Abstract: A method of processing semiotic data includes receiving semiotic data including at least one data set P, selecting a function h, and for at least one of each data set P to be collected, computing h(P), destroying data set P, and storing h(P) in a database, wherein data set P cannot be extracted from h(P). The method further includes selecting a private key/public key (K, k) once for all cases, one of destroying the private key K and sending the private key K to a trusted party, and choosing function h as the public encryption function corresponding to k.

Abstract: A method (as well as system and signal-bearing medium) of processing biometric data, includes receiving biometric data including a data set P, selecting a secure hash function h, and for each data set P to be collected, computing h(P), destroying the data set P, and storing h(P) in a database, wherein data set P cannot be extracted from h(P).

Abstract: A system, method, service method, and program product for defining and/or managing entitlements and/or authentication entitlements to resources in a computer networking environment is disclosed. Upon receiving one or more dynamic events, the invention verifies one or more users (a selected user) has (entitlement) attributes that satisfy one or more access criteria to access one or more resources. The invention then permits and/or provides access to one or more resources for the selected user over one or more networks without revealing the identity of the selected user to the resource provider.

Abstract: 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.

Abstract: A method (and system) for guaranteeing authenticity of an object, includes providing a sample of material obtainable only by at least one of chemical and physical processes such that the sample is random and not reproducible, associating a number reproducibly to the sample by using a specific reader, and forming at least one coded version of the number, the at least one coded version being obtained by a key signature, and the version being recorded into an area of the object.

Abstract: A method (and system) for preventing counterfeiting and cloning of smart cards, includes providing a smart card with a cryptographic structure for authorizing the smart card which can not be accessed completely by a predetermined small number of readings. The cryptographic structure can be built only by whoever emits the card or an agent thereof.

Abstract: A method and apparatus for authenticating (or identifying) a subject, includes using one or a plurality of biometric measurements for authentication (or identification) without any sharing of the subject's biometric data with a party requesting authentication.

Abstract: A method (and system) of printing, includes forming a matrix of pixels, determining an order of printing of the pixels, the determining including finding a weight of the pixels and printing a pixel having a highest weight, and reordering the remaining pixels and printing a pixel having the greatest weight of the remaining pixels until all pixels have been printed.

Abstract: A method and apparatus which enables customers to remotely order goods from a merchant and receive the goods without revealing customer identity or address to the merchant, nor revealing what is bought to the bank or payment agency, and more generally to preserve as much anonymity as required such that no party except the customer has complete information about a transaction. The method uses clearing houses or encryption to break links between customer information and the merchant.

Abstract: A method (and system) of watermarking a half-toned image, includes grouping pixels of an image into blocks each containing a plurality of pixels, using as many gray levels as there are pixels in a block to halftone the image formed in the same blocks of pixels, based on a data set formed by the gray levels of the blocks of the halftoned image, generating at least one of a digital signature and a compressed version of the image, to form a generated unit, and inserting the generated unit in the halftoned image to form the watermark, by selecting how a predetermined number of pixels in a block are placed in the block.

Abstract: A business method is disclosed that uses a new type of alert system, with push technology, and furthermore provides one or more necessary tools for a user to respond to the alert. Some of these tools may include collaboration, access to web page, computational tools, dictionary, search results, translation tools, etc.

Abstract: A method (and apparatus) for guaranteeing authenticity of an object, includes providing a sample of material obtainable only by at least one of chemical and physical processes such that the sample is random and not reproducible, associating a number reproducibly to the sample by using a specific reader, and forming at least one coded version of the number. The at least one coded version is obtained by a public key encryption, and the version is recorded into an area of the object.

Abstract: A system and method to print grey scale or color images using fewer colors of ink than in the original image. This method distributes the error made at each point (due to the embodied approximation) to the neighbors of that point while obtaining some chosen predetermined patterns for several colors kor grey levels. Getting these predetermined patterns and essentially predetermined patterns for all colors in turn reduces the anisotropic algorithmic artifacts, suppresses edge over-enhancement and allows for good performances on patches of uniform and almost uniform colors or grey levels.

Abstract: An alternative to classical spread spectrum communication systems is based on synchronization of dynamical systems which can resist noisy transmission channels, jamming, gain modulation, multiple time delays, and self-jamming.

Abstract: A technique which combines the advantages of blue noise and clustering obtains more pleasant "blueish" effects in the rendering of the grey levels for which the original multicell mask generates unwanted periodic representations. Such original multicell clustered dither array patterns which are undesirable are replaced by less periodic ones while preserving all benefits of the classical methods, and in particular, leaving the nicest patterns unchanged. An automated process redistributes the locations of the threshold values corresponding to undesirable grey levels to obtain more pleasant "blueish" effects in the rendering of the grey levels.
