Abstract: Systems and techniques are described herein for determining latencies between user devices, ordering or grouping the user devices according to those determined latencies, and then streaming audio to the user devices where the audio stream is played using speakers, and at the same time vocalizations of the user as they sing along to the received stream are captures, and combined with vocalizations of other users to create a final combined audio file.

Abstract: A method for securing a communication between a remote server and a device equipped with a secure element, device side profile data being stored in the device, and device side secure element data being stored in the secure element. The image data includes server side profile data being stored in the remote server, server side secure element data being stored in the remote server, or being retrievable from the remote server. The method includes associating the device with the secure element, generating, on the device side, a device key material, reporting the association to the remote server, generating, on the remote server side, a server key material, authorizing a communication between the device and the remote server, after an authentication based at least on the basis of a comparison between the device key material and the server key material.

Abstract: The disclosure relates to a method for enabling the secure functions of a chipset (1) and especially the encryption of the content of the secure memory (7) when the device goes into low power mode. The content of the secure memory (7) may be encrypted and stored in an external memory (20) during low power mode of the chipset (1).

Abstract: In overview, methods, computer programs products and devices for securing software are provided. In accordance with the disclosure, a method may comprise attaching a debugger process to a software process. During execution of the software process, operations relevant to the functionality of the code process are carried out within the debugger process. As a result, the debugger process cannot be replaced or subverted without impinging on the functionality of the software process. The software process can therefore be protected from inspection by modified or malicious debugging techniques.

Abstract: A method for securely receiving a multimedia content by a client device operated by one or more operator(s) involving a dedicated provisioning server of a security provider managing symmetric secrets used by the client devices and operators license servers. The provisioning server provides to the client device one or more generations of operator specific unique device secrets, which are then exploited by the various operators' license servers to deliver licenses such that authorized client devices can consume protected multimedia contents.

Abstract: The present disclosure generally relates to code verification. For example, aspects of the present disclosure include systems and techniques for determining whether two codes are a match. One example method generally includes generating, at a first device, first encrypted data at least in part by encrypting verification data using a public key; generating, at the first device, second encrypted data at least in part by encrypting a random factor using the public key; generating, at the first device, a key for the verification data; generating, at the first device, third encrypted data at least in part by encrypting the key using the public key; computing, at the first device, fourth encrypted data at least in part by applying homomorphic encryption function to the first encrypted data, the second encrypted data, and the third encrypted data; and sending, to a second device, the fourth encrypted data.

Abstract: Method for providing at least one client device (10), from a server (20) configured to control access to audio/video content, with management messages (40), comprising:—determining a first set (41) of management messages pertaining to said client device (10),—transmitting said first set through a first communicatio n channel (51) in a repetitive manner,—receiving, from said client device, a notification (15) comprising at least a client device identifier (11),—determining a second set (42) of management messages, said second set comprising all or part of the first set,—determining a token (45) associated with the second set,—receiving, from the client device, a confirmation (15?) comprising data pertaining to the token,—verifying the data pertaining to the token and, in case of a positive verification, removing all or part of the second set from the transmission through the first communication channel.

Abstract: A method for detecting perturbations in a logic circuit including a plurality of datapaths coordinated by a clock signal and at least one test circuit having a programmable length datapath for varying a test propagation delay. The test circuit further including inputs, an output and an error generator for providing an error in case that the output is different than an expected output for the inputs. The test circuit having a calibration mode including determining a critical propagation delay by varying the programmable length datapath until the error generator outputs an error, adjusting the programmable length datapath to include therein a tolerance delay, and switching into a detection mode configured to detect a perturbation in the logic circuit along the programmable length datapath in case the error generator outputs an error.

Abstract: A method of programming a device comprising acquiring configuration data, loading the configuration data onto a programmable device, processing at least a portion of the configuration data through a one way function to form processed configuration data, and configuring at least one configurable module of the programmable device using the processed configuration data from the processing step.

Abstract: An internet of things is disclosed, comprising plural SDR receivers and possibly a centralised system, where one or more of the receivers may be mobile. The internet of things thus allows for a very large proportion of RF signals present within a city, for example, to be monitored and analysed for the purpose of identifying, tracking and/or preventing criminal behaviour. The receivers may be equipped with secure SDRs for increased security and privacy and the system preferably includes artificial intelligence using machine learning technology, for increased adaptability among others. The system is flexible due to the programmability of the SDRs.

Abstract: A post-processing of video content in order to provide a capability to insert ad content, having a method to produce a modified video content from an original video content. The method comprising: analyzing the original video content to detect at least one marker, said marker comprising a marker surface delimited by a marker identification; loading profile data of a target user; determining, based at least on the profile data a replacement content; adjusting the replacement content into the marker surface; and replacing into the original video content the marker surface by the adjusted replacement content to produce the modified video content.

Abstract: The method of proximity detection between a first and a second device (DVC1, DVC2), carried out by the first device (DVC1), comprises the steps of collecting a first information on exposure of the first device (DVC1) to electromagnetic waves; receiving a second information on exposure of the second device (DVC2) to electromagnetic waves from the second device (DVC2); determining a matching information between the first information on exposure and the second information on exposure and detecting either proximity or non-proximity between the first and the second device (DVC1, DVC2) based on the matching information.
