Reliability verification method, device and system based on computer forensics

Abstract

The invention discloses a reliability verification method, a device and a system based on computer forensics. The method comprises the steps of obtaining hidden computer viruses, an image recognition model and a coding rule; enabling visible light to irradiate a real picture frame; performing first image acquisition processing to obtain a first image, and obtaining a first image recognition result; performing first encoding processing to obtain a first code; enabling ultraviolet rays and visible light to irradiate the real picture frame at the same time; performing second image acquisition processing to obtain a second image, and obtaining a second image recognition result; obtaining a second code; enabling the real picture frame to be only irradiated by ultraviolet rays; performing third image acquisition processing to obtain a third image, and obtaining a third image recognition result; performing third encoding processing to obtain a third code; integrating into a total code, and calculating a similarity value; and if the similarity value is greater than the similarity threshold, judging that the computer evidence obtaining is reliable. Therefore, the reliability verification of evidence obtaining of the 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...
