Abstract
The invention designs a fingerprint collection instrument based on an audio interface of a smart phone or a tablet computer. The method is characterized in that an image generated by a fingerprint chip is coded and is converted into an analog signal; a smart phone or a tablet computer uses a recording function of an audio interface to transmit fingerprint data to the smart phone or the tablet computer; a fingerprint image is obtained by restoration based on software and drive and is provided for fingerprint authentication software. According to the invention, because the smart phone or the tablet computer of the user can be connected to fingerprint equipment conveniently, the smart phone or the tablet computer can utilize finger collection equipment to carry out identity authentication without the need of password memory, thereby improving security and convenience of the identity authentication.
Description
Technical field
The present invention relates to fingerprint hardware device and field of authentication, particularly adopt the fingerprint acquisition instrument based on smart mobile phone and panel computer audio interface
Technical background
Along with the progress of technology, smart mobile phone and panel computer are being played the part of more and more important role in people's work and life, and it is more and more important that the safety of mobile phone and panel computer also becomes.Because fingerprint typing module seldom is integrated on mobile phone or panel computer, mobile phone and panel computer are substantially all to access to your password to carry out authentication at present.Traditional fingerprint collecting equipment is used the interfaces such as USB or COM basically, these interfaces are widely adopted on PC, but for smart mobile phone and panel computer, interface common on PC does not exist usually, thereby limited the authentication strength that promotes smart mobile phone and panel computer by external fingerprint collecting equipment, its security can't be expanded.
Be that existing fingerprint collecting equipment can't carry out widespread use in smart mobile phone and panel computer.And smart mobile phone and panel computer also can't utilize the mode of finger print identifying to promote its security.
Can't use the problem of finger print identifying over against current smart mobile phone and panel computer, the present invention proposes the fingerprint acquisition instrument based on smart mobile phone and panel computer audio interface.Because audio interface extensively is present in smart mobile phone and panel computer, utilize audio interface to carry out the transmission fingerprint image information, thereby make smart mobile phone and panel computer can utilize fingerprint collecting equipment to carry out authentication.
The present invention includes following steps:
1) image fingerprint collecting chip collected is encoded
2) use analog-digital chip to convert digital signal to simulating signal the data after coding
3) by audio input interface, simulating signal is sent to smart mobile phone and panel computer
4) analog-digital chip that analog passband signal smart mobile phone and panel computer carry becomes digital signal by analog signal conversion
5) by supporting driving, digital signal decoding is generated to fingerprint image
The invention has the beneficial effects as follows:
Can be so that user's smart mobile phone and panel computer access fingerprint equipment easily, thus make smart mobile phone and panel computer can utilize fingerprint collecting equipment to carry out authentication, without memory cipher, promoted security and the convenience of authentication.The present invention is in a large number for field to higher grade of authentication.
The accompanying drawing explanation:
Fig. 1: data flow figure
Specific implementation method:
Shown in Fig. 1, below tell about implementation method of the present invention, comprise the following steps:
1) add coding chip, the image that the fingerprint collecting chip is collected is encoded
2) add analog-digital chip, convert the digital signal after coding to simulating signal
3) mode by recording is input to smart mobile phone and panel computer by simulating signal
4) analog-digital chip that analog passband signal smart mobile phone and panel computer carry becomes digital signal by analog signal conversion
5) by supporting driving, the digital signal software decode is generated to fingerprint image.
Claims (5)
1. the present invention has designed a kind of fingerprint acquisition instrument based on smart mobile phone and panel computer audio interface, its main method is encoded and is converted into simulating signal for the image that the fingerprint chip is produced, smart mobile phone and panel computer are transferred to finger print data in smart mobile phone and panel computer by the sound-recording function of audio interface, by for software and driving be reduced into fingerprint image, offer finger print identifying software.This invention makes user's smart mobile phone and panel computer access easily fingerprint equipment, thereby makes smart mobile phone and panel computer can utilize fingerprint collecting equipment to carry out authentication, without memory cipher, has promoted security and the convenience of authentication.
According to claim 1 a kind of fingerprint acquisition instrument based on smart mobile phone and panel computer audio interface, it is characterized in that: by smart mobile phone and panel computer audio interface, carry out the transmission fingerprint image information.
3. a kind of fingerprint acquisition instrument based on smart mobile phone and panel computer audio interface according to claim 1, is characterized in that: utilize analog-digital chip that finger print data is converted to simulating signal.
4. a kind of fingerprint acquisition instrument based on smart mobile phone and panel computer audio interface according to claim 1, is characterized in that: use smart mobile phone and panel computer audio frequency will simulate model by the sound collection mode and convert digital signal to.
5. a kind of fingerprint acquisition instrument based on smart mobile phone and panel computer audio interface according to claim 1, is characterized in that: sound figure information is converted into to the fingerprint characteristic image.
