    摘要: The present invention refers to a method for scrambling an original digital image (10) into a scrambled image (20) and for descrambling the scrambled image (20) into a reconstructed image (30). In accordance with a certain coding format, the original image (10) is defined by a set of orderly original coefficients (12, 13). These coefficients refer to coding elements arranged in blocks (11) within this image, and/or to parameters of said coding format within a conversion table. The method comprising: a scrambling operation comprising the steps of: - substituting a plurality of the original coefficients (12, 13) by dummy coefficients (12', 13') of the same nature so as to safeguard said coding format, - storing the substituted original coefficients (12, 13) with their respective position, as original data (15) into at least two control objects (CO1, CO2), each control object corresponding to a specific degradation level of the original image (10); and a descrambling operation comprising the steps of: - receiving the scrambled image (20) and at least a part of said control objects (CO1, CO2), - using original data (15) derived from a selection of at least one of said control objects (CO1, CO2), performed on the basis of a user access condition (25), for obtaining the reconstructed image (30) by putting back the original coefficients (12, 13) instead of said dummy coefficients, thanks to their respective position.

    摘要: The present invention relates to a method of privacy-preserving during an access to a restricted e-service requiring user private data from a smart card. The invention relates more particularly to the field of methods implemented so that the user has the guarantee that only the private data needed to access to the e-service are extracted from the smart card. It is to guarantee that the user has a perfect knowledge of his private data provided by his smart card to a requester. With the invention a message notifying to the user the very nature of the identity assertion is displayed on the screen of the smart card. By doing so, the card ensure 100% security with regard to user consent: the data read out of his card cannot differ comparing to the data requested by the service provider through the terminal.

    摘要: A communication module 6 of a communication terminal 2 is configured not to output to a control module 5, service information provided from a second server 4 whose server ID is not registered in a first server 3. The communication module 6 is configured to receive an authentication code from the first server 3, and to transmit ID information and terminal identification information to the second server 4. When the terminal identification information received from the communication module 6 matches the terminal identification information received from the first server 3, the second server 4 is configured to reply the authentication code and the service information to the communication module 6. When the authentication code received from the first server 3 matches the authentication code received from the second server 4, the communication module 6 is configured to output the service information to the control module 5.

    摘要: A method for encrypting a 3D object. In a preferred embodiment, the encryption shapes the 3D object by generating (S21) a set of secret functions using a secret K, applying (S22) the generated functions to the 3D object, determining (S23) the function that gives an output that is closest to predetermined characteristics, encrypting (S24) the 3D object using the determined function, and outputting (S25) the encrypted 3D object and an indication of the determined function. Also provided is a corresponding decryption method, an encryption device (910) and a decryption device (940).

    摘要: The graphical characteristics of 3D graphical objects encrypted using format-preserving encryption makes rendering of such objects quite inefficient by non-authorized devices. To optimise the rendering of a three-dimensional graphical object (120) represented by a list of points and a list of surfaces defined by points in the list of points, a device (110) receives (210) the graphical object (120); encrypts (220) the graphical object (120) using a format-preserving encryption method to obtain an encrypted graphical object; encapsulates the encrypted graphical object to obtain an encapsulated graphical object by adding at least one encapsulation by adding for each encapsulation, to the list of surfaces, a plurality of surfaces that together enclose the encrypted graphical object and, in an embodiment, at least one point to the list of points; and outputs (230) the encapsulated graphical object (130). Decryption is performed by essentially reversing the encryption.
