Patent ID: 7631362

Claim:
A computer implemented method for managing access to a resource, the computer implemented method comprising: identifying the user as a member of a peer group; identifying by a processor a set of user behavioral attributes from acts generated by the user while the user is using the resource; comparing by a processor the set of user behavioral attributes to a set of historical peer group behavioral attributes of the peer group to form a comparison; scoring by a processor each of the set of user behavioral attributes based on the comparison to form a set of scores, wherein each of the set of scores is a degree of difference of one of the set of user behavioral attributes from one of the set of historical peer group behavioral attributes; determining by a processor a composite score from the set of scores to determine an overall degree of difference of the set of user behavioral attributes from the set of historical peer group behavioral attributes; responsive to determining that the composite score exceeds a first composite score threshold, requesting by a processor a further investigation of the user and accepting an access request by the user; and responsive to determining that the composite score exceeds a second composite score threshold, blocking by a processor the access request from the user.
