A cybersecurity researcher browsing an unsecured Chinese police web dashboard found something he did not expect: a comprehensive database of nearly every foreign journalist based in Beijing around 2021, complete with passport photos, private cellphone numbers, visa details, and dates of birth. Among the entries was his own. The discovery, reported to DW by the researcher known by the pseudonym NetAskari, offers one of the most detailed public glimpses yet into the architecture of China's state surveillance apparatus - and its specific targeting of foreign press.
What the Dashboard Actually Contained
The panel was a demonstration version of a remote tracking system designed for the Public Security Bureau in Zhangjiakou, the Hebei province city that hosted the 2022 Winter Olympics. Though built as a test environment, it was populated with real data - a detail that reveals something important about how these systems are developed and deployed: live personal information is routinely used even at the prototype stage.
The granularity of the data went far beyond what traditional CCTV surveillance could produce. The system logged the specific train carriage and seat number a tracked individual occupied when traveling from Beijing or Shanghai. Facial-recognition gates at local ski resorts fed photographs directly into the tracking mechanism. The movements of the researcher's acquaintances who had recently skied in Zhangjiakou were precisely mapped with detailed trajectories. Beyond physical movement, the system recorded gasoline consumption, regular shopping locations, and whether a person visited areas designated for public petitions - a category of behavior Chinese authorities treat as a political risk indicator.
The underlying concept has a name within China's security bureaucracy: the "holistic personnel archive," or what officials sometimes describe as a "holographic profile." The goal is to stitch together physical whereabouts, consumption patterns, and digital footprints into a single, continuously updated record. "The idea is simply to process as much data as possible from as many sensors as possible in real time," NetAskari noted.
Foreign Journalists Under Algorithmic Watch
Within this system, foreign nationals - and particularly journalists - occupy a distinct category. The dashboard's statistical summaries showed that Chinese security agencies disproportionately focus on citizens from the "Five Eyes" countries: the United States, the United Kingdom, Australia, New Zealand, and Canada. Certain foreign journalists were assigned a real-time tracking designation labeled "trackable," which automatically triggers early warnings the moment they enter a jurisdiction.
The practical consequences for reporting are severe. In the past, foreign correspondents traveling to sensitive regions such as Xinjiang could at least attempt to detect and evade plainclothes surveillance. That option is rapidly disappearing. Because the system has access to mobile payment records, transportation ticket purchases, and social network data, authorities can anticipate a journalist's itinerary before they arrive. If the data network detects contact between a journalist and a potential source, police can intervene with that source quietly, through phone calls or direct intimidation, without ever appearing in the journalist's field of view. The source is warned off before the interview takes place.
"They don't need to send two or three cars to follow you anymore," NetAskari said. The surveillance infrastructure has made physical tailing largely redundant.
Relationship Mapping and Predictive Policing
The most structurally significant feature of the system is not the individual tracking - it is the group analysis. The dashboard automatically generates network graphs based on how frequently individuals appear together in camera footage, mapping interpersonal relationships, estimating the strength of those connections, and visualizing who spends time with whom. This shifts the surveillance model from reactive to predictive: authorities do not need to witness a conversation to infer that it occurred.
This technology has been in development across multiple Chinese institutions for years. In 2019, the electronics company Hisense filed a patent for what it called "holistic relationship models for people involved in cases," designed to integrate travel records, call data, and vehicle usage. In 2025, the Shanghai Putuo Public Security Bureau awarded a contract worth approximately $200,000 for a "Holistic Personnel Archive System." These are not isolated experiments - they represent a consistent, publicly documented institutional investment in fusing data streams into a single behavioral prediction engine.
The broader infrastructure supporting this effort is China's Xueliang, or "Bright Eyes," initiative, which aims to connect the country's vast but fragmented network of street cameras into a unified national surveillance grid. What the Zhangjiakou dashboard demonstrates is that Xueliang is no longer the ceiling of ambition - it is the foundation on which a far more comprehensive system is being built.
Authoritarian Surveillance Versus Democratic Oversight
Western democracies are not without their own surveillance controversies. Platforms and data brokers accumulate personal information at scale, and tools built for national security have repeatedly been deployed in ways that civil liberties advocates have challenged in courts and legislatures. The comparison, however, has clear limits. In democratic systems, oversight mechanisms - however imperfect - exist: judicial review, freedom of information laws, parliamentary scrutiny, and independent journalism itself. In China, as NetAskari observed, "the police and the Ministry of State Security just do whatever they want with relatively little oversight."
The distinction is structural. What the Zhangjiakou dashboard represents is not an excess or an abuse of a system designed with constraints - it is the system functioning precisely as designed. Every tourist who skis at a Zhangjiakou resort, every commuter who boards a train, every journalist who files a story from Beijing dissolves, in NetAskari's framing, into what he calls a "datamass" - a collection of numbers, movement vectors, and behavioral patterns that can be monitored, shaped, and coerced as needed. The exposure of this dashboard did not reveal a malfunction. It revealed the machinery working as intended.
