Problems solved by technology

This makes electronic evidence extremely vulnerable to external damage in the process of storage, transmission and use, making it tampered beyond recognition or even disappear.
Therefore, electronic evidence is usually relatively fragile, and it is difficult to review and determine its authenticity in the process of being used as evidence

Embodiment 1

[0069] Embodiment 1 of the present invention provides an electronic evidence data transmission method, the process of which is as follows figure 1 shown, including the following steps:

[0070] Step S101: the evidence collection client obtains electronic evidence files.

[0071] The evidence collection client starts the evidence collection process according to the user's evidence collection instructions; according to the evidence collection method selected by the user, it uses screen recording or screenshots to obtain the electronic evidence files requested by the user.

[0072] Documents, pictures, audio and video, digital certificates, computer programs and other electronic files, information published on web platforms such as web pages, blogs, microblogs, circle of friends, post bars, and online disks, user registration information, identity authentication information, electronic transaction records, communications Records, login logs and other information, as well as comm...

Embodiment 2

[0123] Embodiment 2 of the present invention provides a specific implementation process of the electronic evidence data transmission method, the process of which is as follows Figure 4 shown, including the following steps:

[0124] Step S401: Start the evidence collection process.

[0125] The forensics client starts the forensics process after receiving the user's forensics instruction.

[0126] Step S402: Obtain electronic evidence files.

[0127] The forensics client collects electronic data according to the screen recording or screen capture method selected by the user, and at the same time collects the subject information, environmental information, process information, etc. that generate the electronic data, so as to realize the integrity of the electronic data and ensure the restoration of the environment and process of the electronic data generation With traceability, access to electronic evidence files.

[0128] Step S403: Divide into several small files.

[0129...

Abstract

The invention discloses an electronic evidence data transmission method, an electronic evidence data transmission system, and equipment. The method comprises the steps as follows: an evidence taking client acquires an electronic evidence file; the evidence taking client divides the acquired electronic evidence file into a plurality of small files, and determines a check value corresponding to eachsmall file and a check value of the electronic evidence file; the evidence taking client sends each small file and the corresponding check value and the check value of the electronic evidence file toan evidence taking server, so that the evidence taking server checks the small files according to the check values corresponding to the small files and checks the electronic evidence file according to the check value of the electronic evidence file. The correct transmission of the electronic evidence data can be ensured, the condition that the electronic evidence is not tampered is ensured, and the authenticity and reliability of the transmitted data are improved.

Description

technical field [0001] The present invention relates to the technical field of electronic evidence preservation, in particular to an electronic evidence data transmission method, system and device in the electronic evidence curing process. Background technique [0002] There are great differences between electronic evidence and traditional legal evidence in terms of presentation, preservation and security. Electronic evidence is a product of electronic technology, which relies on computer technology, network technology, storage technology and other technologies to exist, and can exist in the form of text images, pictures, sounds, pictures, etc. and spread on the network. Electronic evidence is essentially a bunch of "0"s and "1s" processed according to coding rules. These coded data exist on media media in the form of sound, light, electricity, and magnetism, and are invisible objects that cannot be directly viewed. Invisible and intangible, only through specific equipment ...
