ABSTRACT:
In a named data processing system, user ownership and verfication of data records is secured by assigning an unique record name to each data record, providing error checking covering both the data record and its associated record name, storing the data record, its associated record name and check code, and requiring the data record name to be provided in order to initiate a fetch operation. Further, the check code enables upon fetching, a verification that an incorrect data record was not inadvertantly fetched due to hardware or other failures. The association of a unique data name with each data record provides for self-descriptive data records thereby permitting the reconstruction of directories which describe the contents of various actual physical locations within an Input/Output system when such directions are lost or otherwise corrupted by hardware or other malfunctions.
