• A traceable and lightweight protection method for user information against leakage
• ZHANG Yan, HE Shen, SU Li
• Information and Communications Technology and Policy. 2020, 46(2): 46-49.
• Abstract ( 246 ) 　　
• In order to solve the problem of user information leakage, this paper proposed the lightweight protection method for user information. The digital contents such as ID number and phone number in the user information are encoded by the mask, stored with other information and decoded when used. The mask can be calculated by server flags, time and so on. When user information is leaked, only the encoded information will be exposed. By calculating the digital contents in the leaked information with the real digital content to get the mask, the source and time of information leakage can be traced, which can achieve the effect of anti-leakage and traceability.

• Abstract ( 505 ) 　　
• The outbreak of the Novel Coronavirus Pneumonia during the 2020 Spring Festival transportation has brought a huge impact on the people􀆳s production and life as well as social and economic development. Based on international experience, the focus of economic policy responses varies at different stages of the epidemic. After the outbreak of the Novel Coronavirus Pneumonia, the Chinese central government responded quickly, and local governments also successively issued a series of policy combinations to ensure the restoration of production, mainly including three aspects of policies. First, fiscal policies to protect the supply of epidemic prevention and control, and strengthen tax reduction. Second, financial policies to reduce corporate financing costs and prevent systemic financial risks. Third,employment policies to protect workers’ rights and benefits and share the cost of stable employment. With the gradual mitigation of the Novel Coronavirus Pneumonia, economic risks will gradually be exposed. Sober awareness should be maintained, and economic policy support should be further strengthened to promote a stable return to economic society.
