摘要： A system and method give a user control of personal data. A trusted center comprises a database for personal data, access conditions for the personal data, and a counter. A user loads personal data into the database and assigns access conditions to said data. The personal data is divided into at least two categories, each associated with a user's value. A third party requests access to personal data of a plurality of users, the request comprising search criteria. The trusted center identifies a first set of users matching the search criteria and returns the quantity of users in, and a sum of user's values for, the first set. The third party acknowledges all or part of the sum, and the trusted center returns the personal data of a second set of users for which the sum covers the user's values and updates the counters of user in the second set.

摘要： This invention concerns a safe data exchange method between two devices locally connected to one another. In a preferred embodiment, the first device is a security module containing a first encrypting key, said private key of a pair of asymmetric encrypting keys. The second device is a receiver comprising at least one second encrypting key, said public key of said pair of asymmetric encrypting keys. Furthermore each of the devices comprises a symmetrical key. The first device generates a first random number, which is encrypted by said private key, then transmitted to the second device, in which it is decrypted by means of the public key. The second device generates a second random number, which is encrypted by said public key, then transmitted to the first device, in which it is decrypted by means of the private key. A session key, used for safe data exchange, is generated by a combination of the symmetric key and the random numbers generated and received by each of the devices.

摘要： The present invention provides a means and an apparatus for watermarking a digital signal. A particular content which is to be made available by a content provider to potential content users is prepared by encoding the content into a plurality of encoded streams, each encoded stream being encoded according to a different bit-rate. Each encoded stream comprises a plurality of chunks and each chunk is retrievable by a requestor of content. Upon request of said content by a user, the plurality of chunks making up the content are selected from the plurality of the different encoded streams and a subset from that plurality of chunks is watermarked using a unique identifying parameter associated with the requestor.

摘要： Disclosed is an image projector of the type in which an LCD matrix screen is illuminated by two polarized beams after 90.degree. rotation of the direction of polarization of one of these two beams. Each of the two polarized beams is reflected at least once towards an optical axis on which the matrix screen is centered and at least once again towards the matrix screen. Furthermore, the image projector has means to make each beam polarized, so that each polarized beam forms an image of the light source before illuminating the matrix screen. The two polarized beams may thus be oriented towards the matrix screen in forming a small angle with one another, thus enabling the use of a projection objective with a small aperture.
摘要翻译：公开了一种这种类型的图像投影仪，其中在这两个光束之一的偏振方向90度旋转之后，LCD矩阵屏幕被两个偏振光束照射。两个偏振光束中的每一个至少一次朝向矩阵屏幕中心的光轴反射，并且至少再次朝向矩阵屏幕反射。此外，图像投影仪具有使每个光束偏振的装置，使得每个偏振光束在照射矩阵屏幕之前形成光源的图像。因此，两个偏振光束可以朝着矩形屏幕定向成彼此形成小角度，从而能够使用具有小孔径的投影物镜。
