Embodiment 1

[0059] figure 1 It is a flowchart of a method for electronic data preservation in Embodiment 1 of the present invention, such as figure 1 As shown, a method of electronic data preservation, including:

[0060] S101: the client connects to the server and verifies the time, the client performs environmental security monitoring and starts a screen recording function.

[0061] Specifically, when using the client in the present invention, it is necessary to try to connect to the server first. After the connection is successful, check the local time of the client and the time of the server. It is necessary to keep the time of the client consistent with the time of the server. When the time is inconsistent with the time of the server, the server returns a warning message to the client, requiring the client to modify the local time. If the client does not modify, but continues to operate, all time is based on the time of the server, and the time of the server is passed through the ne...

Embodiment 2

[0078] figure 2 It is a flowchart of a method for electronic data preservation in Embodiment 1 of the present invention, such as figure 1 As shown, a method of electronic data preservation, including:

[0079] S201: The client connects to the server and verifies the time, and the client performs environmental security monitoring and starts a screen recording function.

[0080] Specifically, when using the client in the present invention, it is necessary to try to connect to the server first. After the connection is successful, check the local time of the client and the time of the server. It is necessary to keep the time of the client consistent with the time of the server. When the time is inconsistent with the time of the server, the server returns a warning message to the client, requiring the client to modify the local time. If the client does not modify, but continues to operate, all time is based on the time of the server, and the time of the server is passed through t...

Embodiment 3

[0108] image 3 It is a system for electronic data preservation in Embodiment 3 of this method, such as image 3 As shown, an electronic data preservation system includes: the client 310, the server 320 and the third-party storage mechanism 330 in any one of the present invention, wherein:

[0109] The client 310 is connected with the server 320, including:

[0110] A screen recording module 311, configured to record the screen;

[0111] The first encryption module 312 is used for data encryption and decryption;

[0112] A first transmission module 313, configured to transmit data;

[0113] The first storage module 314 is used for storing data;

[0114] Server 320, connected with client 310 and third-party storage mechanism 330, includes:

[0115] The second encryption module 321 is used to encrypt and decrypt data;

[0116] A security certificate processing module 322, configured to make a security certificate;

[0117] A second transmission module 323, configured to t...

Abstract

The invention discloses an electronic data preservation method and system. The method comprises the steps that a client carries out connection with a server, checks time, monitors environment securityand starts a screen recording function; the client obtains appointed to-be-preserved original data and generates an original digest of the original data; the client encrypts the original data and uploads related data to a server; and the server checks the received data, uploads hash values generated after encryption to a third party storage mechanism for storage, makes a preservation certificateand sends the preservation certificate to the client. Through application of the method and the system, the technical problem that in the prior art, the authenticity of electronic data cannot be verified is solved.

Description

technical field [0001] The present invention relates to the field of information security, and more specifically, to a method and system for electronic data preservation. Background technique [0002] With the development of science and technology, electronic equipment has become an inaccessible part of society. When people use electronic equipment, a large amount of electronic data will be generated. These electronic data can be used as electronic evidence and applied in legal related fields, but they are different from traditional The legal evidence mainly has the following characteristics: First, it is scientific and technological, that is, electronic data is produced with the development of science and technology, it is easy to transmit, store and extract, and can be used repeatedly without any impact on the electronic data itself. However, its preservation depends on certain electronic equipment and storage technology. When the electronic equipment used for storage is d...
