    Abstract: A method and system for encrypting a video compressed with MPEG-4 FGS compression with minimal overhead is provided. The encryption system encrypts the video into independently encrypted segments that can be either a video packet or a video block. When the encryption system encrypts based on video packets, it encrypts the data to ensure that the encrypted data does not emulate any video packet delimiting markers. When the encryption system encrypts based on video blocks, it encrypts the coded bitstream for each video block independently, from the most significant bitplane to the least significant bitplane, using either a stream or a block cipher. After all the video blocks are independently encrypted, the encryption system partitions the encrypted data into video packets and adds a buffering bit, if necessary, to prevent emulation of video packet delimiting markers. The encryption system may generate an initialization vector for each independently encrypted segment.

    Abstract: A digital watermarking method performs tonal detection on a signal (e.g., audio) to identify tonal and non-tonal components. These components are analyzed to compute appropriate weighting of a digital watermark for the tonal and non-tonal components. This tonal detection method is also used in recovering the watermark. A decoding method performs tonal detection on a watermarked signal, computes weights for tonal and non-tonal components, and recovers the embedded watermark using the weights. The same or different watermark embedding schemes may be used to embed digital watermarks in the tonal and non-tonal components. Tonal analysis is used in conjunction with frequency and temporal shaping to adapt the digital watermark to the signal in which it is embedded.

    Abstract: A digital watermark detector uses weighting functions to enhance watermark detection. The weighting function applies more weight to parts of a digitally watermarked signal that are more robust to distortion. As such, the method provides for more reliable watermark detection, especially in applications where distortions, such as lossy compression or analog conversion, more accurate detection more difficult. In one version of the method, the detector projects the watermarked signal into a pseudorandom direction specified by a key, applies the weighting function, and extracts auxiliary data symbols from the projected signal by quantizing the projected signal and deriving the symbol values based on the quantization.

    Abstract: A technique for hiding of data, including watermarks, in human-perceptible images, that is, image host data, is disclosed. In one embodiment a method comprises three steps. In the first step, data to be embedded is inputted. In the case of a watermark, this data is a unique signature, and may be a pseudo-noise (PN) code. In the case of hidden data to be embedded in the host data, this data is the hidden data itself, or the hidden data as spread against the frequency spectrum by a pseudo-noise (PN) code. In the second step, the inputted data is embedded within the host data, in accordance with a perceptual mask of the host data. The perceptual mask determines the optimal locations within the host data to insert the inputted data. In the case of images, these optimal locations are determined by reference to the human visual system. In the third step, the host data, with the embedded data, is further masked by a non-frequency mask. In the case of image data, the non-frequency mask is a spatial mask.
