On Secure Digital Image Watermarking.

The DFRFT digital watermarking provides two additional freedom like DFRFT powers and watermark location that results in the possibility to embed more number of watermark bits than watermarking domains.

This thesis focuses on combining the chaotic scrambling and wavelet watermark embedding to achieve a hyperchaotic digital watermark to encrypt digital products, with the human visual system (HVS) and other factors taken into account.

Nowadays, the transmision of data is very important and it has been carried out by using digital media (Internet, e-mail). There are some problems that may occur in the transmission of digital media data which is associated with data security level to be sent. Base on that condition, the thought of doing data concealment are emerge. Digital image is one of the most common media used by the community. Digital watermarking is one of cryptography methods which used to hide data into digital image so that the data sent cannot be identified by the irresponsible people. Data encryption is used to improve the security of data to be sent. Internet as the world's largest network system that connects nearly all computer worlds, making all the c omputers in the world is increasingly easy to exchange data. There are so many digital data falsification has occurred. Digital falsification of data aimed to succeed the counterfeiting syndicate these hidden plans. the falsification problem of digital data will from be resolved by applying the watermarking using LSB method (Least Significant Bit).
