ABSTRACT:
Files can be reassembled from fragments by (a) accepting (or determining) adjacency scores for each pair of fragments from a set of fragments, (b) identifying header fragments from among the fragments of the set of fragments, and (c) for each of the header fragments identified, reconstructing a corresponding one of two or more files from the fragments of the set of fragments such that the sum of the adjacency scores are optimized. Any of the fragments, other than the identified header fragments, are permitted to belong, at least provisionally, to more than one of the at least two files when reconstructing the file(s).
