Segment deduplication system with encryption and compression of segments
First Claim
1. A system for storing encrypted compressed data, comprising:
- a processor configured to;
determine whether an encrypted compressed segment has been previously stored, wherein the encrypted compressed segment was determined by breaking a data stream, a data block, or a data file into one or more segments and compressing and then encrypting each of the one or more segments;
in the event that the encrypted compressed segment has not been previously stored, store the encrypted compressed segment; and
a memory coupled to the processor and configured to provide the processor with instructions.

Abstract
A system for storing encrypted compressed data comprises a processor and a memory. The processor is configured to determine whether an encrypted compressed segment has been previously stored. The encrypted compressed segment was determined by breaking a data stream, a data block, or a data file into one or more segments and compressing and then encrypting each of the one or more segments. The processor is further configured to store the encrypted compressed segment in the event that the encrypted compressed segment has not been previously stored. The memory is coupled to the processor and configured to provide the processor with instructions.
