Physical evidence information preservation traceability monitoring system and monitoring method

Abstract

The invention discloses a physical evidence information preservation traceability monitoring system and monitoring method. According to the physical evidence information preservation traceability monitoring system, a physical evidence information/electronic evidence record supervision mechanism of a physical evidence information acquisition terminal, a material evidence identity authentication code mechanism and a personnel identity authentication code mechanism in which the material evidence information acquisition terminal and the material evidence information supervision server cooperate with each other better ensure the association record completeness and traceability among the material evidence information/electronic evidence preservation data, the material evidence/electronic evidence material object and the material evidence acquisition personnel; the physical evidence information preservation traceability monitoring method is helpful to assist in reducing the probability of physical evidence information/electronic evidence collection errors, and enhances the convenience of physical evidence information/electronic evidence preservation traceability; therefore, the probability of occurrence of events which adversely affect the promotion of cases and the crime determination and sentencing of criminal suspects due to loss of material evidences/electronic evidences can be reduced.

Description

technical field [0001] The invention relates to the technical field of evidence collection and preservation, and in particular to a traceability monitoring system and monitoring method for physical evidence information preservation. Background technique [0002] With the popularization of computer and network technology, electronic business activities and many other network-based interpersonal interactions have appeared in large numbers, and electronic files have become an important carrier for transmitting information and recording facts. Once a dispute or case occurs in these areas, the relevant electronic documents will become important evidence. Digital Evidence is the electronic data that is studied as evidence and can prove the relevant facts of the case. [0003] Electronic evidence is usually defined as: files generated based on electronic technology and stored in digital forms on various electronic equipment carriers such as disks, CDs, memory cards, mobile phones,...

Problems solved by technology

[0005] However, due to human error, the complex environment of the evidence collection site, etc., it is still easy to cause omissions in the collection of physical evidence information or preservation measures

For example, due to human error and other circumstances, after the obtained physical evidence is put into the physical evidence bag and sealed, the physical evidence information filled in the physical evidence bag is not complete, and the information of witnesses, holders, collectors, etc. are omitted, resulting in incomplete physical evidence information; and For example, there are many criminals at the evidence collection scene, so there are a large number of electronic evidence related to electronic evidence such as disks, CDs, memory cards, and mobile phones. Due to the evidence bag being wiped, polluted, damaged, etc., the information on the holder of the physical evidence recorded in it is blurred and it is difficult to confirm the corresponding holder; etc.

These situations are likely to make it difficult to effectively trace the source of physical evidence information due to incomplete records or omissions, so that it cannot be used as effective evidence. If such a situation occurs in important criminal evidence, it will affect the progress of the case and even the conviction and sentencing of the criminal suspect. have a significant adverse effect on
