Abstract
A system and method comprises receiving a write request from a client to store data at first and second non-sequential locations of a storage medium. The data of the write request is recognized as not being a predefined data pattern, and a first encryption method is applied to the data of the write request before it is stored at the first and second non-sequential locations of the storage medium. Further, a second different encryption method is applied to content of an area between the first and second non-sequential locations, where the content of the area is recognized as being the predefined pattern.
