    摘要： A method and system are provided to perform digital printing using error diffusion but without the usual problems of the anisotropy associated with that method. The method computes several error diffused digital images on a variety of rasters, and averages them with some chosen set of weights. The method works directly for printers with more than two choices per color per pixel, and can be implemented by defining super-pixels, even with the simpler printers that have only white and black or two color value per color coordinate.

    摘要： A method (and system) of securely communicating, includes using one of a preliminary secure transmission and exchange or acquisition of secret information that provides parties with a random sequence known only to first and second parties in communication with one another, and linking one of the first and second parties with a third party. The secure transmission of the secret information is made using a channel of communication at a time when fast communication is not desired.

    摘要： A method (and system) of conducting business electronically between a first party and a second party, includes providing a third party who knows the identity of the first party but no privacy-compromising information regarding a proposed electronic business transaction between the first and second parties, and conducting the electronic business transaction between the first and second parties through the third party such that the identity of the first party is kept from the second party.

    摘要： Techniques for generating dither masks are provided. A dither mask is generated by selecting a sequence of at least three original patterns comprising pixels of at least one of a first color and a second color. At least two patterns are interpolated to generate interpolated patterns in the sequence between the at least three original patterns. If a pattern having at least one specified characteristic exists in the sequence, the steps of interpolating between at least two patterns, and determining if a pattern having at least one specified characteristic exists in the sequence, are repeated. The interpolation is between at least one pattern from each side of the pattern having at least one specified characteristic in the sequence.
