Abstract: A device accesses a reference graphical item sequence. The reference graphical item sequence is known only to the first user. The device requests a user to point consecutively to at least one area in which at least one graphical item is included. The device presents a sequence of at least one graphical item. The device captures a sequence of at least one area pointed to by the user by detecting at least one predetermined change relating to at least one physical user feature to validate at least one user pointed area. The device verifies whether the sequence of the at least one user pointed area includes the reference graphical item sequence. The device authenticates the user only if the sequence of the at least one user pointed area includes the reference graphical item sequence.

Abstract: The present invention relates to a method to secure an applicative function in a cloud-based virtual secure element implementation, said virtual secure element being intended to be used by a dedicated emulated secure element application to perform said applicative function, said implementation being supported by a user device comprising the emulated secure element application and a local secure element comprising a Public Key Infrastructure applet and by a cloud remote server having an emulated virtual secure element corresponding to the user of the user device, said user device and cloud remote server further respectively having a secure cloud library and a secure cloud front-end.

Abstract: A slave wireless device includes several applications, a wireless communication interface and a processing module. The processing module interprets a presentation request and time-slotted markers received on the communication interface, selects several applications or application groups corresponding to the presentation request, and transmits the wireless slave device identifier distinctive for each application or application group selected in the distinctive time slot in response to the presentation request. The slave device is thus enabled to indicate several application groups in response to a single presentation request.

Abstract: The invention relates to a slave wireless device (Picc) comprising: several applications, a wireless communication interface, a processing module interpreting a presentation request (ReqB4SM00) and time-slotted markers (ReqB4SM00, SM2, SM3, SM4) received on the communication interface, selecting several applications or application groups corresponding to the presentation request (ReqB4SM00), transmitting the wireless slave device identifier distinctive for each application or application group selected in the distinctive time slot in response to the presentation request. Said invention enables the slave device to indicate several application groups in response to a single presentation request.
