非接触式移动信息取证系统刑侦与司法鉴定应用介绍
非接触式移动信息取证系统,是专为刑事侦查与犯罪现场勘查打造的电子信息被动采集核心装备,也是案件初期侦查方向划定、嫌疑人轨迹分析、涉案人员摸排的关键刑事技术装备,将物理空间侦查延伸至电子信号空间,为案件侦破提供核心时空与电子关联线索。
系统基于蜂窝移动通信与无线局域网协议无感侦测原理,通过专用射频模块与合规信令交互,在不接触目标终端、不干扰正常通信、不读取用户个人数据、目标全程无感知的前提下,快速采集覆盖范围内活跃移动终端的唯一电子身份标识。设备支持车载移动部署,可实现动态场景下涉案区域电子信息 “快照式” 筛查,解决了传统侦查线索摸排效率低、隐蔽性差、动态场景适配难的行业痛点。
在刑侦实战中,系统核心应用覆盖四大领域:一是犯罪现场外围电子痕迹固定,快速采集案发时段现场周边的终端电子标识,精准划定涉案人员排查范围;二是嫌疑人轨迹分析与串并案侦查,勾勒嫌疑终端活动规律,通过多案发现场数据比对为系列案件串并提供关键线索;三是大型活动安保与要人护卫,监测异常电子信号聚集,实现风险前置预警;四是涉恐涉稳案件隐蔽侦查,辅助监控可疑人员活动关联。
实战应用案例:1. 某重大凶杀案,案发后侦查人员在核心现场及周边快速部署设备,采集案发时段前后的终端电子标识,通过时空碰撞锁定可疑信号,结合视频监控线索 24 小时内锁定嫌疑人;2. 某系列沿街商铺盗窃案,通过 12 个案发现场采集的电子标识数据库比对,找到全场景重复出现的可疑终端信号,成功串并 15 起案件,快速打掉流窜作案团伙。
本系统为刑事侦查提供了全新的情报获取维度,大幅提升了线索摸排效率与侦查行动隐蔽性,是各级公安刑侦、反恐、安保部门应对新型犯罪挑战的核心技术装备。
Application Introduction of the Non-Contact Mobile Information Forensic System in Criminal Investigation and Forensic Identification
The Non-Contact Mobile Information Forensic System is core passive electronic information acquisition equipment specially developed for criminal investigation and crime scene investigation. It is also key criminal technical equipment for defining investigation direction in the initial stage of cases, analyzing suspect activity tracks, and investigating the relationship of involved persons. It extends investigation from physical space to electronic signal space, providing core spatio-temporal and electronic correlation clues for case detection.
Based on the non-intrusive passive detection principle of cellular mobile communication and Wi-Fi protocol, through dedicated radio frequency modules and compliant signaling interaction, the system can quickly acquire unique electronic identity identifiers of active mobile terminals within the coverage, without physical contact with target devices, interference with normal communication, access to user personal data, or any perception of the target user. It supports vehicle-mounted mobile deployment, and can realize "snapshot" screening of electronic information in the involved area under dynamic scenarios, addressing the industry pain points of conventional investigation, such as low clue investigation efficiency, poor concealment, and weak adaptability to dynamic scenarios.
In the practical operation of criminal investigation, the core applications of the system cover four major areas:
- Fixation of electronic traces around crime scenes, to quickly acquire terminal electronic identifiers around the scene during the crime period, and accurately define the investigation scope of involved persons;
- Suspect track analysis and serial case linkage investigation, to outline the activity rules of suspect terminals, and provide key clues for serial case linkage through data comparison across multiple crime scenes;
- Large-scale event security and VIP protection, to monitor abnormal aggregation of electronic signals and realize proactive risk early warning;
- Covert investigation of terrorism and social stability-related cases, to assist in monitoring the activity correlation of suspicious persons.
Practical Forensic Application Cases:
- In a major homicide case, investigators quickly deployed the equipment in and around the core crime scene after the incident, acquired terminal electronic identifiers before and after the crime period, locked suspicious signals through spatio-temporal collision analysis, and identified the suspect within 24 hours combined with video surveillance clues.
- In a serial theft case targeting street-side shops, through comparison of electronic identifier databases collected from 12 crime scenes, the system found suspicious terminal signals that appeared repeatedly in all scenes, successfully linked 15 cases, and quickly took down the itinerant criminal gang.
This system provides a brand-new intelligence acquisition dimension for criminal investigation, greatly improves the efficiency of clue investigation and the concealment of investigation operations, and serves as core technical equipment for criminal investigation, counter-terrorism and security departments of public security authorities at all levels to respond to the challenges of new types of crimes.
