Abstract
Digital data archival methods and systems are described, providing controlled and verifiable information destruction. In one embodiment, the method comprises storing digitally encoded information, wherein the information is encoded as a sequence of numbers or symbols using parameters defining an associated error correction ability of an error correcting algorithm based on a lifetime of the digitally encoded information. Errors are periodically added to the sequence of numbers or symbols, such that the digitally encoded information is recoverable from the sequence of numbers or symbols during the defined lifetime, and after a total of number of added errors exceeds the associated error correction ability, the digitally encoded information cannot be retrieved.
