Description
Technical field
The present invention relates to intelligent building field, be specifically related to a kind of wireless access control system based on finger vena identification.
Background technology
Along with improving constantly of people's living standard, the value of daily living article also constantly promotes, and people also pay attention to all the more for anti-theft measure, and along with the variation of means of crime, traditional mechanical lock cannot be guaranteed security.A lot of residential quarters are all equipped with the antitheft door of Magnetic Control downstairs, and a lot of antitheft doors is by input password, or magnetic card opens, thereby guarantee antitheft security.But in life, password easily leaks, and magnetic card also can be lost, this has increased uncertain factor all to the security of antitheft door, to our life, has brought potential safety hazard.
Conventional identity recognizing technology has fingerprint recognition, recognition of face, the identification of palm shape and signature identification at present, but all has certain limitation, as described below:
1, fingerprint recognition: everyone (comprising fingerprint) skin lines is different on pattern, breakpoint and point of crossing is unique feature and constant throughout one's life.Rely on this uniqueness and stability features, just a people can be mapped with his fingerprint.By relatively his fingerprint and the fingerprint of preservation in advance, compare, carry out authentication, Here it is fingerprint identification technology.Its shortcoming is: easily damage, easily forgery, contact collection.
2, recognition of face: recognition of face is an important directions of biological characteristic authentication technique, has obtained research widely now.Its shortcoming: discrimination is low; Affected greatly by light, attitude and expression shape change.Set up a face identification system and remain a very difficult problem.
3, palm type identification: palm type recognition technology is that U.S. doctor CARRETT is pioneering after biometrics identification technology test for many years.The three-dimensional shape of human palm, as fingerprint, is that everyone is mutually different, therefore can be used as the recognition feature of identity validation.Palm feature refers to the size and shape of hand, and it comprises length, width, the thickness of hand, and the surface characteristics of palm and all the other four fingers except thumb.Palm shape recognition system is by infrared ray and CMOS scanning, to obtain the 3-D view of palm, measure the data of more than 90 palm shape, and then analysis draws the unique feature of palm.Similarity is poor; Harvester volume is large; Ease for use is poor; Must contact use.
4, signature identification: signature has been used the centuries as the means of authentication, and we all very familiar in the form list of bank signature as the sign of our identity.By signature digitizing, be such process, the action of measurement image itself and whole signature---different speed, order and pressure between each letter and letter, signature identification is the same with voice recognition, is that a kind of behavior determination is learned.Its shortcoming: signature character is unstable; Increase other safe ancillary methods; Harvester complex structure, costliness; Be difficult to its compact in size.
