Abstract
A controller for user authentication and access control, configured to: store data representing a graph having: nodes representing data elements associated with accesses made using an access token; and links among the nodes representing connections between the data elements identified in details of the accesses. In response to receiving details of an access made using the access token, the controller updates the graph according to the details and identifies changes in the graph resulting from update. For each of the changes, the controller identifies a set of elements in the graph that are up to a predetermined number of degrees of separate from the change and evaluates the trustworthiness of user identities corresponding to the set of elements identified for the change. Based on the trustworthiness, the controller authenticates the user of the access and/or controls the access.
