Automated OTP Generator with Sensor-Embedded Authentication Codes
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing one-time password (OTP) generators require manual replacement or disablement when batteries fail or tampering is suspected, causing delays and stress for users and institutions, and lack the ability to convey additional information for automated operations.
Innovation Solution
An automated OTP generator system that includes sensors and an authentication server to detect conditions such as battery low, tampering, or duress, modifying the OTP to include additional information, allowing the server to initiate replacement or disablement without user input.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual replacement or disablement of OTP generators is implemented, then user control and simplicity are maintained, but delays and stress occur when batteries fail or tampering is suspected
Solution Approach 1:
The OTP generator automatically detects battery status and tampering conditions through integrated sensors, and communicates this information to the authentication server via the OTP code itself. The system enables self-service by allowing the OTP generator to autonomously monitor its own health status and trigger replacement workflows without requiring user intervention or manual reporting.
Solution Approach 2:
The system implements feedback by embedding sensor data (battery status, tampering detection) directly into the OTP code structure. The authentication server analyzes these embedded signals and provides automated responses, creating a closed-loop feedback system that continuously monitors OTP generator health and initiates replacement procedures based on real-time conditions.
2Reliability
If OTP generators include sensors and automated communication capabilities, then proactive replacement is enabled, but device complexity increases
Solution Approach 1:
The OTP generator uses its existing display and communication infrastructure to convey sensor data and status information to the authentication server. Rather than adding dedicated communication hardware, the system repurposes the existing OTP display mechanism to carry additional diagnostic information, achieving multi-functionality with minimal additional components.
Solution Approach 2:
The system changes the parameters of the OTP code itself, embedding additional data fields that represent sensor readings (battery status, tampering flags) within the standard OTP structure. This allows the OTP to carry multiple pieces of information simultaneously without requiring separate communication channels or protocols.
3Extent of automation
If additional information is embedded in the OTP code, then automated operations are enabled, but OTP code structure becomes more complex
Solution Approach 1:
The system embeds additional information (sensor data, status flags) within the existing OTP code structure, creating a nested information hierarchy. The OTP code contains the primary authentication data, while additional sensor-derived information is nested within the same code structure, allowing the authentication server to extract multiple layers of information from a single compact code.

AI summary
Apparatus and methods for automating replacement and disablement of one-time password (“OTP”) generators are provided. The apparatus and methods may include an authentication engine on a server and an OTP generator that may generate a standard OTP or an enhanced OTP that includes additional information beyond the standard OTP. The authentication engine may analyze the additional information when an enhanced OTP is received, and in response to that additional information, execute an operation. The operation may include initiating the sending of a new OTP generator to a user when the OTP generator's battery is failing or the OTP generator has been damaged or disabling an OTP generator when the OTP generator has been tampered with.
