摘要:
In one example, a method may include performance of a hash function on a digital sequence so as to generate a hash value that corresponds to the digital sequence. Next, the digital sequence may be broken into data pieces, and each data piece hashed to produce a corresponding hash value for each data piece. Then, a recipe may be produced that includes instructions which, when executed, may generate the digital sequence from the data pieces referenced by their corresponding hash values included in the recipe. Among other things, the hash values may enable reutilization of redundant data sequences by serving as pointers to the data pieces that the hash values respectively represent.
