Core Viewpoint - The newly released national standard "Technical Requirements for Information Clearing of Electronic Products" will be implemented on January 1, 2027, mandating electronic product manufacturers to incorporate a one-key information clearing function in their devices to mitigate data leakage risks associated with second-hand electronic products [2][3][9]. Background - The risk of data leakage from second-hand electronic products has become increasingly prominent due to the rapid turnover of devices in the digital economy, necessitating a standard to ensure data security during the circulation of these products [3][4]. - The standard aims to fulfill the requirements outlined in the State Council's action plan for promoting the recycling of electronic products, thereby safeguarding data security and fostering a healthy second-hand electronic product trading industry [3][4]. Technical Requirements - The standard specifies that manufacturers must implement a one-key information clearing function, with strict data overwriting requirements: at least 2 overwrites for mobile devices and solid-state drives, and at least 3 for traditional hard drives to ensure data cannot be recovered [7][8]. - The information clearing methods include data overwriting and block erasure, ensuring that data is irreversibly inaccessible [6][7]. Management Measures - Manufacturers are required to provide built-in information clearing functions or external tools for data clearing, with clear communication to users regarding the scope and impact of the clearing process [8]. - Recovery operators must verify the effectiveness of the data clearing before selling second-hand products, and products with unremoved user data are prohibited from resale or export [8][9]. Implementation and Compliance - The standard serves as a legal framework supporting various laws related to cybersecurity and data protection, with a transition period of 13 months to allow companies to adapt their products and management systems [9].
