A reliability verification method, device and system based on computer forensics

Abstract

This application discloses a reliability verification method, device and system for computer forensics, which obtains hidden computer viruses, image recognition models and coding rules; irradiates visible light on the real picture frame; conducts the first image collection and processing, and obtains the second One image, to obtain the first image recognition result; carry out the first encoding process to obtain the first code; irradiate the ultraviolet light and visible light on the real picture frame at the same time; carry out the second image acquisition process to obtain the second image, and obtain the second Image recognition result; obtain the second code; make the real picture frame only be irradiated by ultraviolet rays; perform the third image acquisition process to obtain the third image and obtain the third image recognition result; perform the third encoding process to obtain the third code; Integrate into the total code, and calculate the similarity value; if the similarity value is greater than the similarity threshold, it is determined that the computer forensics is reliable. Therefore, the reliability verification of forensics for hidden computer viruses is realized.

Description

technical field [0001] This application relates to the field of computers, in particular to a reliability verification method, device and system for computer forensics. Background technique [0002] Computer forensics refers to the use of computer identification and analysis technology to distinguish the contents of the records generated during the operation of the computer system to prove the facts of the case. It can be applied to the forensics of computer viruses, and it also needs to be able to verify the reliability. However, traditional computer forensics and reliability verification schemes for computer forensics can only deal with overt computer viruses, but cannot complete the detection of hidden computer viruses (hidden computer viruses refer to the codes of computer viruses that are not directly stored in the computer). , but the reliability verification of forensics such as hidden in the real space). Contents of the invention [0003] This application propose...
