Security system based on fingerprint identification

Abstract

In order to improve the identification accuracy of real human body characteristic parameters and improve the identification security of access control units, the present invention provides a security system based on fingerprint identification, which is used for fingerprint identification of access control units with identification sensors and loudspeakers, including local, The remote two parts carry out identification and comprehensive judgment respectively. For the false medium to be identified, it will give an unrecognizable prompt, and for the real medium that can be identified, it will give a prompt of recognition success or failure. During the identification process, the temperature of the access control unit itself is The influence of the zero drift generated by the identification sensor during the heating process was not eliminated, but it was actively considered and compared with the empirical calculation method of square root calculation in the calculation of the two test results, so that in the analysis and calculation It is ignored in the calculation of v, that is, it is eliminated in the calculation of the square root when calculating v. After testing, the recognition accuracy of false objects to be recognized has increased by about 43%.

Description

technical field [0001] The invention belongs to the technical field of security and image processing, and in particular relates to a security system based on fingerprint identification. Background technique [0002] Biometrics is a new identity authentication technology. In real life, everyone has unique biological characteristics that are different from other people. With the development of computer technology, people can extract their own biometric information, such as face, fingerprint, finger vein, iris, voiceprint, etc. This technology that relies on people's physical characteristics for identification is called biometric technology. [0003] Recently, due to the development of smart phones and various mobile and wearable devices, the importance of technologies for security authentication is increasing. Among this form of technology, fingerprint recognition technology is widely used due to its high degree of convenience, security and economic feasibility. In general...

Problems solved by technology

Therefore, only using single biometrics (single-mode biometrics) to identify identity is easy to be forged and deceived, such as a single fingerprint picture is easy to be forged, easy to imitate and steal, and fingerprint identification was originally used in the criminal field to make some Users have resistance, and some users cannot collect effective and clear images with a single fingerprint (finger vein, etc.), which makes the single-mode biometric system have certain limitations in practical applications.
