Abstract
The utility model discloses a two fingerprint authentication terminals, terminal hardware structure includes STM32 main control unit, two fingerprint identification modules, power conversion module, serial communication module and network communication module, wherein: the STM32 main controller respectively carries out information interaction with the fingerprint identification module through the serial port communication module, carries out relevance comparison with two piece of fingerprints gathered to carry out communication verification through network communication module and backstage. The utility model discloses a thereby match the fingerprint of operating personnel and supervisor both sides and realize carrying out the mandate of key operation to operating personnel, can effectively avoid the loss of bank property because of individual reason causes.
Description
Technical field
This utility model relates to embedded intelligence applied technical field, is specifically related to a kind of double fingerprint authentication terminal, utilizes the one of the fingerprint matching degree of fingerprint recognition calculating both sides to pick terminal.
Background technology
Fingerprint recognition be the feature utilizing fingerprint uniqueness and stability to realize identification, and fingerprint is remembered without user, and is easy to carry, so fingerprint is more and more applied to overcome deficiency and the inconvenience of traditional identity authentication mode；Additionally, fingerprint refers to the rough lines of finger surface skin, it is made up of multiple ridge shape figure, is in actual range when contacting with touch flat board at concave point with salient point different, thus the capacitance values produced also differs.
Recently, due to the deficiency in terms of banking supervision or control of authority, again and again disappeared suddenly event by the deposit exposed in depositor's bank card, cause numerous depositors to worry, and cause the highest attention of supervision layer.Due to the individual reason of some employee, other people deposit is diverted to other purpose or takeed forcible possession of, not only result in the property loss of user, cause economic loss and prestige crisis also to bank's aspect.The behavior such as transfer accounts how supervising bank employee becomes current problem demanding prompt solution.
Utility model content
The technical problems to be solved in the utility model is: for problem above, this utility model provides a kind of double fingerprint authentication terminal, this terminal is by matching operation people and the fingerprint of superintendent both sides thus realizes carrying out operator the mandate of key operation, can be prevented effectively from the bank's property loss caused because of individual's reason.
The technical scheme that this utility model is used is:
A kind of double fingerprint authentication terminal, described terminal hardware structure includes STM32 master controller, two fingerprint identification modules, power transfer module, serial communication modular and network communication module, wherein: it is mutual that STM32 master controller carries out information by serial communication modular and fingerprint identification module respectively, two pieces of fingerprint the being associated property comparisons that will collect, and communicate checking by network communication module and backstage.
Firstly the need of setting up operator and custodial fingerprint corresponding relation before certification, i.e. it is simultaneously entered the fingerprint of both sides, this corresponding relation can be automatically saved after system identification to background server.
Described terminal supports the fingerprint corresponding relation of a superintendent and multiple operators.
Described fingerprint identification module uses capacitance pressure transducer.
Comparing other pressure transducer manufacturers traditional pressure resistance type (PRT) absolute pressure transducer, capacitance pressure transducer can provide higher precision, lower power consumption, more preferable stability and concordance and be operated in the superior ability under extreme temperature, humidity environment.
The beneficial effects of the utility model are:
This utility model is by matching operation people and the fingerprint of superintendent both sides thus realizes carrying out operator the mandate of key operation, can be prevented effectively from the bank's property loss caused because of individual's reason.

Fig. 2 is certification terminal works flow chart.
Detailed description of the invention
Below by Figure of description, in conjunction with detailed description of the invention, this utility model is further illustrated:
Embodiment 1:
As shown in Figure 1, a kind of double fingerprint authentication terminal, described terminal hardware structure includes STM32 master controller, two fingerprint identification modules, power transfer module, serial communication modular and network communication module, wherein: it is mutual that STM32 master controller carries out information by serial communication modular and fingerprint identification module respectively, two pieces of fingerprint the being associated property comparisons that will collect, and communicate checking by network communication module and backstage.
Firstly the need of setting up operator and custodial fingerprint corresponding relation before certification, i.e. it is simultaneously entered the fingerprint of both sides, this corresponding relation can be automatically saved after system identification to background server.
Embodiment 2:
On the basis of embodiment 1, terminal described in the present embodiment supports the fingerprint corresponding relation of a superintendent and multiple operators.
Embodiment 3:
On the basis of embodiment 1 or 2, fingerprint identification module described in the present embodiment uses capacitance pressure transducer.
Comparing other pressure transducer manufacturers traditional pressure resistance type (PRT) absolute pressure transducer, capacitance pressure transducer can provide higher precision, lower power consumption, more preferable stability and concordance and be operated in the superior ability under extreme temperature, humidity environment.
Embodiment 4:
As in figure 2 it is shown, on the basis of embodiment 3, the present embodiment concrete operation step is as follows:
(1) arranging terminal operating mode is to gather information pattern, is then simultaneously entered superintendent and operator's fingerprint, can continue superintendent and the fingerprint of other operator according to prompting or complete to operate after having inputted；
(2), after system acquisition completes, the fingerprint corresponding relation of superintendent and operator is preserved and backs up to background server by terminal automatically；
(3) when bank's related system need to carry out key operation certification, the fingerprint of superintendent and operator need to be simultaneously entered terminal, system carries out conscientiously automatically, and after certification is passed through, system authorization operates, and otherwise, system cannot be carried out operating further.
Embodiment of above is merely to illustrate this utility model; and be not limitation of the utility model; those of ordinary skill about technical field; in the case of without departing from spirit and scope of the present utility model; can also make a variety of changes and modification; the technical scheme of the most all equivalents falls within category of the present utility model, and scope of patent protection of the present utility model should be defined by the claims.
Claims (3)
1. a double fingerprint authentication terminal, it is characterized in that: described terminal hardware structure includes STM32 master controller, two fingerprint identification modules, power transfer module, serial communication modular and network communication module, wherein: it is mutual that STM32 master controller carries out information by serial communication modular and fingerprint identification module respectively, two pieces of fingerprint the being associated property comparisons that will collect, and communicate checking by network communication module and backstage.
