  • Patent number: 7461261
    Abstract: The aim of the invention is to propose the generation, verification and denial of an undeniable signature which has a size smaller than the currently available undeniable signatures, i.e. less than 80 bits. This aim is achieved by the method to generate an undeniable signature (y1, . . . , yt) on a set of data, this method comprising the following steps: (1) transforming the set of data (m) to a sequence of a predetermined number (t) of blocks (x1, . . . , xt), these blocks being members of an Abelian group, this transformation being a one way function, and (2) applying to each block (xi) a group homomorphism (f) to obtain a resulting value(yi), in which the number of elements of the initial group (G) is larger than the number of elements (d) of the destination group (H).

  • Patent number: 7450161
    Abstract: Systems, computer readable media and methods for digital processing of images captured by a sensor to enhance intensity uniformity of the images. The sensor captures an image of a white light source. Then, using the captured image, a compensation factor for each pixel of the image sensor is calculated and stored in a memory. Next, an actual image is captured by the image sensor. Subsequently, the signal intensity of each pixel is modified using the corresponding compensation factor to enhance the uniformity of the actual image.
