Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing wearable devices struggle to provide secure and personalized augmented reality experiences by ensuring that only the wearer can decrypt and view encrypted content while maintaining data privacy, especially in public or unsecured networks.

Innovation Solution

A method and apparatus for wearable devices that store a wearer decryption code, capture and process visible codes using an image sensor, and decrypt the content using the wearer's unique decryption key to present it as an overlay in the augmented reality view, while utilizing separate network connections for the decryption code and visible code transmission.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If encrypted content is transmitted over network connections to wearable devices, then data privacy and security are improved, but network vulnerability and potential interception risks increase

Engineering Contradiction:

Improvedata securityVSAvoidnetwork interception risk

Core Design Contradiction:

ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The patent extracts the decryption function from the network transmission process by providing decryption keys to wearable devices locally. The encrypted content remains secure on the server while the wearable device receives only the decryption key through secure channels, separating the confidential content from the transmission process and eliminating network interception risks.

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

The patent introduces wearable devices as intermediaries that receive encrypted content and decryption keys separately. The device acts as a secure mediator that combines the encrypted content with the decryption key locally to reveal the original content, preventing direct exposure of unencrypted data over the network.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Adaptability or versatility

If decryption keys are provided to multiple wearable devices, then content accessibility is improved, but security control and personalized access become more difficult

Engineering Contradiction:

Improvecontent accessibilityVSAvoidsecurity control

Core Design Contradiction:

Adaptability or versatilityVSReliability

Solution Approach 1:

The patent applies local quality by providing different decryption keys to different wearable devices based on their specific characteristics, wearer identity, or access permissions. Each device receives a customized decryption key that enables selective access to encrypted content, allowing the system to maintain security control while enabling multiple devices to access content according to their authorized permissions.

Inventive Principle:

Principle #3Local quality

AI summary

A method of decrypting an encrypted message. The method comprises storing a wearer decryption code in a memory of a wearable mobile device having a head-worn augmented display which generates an augmented reality view for a wearer of the wearable mobile device, capturing using the wearable mobile device a video sequence including at least one frame imaging a visible code using an image sensor of the wearable mobile device, processing the video sequence to identify the visible code, decrypting the visible code using the wearer decryption code to create an decrypted content, and presenting the decrypted content on top of at least some of the visible code in the augmented reality view.
