Process for declaring the non-usability of exchanged data
A method of making secure a communication between a first and at least one second terminal is disclosed. Each terminal being configured to interact with a user via a corresponding human-machine interface, the method comprising selecting, on the first terminal, a usability index for signals in a stream; transmitting the stream from the first terminal to at least one node of a network; connecting a third-party device to the node according to the usability index; and receiving, on the at least one second terminal, the stream from the node.
1. A method of making secure a communication between a first terminal and at least one second terminal, the method comprising:
selecting, on the first terminal, a usability index for signals in a stream;
transmitting the stream from the first terminal to at least one node of a network;
connecting a third-party device to the at least one node according to the usability index; and
receiving, on the at least one second terminal, the stream from the at least one node; and
wherein each of the first terminal and at least one second terminal is configured to interact with a user via a corresponding human-machine interface.
2. The method according to claim 1 , wherein the connection comprises a denial of access by the third-party device to the signals if the usability index is a denial attribute.
3. The method according to claim 1 , wherein the connection comprises an authorization for the third-party device to read the signals if the usability index is a processing attribute.
4. The method according to claim 1 , wherein the connection comprises an authorization for the third-party device to post-process signals if the usability index is a post-processing attribute.
5. The method according to claim 1 , wherein the usability index is comprised in a transmission initiation message, the message being sent by the first terminal after the selection and before the transmission.
6. The method according to claim 1 , wherein the communication is implemented via a communication protocol selected among: an RCS protocol, an SDP protocol, an RTSP protocol, an MSRP protocol, and/or a SIP protocol.
7. The method according to claim 1 , wherein the connection comprises a modification of the usability index by the first terminal.
8. The method according to claim 1 , wherein at least one signal of the signals in the stream is a type of signal on which the usability index depends, and is selected among: a text signal, an audio signal, a visual signal, and/or an audiovisual signal.
9. The method according to claim 1 , wherein the third-party device is at least a third terminal configured to interact with a corresponding user via a human-machine interface.
10. A communication system configured to make a communication secure between a first terminal and at least one second terminal, the system comprising:
the first terminal, comprising a selection module for selecting a usability index for signals in a stream and comprising a transmission module for transmitting the stream to at least one node of a network;
a connection module for connecting the at least one node to a third-party device according to the usability index; and
the at least one second terminal, comprising a reception module for receiving the stream from the at least one node; and
wherein each of the first terminal and at least one second terminal is configured to interact with a user via a corresponding human-machine interface.
11. The communication system according to claim 10 , wherein the connection module prohibits the third-party device from accessing the signals if the usability index is a denial attribute.
12. The communication system according to claim 10 , wherein the connection module allows the third-party device to read the signals if the usability index is a processing attribute.
13. The communication system according to claim 10 , wherein the connection module allows the third-party device to post-process the signals if the usability index is a post-processing attribute.
14. The communication system according to claim 10 , wherein the first terminal further comprises an initiation module, the initiation module being configured to send a transmission initiation message, the message comprising the usability index.
15. A non-transitory computer-readable storage medium storing instructions of a computer program for implementing the method according to claim 1 when the computer program is executed by a processor.
16. The method of claim 1 , further comprising the human-machine interface of the second terminal being configured to present data comprised in the stream.
17. A method for requesting a communication between a first terminal and at least one second terminal to be made secure, the method comprising:
the first terminal selecting a usability index of signals of a communication stream to the at least one second terminal, the usability index of the signals comprising an attribute which expresses a rule which authorizes, limits or prohibits a use of the signals in the stream by a third-party device;
the first terminal sending the usability index of the signals in a message for initiating a transmission of the communication stream to a node of a communication network; and
the first terminal transmitting the signals of the communication stream to the at least one second terminal via the node of the communication network.
