Abstract

This paper presents a watermarking technique with fast encryption and compression. Recently a number of algorithms exist for watermarking and encryption. Their drawbacks are size, security and time for execution. Compression is necessary to maintain size small where bandwidth and storage capacity is limited. A loss-less compression technique is used to compress speech signal. Due to compression, vacant places are created. These vacant places are used for watermark. In the proposed encryption technique size of encrypted data is increased by only 12.5%. Execution of encryption is faster than present unbreakable algorithms. The proposed encryption is also highly secured and can be used for real-time application and saving signal. Watermark will exist even after signal cropping. © 2010 IEEE.
