Patent CA-2304611-A1 (CA)
Title: Method for generating and verifying digital watermarks and for exchanging data containing digital watermarks
Inventor: PUN THIERRY
IPC: G09C5/00
Filed: 1998-09-28
Abstract: A method for generating digital watermarks and for exchanging data containing such watermarks is described. It is based on a watermarking technique which is robust against image transformation techniques such as compression, rotation, translation, scaling and/or change of proportion. It uses modulation of the magnitude components in Fourier space and adds/reads a template in the logpolar or log-log transform of the magnitude components. The template is used for analyzing scaling and rotation or change of proportion. In addition, the system applies cryptographic protocols and public key techniques for both, encoding the watermark and transferring watermarked data. Preferably, an author (CH) encodes the watermark using an asymmetric cryptographic key pair provided by a public key infrastructure (PKI) and registers the watermarked data at a trusted registration party (CCC) before transmitting the data to a receiving party (B). The latter can use the public key infrastructure (I) for verifying autorship. Data exchanged by the parties are encrypted using the cryptographic keys. In addition, image (video) originality verification is supported by the same asymmetric key pair as for content protection and for copyright protection.

IPC: A63F1/00
Filed: 1998-11-13
Abstract: A collectable card game that represents the unwritten rules of politics, economic and popular culture is disclosed. The game is designed for play by three to six players. The game has a card holder and a deck of playing cards. The card holder is designed to hold four different piles of cards: the Pick Up Pile, the Recycling Bin, the Litigation Fund, and the 501(c)(3) Pile. The deck of cards is composed of three different categories of cards: three-value cards, policy cards, and disaster cards. A three-value card represents a desired good or service the value of which is dependent upon the demographic category chosen by the player at the beginning of the game. A policy card is a card that may be played by a player against an opposing player to slow the opposing player's accumulation of three-value cards. A disaster card is a card that an unlucky player picks from the Pick Up Pile that generally forces a distribution of that player's three-value cards to the other players.

Patent CA-2317697-A1 (CA)
Inventor: BLELLOCH ROBERT H
IPC: C12Q1/02
Filed: 1999-05-28
Abstract: L'invention concerne une protéine de migration GON-1 dans C. elegans, ainsi qu'un gène gon-1 codant pour cette protéine. Cette protéine, ci-après dénommée GON-1, présente la même structure qu'une protéine produite par un ARN régulé positivement dans une cellule tumorale avancée. Bien que la protéine de la cellule tumorale n'ait pas été identifiée comme jouant un rôle dans la migration cellulaire, la protéine GON-1 qui lui est associée est nécessaire à la migration cellulaire et intervient dans la mise en forme de tissus ou d'organes. On peut donc en déduire que cette protéine constitue également une cible pour les modulateurs de la migration cellulaire et de la mise en forme de tissus.
