Security Module Viewer Authentication Method
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for rewarding viewer attention during TV commercials are vulnerable to cheating, as they do not ensure unique and unpredictable interaction from each viewer, allowing potential hackers to simulate presence and bypass authentication.
Innovation Solution
A method that uses a security module in the receiver/decoder to generate personalized messages and require viewer interaction, ensuring that each viewer responds uniquely to a message embedded in the commercial content, preventing remote activation and ensuring genuine presence.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a reward system is implemented to encourage viewer attention during commercials, then viewer engagement is improved, but the system becomes vulnerable to cheating and remote activation
Solution Approach 1:
The system performs preliminary actions by generating a unique challenge message before the viewer interaction occurs. The security module creates a personalized challenge that must be responded to in real-time, preventing remote activation because the challenge is generated based on the specific viewer's presence and timing. This preliminary generation of authenticated challenges ensures that only actual viewers can participate in the reward system.
2Ease of operation
If simple interaction methods are used to test viewer presence, then ease of operation is improved, but measurement precision of actual viewer presence deteriorates
Solution Approach 1:
The security module acts as an intermediary between the viewer and the reward system. It generates unique challenge messages that are embedded in the commercial content and verifies the viewer's response. This intermediary layer maintains ease of operation for the viewer while ensuring precise measurement of actual presence through cryptographic verification of the response against the challenge.

AI summary
The present invention relates to a method for authenticating the presence of a viewer during a presentation of video content (CT), said method using a system comprising at least a receiver/decoder (RX), a display unit (MON) and a viewer input means (RC), said receiver/decoder (RX) comprising a security module (SM), said method comprising the following steps: - receiving a first signal (S1 ) comprising at least the video content (CT); - displaying the video content (CT) on the display unit (MON); - receiving a second signal (S2) comprising a trigger (TR); - transferring the trigger (TR) to the security module (SM), thus causing said security module (SM) to generate a personalised value (U); - displaying a message (MES) on the display unit (MON), said message (MES) comprising at least part of said personalised value (U) and being designed to provoke the viewer to respond; - generating, in the security module (SM), an expected response (EXP) based on at least part of said personalised value (U); - receiving the viewer's response (REP); - transferring the viewer's response (REP) to the security module (SM); - comparing the viewer's (REP) response with the expected response (EXP) thus producing a result (RES) for said authentication.
