Abstract
The utility model discloses a fingerprint identity authentication and signature semiconductor device of a police mobile law enforcement terminal. The device comprises a fingerprint sensor, a fingerprint decoding chip, an ARM A8 chip, and a power supply circuit, wherein the fingerprint sensor is mounted on an outer shell of the police mobile law enforcement terminal; the fingerprint sensor is connected with the fingerprint decoding chip through an FPC; and the fingerprint decoding chip is connected with the ARM A8 chip through a USB or an IIC. According to the fingerprint identity authentication and signature semiconductor device, the fingerprint decoding chip is connected with the ARM A8 chip through the USB or the IIC, and excellent algorithms are utilized for identification or encrypted storage of fingerprints. The fingerprint identity authentication and signature semiconductor device not only effectively prevents the police mobile law enforcement terminal from being used by illegal users and guarantees the specificity of the utilization of the police mobile law enforcement terminal, but also improves the convenience of the utilization of the police mobile law enforcement terminal and ensures the integrity of law enforcement evidences.
Description
Technical field
The utility model relates to a kind of alert semiconductor device with mobile law enforcement terminal fingerprint identity validation and electronic signature that has, and especially is applicable to specificity and on-the-spot traffic police industry of signing that equipment is used.
Background technology
At present, enforcement along with " Golden Shield " engineering, whole nation traffic police has disposed a large amount of alert mobile law enforcement terminals of using, alert do not have the semiconductor fingerprint module basically with the mobile law enforcement terminal device, for the very strong alert mobile law enforcement terminal of using of specificity, the alert mobile law enforcement terminal of use of anyone operation of can starting shooting, alert with the mobile law enforcement terminal in case loss, the security of data is brought very big hidden danger.Simultaneously, one line traffic police is in process on duty, by the alert penalty note of leaving with the mobile law enforcement terminal, can only pass through manual signature, and signature contents can not upload to the service end infosystem as the evidence of on-site law-enforcing, namely uploads to the effective policeman's signature on duty of poor information of service end and the law enforcement evidence of penalized person's signature.Though the papery penalty note of opening at present all bears the signature, use heat-sensitive paper as material because of papery, to meet high temperature or under natural light, preserve, the evidence that is very easy to cause enforcing the law is lost.In addition, when the policeman uses mobile law enforcement end message system in the login police, in order to improve security, password all adopts high-intensity mixed characters, people institute is known, and it is convenient that alert input with the mobile law enforcement terminal is far from computer, the serious like this speed that restricts login system.
Summary of the invention
The utility model is in order to overcome the shortcoming that prior art exists, and the utility model provides a kind of alert semiconductor device with mobile law enforcement terminal fingerprint identity validation, signature that has.
The utility model discloses a kind of alert with mobile law enforcement terminal fingerprint identity validation signature semiconductor device, comprise fingerprint sensor, fingerprint decoding chip, ARM A8 chip, power circuit, described fingerprint sensor is installed in alert with on the mobile law enforcement terminal enclosure, fingerprint sensor is connected with the fingerprint decoding chip by FPC, and the fingerprint decoding chip is connected with ARM A8 chip by USB or IIC.The utility model utilizes USB, IIC to be connected with the fingerprint decoding circuit, adopts excellent algorithm that fingerprint is carried out identification or encrypts storage.
The technical scheme that the utility model technical solution problem adopts is: with the shell of mobile law enforcement terminal fingerprint sensor is installed alert, namely touch fingerprint and finish gatherer process in the fingerprint collecting district.Fingerprint sensor utilizes active capacitance imaging technology, according to particular community and the external environment pointed fingerprint image is optimized, and eliminates ground unrest to greatest extent, improves signal to noise ratio (S/N ratio), forms the image an of the best.Fingerprint sensor is connected with the fingerprint decoding chip by FPC (flexible PCB), and the fingerprint image of fingerprint decoding chip to gathering carries out identification or encrypt storage it in conjunction with excellent algorithm.The fingerprint decoding chip is connected with ARM A8 chip by USB or IIC (internal integrate circuit bus).When needing identification and access fingerprint image, ARM A8 powers on for the fingerprint decoding chip by power circuit earlier, sends instruction to the fingerprint decoding chip then, finishes corresponding action.
The beneficial effects of the utility model are, have both prevented effectively that the disabled user from using equipment, guarantee the specificity that equipment uses, and have improved the convenience of using again, and have guaranteed the integrality of law enforcement evidence.

Fig. 2 is the side exploded view of the utility model fingerprint sensor.
Fig. 3 is the front structural map of the utility model fingerprint sensor.
Fig. 4 is structured flowchart of the present utility model.
Among the figure: fingerprint sensor 1, fingerprint decoding chip 2, ARM A8 chip 3, power circuit 4, FPC5, IIC6.
Embodiment
Fig. 1-Fig. 4 shows most preferred embodiment of the present utility model, and the utility model is installed fingerprint sensor 1 at alert shell with the mobile law enforcement terminal, and namely touch fingerprint and finishes gatherer process in the fingerprint collecting district.Fingerprint sensor 1 utilizes active capacitance imaging technology, according to particular community and the external environment pointed fingerprint image is optimized, and eliminates ground unrest to greatest extent, improves signal to noise ratio (S/N ratio), forms the image an of the best.Fingerprint sensor 1 is connected with fingerprint decoding chip 2 by FPC5 (flexible PCB), and the fingerprint image of 2 pairs of collections of fingerprint decoding chip carries out identification or encrypts storage it in conjunction with excellent algorithm.Fingerprint decoding chip 2 is connected with ARM A8 chip 3 by IIC6 (internal integrate circuit bus).When needing identification and access fingerprint image, ARM A8 powers on for fingerprint decoding chip 2 by power circuit 4 earlier, sends instruction to fingerprint decoding chip 2 then, finishes corresponding action.
