Definition
Temporal Access Control is the process of granting or denying access to resources and data in a system upon evaluation of time-dependent conditions. A mechanism is provided to decide if requests for access should be granted or denied based on a set of temporal access control policies. These policies are defined according to a temporal access control modeland formalized using a policy specification language including temporal expressions. As a simple example, a temporal access control policy may grant to an employee the authorization to access the enterprise database only during her work shift, and to update a specific table only after 5 p.m. More complex temporal conditions are supported as, for example, the authorization for an employee to read data from a database table in a certain interval of...
