Abstract
A storage application may provide protection of data accesses by clients without incurring metadata storage costs. A request to store a record may be received, where subsequent accesses to the stored data are protected by an access condition that includes a key or other metadata. To store the record, a composite record including the record and the security key may be generated and a detection code may be determined for the composite record. The record may then be stored along with the detection code. A request to access the record may then be received, the access request including an access key. The record and detection code may be retrieved and a new composite record including the retrieved record and the access key may be generated. Satisfaction of the access condition may be determined according to a new detection code generated from the new composite record.
