Imperceptible Digital Watermark for Graphical Interface Authenticity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users can easily alter data displayed in graphical user interfaces by taking screenshots and editing them, leading to fraud and identity theft, as existing technologies lack effective mechanisms to verify the authenticity of the data.
Innovation Solution
A digital watermark is generated and embedded into the graphical interface, making it imperceptible to users, and dynamically updated to verify the authenticity of the data, preventing tampering by re-embedding it into the interface upon changes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If no watermark is embedded, then the graphical interface is simple and easy to operate, but the data can be easily altered and forged
Solution Approach 1:
A digital watermark module is introduced as an intermediary component that operates transparently in the background. The watermark is embedded into the graphical interface without requiring user interaction or visible indication, thus maintaining interface simplicity while providing authentication capability. The watermark verifier acts as a mediator between the displayed data and the user, automatically checking authenticity without adding operational complexity.
Solution Approach 2:
The patent replaces physical security measures (such as sealed documents or signed papers) with a digital watermarking system. Instead of relying on mechanical or physical authentication methods, the solution uses digital signal processing to embed and verify watermarks within the graphical interface data, substituting physical security mechanisms with computational verification.
2Reliability
If a static watermark is embedded, then the implementation is simple, but the watermark becomes invalid when data changes
Solution Approach 1:
The watermark system transitions from a static state to a dynamic one. The watermark is generated based on the actual data content and updated automatically when data changes occur. The system continuously monitors for data modifications and regenerates the watermark accordingly, ensuring the watermark remains valid and synchronized with the displayed information throughout the application's runtime.
Solution Approach 2:
The watermark is generated and embedded in advance before the graphical interface is displayed to the user. When data changes are detected, the system proactively updates the watermark before the next display cycle, ensuring authenticity verification is always current. This preliminary action prevents the need for complex real-time verification during user interaction.
3Ease of operation
If screenshot capture is allowed, then the user experience is natural and unrestricted, but the captured image can be edited and used for fraud
Solution Approach 1:
The patent acknowledges that screenshot capability cannot be easily restricted without impacting user experience, so it converts the potential harm into a benefit. The watermark, which is imperceptible to users during normal viewing, becomes the key to detecting tampering. When a screenshot is captured and subsequently edited, the watermark verification fails, alerting users to the alteration. Thus, the same screenshot capability that enables fraud also provides an opportunity for verification when combined with watermarking.

AI summary
Apparatuses, methods, systems, and program products are disclosed for watermark security. An apparatus includes a watermark module configured to generate a digital watermark to be presented as part of a graphical interface based on data presented on the graphical interface. A digital watermark verifies an authenticity of data to be presented in a graphical interface. An apparatus includes a presentation module configured to embed the digital watermark into the graphical interface prior to the data being presented in the graphical interface such that the digital watermark is graphically imperceptible to a user, dynamically update the digital watermark during runtime in response to detecting a change in the at least a portion of the data that is encoded into the digital watermark, and re-embed the digital watermark into the graphical interface in response to the digital watermark being updated.
