Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for individual identification, such as facial recognition, signature authentication, and RFID, have limitations including the need for prior knowledge, vulnerability to forgery, forgetfulness, and practicality issues, which necessitate a more reliable and convenient solution.
Innovation Solution
A bio-implantable identification device with a processor, memory, and transmitter that signs identification requests using a private key, allowing secure communication and software updates, with a master-slave device configuration for redundancy and functionality monitoring.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If RFID devices are used for identification, then identification convenience is improved, but device portability and reliability deteriorate due to loss and theft
Solution Approach 1:
The identification device is implanted within the human body, nesting the electronic device inside a biological container (the body). This eliminates the need to carry external RFID devices while maintaining identification functionality, thereby solving the contradiction between convenience and reliability.
Solution Approach 2:
The patent creates a digital copy of the identification system by implanting an electronic identifier that replicates the function of traditional physical identification devices. This digital/ electronic copy replaces physical carriers (RFID cards, key fobs) that are prone to loss, thereby improving reliability while maintaining ease of operation.
2Ease of operation
If facial recognition is used for identification, then no physical device is needed, but prior knowledge of the person is required and security can be compromised
Solution Approach 1:
The patent extracts the identification capability from external systems (facial recognition databases, physical devices) and embeds it directly within the individual's body. This self-contained approach eliminates dependency on external databases and prior knowledge, thereby improving both accessibility and security reliability.
Solution Approach 2:
The implanted device serves as a self-contained identification system that does not require external verification databases or prior registration of biometric data. The identification capability is intrinsic to the device itself, making the system self-sufficient and more secure against external attacks.
3Ease of manufacture
If traditional identification methods are used, then implementation is simple, but vulnerability to forgery and forgetting occurs
Solution Approach 1:
The patent employs asymmetric cryptography (public-private key pairs) where the private key remains securely stored in the implanted device while the public key is used for verification. This asymmetric structure prevents forgery as the private key never leaves the device, yet maintains implementation simplicity through standardized cryptographic protocols.
