CN103207963A - Two-factor authentication system based on fingerprint and vein recognition - Google Patents

Abstract

The invention discloses a two-factor authentication system based on fingerprint and vein recognition. The two-factor authentication system comprises a vein acquisition unit and a fingerprint acquisition unit which are mounted in a same apparatus, wherein a vein module and an external communication interface connected with each other are arranged in the vein acquisition unit; a fingerprint module, a control/network transmission module and an external communication interface are arranged in the fingerprint acquisition unit and are connected with one other; and the vein module is connected with the fingerprint module. A vein algorithm processing unit is used for primarily authenticating identity of a user; then a fingerprint of the user is acquired; and a fingerprint algorithm processing unit is used for finally determining whether the user has authority. Through vein and fingerprint authentication, the two-factor authentication system provided by the invention can effectively prohibit counterfeiting fingerprints, and can widely expand the application space of fingerprint and vein recognition.

Description

Fingerprint adds vein identification double verification system

Technical field

The present invention relates to a kind of verification system, relate in particular to a kind of fingerprint and add vein identification double verification system.

Background technology

Ubiquitous at a password, the epoch that problem is spread unchecked such as spy upon, crack, usurp for one.No matter be bank, enterprise or community's gate control system, or personal card and computer landing approach, the safeguard protection mode that password is most widely used beyond doubt.Even if the password that becomes increasingly complex allows the people feel safety, people is in the face of too many password, also can occur memory chaotic, problem such as forget.Expedite the emergence of thus and have more safety, maintain secrecy and the appearance of the biological identification technology of convenience such as recognition of face, iris recognition, fingerprint recognition etc.Wherein, though fingerprint recognition application public attention is just strong, equally easily by counterfeit and stolen; The individuality that has can't be identified because fingerprint characteristic seldom, perhaps under specific conditions, as is pointed humidity, breakage etc.; Many people share Fingerprint Identification Unit, also can bring health concerns such as spread of germs.

Existing recognition system is independent finger recognition system or independent vein recognition system.And use maximum fingerprint recognition antifalsifications relatively poor, accurate inadequately for the fingerprint identification of forging.The shortcoming that can't prevent false fingerprint is arranged, and that the recognition system cost that can prevent false fingerprint is compared cost is higher, it is bigger to promote resistance.

Summary of the invention

The objective of the invention is to solve the problems of the prior art, provide a kind of fingerprint safe and reliable, that antifalsification has the double verification function more by force to add vein identification double verification system.

Technical scheme of the present invention is: a kind of fingerprint adds vein identification double verification system, comprises vein collector and fingerprint capturer, and described vein collector and fingerprint capturer are installed in the same equipment; Establish interconnective vein module and external communication interface in the described vein collector; Be provided with fingerprint module, control/network transmission module and external communication interface in the described fingerprint capturer, described fingerprint module, control/network transmission module and external communication interface are joined; Described vein module is connected with described fingerprint module.

Described vein module comprises vein taking unit and vein algorithm process unit, and described vein taking unit is connected with vein algorithm process unit.

Described vein collector is the finger vena collector.

Described fingerprint module comprises finger print imaging unit and fingerprint algorithm processing unit, and described finger print imaging unit is connected with the fingerprint algorithm processing unit.

Described fingerprint capturer is the finger print collector.

The present invention has following beneficial effect:

(1) carry out the vein collection by live finger, because vein is hidden in body interior, the probability that is replicated or usurps is very little, has the height antifalsification;

(2) it is higher that vein is gathered accuracy, and user's psychological reactance is low, thereby is subjected to the factor of physiology and environmental impact also low;

(3) use the vein collection to identify fast;

(4) tentatively judge identity by vein algorithm process unit, gather finger print again, by the fingerprint algorithm processing unit, whether final affirmation has the right to limit, by vein and fingerprint recognition double authentication, can effectively stop false proof fingerprint, the expansion of bigizationner the application space of fingerprint, vein identification.

Embodiment

For technological means, technical characterictic, goal of the invention and the technique effect that the present invention is realized is easy to understand, below in conjunction with concrete diagram, further set forth the present invention.

A kind of fingerprint adds vein identification double verification system as shown in Figure 1, comprises vein collector and fingerprint capturer, and vein collector and fingerprint capturer are installed in the inside ofsame equipment 100, and with thisequipment 100 outside other 101 long-range connections of application apparatus; The vein collector that adopts among the present invention is the finger vena collector.In the vein collector, establishinterconnective vein module 200 and external communication interface (not shown); In fingerprint capturer, be provided withfingerprint module 300, control/network transmission module 400 and external communication interface (not shown).Fingerprint module 300, control/network transmission module 400 and external communication interface are joined.

Comprisevein taking unit 201 and veinalgorithm process unit 202 as Fig. 2vein module 200, describedvein taking unit 201 is connected with veinalgorithm process unit 202, when the outside live finger ofvein module 200 inductions, 201 pairs of live finger veins of vein taking unit are gathered, judge identity by veinalgorithm process unit 202 then, and the data of preserving in the vein gathered and the database are compared.

If the vein data message of coupling is arranged then can send corresponding prompting, directly enter fingerprint capturer and carry out fingerprint collecting.If not with its data message that mates mutually then can report an error operation that can not be follow-up.

Fingerprint module 300 comprises fingerprint imaging unit 301 and fingerprintalgorithm processing unit 302, the fingerprint imaging unit 301 line data transmission of going forward side by side that is connected with fingerprint algorithm processing unit 302.Start fingerprint module 300 based on the smooth operation ofvein module 200, when entering fingerprint capturer and gather, the 301 pairs of fingerprints in finger print imaging unit carry out capture, then the fingerprint that collects are sent to fingerprintalgorithm processing unit 302 and carry out analysis and judgement.

As the finger print information of gathering and databases information matches then can finish whole verification process smoothly, and information is sent to control/network transmission module 400 complete operations; If the finger print information of gathering and the information in the database misfit, then can report an error, prompting reenters or direct terminating operation.

Only being preferred embodiment of the present invention in sum, is not to limit practical range of the present invention.Be that all equivalences of doing according to the content of the present patent application claim change and modification, all should belong to technology category of the present invention.
