingerprint authentication.
The present invention so design be because, the extraneous factor affecting fingerprint recognition is a lot, as old man, be engaged in manual labor or the fingerprint the wounded, Fingerprint recognition all may be made wrong, and many fingers identify simultaneously, if a finger is impaired, other finger available judges, like this, refer to identify more simultaneously, identify that fiduciary level is higher.
