Abstract: A system for ordering a product online includes a communicating object configured to order a set of products referenced in a database by means of an order signal (CMD), and a database for listing a set of products corresponding to the order signal (CMD). A server is in communication with said database and is configured to publish a list of said set of ordered products. A computer likely to validate said list such that the communicating object may be a mobile device provided with a processor, a random access memory (RAM) and a hibernation software program such that the processor is stopped and the content of the random access memory (RAM) is not kept when said communicating object has not been used for a predefined period, or depending on the status of the communicating object.

Abstract: A method for authorizing an action via authentication of a user for a device comprising sensors and emitters, a processor, and a memory. The method comprises: requesting the processor perform an action, verifying the level of authentication required by the user for performing the action, adjusting the user's level of authentication when the level of authentication is insufficient, authorizing the action, wherein adjusting the user's level of authentication comprises: emitting at least one random or non-random sequence of stimuli to the user, capturing behavioral biometric data on the user's reactions to the emitted stimuli, by recording the actuated sensor(s) and the type of action performed on the sensor provided by the received signal, validating the user's response by comparing the reaction performed by the user on the basis of the response to the stimuli previously recorded in the memory, with an expected response allowing validation of user authentication.
