ABSTRACT:
A system and method for encrypting content in an adaptive manner. Portions of data to be encrypted are identified and an encryption ratio that specifies the one or more portions of data to encrypt and other portions of data to not encrypt is determined. The data is then encrypted based on the encryption ratio.
