Patent number: 11341244Abstract: Method and device for detecting encryption, in particular for anti-ransomeware software. The invention relates to a device for detecting encryption, comprising a computer (1) with a central processing unit (4) and a memory, which comprises a random-access memory (9) and a mass memory unit (6) comprising files. The central processing unit (4) cooperates with the random-access memory (9) and with an operating system (10) which comprises a core (12) and which is capable of having processes (18) carried out by the central processing unit (4); said processes (18) are divided into wires (20) and may comprise functions for accessing the files. A statistical model for ordinary writing to the header of a file is stored in the memory (6, 9).Type: GrantFiled: January 16, 2019Date of Patent: May 24, 2022Assignees: INRIA INSTITUT NATIONAL DE RECHERCHE EN INFORMATIQ, ÉTAT FRANÇAIS, REPRÉSENTÉ PAR LE DÉLÉGUÉ GÉNÉRAL PInventors: Aurélien Palisse, Jean-Louis Lanet, Colas Le Guernic, David Lubicz

Patent number: 9329258Abstract: Method for locating, in a fixed frame of reference (RG), a moving craft from the craft, comprising two characteristic points, the rolling and pitching of the craft in the fixed frame of reference having been determined, so as to determine the yawing and/or the coordinates of the craft in the fixed frame of reference: a/ a local frame of reference (Rn) comprising an axis deviating from the yaw axis of the fixed frame of reference by a known angle resulting from a rotation about a first axis of the first local frame of reference dependent on the roll (R) and a rotation dependent on the pitch (P) is defined; b/ the coordinates of each characteristic point (P1, P2) in said local frame of reference being equal, to within an unknown common factor, to the multiplying of a matrix defining said succession of rotations by a matrix of intrinsic image capture parameters and by the coordinates of a pixel corresponding to the characteristic point in an image captured from the craft, the values adopted by the quotients relaType: GrantFiled: November 19, 2013Date of Patent: May 3, 2016Assignee: Inria Institut National De Recherche En InformatiqInventors: Stefano Al Zanati, Chiara Troiani, Agostino Martinelli

Publication number: 20130091180Abstract: A tool for assisting the operation of a network of interconnected physical equipment includes a physical infrastructure manager associated with a first data structure in which the equipment items are registered under a resource identifier in relation to a first sequence of dated values of global utilizable functional capacity, and a virtual infrastructure manager associated with a second data structure in which virtual units are registered under a unit identifier in relation to a second sequence of dated values of global utilizable functional capacity, and with a third data structure in which a virtual unit identifier is associated with a group of resource identifiers and hence with the corresponding sequences of dated capacity values. The virtual infrastructure manager dynamically reconfigures a virtual infrastructure object in accordance with the rights and capacities requested by a user.Type: ApplicationFiled: April 14, 2011Publication date: April 11, 2013Applicant: Inria Institut National de Recherche en Informatiq et en AutomatiqueInventors: Pascale Vicat-Blanc-Primet, Sebastien Soudan, Guilherme Koslovski

Publication number: 20120087559Abstract: The invention relates to a device and to a method for cerebral location assistance. The device includes first and second memories. The first one is adapted for storing a generic mapping of the brain according to a first space location mode, as well as designation data corresponding to a target area in said mapping. The second one can receive and store, according to a second pace location mode, an operation image of the brain of an analysed subject acquired by medical imaging. The device also includes a non-rigid resetting tool adapted for establishing a conversion of the generic three-dimensional mapping towards the operation image, and a resampling tool for establishing a converted mapping with the converted designation data. A user's interface defines a visualization image that matches the operation image and the converted mapping while indicating an area that corresponds to the converted designation data.Type: ApplicationFiled: January 15, 2010Publication date: April 12, 2012Applicant: INRIA INSTITUT NATIONAL DE RECHERCHE EN INFORMATIQ ET EN AUTOMATIQUEInventors: Pierre Hellier, Xavier Morandi, Cecilia Naucziciel
