Both encryption and digital watermarking techniques need to be incorporated in a speech communication to address different aspects of speech content management. While encryption transforms original multimedia object into another form, digital watermarking leaves the original object intact and recognizable. The objective of research is to develop FPGA base real time, reliable and secure watermarking systems, which can be achieved through hardware implementations. Data-size is one of the major concerns of cryptographic systems. This paper also includes speech compression to overcome the effect of data rate increase due to addition of watermarking and decryption key.
