Secure Data Translation via Low-Energy Wireless Link
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for transferring sensitive data between devices lack effective access control, as machine-readable identifiers can be intercepted or accessed by unauthorized devices unless encrypted, and network transmission poses risks of data interception and unauthorized access.
Innovation Solution
A system that uses cryptographic keys to encrypt and segment data within machine-readable identifiers, allowing only authorized devices with the corresponding keys to access specific portions of the data, enabling secure transmission without a network and controlling access levels for different medical or personal information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If data is transmitted over a wireless communication link, then data transfer between devices is enabled, but unauthorized devices can intercept and access the data
Solution Approach 1:
The data is divided into multiple segments or portions, with different access levels assigned to each segment. Authorized devices can access only the specific segments they are permitted to view, while unauthorized devices cannot access any segments without proper authentication credentials.
Solution Approach 2:
Different portions of the data are encrypted with different encryption keys or access levels. Each segment has its own security properties, allowing fine-grained control over what specific devices can access based on their authorization level.
2Reliability
If encryption is applied to protect data, then unauthorized access is prevented, but access control management becomes more complex
Solution Approach 1:
The system dynamically assigns and manages access levels for different devices. Access credentials can be provisioned, modified, or revoked as needed, allowing flexible access control management that adapts to changing security requirements without requiring complete system reconfiguration.
Solution Approach 2:
An intermediary system or service manages the distribution and validation of access credentials between devices and the protected data. This intermediary handles the complexity of key management and access control policies, simplifying the burden on individual devices while maintaining strong security.
3Ease of operation
If all data is encrypted with the same key, then implementation is simple, but selective access control for different devices is lost
Solution Approach 1:
Data is segmented into multiple portions, each encrypted with a different key or access level. This allows simple implementation of encryption while simultaneously enabling selective access control, as each device can be granted access to specific segments based on its authorization.
Solution Approach 2:
Different encryption keys or access levels are applied to different portions of the data locally. This maintains implementation simplicity through automated key management while providing the versatility of selective access control for different devices based on their specific authorization levels.

AI summary
Disclosed are various embodiments for providing access control to the sensitive data, such as personal medical history. A first client device executes an application that ingests input data entered by a user via a user interface of the first client device, encrypts at least a first portion of the input data using a first cryptographic key, and transmits the encrypted input data over a low-power wireless private area network (WPAN), such as a Bluetooth Low-Energy (BLE) WPAN, for example. A second client device executing a second application receives the encrypted input data transmitted over the low-power WPAN by the first client device and use the first cryptographic key to decrypt the encrypted input data.
