Abstract: A method of creating lottery tickets of which the possible prize will be discovered by the holder of same via a Smartphone application which, depending on the image on the ticket, will make it possible to reach, on a remote computer site, the equivalent of a draw, that is preferably pre-recorded or pre-defined and will be displayed on the Smartphone in a form equivalent to a video, thus making it possible for the holder to be able to follow and experience the draw and thus find out if he has won and, in this case, what the prize is. The distribution of the prizes, the guarantee that the draw is unique and the “new” nature of the tickets are guaranteed and managed by the remote computer system. The method makes it possible, in particular, to bring a novel appeal to lotteries based on scratchcard tickets, which are the main key to the success of this kind of lottery.

Abstract: A method for watermarking a document containing at least one text portion comprising the following steps: —determining a specific character font comprising, for at least one character, an original graphic and at least one variation, each of the variations being associated with a different value, said character being termed encodable characters; —using the specific character font to encode an item of information in the text portion of the document, by replacing at least one original graphic with a variation, the original graphic and the variation or variations being identified as a single character by a first optical character recognition process referred to as standard OCR and identified as a plurality of characters by a second optical character recognition process referred to as specific OCR that is capable of determining if the represented character is the original graphic or one of the variations of same and, if so, making it possible to determine the variation that is represented, a strict order relations

Abstract: A method for authenticating a document comprising the following steps: when creating an original document, said document is sent by a holding entity to an authentication management entity in order for said document to be stored at a secure storage site and for any delivery of an authenticated copy and/or authenticatable copy to be managed by the authentication management entity, when a request for an authenticated copy is made by a requesting entity, the holding entity makes a duplication request via a suitable duplication system controlled by the authentication management entity in order to obtain an authenticatable transmission copy, the requesting entity uses the authenticatable transmission copy to make a duplication request via a suitable duplication system in order to obtain an authenticated copy delivered under the control of the authentication management entity.

Abstract: A method and device for securely duplicating sensitive documents. A marking element is entered on the original document to identify its confidential nature, as well as an encoded rules elements which defines duplication restrictions of the document. For each duplication request (101) for a sensitive document (102), the document is digitized (103) to determine the presence of a marking element (104) and to find the duplication restrictions, i.e., the encoded rules elements (106). Duplication may be performed (110) depending on the restrictions defined in the rules elements (106) and after an authorization check (108). A duplication may be obtained by requesting the computerized original of the document from the document issuer. In addition to the selective control of reproduction of documents the method and device is particularly suitable for preventing the duplication of documents for fraudulent purposes, multiple duplication of selected documents, and for copyright administration.
