Abstract
An input image is divided into segments. The segments may be reassembled to reform the input image. The order of the segments may be stored in an encrypted database for which approved applications have the decryption key but users do not. This allows the approved applications to determine the order and reform the input image without allowing users to do the same. To further increase the difficulty of reforming the input image, the segments may be transformed. Example transformations include rotation and mirroring. The encrypted database may store an indication of the transformation applied to each segment. The effort of reforming the input image without access to the database is increased substantially. The reformed input image may be stored in transient memory only, without being stored to long-term storage. Thus, the reformed image cannot be accessed from a file system by unauthorized users.
