The Ministry of State Security of China (MSS) has published a warning about the risks associated with the activities of foreign companies collecting biometric data under the guise of cryptocurrency giveaways. Special attention is given to iris scanning, which, according to authorities, poses a threat to national security. The warning, published on the official MSS account on WeChat, indirectly refers to the project Worldcoin, co-founded by OpenAI CEO Sam Altman.
MSS emphasizes that the collection of biometric data, such as iris scans, by foreign companies could lead to serious privacy violations. In one described case, an unnamed company offered cryptocurrency tokens in exchange for biometric data, which was then transferred abroad. This raised concerns about the possible use of such data for purposes that threaten state security. Chinese authorities point to the risks associated with transferring sensitive information abroad, including its potential use by foreign intelligence for creating deepfakes or infiltrating secure facilities.
Although MSS does not directly name Worldcoin, the description of a project using iris scanning to create cryptographic identifiers clearly refers to Sam Altman's initiative. Worldcoin offers users tokens in exchange for biometric data, aiming to create a global identification network. However, the project has already faced regulatory pressure in Germany, France, and Kenya, where authorities have expressed concerns about informed consent, data storage, and the potential for mass surveillance. In China, where personal data protection is considered a state priority, such practices raise special alarms.
The MSS warning underscores that biometric data is a state-significant asset whose protection is directly tied to the national security of the PRC. According to the Personal Information Protection Law (PIPL) adopted in 2021, China strictly regulates the processing of personal data, including biometric. Authorities note that the leakage of such data could be used for cyber espionage or other harmful actions. As an example, MSS cites instances where stolen biometric data was used to create deepfakes that pose threats to the security of facilities.
China's reaction to Worldcoin's activities reflects a broader global trend of tightening control over biometric data. In 2025, China is implementing mandatory biometric identification in the banking system, highlighting the importance of protecting such data. Meanwhile, the international community, including countries in Europe and Africa, is also expressing concerns about projects like Worldcoin. Regulatory bodies require transparency in data collection and storage, as well as strict adherence to privacy standards.
The warning from the Ministry of State Security of China underscores the growing concern of authorities about the use of biometric data by foreign companies. Pointing to risks to national security, China signals its intention to tighten control over such practices. Worldcoin, like other projects using biometrics, must adapt to strict regulatory requirements or face further restrictions. This warning serves as a reminder that in the digital economy era, the protection of personal data remains a key priority for states worldwide.
