Recently, China’s Ministry of State Security issued a warning highlighting the significant security risks associated with the improper collection, storage, and use of personal trajectory data. Trajectory data refers to information about an individual’s movements gathered through mobile phone geolocation, transit cards, payment records, facial recognition cameras, and other digital means. If such data is illicitly obtained or misused, it not only violates personal privacy but could also be exploited to map personnel flows in sensitive areas or even assist foreign entities in intelligence gathering and infiltration.The Ministry emphasized that certain commercial apps collect extensive location data without adequately informing users, raising concerns about cross-border data transfers. Additionally, many smart devices enable high-precision location tracking by default, further increasing the risk of data leakage. In response, authorities are advancing a classified protection framework for data management and strengthening oversight of sensitive personal information—especially movement-related data.Experts advise the public to enhance digital security awareness: carefully manage app permissions for location access, regularly delete unnecessary location history, and stay informed about official cybersecurity alerts. Only through coordinated efforts among government, businesses, and individuals can a robust defense against these emerging national security threats be established.
近日，中国国家安全部发布警示指出，个人轨迹数据的不当收集、存储与使用潜藏重大安全风险。所谓轨迹数据，包括通过手机定位、交通卡、支付记录、摄像头识别等方式获取的个人行踪信息。这类数据一旦被非法获取或滥用，不仅可能侵犯公民隐私，还可能被用于绘制关键区域人员流动图谱，甚至辅助境外势力开展情报分析与渗透活动。国安部强调，部分商业应用在未充分告知用户的情况下大量采集位置信息，存在数据跨境传输隐患；一些智能设备默认开启高精度定位功能，也增加了信息泄露的可能性。为此，相关部门正推动完善数据分类分级保护制度，强化对敏感个人信息特别是轨迹类数据的监管。专家建议公众提高数字安全意识，谨慎授权应用获取位置权限，定期清理不必要的定位记录，并关注官方发布的网络安全提示。只有政府、企业与个人共同筑牢数据安全防线，才能有效防范潜在的国家安全风险。
