The method includes detecting a first modification of a characteristic of the radio wave, the first modification being resultant from a start of the gesture, and detecting a second modification of a characteristic of the radio wave, the second modification being resultant from an end of the gesture, where the acquisition of a right for the user is dependent on the first modification and the second modification. ## Claims ### Claim 1 A method for receiving a near-field radio wave, the wave being received using electromagnetic-wave conduction capacities of the body of a user able to make a validation gesture that modifies characteristics of the radio wave, the radio wave comprising frames, the method comprising detecting a first modification of a characteristic of the radio wave, the first modification being resultant from a start of the validation gesture; detecting a second modification of a characteristic of the radio wave, the second modification being resultant from an end of the gesture, the acquisition of a right for the user being dependent on the first modification and the second modification, a lifetime of the right being directly linked to a duration of the validation gesture; extracting, from a frame of the radio wave, a random factor time-variable verification code allowing a timestamp to be deduced; and sending, to a server that manages the right, a detection message relating to at least one detection, wherein the detection message comprises the random factor time-variable verification code, allowing a timestamp to be deduced. ### Claim 2 (depends on 1) The method of claim 1, the method further comprising extracting, from a frame of the radio wave, an identifier of a device which sent the near-field radio wave, wherein the detection message relates to at least one detection comprising said identifier in addition to the random factor time-variable verification code. ### Claim 3 (depends on 2) The method of claim 2, wherein the detection message comprises a datum relating to the user in addition to the random factor time-variable verification code and in addition to the identifier of the device. ### Claim 4 (depends on 2) The method of claim 2, further comprising sending a plurality of successive detection messages up to the detection of the second modification, a first message of the plurality of successive detection messages being sent as soon as the first modification is detected. ### Claim 5 (depends on 2) The method of claim 2, wherein, before a datum is extracted from a frame, sending a return message indicative of the detection of the validation gesture to the device which sent the near-field radio wave. ### Claim 6 (depends on 1) A computer comprising a processor and a memory, the memory having stored thereon instructions which, when executed by the processor, cause the computer to implement the method of claim 1. ### Claim 7 (depends on 1) A non-transitory, computer-readable storage medium having stored thereon instructions which, when executed by a processor, cause the processor to implement the method of claim 1. ### Claim 8 (depends on 1) The method of claim 1, wherein a duration of the acquired right is dependent upon a duration of the validation gesture. ### Claim 9 A device configured to receive a near-field radio wave using electromagnetic-wave conduction capacities of the body of a user, the user able to make a validation gesture that modifies characteristics of the radio wave, the radio wave comprising frames the device comprising a detection circuit, a processor, and a memory coupled to the processor, the memory containing instructions that are intended to be executed by the processor in order to: detect a first modification of a characteristic of the radio wave, the first modification being resultant from a start of the gesture; detect a second modification of a characteristic of the radio wave, the second modification being resultant from an end of the gesture, the acquisition of a right for the user being dependent on the detections of the first and second modifications, a lifetime of the right being directly linked to a duration of the validation gesture; extract, from a frame of the radio wave, a random factor time-variable verification code allowing a timestamp to be deduced; and, send, to a server that manages the right, a detection message relating to at least one detection, wherein the detection message comprises the random factor time-variable verification code, allowing a timestamp to be deduced. ### Claim 10 (depends on 9) A system for acquiring a temporary right, the system comprising: the receiving device of claim 9; a sending device configured to emit a near-field radio wave; and a rights-managing device configured to attribute a right dependent upon at least one datum relating to the start of the validation gesture and to the end of the validation gesture, a lifetime of the right being directly linked to a duration of the validation gesture. ### Claim 11 (depends on 10) The system of claim 10, wherein: the sending device is configured to detect a physical contact with the user; and the rights-managing device is configured to attribute the right dependent upon a datum relating to physical contact. ### Claim 12 (depends on 10) The system of claim 10, wherein: the sending device is further configured to insert, inter the near-field radio wave, a random factor known the to the rights-managing device; and the receiving device is further configured to: extract the random factor, and transmit the random factor to the rights-managing device. ### Claim 13 (depends on 10) The system of claim 10, wherein the sending device is configured to: detect a physical contact with the user; and insert, into the near-field radio wave, a random factor known the to the rights-managing device, the inserting means being activated after detection of the physical contact with the user. ### Claim 14 (depends on 9) The system of claim 9, wherein a duration of the acquired right is dependent upon a duration of the validation gesture.
