Holographic Security Shield for Public Display Confidentiality
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional methods fail to adequately secure displayed content from unauthorized viewing in public settings, particularly when users interact with devices, and lack automatic measures to obscure confidential information based on its nature.
Innovation Solution
A system and method using holographic projectors to generate a masking surface that obscures content from third parties while allowing the user to view it, by determining the need for security based on metadata and activating specific projection elements to create a holographic security shield, and adjusting holographic image parameters to enhance visibility of objects of interest.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional display methods are used in public settings, then device complexity remains low and ease of operation is maintained, but content security is compromised and unauthorized viewing occurs
Solution Approach 1:
The patent transitions from conventional 2D flat displays to 3D holographic displays that project images into the air space above the device. This dimensional change allows the display content to be viewed only from specific angles and positions, inherently preventing unauthorized viewing from other directions while maintaining standard display functionality.
Solution Approach 2:
The holographic display system segments the viewing experience by creating spatially separated viewing zones. The display content is projected as multiple angular views that are only visible from specific positions, effectively segmenting the audience into authorized viewers (at correct positions) and unauthorized viewers (at incorrect positions), thus securing content without adding complex access control mechanisms.
2Reliability
If holographic projectors are activated to secure content, then content security is improved, but energy consumption increases
Solution Approach 1:
The holographic projector operates periodically rather than continuously, activating only when the device detects it is in a public or unauthorized environment. The system uses environmental sensors to detect presence of other devices or public settings, then temporarily activates the holographic display for the duration of the potential security risk, returning to standard display mode when the risk subsides.
Solution Approach 2:
The display system dynamically switches between conventional 2D display mode and holographic 3D display mode based on real-time environmental conditions. The controller continuously monitors sensor data and adjusts the display mode accordingly, using the holographic projector only when and where security is needed, thus minimizing energy consumption while maintaining security effectiveness.
3Reliability
If holographic masking surface is generated to obscure content, then unauthorized viewing is prevented, but visibility for authorized users must be maintained
Solution Approach 1:
The holographic display creates different visual qualities for different spatial locations. For authorized users positioned at the correct viewing angle, the holographic image appears bright and clear. For unauthorized users at other positions, the same holographic projection appears dim or invisible. This local quality differentiation ensures confidentiality for unauthorized viewers while maintaining full visibility for authorized users.
Solution Approach 2:
The holographic projection utilizes specific optical properties and light interference patterns that create visible images only from certain angles. The display dynamically adjusts the optical characteristics of the holographic projection based on detected viewer positions, ensuring that content remains visible to authorized users while appearing obscured or invisible to unauthorized viewers from different angles.

Function Achieved in This Case
Effectively secures content from unauthorized viewing while allowing authorized users to interact with and view their devices, enhancing visibility of important objects while maintaining confidentiality.
Implementation Method 1
A hologram may be an encoding of a light field as an interference pattern of variations in opacity, density, or surface profile of a medium
Implementation Method 2
When suitably lit, the interference pattern diffracts the light into a reproduction of the original light field

AI summary
Systems, methods, and computer-readable media are disclosed for representing a transfer of a digital object using holographic images. User input is received that is indicative of a selection of the digital object for transfer from a sending device to a receiving device. Spatial attribute data is generated based at least in part on at least one of a distance or a relative orientation between the sending device and the receiving device, and a transition path is determined based at least in part on the spatial attribute data. Holographic image data is then generated based at least in part on the transition path, and the holographic image data is sent to one or more holographic projectors to cause a first holographic image representative of the digital object and a second holographic image representative of the transition path to be projected.
