Abstract:
A method and system are disclosed for field level encryption of a document that provides a hardcopy having redacted sensitive information fields with multiple levels of access and an augmented reality view of the hardcopy displaying the unredacted sensitive information fields. Identification of the sensitive information fields may be accomplished via highlight color, user designation, or linguistic analysis. The identified fields are encrypted and may be stored separately, embedded in place, or embedded in a two-dimensional glyph. This information may be stored in association with a device identification of an authenticated mobile device and a document identification. A redacted hardcopy of the original document is output. A mobile device captures an image of the redacted hardcopy, decrypts the encrypted sensitive information fields, and generates an augmented reality view of the hardcopy with the previously redacted sensitive information fields visible on the display of the mobile device.
