On-Screen Data Encryption with External Decryption
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing data security solutions fail to protect sensitive information displayed on endpoint devices, such as laptops and tablets, from unauthorized access, particularly in public or crowded spaces where the risk of data theft is higher.
Innovation Solution
The method involves encrypting on-screen data on endpoint devices and authenticating external decryption devices within a defined periphery, allowing only authorized users to access and decrypt the data using augmented or virtual reality devices connected via secure communication protocols, ensuring that only the data owner can view the decrypted information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If data is displayed on endpoint device screens for accessibility and mobility, then ease of operation is improved, but security against unauthorized viewing deteriorates
Solution Approach 1:
The patent applies local quality by rendering different visual representations of the same data at different locations. The encrypted data is displayed on the endpoint device screen in an indecipherable form, while the decrypted readable form is displayed only on the authenticated external device's display, creating location-specific data quality
Solution Approach 2:
The patent introduces an intermediary authentication system that mediates between the endpoint device and external devices. The authentication module verifies external devices and controls decryption, acting as a mediator that allows authorized viewing while preventing unauthorized access
2Reliability
If encryption is applied to on-screen data, then security is improved, but data usability deteriorates
Solution Approach 1:
The patent segments the data viewing function across multiple devices. The endpoint device handles data storage and encrypted display, while authenticated external devices handle decrypted readable display. This segmentation allows both security and usability to be optimized in different locations
Solution Approach 2:
The patent adds a spatial dimension to data access by allowing decrypted viewing on external devices beyond the endpoint device screen. This creates a new dimension for data usability where authenticated users can view readable data on their own displays while the endpoint device continues to show encrypted data
