摘要： An image signature creating method includes: creating a map by partitioning a still image using rings defined by concentric circles radially spaced apart from each other by a predetermined interval and radial lines circumferentially spaced apart from each other by a predetermined angle, the center of the still image being that of the concentric circles; and creating an image signature from the created map on the basis of distribution of pixels in regions defined by the rings and the radial lines. Accordingly, distribution of illegal contents is prevented and interrupted by search for and discrimination of a still image illegally deformed by a copying of or an intended attack on the still image.

摘要： Disclosed are (A) an acrylic pressure-sensitive adhesive; and (B) an acrylic pressure-sensitive adhesive comprising an optically anisotropic compound having at least one substituent which contains an alkyl group, alkenyl group or alkynyl group at a meta-position of a mesogen. A polarizing plate and a liquid crystal display using the same are also disclosed. The optically anisotropic compound ensures excellent compatibility with the adhesive and high birefringence. Thus, main properties such as adhesion, reliability and durability in the conditions of high temperatures or high temperatures and high humidity are not worsened. Moreover light leakage is prevented by efficiently controlling the birefringence caused by shrinkage stress of the polarizing plate.
