Abstract
A biometric watermark system and method generate a biometrically encoded bitstream from biometric data of a user and from electronic data to be transmitted to the user. The encoded bitstream has the biometric data acting as a biometric watermark. The encoded bitstream is then sent to a decoder of the user, with the biometric watermark providing security in the transmission in order to prevent unauthorized users from extracting the electronic data. The decoder utilizes the biometric data of the user to decode the biometrically encoded bitstream, so as to extract the biometric watermark, and to securely retrieve the electronic data.
