Problems solved by technology

[0004] A technical problem to be solved by the present invention is that when the electronic data evidence in the prior art ensures the integrity, the information of the electronic data evidence is only solidified in time, which cannot fully satisfy the authenticity, relevance, Therefore, a method and system for verifying the admissibility of electronic data evidence can be simultaneously verified in terms of forensics personnel, system users, integrity, time, and space of electronic data evidence

Embodiment 1

[0052] The flow chart of the admissibility verification method of electronic data evidence according to the present invention is as follows: figure 1 As shown, it includes the following steps:

[0053]Perform identity verification of system users and store them in the data verification set;

[0054] Extracting the biometric information of the forensics personnel and storing it in the data verification set;

[0055] Obtain electronic data evidence files;

[0056] generating a digital abstract of the electronic data evidence file according to the electronic data evidence file, and storing it in a data verification set;

[0057] Obtain the timestamp and store it in the data verification set;

[0058] Obtain geographic location data and store it in the data verification set;

[0059] Simultaneously, the obtained result of the identity verification of the forensics personnel, the result of the identity verification of the system user, the digital summary, the time stamp and the...

Embodiment 2

[0097] Based on the same inventive concept, the present invention also provides an electronic data evidence admissibility verification system of electronic data evidence, such as figure 2 Its system structure diagram is shown, including the following modules:

[0098] The first verification module performs identity verification of system users and stores them in the data verification set;

[0099] The second verification module is used to verify the identity of the forensics personnel and store it in the data verification set;

[0100] The first acquisition module acquires electronic data evidence files;

[0101] A generation module, generating a digital abstract of the electronic data evidence file for the electronic data evidence file, and storing it in the data verification set;

[0102] The second acquisition module acquires the time stamp of the electronic data evidence file and stores it in the data verification set;

[0103] The third acquisition module acquires the...

Abstract

The invention relates to a verification method and system for adoptability of electronic data evidence. The method includes: authenticating a forensics subject and a system user, embedding authentication results and data such as digital digest, timestamp and geographic location into a QR code through a QR code generating program, displaying the results and data in a generated authentication report, comparing the information recognized through the QR code to corresponding information collected by data verification during authentication to determine whether the information is consistent to the corresponding information or not; if yes, determining that identity of the forensics subject is correct and that the electronic data evidence remains not tampered; if not, determining that identity of the forensics subject is not correct or that the electronic data evidence remains tampered. The completeness of the electronic data evidence is proved by extracting the digital digest from the electronic data evidence; legality of the forensics subject is guaranteed through authentication and verification over the forensics subject; adoptability of the electronic data evidence is guaranteed in terms of both time and space by adding the timestamp and geographic location data information.

Description

technical field [0001] The invention relates to the technical field of computer information processing, in particular to a method and system for verifying the admissibility of electronic data evidence. Background technique [0002] Electronic data evidence is stored in computer memory or external storage media in digital form, and can prove the number or information of the real situation of the case. Electronic data evidence usually has the characteristics of intangibility, diversity, destructibility, falsification, modification, storage and repeatability. Electronic data evidence in the computer is essentially a bunch of binary codes that are processed into "0" and "1" according to the coding rules, invisible and intangible. , audio, video and other multimedia forms are the embodiment of the development of modern science and technology in litigation evidence. In the judicial field, electronic data evidence has to be accepted as an effective evidence, and it must also meet...
