Ministry of Public Security and the National Police Data System
Connects identity administration, public order, criminal investigation, cybersecurity, borders, and public video systems.
Contents
Formal position
The MPS leads national policing, while local police handle public order, criminal investigation, cybersecurity, household registration, traffic, and borders. Multiple operational systems create extensive identity and behavior data.
Authority and tools
Tools include population and identity databases, police platforms, public video, cyber enforcement, device search, lodging and vehicle records, and cross-regional requests.
Interfaces with other bodies
Cyberspace regulators, telecoms, transport, hotels, platforms, and communities provide data or execution interfaces, while procuratorates and courts handle criminal cases.
Power logic
Police data systems turn dispersed registration into searchable relations and trajectories, extending policing from event investigation to risk screening and preemption.
Evidence limits
National laws and regulations provide some rules, but database linkage, alert models, access logs, and personal correction routes remain only partly public. [1] [2]
