Abstract

See full text

Embodiments of the present invention provide an approach for protecting visible data during computerized process usage. Specifically, in a typical embodiment, when a computerized process is identified, a physical page key (PPK) is generated (e.g., a unique PPK may be generated for each page of data) and stored in at least one table. Based on the PPK a virtual page key (VPK) is generated and stored in at least one register. When the process is later implemented, and a request to access a set of data associated the process is received, it will be determined whether the VPK is valid (based on the PPK). Based on the results of this determination, a data access determination is made.
