Cryptographic Watermarking for Fuel Dispenser Content Security
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Fuel dispensers lack the ability to securely integrate and manage different business applications and services without compromising customer data security, as existing authentication methods are burdensome and prone to security risks.
Innovation Solution
Implementing cryptographic watermarking to authenticate content executed or rendered on the device, where unauthenticated content is terminated or blocked, ensuring only authorized applications or services can execute or present content by embedding watermarking information within the content and verifying it during rendering.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional signature verification is implemented before content execution, then content security is improved, but device complexity and processing burden increase
Solution Approach 1:
The patent applies preliminary action by embedding cryptographic watermarking information in content during the content creation phase, before the content reaches the fuel dispenser. This pre-prepared authentication mechanism eliminates the need for complex real-time signature verification at the device, as the watermarking data is already embedded and can be quickly validated during content rendering.
Solution Approach 2:
The patent extracts the authentication function from the fuel dispenser device itself and relocates it to the content layer through embedded watermarking. Instead of requiring the device to perform complex cryptographic signature verification, the authentication logic is taken out and embedded within the content structure, simplifying the device's verification process to checking embedded watermarking data.
2Adaptability or versatility
If multiple business applications are integrated into fuel dispensers, then functionality and revenue potential are improved, but security risk increases
Solution Approach 1:
The patent applies universality by creating a unified content authentication system that works across multiple different business applications and content types on fuel dispensers. The cryptographic watermarking mechanism provides a universal security layer that can authenticate various applications (loyalty programs, payment processing, advertising) without requiring application-specific security implementations, enabling secure multi-functionality.
Solution Approach 2:
The patent introduces cryptographic watermarking as an intermediary security layer between the content and the fuel dispenser execution environment. This intermediary mechanism mediates the trust relationship, allowing untrusted third-party applications to be authenticated and executed securely on the dispenser without compromising the device's security, thus enabling application versatility while maintaining security.
3Reliability
If content authentication is performed at the processor level during rendering, then security control is improved, but processing time increases
Solution Approach 1:
The patent applies preliminary action by pre-embedding cryptographic watermarking information in the content during creation, so that authentication data is already prepared and available during rendering. This eliminates the need for time-consuming real-time cryptographic operations during content execution, as the watermarking can be quickly extracted and validated from the pre-prepared content structure.

AI summary
Systems and methods for watermarking content and authenticating watermarked content are provided. Content is rendered on a display while watermarking information embedded in portions of the content are obtained. The watermarking information is verified to authenticate the content. If the content is not authentic, or is not authenticated within a period of time, the content can be terminated or otherwise blocked from rendering on the display.
