Public Display Personalization with Encrypted Private Viewing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The proliferation of display devices in public and private settings poses challenges in communicating targeted information while maintaining privacy, as existing technologies struggle to differentiate between authorized and unauthorized viewers.
Innovation Solution
A system comprising a personalization public display device and user viewing devices that establish display protocols to enable private viewing of personalized images, using encryption, obscuration, or projection techniques to ensure only authorized users can view targeted content.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If display devices are used in public areas to communicate targeted information, then information delivery capability is improved, but privacy protection deteriorates
Solution Approach 1:
The display content is segmented into multiple layers: a public layer visible to all viewers and a private layer visible only to authorized users through their personal viewing devices. This segmentation allows targeted information delivery to specific individuals while maintaining public accessibility for general content.
Solution Approach 2:
A personal viewing device acts as an intermediary between the public display and the user, enabling private viewing of personalized content. The intermediary device receives signals from the public display and presents personalized information to the user, thereby protecting privacy while enabling targeted information delivery.
2Adaptability or versatility
If public displays show personalized content, then targeted advertising capability is improved, but unauthorized access risk increases
Solution Approach 1:
The personal viewing device serves as a secure intermediary that authenticates users before delivering personalized content. It establishes a private communication channel with the public display, ensuring that only authorized users can access personalized advertising content while preventing unauthorized access.
Solution Approach 2:
Different viewing experiences are provided based on user authorization status. Authorized users see personalized targeted advertising content through their personal devices, while unauthorized users only see generic public content. This local quality differentiation enables targeted advertising while maintaining security.
3Loss of information
If encryption and obscuration techniques are implemented, then privacy protection is improved, but device complexity increases
Solution Approach 1:
The personal viewing device acts as an intermediary that handles encryption and obscuration techniques, shielding users from complexity. The device automatically manages secure communication protocols, content authentication, and private display mechanisms, providing privacy protection without requiring users to understand or configure complex security settings.

AI summary
Technologies for displaying public and private images includes a display device and one or more user viewing devices. The display device is configured to display or generate a personalized image or video that is viewable by an authorized user viewing device and not viewable by unauthorized viewing devices. To facilitate the display of the personalized images, the display device and the user viewing device(s) may negotiate a display protocol to be used by the display device to display the personalized image in a private manner. In some embodiment, the display device may also display a public image or video that is viewable by unauthorized viewing devices and/or individuals without viewing devices.
