Abstract
Techniques for secure public exposure of digital data include extracting n chunks, each containing Q bits, n=2(Q+1). A random mapping of each chunk to only one batch of M numbered batches is determined and stored securely. A bit based on a random key is combined at a location based on batch number with each of the chunks in the batch to produce a batch of enhanced chunks, each containing Q+1 bits. This is repeated with each non-overlapping batch of chunks, each enhanced chunk of the batch having one bit based on a different bit from the key. A unique set of the enhanced chunks is combined with a XOR to produce an encoded chunk, every bit of which is based on a bit from the key. An encoding vector B that indicates the unique set is stored securely. The encoded chunk can be safely exposed publically.
