摘要： A signal component (e.g., a period signal component such as a sinusoid) is added (210) to an original color image to form a modified color image, with the goal of embedding the signal in the image so that it is imperceptible to a human viewer. A comparing operation (240) uses a model of human perception to measure the perceptual difference between the original and modified images, identifying local areas of the modified image where the signal difference exceeds a threshold, indicating that the signal is perceptible to a human viewer. Using the perceptual difference measurement data; the signal is attenuated in the identified local areas that indicate a perceptually unacceptable difference, and this modified signal component is then added (210) to the original color image in a next iteration. Perceptual difference measurement and signal attenuation are iterated until the comparison operation determines that the signal difference is perceptually acceptable. The technique takes advantage of the fact that, although the spatial frequencies of the embedded signals are well within the range of spatial frequencies to which humans are normally quite sensitive in the luminance (black-white) vision channel, this sensitivity does not extend to the color vision bands. In an illustrated embodiment, a set of sinusoidal signals that form a grid are added to the color image; location (i.e., decoding) of the sinusoids, which does not require the original color image, allows computing a geometric mapping from an image with the embedded signals to the original image.

摘要： PROBLEM TO BE SOLVED: To provide a method and system for encoding a signature into a digital image and auditing a digital subject image to determine, whether it has been derived from the encoded image.
SOLUTION: A method and system for embedding signatures inside visual images in both digital representation and print or film. A signature is inseparably embedded within the visible image, and persists through image transforms, that include resizing as well as conversion to print or film and back to digital form. Signature points are selected from among the pixels of original image. The pixel values of the signature points and surrounding pixels are adjusted by an amount that is detectable with a digital scanner. The adjusted signature points form a digital signature, which is stored for future identification of subject images derived from the image. The signature is embedded inside an image, by locating the relative extrema in the continuous space of pixel values and selecting the signature points from among the extrema.

摘要： A system quickly verifies that the content of an image has not been changed since an earlier time when the content of that image was stamped. The system consists of a stamping process that embeds stamping information into a source image and produces a verification key, and a verification process that extracts stamping information from a stamped source image based on the verification key. Furthermore, the verification process produces an image itself, from which the verification can be readily judged visually or by use of a computer or other display device. In the verification process, the changes in an image can be detected and localized. The image stamping process further includes an error diffusion process so that the effects of combining the stamping information with the original image are not readily perceptable. An image is safeguarded against malicious manipulations and the proprietary rights are protected by maintaining the integrity of the image content.

摘要： PROBLEM TO BE SOLVED: To enable multiplex noise in multilevel image data and to reversibly embed visible additional information with distribution in which the noise is multiplexed, while maintaining an atmosphere of the multi-level image data to be embedded. SOLUTION: When the noise is multiplexed in the multi-level image data and the visible additional information with the distribution in which the noise is multiplexed is embedded, information representing whether the noise is multiplexed for each pixel is input as the additional information. It is determined whether a pixel of interest in the multilevel image data is present at a position, where noise is to be multiplexed, on the basis of the additional information (S106). When it is determined that the pixel of interest is a the position where noise is to be multiplexed, a second bit region for multiplexing noise is specified among bit construction forming the pixel of interest on the basis of a state of a first bit region (S110), and bit information is reversibly changed for the second bit region of the specified pixel of interest (S112, S114).
