摘要： A device (100) that is configured to generate reports to send to a server comprises at least one processor (111) configured to generate the reports. Upon loss of connection, generated reports are stored in a buffer (1121) in memory (112) of the device (100), capable of storing k reports. The first generated report is stored in a first part of the buffer (1121), a most recently generated report is stored in a second part of the buffer, while the remaining reports are stored in a third part of the buffer. When the third part is full, a sampling algorithm is used to select the k-2 reports to store in the third part.

摘要： Method for providing targeted content in image frames of a video and corresponding device A scalable and flexible solution for targeting a video through overlaying image frame zones with content that is targeted to individual users according to user preferences is provided. A video sequence is processed to determine sequences of image frames that comprise overlayable zones for overlay with targeted content. Features that describe these frames and these zones for a content overlay operation are stored in metadata that is associated to the unmodified video sequence. When the video is transmitted to a user, the metadata is used to overlay content in the overlayable zones, whereby the content is chosen according to the preferences of the user.

摘要： The invention relate to a method for fingerprinting at least one network device comprising, in a monitoring device, a step of computing a passive fingerprint from a plurality of parameters of the at least one network device. The method being remarkable in that it comprises a step of modifying at least one parameter among the plurality of parameters of the at least one remote networked device, wherein the parameters modification is derived from a function over the time called diversity function, the modified parameters result in a variation of the passive fingerprint of the at least one network device in order to increase the fingerprint diversity, and wherein said variation of the passive fingerprint is limited to a determined range in order to preserve the fingerprint stability. The invention is particularly suitable for IEEE 802.11 and for a fingerprinting method based on inter-arrival time histogram.

摘要： A method for detecting interferences in wireless networks is disclosed. A salient idea is to use a first access point for detecting an interference disturbing a wireless device associated with a second access point, wherein the device at the origin of the interference is in the range of the first access point, but not in the range of the second access point. Leveraging on the difference of coverage between different wireless networking technologies, the first access point is capable of detecting both a data traffic of a second access point and a short range interfering device in a same frequency channel. More precisely, by measuring a level of strength of a signal received in the frequency channel at a period of time where no data traffic of the second access point is detected, the first access point is capable of detecting an interference according to the measured signal. The detected interference corresponds to another device using the frequency channel of the second access point, without communicating with the second access point. As the interference detected by the first access point may not be detectable by the second access point (because not being in the range of the second access point although disturbing some of its associated devices), the first access point advantageously sends an information item indicating the interference has been detected. Sending such indication is advantageous as it allows the second access point to detect an interfering device, even if not being in its range.

摘要： The invention relates to a method for controlling access to a first network, comprising receiving, by a first network access device of the first network, an access request from a first user device, determining, by the first network access device, if the first user device was granted an access to the first network, if the first device has not been granted an access to the first network, determining if there is a second network access device that granted the first user device an access to a second network and the second network access device is linked to the first network access device, and if the second network access device exists, granting the first user device an access to the first network by the first network access device.

摘要： A device (100) and a method for password generation. When password generation is triggered (S20), a processor (110) of the device (100) applies (S21) a function to constant and non-constant parameters in or around the device (100) to obtain a value from which the password is generated (S22). A password authentication value is generated (S23) from the password and stored, and the password is encrypted using a public key (S24) and stored. The password is displayed (S25) on a persistent electronic display (150) on which information rests even without power supply. The processor (110) finally deletes (S26) the generated password so that it is only displayed on the display (150).
