Abstract: Disclosed herein is a hierarchical data storage and retrieval system implemented using a computed statistically unique signature for the content of given computer data as its basis. The data storage and retrieval system can be used to catalog computer information for easy indexing and retrieval. The signature is computed by any number of techniques so long as it is able to produce a statistically unique signature, one example being the SHA-1 algorithm. The system is able to reduce the amount of data that is stored and the time required for retrieving the data. Provide a way to move electronic data in an encrypted secure manner that requires the complete data set being moved for decryption of the data. Even if a portion of the data is compromised that portion would still remain secure. The data is encrypted and separated into two or more portions all of which would be needed to decrypt the data.
