Security Protection System Based on Behavior Fingerprint

Abstract

The invention discloses a security protection system based on a behavior fingerprint. The system comprises a collection module, a training module and a comparison module. The collection module is used for collecting behavior fingerprint information of a user and transmits the behavior fingerprint information to the training module. The training module models to obtain a judging threshold value of the behavior fingerprint information by employing a SVM. The comparison module receives new fingerprint information from the collection module and compares the fingerprint information with the judging threshold value, thereby identifying a user identity. According to the system, an attack behavior of an invader can be discovered in real time and can be blocked actively, the security and normal operation of a mobile terminal can be ensured, the security cost is reduced, the reservation cost of the user for a key is reduced, the risk of losing the key is reduced, and the system is operated along with the original protection system, thereby increasing a security protection measure. When the system is employed by the user, a whole process can be protected, the user does not need to remember any key, a hidden protection effect is realized, the system is taken as a second defense line for the security of the mobile terminal of the user, and the system has wide applicability.

Description

technical field [0001] The present invention relates to a technology in the field of equipment security, in particular to a security protection system based on behavioral fingerprints. Background technique [0002] A mobile terminal is a computer device used on the move, including mobile phones and other portable devices. With the development of technology, the mobile terminal has changed from a simple caller to a comprehensive information processing platform. The security of mobile terminals is becoming more and more important, and the passive defense measures usually adopted, such as passwords, lock screen patterns, etc., cannot effectively prevent intruders. Behavioral fingerprints refer to the characteristics of users that are different from others due to personal habits and biological differences in the operation of electronic equipment. Contents of the invention [0003] The present invention aims at defects such as only gyroscope sensors are used in the prior art,...

AI Technical Summary

Problems solved by technology

[0003] The present invention aims at defects such as only gyroscope sensors are used in the prior art, and single-dimensional data cannot effectively describe the behavior characteristics of users, and it has low accuracy, poor model reliability, and poor adaptability to different terminals, etc., and proposes a The security protection system based on behavioral fingerprints can detect and actively block intruders' attacks in real time, ensuring the security and normal operation of mobile terminals, reducing security costs, reducing the user's key storage costs and the risk of key loss , and run simultaneously with the original protection system as an added security measure
