Portable Device Location Verification for Broadcast Access Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing geolocation systems for controlling access to audiovisual content are ineffective inside buildings due to the inability to receive satellite signals, allowing unauthorized access when a portable device in the authorized area transmits a false location to verify access.
Innovation Solution
A method using a portable device with integrated localization means, such as GPS or mobile network identifiers, to verify the location of a receiver, which generates and transmits a unique code to ensure that the device is physically present in the authorized area before allowing content access, using secure communication protocols like NFC or Bluetooth to prevent tampering.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a portable device transmits location data to verify receiver access, then access control can be implemented, but the system becomes vulnerable to unauthorized access when the device is physically distant from the receiver
Solution Approach 1:
The patent introduces an intermediary verification process where the portable device must be physically present at the receiver to complete authentication. The device acts as a mediator that can only verify location when co-located with the receiver, preventing remote spoofing attacks while maintaining access control functionality.
Solution Approach 2:
The system implements feedback by requiring the portable device to actively verify its own location relative to the receiver at the moment of access request. This real-time feedback mechanism ensures that location data cannot be pre-faked or transmitted from a distant location, as the verification only succeeds when the device is physically present in the authorized area.
2Measurement precision
If geolocation satellites are used for location verification, then location can be determined, but the system fails inside buildings where satellite signals cannot be received
Solution Approach 1:
The patent makes the location verification system universal by implementing multiple location determination methods that work in different environments. The system can switch between satellite-based geolocation for outdoor use and alternative methods (such as Wi-Fi positioning, cellular tower triangulation, or indoor beacon systems) for indoor environments, ensuring functionality across all settings.
Solution Approach 2:
The system adapts to different environments by changing the operational parameters of location verification. When satellite signals are unavailable indoors, the system transitions to using other available signals and measurement parameters, such as radio frequency-based positioning or proximity detection through communication protocols, maintaining verification capability across varying environmental conditions.

AI summary
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.
