Threshold-based Collaborative Access Control (T-CAC)
Userpsilas information confidentiality and privacy rise with the increased usage of computers by various organizations. Abuse of privileges might occur when the trust is based on a single person. Moreover, access control models usually consider only regular policies and are not appropriate to unusual or exceptional circumstances. For instance, in case of emergencies many users might override the access control system in order to access unauthorized sensitive data which is undesirable.
