DATA LEAK DETECTION USING SIMILARITY MAPPING

Abstract:

The computer-performed automatic estimation of data leaks from private stores into public stores. The owner of the data in the private store can then be alerted to the estimation so the cause of such leaks can be remedied. The estimation is based on comparisons between similarity mapping results for data within the private store with similarity mapping results for data within the public store. As an example, the one-way similarity mapping could be a fuzzy hashing or a provenance signature.
