“…But due to the varied sizes of the databases it becomes impossible to control the accesses. Therefore some researchers came up with the idea of combining all the different types of models and making the work as one [7]. Thus many techniques are being adapted like combining of different models or forming of new models while others are extensions of the already existing models.…”

“…It can be prone to viruses as well. Also the identity of a subject in DAC is crucial because actions can get performed from another person's identity as in DAC a user can grant access right to another user and thus this a drawback of DAC as it can be prone to Trojan horses and malicious attacks [6] [7][8] [9].…”

“…It gives authorization to the user to access the information according to the roles the user performs. Roles can be defined as job functions of an organization and the roles are assigned to the user according to the organizational requirements [2][5] [7]. It can be seen as a variation of the access matrix.…”

“…In the second stage a modified DAC model is applied to control the 'read' mode as it filters out the non-accessible data from the results obtained from the first stage. In this way the user can access the data that he is authorized to access [7]. Another migration observed was to TRBAC that is Temporal RBAC.…”

Hospitals across the world are adapting to Electronic Hospital Information Systems and are moving away from the manual paper systems to provide patients efficient services. Numerous Access Control Models have been deployed for securing patient privacy one of them being Role Based Access Control Model (RBAC). The current models merely allow access on the basis of roles and role hierarchy without actually understanding the real intention of the person accessing the system. This could lead to a compromise of patient privacy and thus new methods have been evolving. In this survey we will see an evolution of the access control models which lead to the discovery of KC-RBAC (Knowledge Constrained Role Based Access Control) Model which takes into consideration the knowledge related to the medical domain along with the role to provide authorization.
