Integrated Joint Operations Platform (IJOP)

The Integrated Joint Operations Platform is the system Chinese authorities use for mass surveillance in Xinjiang. It aggregates data about individuals, applies criteria to flag those it deems potentially threatening, and prompts officials to investigate them. Some of those flagged are detained and sent to political education camps and other facilities.

Almost everything known about how it works in practice comes from a single piece of research, and its provenance is worth stating plainly because it determines how much weight the detail carries.

HOW IT BECAME KNOWN

Human Rights Watch first reported on the platform in February 2018. In early 2018 the organisation obtained a copy of a mobile application used by police in Xinjiang to communicate with the system, and reverse engineered it. The resulting report, published May 2019 and led by senior China researcher Maya Wang, describes what the system actually collects and what it treats as suspicious.

This is not a leak, a whistleblower account or an official disclosure. It is a technical analysis of the software officials use, which is a stronger evidential basis than most reporting on Chinese surveillance, and it is also a snapshot of one application at one point in time.

WHAT THE ANALYSIS FOUND

Officials use the app for three broad functions: collecting personal information, reporting activities or circumstances deemed suspicious, and prompting investigations of people the system flags as problematic.

The significance lies in what counts as suspicious. Reported triggers include ordinary behaviours that would be unremarkable elsewhere — the use of WhatsApp, or of a VPN. The system does not primarily identify criminal conduct; it identifies deviation from expected patterns, and treats deviation itself as grounds for investigation.

That is a different proposition from every other system in this catalogue. A risk score in a Western criminal justice system predicts reoffending among people already arrested. This flags people who have done nothing that any legal system treats as an offence.

REPORTED DEVELOPMENTS, AT LOWER CONFIDENCE

Analysis published in 2024 to 2026, attributed to Citizen Lab and the Australian Strategic Policy Institute and relayed through secondary sources, describes an upgraded platform integrating real-time payment data, machine learning models trained on historical detention data, connection to national databases so that a Xinjiang flag can trigger restrictions elsewhere, and links to the Sharp Eyes network in rural areas.

This site has not been able to examine the underlying reports directly, and records these as reported rather than established. The machine-learning claim is notable if accurate, because a model trained on who was previously detained would encode and reproduce the demographic profile of prior detentions — the feedback problem documented elsewhere on this site, in a context where the consequence is internment rather than a patrol allocation.

IS THERE A CASE FOR IT

This is one of the few entries in this catalogue where the balance section cannot be filled in on the usual terms. The stated official rationale is counterterrorism and stability maintenance. No independent evidence has been identified that the system prevents violence, and its documented function — flagging lawful behaviour for investigation leading to extrajudicial detention — is not a policing purpose that has a legitimate counterpart to weigh.

Recording that plainly is more honest than manufacturing symmetry. Where this site sets out competing arguments elsewhere, it is because both sides have a case that can be evidenced.

WHAT IS NOT ESTABLISHED

The current operational state of the system is not independently verifiable.

The proportion of people flagged who are subsequently detained is not established.

The reported 2024-2026 upgrades have not been verified against primary sources by this site.

Independent verification is structurally constrained, as it is for all entries concerning China on this site, and rests on human rights researchers and investigative analysis working around significant state restrictions rather than on official disclosure.
