Abstract
An information security system that includes a data control engine configured to receive a data file and to segment the data file into a set of data blocks that each contain a portion of data from the data file. The data control engine is further configured to associate the set of data blocks with a reference tag and to store an association between the set of data blocks and the reference tag. The data control engine is further configured to identify an access key for encrypting each data block, to encrypt each data block with a corresponding access key, and to store an association between each data block and each corresponding access key. The data control engine is further configured to store each data block in a memory and to store location information identifying the location of each data block in the memory.
