The invention discloses an electronic data evidence obtaining method and a system. The method comprises the steps that a plurality of channels of evidence obtaining equipment are connected with a host one by one, interface mark information corresponding to a conversion module of each channel is obtained, and the interface mark information is written into the corresponding interface conversion module; connecting any one of the plurality of channels with the host, initializing the historical setting information of the current channel, writing the interface mark information into a boot sector of a disk of the current channel, and setting the current channel as a main channel; copying the evidence obtaining application to a disk space of the main channel, connecting the plurality of channels with a host, and opening and running the evidence obtaining application after the host identifies the plurality of channels; the evidence obtaining application divides the data of the host into a plurality of mirror image files, and meanwhile the mirror image files are stored in the channels. The device is portable and convenient, and can be used for effectively solving the problems of small data storage space and low speed of evidence obtaining equipment when a specific department performs data collection on a target computer.
Description
technical field [0001] The invention relates to the technical field of electronic data forensics, in particular to a method and system for electronic data forensics. Background technique [0002] With the rapid development of Internet technology and computer technology, crimes involving computers are also expanding, so the technical application of electronic data forensics is also constantly updated, such as portable electronic data forensics equipment, laboratory-specific fixed forensics equipment, etc. [0003] In the field of electronic data forensics, hard disk data acquisition is an important means of on-site investigation. However, with the growth of hard disk capacity and storage data of the host computer for forensics, it takes a long time to obtain evidence and requires a large storage space. High requirements, and portable forensics equipment is often small in size, the capacity of its own storage space is not large, and the speed of forensics is relatively not fas...
