Abstract

The invention discloses an access group-based privacy protection-supporting access authorization method. The access group-based privacy protection-supporting access authorization method includes the following steps that: existing access groups are initialized; new access groups are created in a customized manner; the access groups are dynamically distributed; and access is authorized. According to the access group-based privacy protection-supporting access authorization method of the invention, the correlation between the privacy preferences of the access groups and the attributes of accessors is analyzed, and proper access groups can be distributed for the accessors dynamically, and therefore, personalized privacy protection requirements can be satisfied.
