Reversible tamper localization watermarking for computed tomography images / Khor Siew Jiau - Kuantan, Pahang : UMP, 2013 - xv, 65 p. : ill. ; 30 cm. + 1 CD-ROM
Project paper (Bachelor of Computer Science (Software Engineering)) -- Universiti Malaysia Pahang - 2013
Bibliography : p. 38-39
The thesis discussed about the implementation on reversible tamper localization watermarking for computed tomography images. Cyclic Redundancy Check (CRC) is applied as a purpose to duplicate the least significant bits (LSB) of Region of Interest (ROI). The watermarking applied on the research is reversible and invisible to be seen. Tamper localization will occur on Region of non-Interest (RONI). The image of watermarked generated must have visual quality same with the original version. Schemes of the watermarking must be tested in a simulated operational environment for practicality verification. The reversible tamper localization (R-TL) watermarking scheme will be uses to compress the LSB embedded in the region of non-interest RONI is outside of the ROI to achieve the reversible process in ROI after tampering process is discovered. In conclusion, schemes of the watermarking will in effect implemented in practice to avoid cheat and enhance security of the information.
