Embodiment Construction

[0045] figure 1 Provided is the system for analyzing and extracting digital evidence described in the present invention, from figure 1 It can be seen from the figure that the system for analyzing and extracting digital evidence described in the present invention includes three functional layers, and each layer includes multiple functional modules. The three functional layers are the evidence protection layer, the evidence analysis layer, and the evidence presentation layer. The evidence protection layer includes the virtual hard disk module, the hash signature module, and the access control module. The evidence analysis layer includes the evidence analysis engine, and the evidence presentation layer includes local analysis. module and remote analysis module.

[0046] Such as figure 1 As shown, the function of the evidence protection layer is to protect the evidence before analyzing it, and prevent the evidence from being modified or destroyed during the process of analyzing ...

Abstract

A pick and analysis system can be used to choose and analyze figure proof. The proof protecting layer of it protects the analyze proof and prevent to amend and destroy the proof when analyzing and picking. The proof analytic layer of it picks and analyzes the figure proof comprised by the pick and analysis object. The proof expression layer of it offers operation interface for the user's inquiry and consult, and pick and analyze the figure proof of the pick and analysis object. It identifies collects and analyzes figure proof without any destroy, and then protects effectively the dependability and creditability of the figure proof in the system. The system and method prove the originality character of the figure proof and get dependability analysis conclusion.

Description

technical field [0001] The invention relates to a dedicated system and method for analyzing and extracting digital evidence existing in computers and related peripherals. The invention can analyze and extract a large number of digital evidences, and the analyzed and extracted digital evidences have sufficient reliability, can meet the elements stipulated by law, and are accepted by courts. Background technique [0002] With the continuous development of information technology, computers are more and more involved in people's work and life, and computer-related cases (such as e-commerce disputes, computer crimes, etc.) are also emerging. [0003] According to the survey and expert estimates of the American AB Federation, the economic loss caused by computer crimes in the United States is as high as 15 billion US dollars every year. According to a survey report released by the British police, in 2003, cyber crimes caused huge economic losses to large British companies. Accor...
