Title: A scaling independent technique for watermarking images
Inventor: RYAN JOHN O
IPC: H04N7/26
Filed: 2000-08-01
Abstract: A robust technique to prevent illicit copying of video information notwithstanding the use of image scaling is presented. A watermark is embedd ed into the video signal at different scales (i.e., sizes). The watermark is maintained at each scale for a predetermined time duration that is sufficien t to allow the detector circuit in a digital format recorder to detect, extrac t, and process information contained in the watermark. At the end of the predetermined time duration, the watermark is changed to a different scale preferably on a pseudo-random basis to ensure that each one of all the scale s in a predetermined scaling range is achieved a predetermined number of times . In this way, a particular scale that has the counter effect of restoring the  watermark to its original position and size can be identified and used to allow the watermark to be detected.

Title: Method and apparatus for preventing piracy of digital content
Inventor: JAFFE JOSHUA M
IPC: G06F21/75
Filed: 2000-05-16
Abstract: A secure cryptographic rights unit (225) for cryptographically regulating access to digital content (215) includes an interface control processor (235) and a specialized cryptographic unit (260) that protects access to a memory (265). The cryptographic unit produces content decryption keys (267) by using stored rights keys to transform other data received from the control processor (235). Because the control processor (235) does not have the ability to directly access the protected memory (265), the security can remain effective even if the control processor (235) is compromised. To prevent reverse engineering of the cryptographic transformations, the invention provides for an algorithm generator that uses random sources to produce algorithm definitions in machine-readable form. Because the generator itself does not contain any secrets, it can be submitted for open review. Other features allow for the content provider (200) to audit the access (296) of the user (290) who can obtain the decrypted content (275) through an output device (280).

Abstract: L'invention concerne un système de sélection du mode de vol d'un avion utilisant des menus créés sur ordinateur et des touches en cerclage programmées afin de permettre l'accès à un plus grand nombre de modes de vol dans un espace plus réduit que ce qui est actuellement possible, au moyen d'un sélecteur de mode de vol constitué uniquement de commutateurs spécialisés classiques, de témoins lumineux et de tableaux de commande câblés. Des connexions bus série entre le sélecteur de mode de vol et le calculateur de commandes de vol de l'avion réduisent la quantité de câbles utilisés pour le sélecteur de mode de vol, en comparaison avec le protocole actuel qui utilise des câbles spéciaux pour chaque commutateur spécial du sélecteur de mode de vol. L'utilisation d'affichages et de menus créés sur ordinateur facilite l'expansion du sélecteur de mode de vol sans avoir à ajouter des interrupteurs et des témoins lumineux. L'inclusion d'une table de recherche d'informations graphiques dans le contrôleur de processeur, laquelle table est séparée du logiciel du contrôleur, permet de procéder à des changements sur le sélecteur de mode de vol par simple changement de la table de recherche. Le sélecteur de mode de vol comprend également un affichage de messages destinés au pilote permettant de transmettre des messages textuels au pilote de l'avion.

Abstract: In connection with the segmenting of a digital image divided into small elements (pixels) and acquired with a camera having several colour channels,  to discern an object from a background, the daylight locus and the colour locus of the camera are, a priori, modelled after to the body reflectance characteristic of the subject. In this way a normal vector (nS) to the daylight locus is determined a priori and for each pixel, the scalar product  between a colour vector (cf) of the element in the form of the response from  the colour channels of the camera and the normal vector of the daylight locu s is calculated, following which the element is characterized as representing object or background on basis of the calculation result, the elements characterized as objects (1) being assigned one value and the elements characterized as background being assigned a second value. On basis of the segmented image a control signal for an implement (4) is derived.
