Latest Patents
Barrows' latest patents include advancements in data driven role based security. One of his patents outlines methods, systems, and computer program products for controlling the performance of a requested user operation. This invention determines if a user can access data based on an obtained user context associated with the user. The user context identifies the location of an object representing a user relative to other objects within a hierarchical data structure. This context is utilized to derive a role for the user, and a control expression is accessed to govern access for the derived role. A set of permissions is formed for the user by evaluating the control expression using both the user context and a data context for the data. Ultimately, the user's authorization to perform the requested operation is determined from this set of permissions.
Another patent by Barrows provides a comprehensive approach to data driven role based security. At login, the system queries for a data context in connection with access to computing objects. When a request for access is received, one or more control expressions specified for the computing object are evaluated. This evaluation may reference the previously established user context or data context, returning a set of effective permissions. Access to the computing object is granted if the set of permissions includes the appropriate permission for the access request.
