Abstract
A method and system for automatic deletion of information based on time synchronization and trusted counting is provided, the method including: defining different data structures including configurations in a normalized manner; setting triggering conditions for automatic information deletion, including conditions for automatic deletion based on time synchronization and/or based on trusted counting; maintaining synchrony of the configurations across different domains; and after satisfying the triggering conditions, making an information source domain and/or an information propagation domain perform the automatic information deletion. Considering that existing data deletion mechanisms cannot delete information according to preset retention periods, the present application employs synchrony across system clocks to perform automatic deletion of authorization information under circulation after a certain time period, and further limits a circulation count for information of interest so as to ensure that the information and its copies are all deleted after reaching a preset maximum permittable circulation count.
