Abstract

The invention discloses a random number generation method and system based on face image recognition, belongs to the field of an information security technology and aims to solve the technical problemof how to generate a random number of a mobile device on the premise of guaranteeing security and convenience. According to the method, whether a mobile device user is a mobile device owner or not isconfirmed by acquiring a face video of the mobile device user and performing face recognition, and a random number is generated by performing error calculation on the face video of the mobile deviceuser. The system comprises a user verification module, a random number generation module and a storage module, wherein the user verification module comprises a face collection unit, a video processingunit and a face recognition unit, and the random number generation module comprises an image processing unit and a HASH calculation unit. Through the random number generation method and system, a random and unpredictable random number can be generated, and loss caused by mobile device losing can be avoided.

Description

technical field [0001] The invention relates to the technical field of information security, in particular to a method and system for generating random numbers based on face image recognition. Background technique [0002] In the era of mobile Internet, mobile devices are becoming more and more popular, and the security requirements are getting higher and higher, so the participation of cryptographic algorithms is required to ensure the security of user equipment, but cryptographic algorithms depend on the security of random numbers, and the generation of random numbers is mainly Rely on hardware noise source devices such as encryption machines. In the existing random number generation scheme, since the client is inconvenient to use large-scale equipment, the client generates random numbers in a pseudo-random manner, and the server uses an encryption machine or random source hardware. Obviously, the method of collecting random numbers by the encryption machine is not suitab...
