ABSTRACT: Access control has made a
long way from 1960s. With the advent changes of technologies pertaining to
location transparency in storage of data, there arises different access control
scenarios. Cloud storage, the predominant storage that is being in use
currently, also paves way to various access control problems. Though there are
various access control mechanisms such as RBAC, ABAC, they are designed on the
user’s perspective such as the role held by the user or other attributes
assigned to the user. A new access control mechanism called object relationship
based access control (RoBAC) has been developed based on the relations held
among the users. The policy decision of access control is based on the
relationship among the classes followed in the Java programming. Results have
shown that this model best suits various scenarios in the cloud environment,
and it also shows that the time for making decision either to allow or to deny
is reduced compared to the existing system.
