Abstract
A secure chain data structure is stored by grouping source data into blocks of data, calculating a hash value of an immediate prior block for each block of said blocks of data and a hash value of a non-immediate prior block for at least some blocks of said blocks of data, associating the hash value or values of each block with each block of said blocks of data, and storing said blocks of data and their associated hash values to form a secure chain data structure. Trust can be provided to blocks in the secure chain data structure by later blocks containing valid hash values of prior blocks including valid ones of the hash values of non-immediate prior blocks.
