The invention relates to an electronic evidence fixing method, a terminal device and a storage medium. The method comprises the following steps of 1, compressing
data information and adding the compressed
data information to a buffer
queue A; 2, collecting data contents, adding the collected data contents to a buffer
queue B, encrypting and compressing the data contents in the buffer
queue B, andadding the encrypted and compressed data contents to the buffer queue A; 3, judging whether data blocks in the buffer sequence A meet
standardization requirements or not in real time; 4, constructingaddressing
list data in the buffer queue A, encrypting the addressing
list data, and adding the encrypted addressing
list data to an addressing list data region; 5,
copying the data blocks in the buffer sequence A to a
backup region of a
mirror image file; and 6, constructing a file control region in the
mirror image file. Through simplified structured design, network resources comprised in
computer software and hardware can be effectively and correctly fully utilized in the creation and usage processes of the evidence
mirror image file.
