Security implementation method of fingerprint module in alarm controller

Abstract

The invention particularly relates to a security implementation method of a fingerprint module in an alarm controller. The fingerprint module collects fingerprint information, extracts a fingerprint ID generated by a fingerprint feature code in the fingerprint information, and sends the extracted fingerprint ID and associated alarm host ID information to the alarm host at the same time. The alarmhost receives the fingerprint ID information and the alarm host ID information, judges whether the received fingerprint ID is matched with pre-stored fingerprint information or not, and if yes, determines that the fingerprint verification is successful. According to the method, the security level is improved through the method for fingerprint identification and host ID simultaneous identification,so that the problem that the problem of relatively low security due to the fact that fingerprint storage and fingerprint authentication are processed by the fingerprint module is avoided, and the security of the fingerprint identification is improved; and the method has relatively high usability and practicability. Due to the uniqueness of fingerprints of persons, only the designated persons canperform operation.

Description

technical field [0001] The invention relates to the field of security arming, in particular to a security implementation method of a fingerprint module in an alarm controller. Background technique [0002] At present, the arming and disarming of the alarm host on the market adopts a digital password, which can be changed through programming settings, and the alarm host is armed and disarmed by entering the password when in use. For banks with increasingly high security requirements, the security level of the fixed password mode is not high, and the password is easily forgotten, leaked, guessed, etc. Therefore, a more secure way is needed to change the security system using traditional password arming and disarming solutions, such as fingerprint recognition. However, the applicant found through research that, in the existing fingerprint authentication technology, both fingerprint storage and fingerprint authentication are handled by the fingerprint module. During fingerprin...

Problems solved by technology

During fingerprint comparison, the fingerprint module completes fingerprint collection and fingerprint comparison, and then returns the fingerprint comparison result to the host, which makes the host more vulnerable to attacks, for example, replace the fingerprint module with an illegal module, and then the illegal module feeds back the fingerprint comparison If the passed message is sent to the alarm host, the alarm host can be operated directly without fingerprint authentication, resulting in a decrease in the security of the entire alarm system.
