Methods, systems, and articles of manufacture for protecting data in an electronic document using steganography techniques

Abstract:

Various aspects described herein are directed to methods and systems that preprocess an electronic document or some data therein and conceal sensitive data in the electronic document by applying steganography to the data associated with one or more fonts. A steganography map is generated or updated to include steganography information about applying steganography to the data. Cryptography may be applied to the steganography map; and the electronic document may be transformed into a different document format.
