2. Apr. 10, 2003 TOSHIBA Corporation 2 Features of HIDE Satisfying the following requirements Robustness against various kinds of operations and attacks Especially, robust against scaling and filtering Low false positive error rate Good transparency Sufficient capacity for copy control usage Baseband detection, independent from the compression methods and formats

3. Apr. 10, 2003 TOSHIBA Corporation 3 Robustness/Survivability HIDE technology is robust against various kinds of attacks: Vertical and/or horizontal scaling MPEG2/MPEG4 compression and decompression VHS recording D/A and A/D conversions Random noise addition Gamma correction Jitter attack Rotation attack Stirmark attack

4. Apr. 10, 2003 TOSHIBA Corporation 4 Robust against scaling In principle, HIDE is not affected by scaling of images Scaling and clipping cannot break the relationship between the original image and the embedded watermark reference image

5. Apr. 10, 2003 TOSHIBA Corporation 5 Transparency Sophisticated adaptive modulation based on characteristics of the original image for decreasing artifact caused by the watermark image Any annoying artifact can hardly be perceived in the watermarked image

6. Apr. 10, 2003 TOSHIBA Corporation 6 Capacity HIDE can carry 7 bits. The capacity can be extendedts more than 7 bits. It can fully support the DVD CCI states. Supports CCI states for remarking.

7. Apr. 10, 2003 TOSHIBA Corporation 7 Baseband detection The detection and remarking of HIDE technology are performed in the baseband domain. HIDE technology satisfies the requirements and functional needs for both analog and digital copy control systems. HIDE technology can handle images independent from compression methods and formats on any media.
