Verification method and system for adoptability of electronic data evidence

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...

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
