Abstract

The present invention relates to the domain of control of access to audiovisual content transmitted to a receiver, in particular control based on the localization of the receiver.

This invention proposes a method of control of access to content transmitted to a receiver, said receiver being part of an access geographic control system comprising verification means and security means, the method comprising the following steps:

• • acquisition of a current localization by a portable device,
  • transfer of the current localization to the verification means,
  • extraction, in a memory of the verification means, of a localization data set defining at least one area,
  • verification, by the verification means, that the current localization is included in said area, and if so, transmission of an authorization message for the reception of the audiovisual content to the security means relative to the receiver.

Claims

1. A method for controlling access to content transmitted to a receiver, said receiver being part of an access geographic control system comprising verification means and security means, the method comprising:

receiving a verification invitation message by the receiver;

obtaining or generating a unique code by the receiver;

transmitting, to said verification means, said unique code or information that allows verification of the unique code;

transmitting said unique code to a portable device;

receiving, by the verification means, a current localization and the unique code from the portable device;

verifying the unique code received by the verification means, and if the code is correct;

extracting, from a memory of the verification means, a localization data set defining at least one area; and

verifying by the verification means that the current localization is included in said area, and transmitting an authorization message for the reception of the audiovisual content to the security means of said receiver in response to the current localization being included in the area.

2. The method according to claim 1, wherein the receiver on reception of the verification invitation message, generates the unique code and transmits the unique code to the portable device and to the verification means.

3. The method according to claim 1, wherein the receiver extracts the unique code from the invitation message and transmits the unique code to the portable device and to the verification means.

4. The method according to claim 1, wherein the receiver displays the unique code on a screen connected to said receiver and the portable device comprises means for acquiring the unique code.

5. The method according to claim 4, wherein the receiver displays an alphanumeric image on the screen representing the unique code, the portable device comprises a keyboard for entering the unique code.

6. The method according to claim 4, wherein the receiver displays an image representing the unique code, and further comprising:

acquisition of acquiring the image by an optical reading device of said portable device; and

converting the image to obtain the unique code in order to add it to the current localization.

7. The method according to claim 3, wherein the receiver includes local communication means with the portable device, the unique code being sent via the local communication means.

8. The method according to claim 1, wherein the receiver has a remote control, and wherein the portable device is the remote control of said receiver.

9. The method according to claim 1, wherein the verification means are integrated into said receiver, and the receiver comprises local means for communication with the portable device for receiving the current localization and the unique code.

10. The method according to claim 1, in which the portable device is a smart accessory comprising a Global Positioning System (GPS) module and having local means for communication with said receiver, said communication means using an encryption key to secure the message exchanges, further comprising, carried out by the smart accessory:

downloading and loading an application in a memory of said smart accessory;

accessing a management center and identifying the receiver at said management center;

retrieving, from the management center, an encryption key corresponding to said receiver; and

using said encryption key to encrypt and/or sign the current localization data.

11. The method according to claim 1, wherein the verification means are located in a management center and wherein the portable device includes means for communication with said management center independent of the receiver.

12. The method according to claim 1, wherein the verification means are located in the receiver, and that the portable device includes means for communication with said management center independent of the receiver, said center transmitting a message to said receiver containing at least the received localization and the unique code.

13. A system for reception of transmitted audiovisual content, comprising:

a receiver comprising verification means and security means and a screen output; and

a portable device configured to acquire a current localization and transfer said current localization to the receiver;

the receiver being configured to transmit a unique code to said portable device, the portable device being configured to receive said unique code and to compose and transmit to the receiver a message comprising a current localization and said unique code, said verification means being configured to verify the unique code and to determine if the current localization is included in an authorization area and, in response to the current localization being in the authorization area, to transmit an authorization message for the reception of the audiovisual content to the security means.

14. The system according to claim 13, wherein the receiver includes means for generating the unique code, to transmit the unique code to the screen output and to the verification means.

15. The system according to claim 13 wherein the portable device includes an optical reading device configured to acquire an image being displayed on the screen connect to the screen output and converting it in order to obtain the unique code.

16. The system according to claim 13, wherein the portable device is a remote control configured for controlling the receiver, or a smart phone.

17. A receiver for reception of transmitted audiovisual content, comprising:

an interface for receiving the audiovisual content;

a verification means; and

a security means;

the receiver being configured to transmit a unique code to a portable device, and receive from the portable device a message comprising a current localization and said unique code, said verification means being configured to verify the unique code and to determine if the current localization is included in an authorization area and, in response to the current localization being in the authorization area, to transmit an authorization message for the reception of the audiovisual content to the security means.
