Implantable Device Telemetry Authentication via Motion Correlation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for secure and authorized telemetry solutions for implantable medical devices (IMDs) to prevent unauthorized access and ensure patient privacy, as existing commercially available telemetry protocols lack effective security measures.
Innovation Solution
A method and system that compares electronic information from external devices with IMDs using processors to determine a correlation, initiating a telemetry session only when a defined level of similarity or correlation is met, utilizing various forms of data such as images, motions, speech signals, and secure information to authenticate and authorize communication.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If commercially available telemetry protocols are used to facilitate widespread provisioning of telemetry solutions, then ease of operation and adaptability are improved, but security and reliability deteriorate due to lack of effective security measures
Solution Approach 1:
The system performs preliminary authentication actions before establishing telemetry communication. External devices must present credentials or undergo verification processes prior to being granted access to the implantable medical device, ensuring security is established before operation begins
Solution Approach 2:
The system introduces an intermediary authentication layer between the external device and the implantable medical device. This intermediary verifies credentials and establishes secure communication channels, preventing direct unauthorized access while maintaining ease of operation for authorized users
2Reliability
If telemetry communication is restricted and policed to prevent unauthorized access, then security and reliability are improved, but device complexity and difficulty of operation increase
Solution Approach 1:
The system implements self-service authentication mechanisms where the implantable medical device and external devices autonomously verify credentials and establish secure connections without requiring complex manual authorization procedures. The device itself participates in the authentication process, reducing the burden on users
Solution Approach 2:
The system employs universal authentication protocols that can be applied across different device types and communication scenarios. By using standardized credential verification methods, the system maintains security without requiring device-specific complex authorization systems

AI summary
Techniques for facilitating authorized telemetry with an implantable device are provided. In one embodiment, for example, a method includes comparing, by a first device having a processor, first electronic information with second electronic information. The first electronic information is indicative of a first motion of a second device external to a body in which the implantable device is located, and the second electronic information is indicative of a second motion of the implantable device. The method also includes determining whether a defined level of correlation exists between the first electronic information and the second electronic information, and initiating a telemetry session between the second device and the implantable device based on a determination that the defined level of correlation exists between the first electronic information and the second electronic information.
