20130067554 | METHODS, DEVICES AND COMPUTER PROGRAM SUPPORTS FOR PASSWORD GENERATION AND VERIFICATION - During log-on of a user to an entity protected by a password, the password is verified by iteratively receiving a password character; and verifying that the received character complies with a predefined property (α) that sets at least one requirement for allowable passwords. If this is not the case, then this can indicate a brute force attack and appropriate action may be taken. The property α may be dependent on the user. Also provided are a corresponding device and a computer program product. | 03-14-2013 |
20130305380 | METHODS AND DEVICES FOR 3D OBJECT PROTECTION USING SURFACE SUBDIVISION - A method of protecting a graphical object represented by a list of vertices and a list of surfaces, each surface being defined by a number N vertices. A device selects a surface S with N vertices; computes a new vertex d using a random or pseudo-random function; inserts the new vertex d into the list of vertices; creates N new surfaces S | 11-14-2013 |
20140115345 | METHODS AND DEVICES FOR OPTIMISING RENDERING OF AN ENCRYPTED 3D GRAPHICAL OBJECT - 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 represented by a list of points and a list of surfaces defined by points in the list of points, a device receives the graphical object; encrypts the graphical object 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 the encapsulated graphical object. Decryption is performed by essentially reversing the encryption. | 04-24-2014 |
20140119538 | METHOD AND DEVICE FOR 3D OBJECT ENCRYPTION BY APPLICATION OF A FUNCTION MODIFIED USING A SECRET KEY - A method for encrypting a 3D object. In a preferred embodiment, the encryption shapes the 3D object by generating a set of secret functions using a secret K, applying the generated functions to the 3D object, determining the function that gives an output that is closest to predetermined characteristics, encrypting the 3D object using the determined function, and outputting the encrypted 3D object and an indication of the determined function. Also provided is a corresponding decryption method, an encryption device and a decryption device. | 05-01-2014 |
20140317705 | APPARATUS AND METHOD FOR MANAGING PASSWORDS - A method for managing passwords for a user. A processor of an apparatus storing at least one received, incorrect password proposal receives via a user interface a further password proposal from a user; generates a hash value for the further password proposal; sends the hash value to the authentication server; receives from the authentication server a message indicative of whether the hash value corresponds to a correct password or to an incorrect password. In case the message indicates that the hash value corresponds to a correct password, the processor uses a distance function on each incorrect password proposal to obtain a distance value representative of a distance between the incorrect password proposal and the correct password; and sending to the authentication server hash values for password proposals for which the distance value is lower than or equal to a threshold value. Also provided are the apparatus and a computer program support. The disclosure can provide resistance to typing errors in the password proposals. | 10-23-2014 |
20150081760 | METHOD AND DEVICE FOR PROVIDING ACCESS TO A TASK - In a collaborative work environment, a participant chooses a task to perform and the identifier of the task is sent from a participant device to a first server. The first server creates a Virtual Machine that is configured with a dedicated tool and appropriate data, instantiates the Virtual Machine on a second server, and sends connection information to the participant device. Using the connection information, the participant device connects to the Virtual Machine on the second server and works on the task. It is preferred that remote desktop technology is used so that the participant works through a remote desktop client on the participant device, while the work in effect is done on the second server. The disclosure can thus, at least to a certain extent, ensure that a specified participant uses a dedicated tool to work on data to be treated by the task. | 03-19-2015 |
20150302067 | AN ASSET HANDLING TOOL FOR FILM PRE-PRODUCTION - An asset handling tool for pre-production of a film having a script configured to: obtain a search expression from a scene of the script; send to an asset database a query for assets corresponding to the search expression; receive a set of assets matching the search expression; display at least part of the set of assets to a user; receive, from the user, a selection of an asset in the set of assets; and link the selected asset with the scene. The asset handling tool is advantageously implemented in a tool for collaborative pre-preproduction of the film and can help a director or a producer to pre-produce the film by suggesting already made assets that can be imported into the film, possibly after treatment. | 10-22-2015 |
20150317571 | DEVICE FOR FILM PRE-PRODUCTION - A system for collaborative pre-production of a film comprises user interfaces advantageously implemented as web browsers, a project server, a project database for storing project data and an asset database for storing tagged assets. The project server comprises a project management module providing the framework for the system, a data access module enabling users to view data, and a pre-visualization module for providing a best effort preview of the film based on the script and associated direction choices and assets. The project server can also comprise an asset recommendation module for suggesting, based on key words, assets in the asset database for scenes of the film, a direction assistant module for suggesting direction possibilities, including cost and delay estimates, for the scenes. | 11-05-2015 |
