Abstract
A method and an apparatus for managing data for providing a predetermined piece of information according to access restriction information established with regard to each piece of data are provided. The method includes: establishing the access restriction information with regard to the data when the data is stored; and determining whether an access to the data is permitted by detecting access valid time of the data from the access restriction information. The present invention establishes access valid time with regard to importance data accessed by a user and establishes a user'"'"'s access denial to the importance data having access valid time exceeding the established access valid time so as to reinforce security, thereby preventing the important information from being externally leaked. Also, the present invention establishes a time limit and a cycle of each piece of important information, thereby facilitating the management of important information.
