Abstract: This invention relates to a method for updating a one-time secret key Kn maintained in a subscription module implemented in a communication apparatus, a wireless communication network maintaining an identical version of said one-time secret key Kn and configured to determine a result XRES expected from the communication apparatus when an authentication function is applied by the subscription module using a random challenge and said one-time secret key Kn as an input, the method comprising the following steps: receiving from the communication network an authentication request message containing at least a random challenge RANDn; determining by the subscription module a result RES by applying the authentication function using the random number RANDn and the one- time secret key Kn as inputs; transmitting said result RES to the communication network for it to be compared with the expected result XRES determined by the communication network using the random number RANDn and the corresponding version of the one-time secret key Kn, the subscriber being authenticated if said first and second results are matching; updating the one-time secret key Kn by replacing its current version with a new version obtained by applying a first key derivation function using the random challenge RANDn as an input, the updated version of the one-time secret key Kn being used by the subscription module for processing a subsequent authentication request, the same update being carried out by a server accessible or part of the wireless communication network in order to maintain an identical version of the one-time secret key Kn.

Abstract: The present invention relates generally a method to authenticate a data carrier, such as passports, licenses, identification card…by hiding at least two optically encoded image within a data carrier so that the data carrier is authenticated through at least two factor authentication process. In the methods of the present invention, at least two reliable, readable optically encoded image are hidden within the data carrier wherein each of the encoded image is visible through a same decoder device but under different specific lighting conditions without the former having influence on the quality of the latter. The authentication methodology of the present invention provides an improved security, being even more difficult to reproduce by infringers, even more difficult to remove, replace or exchange and easy to check.

Abstract: The invention relates to a method (20) for authenticating a user. A server (14) accesses a user identifier associated with a second user device (16) identifier. The server accesses, for the user, a predetermined reference location(s) within a reference table. The method comprises: Sending from a first user device (12) to the server, through a first communication channel, a message (24) including the user identifier and a request to get a challenge table. Generating (26), by the server, a first challenge table including a valid first set of characters. Sending, thanks to the second user device identifier, from the server to the second user device, through a second communication channel, a message (210) including the first challenge table and a first request to display the first challenge table. Displaying (212), by or through the second user device, the first challenge table. Selecting (216), by a user, through a first user device man machine interface, a a selected character(s). Sending, from the first user device to the server, through the first communication channel, a message (220) including the selected character(s), as submitted user authentication data. Determining (224), by the server, based upon the predetermined reference location(s) within the first challenge table a corresponding reference character(s), as reference user authentication data. Verifying (226), by the server, for the user, whether the submitted user authentication data does or does not match the reference user authentication data. And, only if yes, succeeding, by the server, in authenticating the user. The invention also relates to corresponding user devices (12) and (16), server (14) and system (10).

Abstract: This invention relates to a method for provisioning a wireless control device (115) with an information element allowing to identify visually at least one unauthorized user in a restricted area, the restricted area comprising a gateless control area being equipped with at least an image sensor (112) and an electronic reader (113) supporting a short range radio technology allowing to read data memorized into a wearable device (111) carried by a user (110). The method comprises the steps of: providing (120, 121) by the image sensor a digital image of at least one user that is detected as passing through the gateless control area; extracting from the provided digital image of the detected user a first face detection dataset; providing (122, 123) by the electronic reader a second face detection dataset memorized in a wearable device carried by said detected user; applying (130) facial recognition over the first and second face detection datasets in order to determine if the user associated to the first face detection dataset is the same as the one associated to the second face detection dataset, the detected user being identified as authorized in that case and identified as unauthorized otherwise; sending (126) to a wireless control device a message comprising an information item adapted to ease the visual identification of an unauthorized user.

Abstract: The invention relates to a method (20) for authenticating a first user. A device (12) accesses a sequence (20) of at least one reference graphical item, as a reference graphical item sequence. The reference graphical item sequence is known only to the first user. The method comprises the following steps. The (or another cooperating) device requests a user to point consecutively at at least one area in which at least one graphical item is included. The (or another cooperating) device (presents (410) a sequence of at least one graphical item. The (or another cooperating) device captures (414) a sequence of at least one area pointed by the userby detecting at least one predetermined change relating to at least one physical user feature to validate each or at least one user pointed area. The (or another cooperating) device verifies (418) whether the sequence of the at least one user pointed area does or does not include the reference graphical item sequence. And the (or another cooperating) device authenticates (420) the first user only if the sequence of the at least one user pointed area includes the reference graphical item sequence. The invention also relates to corresponding device and system.
