Abstract

A file is divided into chunks 2 and small data elements, such as bytes, are permuted between the chunks 3. Each chunk is hashed 4 to form a chunk hash, and each chunk hash is encrypted using one or more other chunk hashes 5 in a self encryption process. The chunk hashes and the encrypted chunk hashes are constituents of a mapping function. The chunks are distributed across various nodes of a peer-to-peer network. The permutation of the chunks contributes towards the effective encryption of the file. The file can be recovered using the mapping function.
