Secure memory implementation method and system

Abstract

The invention discloses a secure memory implementation method and a secure memory implementation system, and the secure memory implementation system comprises a face algorithm and a secure memory service which are arranged at a secure execution environment end; a client program,camera service, a secure memory distributor and a secure memory arranged at a general execution environment end; and a camera hardware. The invention has the technical effects that the safe memory can be quickly allocated, and the dependence of a safe camera technology on hardware is reduced, so that the advantages brought by safe camera service can be used on a low-end device lacking hardware protection.

Description

technical field [0001] The present application relates to the field of computer technology, in particular to a method and system for implementing a secure memory. Background technique [0002] In recent years, the authentication mechanism of face recognition has become more and more popular, but it has also caused some security concerns. If the process of face recognition is interfered by malicious hackers and directly replaces the face data to be recognized, it may directly endanger the rights and interests of users. Therefore, it is extremely important to ensure the security of the face recognition process, and the security camera is a technology born out of this demand. The purpose of using the security camera is to ensure that during the process of face recognition, the face data will not be tampered with due to the security loopholes of some programs, so the security risks can be greatly reduced. [0003] Security cameras are usually equipped with a Trusted Execute En...

Problems solved by technology

But the number of continuous physical addresses is limited, the more the number, the higher the cost

Usually only higher-end devices have extra MPU for this function, and low-end devices have only enough MPU to isolate TEE memory, which makes it almost impossible for low-end devices to use secure memory technology

The security camera itself is also a proprietary technology of the chip supplier. In addition to the hardware cost, there is usually a software integration fee, which also raises the threshold for mid-to-high-end devices to use this technology.
