Health Certificate Decryption Protocol for Wearable Devices
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current digital badges lack the ability to communicate non-verbally between users in line of sight, failing to transmit health status, emotions, and other relevant information, and do not facilitate social distancing or contact tracing effectively, which is crucial for public health and economic recovery during pandemics.
Innovation Solution
A non-verbal line of sight electronic communication protocol (NVP) using standardized symbols and colors on user-worn devices to enable instant communication of health status, emotions, and intentions, allowing for secure, real-time health certification and social distancing alerts.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If digital badges display static identity information only, then device complexity is reduced, but information transmission capability and interactivity are limited
Solution Approach 1:
The patent introduces a standardized communication protocol as an intermediary framework that enables badges to exchange health status information without requiring complex custom communication logic in each device. The protocol acts as a mediator that standardizes data formats, encryption methods, and transmission rules, allowing information flow between badges while keeping individual device complexity manageable.
Solution Approach 2:
The badge system is designed with multi-functional capabilities including health status display, encryption/decryption operations, contactless communication, and social distancing enforcement. This universal design allows a single device to perform multiple functions that would otherwise require separate systems, reducing overall system complexity while improving information transmission capability.
2Loss of information
If health certification information is displayed in detail, then information completeness is improved, but privacy security and data protection are compromised
Solution Approach 1:
The patent applies different levels of information disclosure to different contexts and users. Health certification data is encrypted by default and only decrypted/displayed when appropriate authentication occurs. The system provides localized quality control where sensitive information remains protected unless specific conditions are met, balancing information completeness with privacy protection through context-aware disclosure.
Solution Approach 2:
Encryption and decryption protocols serve as intermediaries between the health certification data and the display function. The data remains in protected form during transmission and storage, and only the authenticated recipient can decrypt and view the information. This intermediary layer ensures that information completeness is achieved only when privacy security requirements are satisfied.
3Reliability
If real-time health status monitoring is implemented, then public health safety is improved, but device power consumption increases
Solution Approach 1:
The system implements periodic health status updates rather than continuous real-time monitoring. Badges transmit health information at scheduled intervals or when status changes occur, rather than maintaining constant communication. This periodic action maintains public health safety by ensuring timely information exchange while significantly reducing power consumption compared to continuous monitoring.
4Adaptability or versatility
If contactless communication protocol is added to badges, then interactivity and information sharing are improved, but device complexity and programming requirements increase
Solution Approach 1:
The patent standardizes communication parameters including data formats, encryption keys, transmission protocols, and authentication methods. By defining fixed parameters and standardized interfaces, the system enables versatile badge-to-badge communication without requiring complex custom programming in each device. The standardized parameters reduce implementation complexity while maintaining adaptability across different badge instances.

AI summary
Systems and Methods are disclosed for real-time decryption of a health registry-issued certificate for signaling a user vaccination and/or test status on a user device comprising the steps of: coupling a first user mobile device to a health registry for real-time decryption of a health registry-issued health certificate over a network; outputting on the first user mobile device at least one of an audible output, visual output, vibrational output, and/or textual output based on a pre-defined signaling protocol to signal a user vaccination status based on a token derived from the real-time decrypted health certificate; and decoding a device identifier/tag or token from the first user mobile device by a second user mobile device, fixed access device, or hand-held scanner, signaling to a second user a first user vaccination status based on a pre-defined signaling protocol and the tag/token.
