Context aware data protection

Abstract

A method, system, and computer usable program product for context aware data protection. Information about an access context is received in a data processing system. A resource affected by the access context is identified. The identification of the resource may include deriving knowledge about resource by making an inference from a portion of contents of the resource that the access context affects the resource, making an inference that the access context affects a second resource thereby inferring that the resource has to be modified, determining that the access context is relevant to the resource, or a combination thereof. The resource is received. A policy that is applicable to the access context is identified. A part of the resource to modify according to the policy is determined. The part is modified according to the policy and the access context to form a modified resource. The modified resource is transmitted.
