A newly uncovered Chinese surveillance platform has revealed the extraordinary scale and sophistication of the country’s expanding monitoring system, showing how authorities can track individuals through everything from train seats to ski resort facial-recognition checkpoints.
The revelations came from a cybersecurity researcher using the pseudonym NetAskari, who discovered an unsecured Chinese police dashboard containing sensitive personal data belonging to foreign journalists based in Beijing around 2021.
The files included official passport photos taken by immigration authorities, phone numbers, visa information and birth dates. NetAskari also found his own personal details inside the database.
Speaking to Deutsche Welle, the researcher said the discovery was less shocking than revealing because journalists working in China already assume they are constantly monitored. What surprised him, he said, was how easily such highly sensitive information could be accessed.
The system appears to be part of China’s growing effort to build what authorities describe as “holistic personnel archives” — vast, integrated surveillance profiles that combine physical movements, digital activity and behavioral data into a single continuously updated record.
NetAskari had accessed what appeared to be a demonstration version of a tracking platform developed for the Public Security Bureau in Zhangjiakou, the city in Hebei province that hosted the 2022 Winter Olympics.
Although intended as a test system, the platform contained real data, offering a rare glimpse into how China’s surveillance apparatus is evolving from isolated camera networks into an interconnected, predictive system of social control.
China already operates the world’s largest CCTV network, and the government’s “Xueliang,” or “Bright Eyes,” initiative aims to merge these previously separate surveillance systems nationwide. The Zhangjiakou platform demonstrated how detailed that monitoring can become.
According to the report, the software can identify the exact train carriage and seat number occupied by a target traveling from cities such as Beijing or Shanghai. It also integrates facial-recognition images collected at ticket gates in local ski resorts directly into the tracking system. The movements of individuals known to the researcher who had recently visited ski resorts in Zhangjiakou were reportedly mapped in precise detail.
The system collects a wide range of behavioral data, including gasoline purchases, shopping habits and visits to politically sensitive “petition areas.” Authorities then combine this information with location records and digital footprints in an attempt to create a seamless profile of each individual.
Foreign nationals — particularly journalists and citizens of Western countries — appear to receive special attention within the system. The platform’s internal statistics reportedly showed a disproportionate focus on citizens from the “Five Eyes” alliance: the United States, the United Kingdom, Australia, New Zealand and Canada.
Some journalists were marked with a special “trackable” designation, allowing authorities to automatically generate alerts the moment they entered a particular area.
NetAskari said these technological developments fundamentally change how Chinese authorities monitor reporters. In the past, journalists traveling to sensitive regions such as Xinjiang often attempted to evade physical police surveillance. But with access to mobile payment histories, ticket purchases and social connections, authorities can now predict travel plans and quietly pressure sources behind the scenes.
“They don’t need to send two or three cars to follow you anymore,” the researcher said.
One of the system’s most powerful features is its ability to analyze relationships between people. Instead of relying solely on traditional surveillance, the platform automatically generates network diagrams showing who interacts with whom and how frequently, based on camera footage and other collected data.
The technology behind these “relationship models” has been developing for years. In 2019, the Chinese technology company Hisense filed a patent describing a system designed to map travel histories, phone records and vehicle usage.
More recently, in 2025, Shanghai’s Putuo Public Security Bureau awarded a $200,000 contract for the development of a “Holistic Personnel Archive System.”
The report also draws comparisons with debates in Western democracies over surveillance technologies such as those associated with Palantir Technologies. However, NetAskari argued that China differs because there is little public oversight or meaningful debate surrounding police surveillance powers.
“In Western democracies, there are debates,” he said. “In China, this debate doesn’t exist at all. The police and the Ministry of State Security just do whatever they want with relatively little oversight.”
The researcher concluded that within such a system, individuals are reduced to data points — patterns and algorithms that can be monitored, shaped and controlled as needed by the state.
