Embodiment Construction

[0041] The present invention is described in further detail now in conjunction with accompanying drawing.

[0042] figure 1 A structural diagram of the trusted model is described. In the present invention, the trustworthy model of digital survey record is recorded as T, T=(E, A, DR, TR, Sign), where E is the entity in the model, E={S, C i}, S is the server, C i For the currently surveyed terminal equipment, S and C i They are connected through a wireless communication network; A is the set of cryptographic algorithms in the model; DR is the set of all digital survey records, DR={dr i |dr i ∈ {digital photo, digital transcript, video, audio}}; TR is a collection of credible digital survey records, TR={Sign(dr i )}; Sign is credible operation; DT is date and time; GPS is C i The current geographic coordinates of .

[0043] The process of using this system for trusted operations is as follows:

Abstract

The invention discloses a digital on-site survey record credible model system and a method for using the system to perform credible operation. The system records the digital on-site survey record credible model as T, and T=(E, A, DR, TR ,Sign), TR is a set of credible digital survey records, TR={tr i |tr i =dr i +Sign(dr i )}, Sign is a credible operation. If the data recorded above is tampered with, the verification will fail, and the credible survey data tr n can be verified. The present invention aims at the digital records generated in the investigation of the crime scene, and performs credible processing on them to generate a credible digital record of the current survey. The credibility of the record is shown in anti-tampering and non-repudiation, because the terminal is Dedicated, the digital signature guarantees which terminal the data is collected from, so the terminal holder cannot deny it. It not only effectively solves the technical problem that the photos and videos taken by the existing mobile terminal are easily tampered with, but also solves how to make up the signature and signature issues.

Description

technical field [0001] The invention belongs to the technical field of protecting data integrity in digital data processing, and in particular relates to a method for credible operation using a digital survey record credible model system. Background technique [0002] With the advancement of science and technology, the police work of the public security department has also entered the digital age. Crime scene investigation usually refers to the on-site inspection of people and things related to the crime, as well as places, objects, people, and corpses, etc. Visits, inspections, and crime scene investigations must be carried out in specific spatial domains by using criminal science and technology in accordance with national laws and regulations. On-site survey records are a collection of documents and attachments formed after the on-site survey work, mainly including: on-site transcripts, on-site photos, on-site videos, on-site audio, traces, various physical evidence, vari...
