Capacitive Through-Body Communication for Identity Verification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current identity verification systems in large-scale applications, such as financial institutions and public transportation, face inefficiencies due to the need for manual entry of identification data, which can be time-consuming and require access to off-site servers, especially in high-throughput scenarios.
Innovation Solution
Implementing a capacitive through-body communication system that uses the human body as a signal transmission waveguide to quickly and securely authenticate user identities by transmitting and receiving data between a kiosk-type device and on-body devices, reducing the need for direct physical contact and improving battery life.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If manual entry of identification data is used, then user privacy is protected, but verification time increases and server load increases
Solution Approach 1:
The patent replaces manual mechanical input (typing, swiping) with capacitive sensing that detects body electrical properties. The system uses capacitive coupling between the user's body and the kiosk surface to automatically capture biometric data without manual entry, reducing verification time while maintaining privacy through non-contact sensing
Solution Approach 2:
The patent introduces capacitive coupling as an intermediary mechanism between the user and the kiosk. This intermediary enables automatic data capture through electrical field interaction with the human body, allowing the system to obtain identification data without direct contact or manual input, thus reducing verification time and server load
2Ease of operation
If direct physical contact is required for communication, then data transmission is reliable, but user convenience decreases and interaction time increases
Solution Approach 1:
The patent replaces direct mechanical contact with capacitive coupling, which detects electrical properties through non-contact means. Users simply need to be in proximity to the kiosk surface for automatic data capture, eliminating the need for direct physical contact while maintaining reliable communication through electrical field interaction
Solution Approach 2:
Instead of requiring the user to actively touch or input data, the system inverts the approach by passively capturing data through capacitive sensing when the user is merely in proximity. This inversion of the interaction model significantly improves convenience and reduces interaction time
3Productivity
If on-body devices continuously transmit data, then identity verification is rapid, but battery life decreases
Solution Approach 1:
The patent implements periodic capacitive sensing rather than continuous transmission. The kiosk surface actively senses capacitive changes when a user approaches, triggering data capture only when needed. This periodic action maintains rapid verification capability while dramatically reducing energy consumption compared to continuous transmission
Solution Approach 2:
The system uses the user's own body as the sensing mechanism, leveraging the natural capacitive properties of the human body to trigger communication. This self-service approach eliminates the need for active device transmission, as the body's electrical characteristics automatically initiate the verification process when in proximity, conserving battery life while maintaining speed

AI summary
Methods, systems, and apparatus, including computer programs encoded on a computer storage medium, for capacitive through-body communication. In one aspect, a method includes receiving a selection from a user representing a first individual to prevent identification data to be transmitted by an on-body device, transmitting an identification request to the on-body device associated with the first individual, receiving an indication that a second individual possesses the on-body device associated with the first individual, sending a command to the on-body device associated with the first individual to prevent transmitting the identification data stored on the on-body device associated with the first individual.
