A method for secure pairing between a sensor and a concentrator using a mobile terminal includes generating and emitting a confirmation code by the concentrator; converting by the sensor of the confirmation code into a sequence of light signals executed by at least one light-emitting diode; converting by the mobile terminal of the sequence of light signals into a sequence code; sending the sequence code to the concentrator; comparing, by the concentrator, the sequence code and the generated confirmation code: if the sequence code does not match the generated confirmation code, generating a warning; if the sequence code matches the generated confirmation code, pairing and exchanging information between the sensor and the concentrator.

The invention relates to an electronic transaction method for a system comprising a user-associated payment device 3 or 4 and a payment terminal 1. The payment device 3 or 4 and the payment terminal 1 perform a cryptographic key exchange 500 before performing a transaction step 501. The payment device includes personal information PI about the user. The payment terminal includes a transaction policy including a condition relative to the personal information Pi. The method includes a verification step 510, 520, 530, prior to the transaction step 501, for securely verifying the condition of the transaction policy relative to the personal information using the cryptographic key.

A Bluetooth communication method implemented between first and second electronic devices, including establishing a communication in a connected mode between the first and second devices including a key exchange operation between these two devices, and establishing a communication in an advertising mode between the first and second devices including a periodic broadcast by the second device to the first device of a message including a payload and a calculated tag from this key.

Various embodiments of the present technology generally relate to data delivery. More specifically, some embodiments of the present technology relate to systems and methods for using spatial and temporal analysis to associate data sources with mobile devices. The delivery of data to support a wide variety of services for and about mobile devices that are based on data stored in corporate, commercial, and government databases which is not currently linked to individual mobile devices. Some embodiments allow advertisers to better target their ads to relevant target audience with greater accuracy.
