Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current secure access methods, such as passwords, credit cards, and fingerprint recognition, are inconvenient and prone to misuse, requiring users to remember multiple passwords or carry cards, and are susceptible to forgery.
Innovation Solution
A biometric device that utilizes a sensor reacting to chemical elements in sweat to create a unique sweat gland map, combining this with standard fingerprint detection for enhanced authentication, featuring a hydrochromic polymer layer and image processing to generate and verify authentication results.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional authentication methods (passwords, fingerprint readers) are used, then access control is achieved, but user convenience deteriorates and security is compromised
Solution Approach 1:
The patent employs a hydrochromic layer that changes color in response to sweat gland moisture, creating a visual map of sweat pore locations. This color change mechanism enables unique biometric identification while maintaining ease of use, as users simply need to place their finger on the sensor without complex operations.
Solution Approach 2:
The patent replaces mechanical fingerprint reading systems with a chemical-biological detection system that visualizes sweat gland patterns through color changes. This substitution eliminates the need for mechanical contact and pressure, improving both security through unique sweat pore mapping and convenience through simple finger placement.
2Reliability
If multiple passwords are used for different accounts, then security is improved, but user burden increases
Solution Approach 1:
The sweat pore map authentication system serves as a universal biometric identifier that can be applied across multiple accounts and systems. The unique sweat gland pattern acts as a single authentication credential that replaces multiple passwords, enabling fast access to various accounts without requiring users to remember different credentials.
3Ease of operation
If fingerprint readers are used, then authentication is achieved, but susceptibility to forgery increases
Solution Approach 1:
The hydrochromic layer's color change response to sweat provides a dynamic, multi-dimensional authentication mechanism that is difficult to forge. Unlike static fingerprint images, the sweat pore map requires actual physiological interaction, creating authentication data that is inherently harder to replicate or spoof.
Solution Approach 2:
The hydrochromic layer acts as an intermediary between the user's sweat glands and the detection system. This intermediary transforms invisible sweat secretion into visible color patterns, creating an authentication mechanism that captures unique physiological characteristics while protecting against direct forgery attempts.

AI summary
A biometric device that may include a sensor that reacts to a chemical element associated with a sweat gland; wherein when the sensor is contacted by an area of a skin of a person, an image that comprises information about locations of sweat glands within the area of the skin of the person is generated by the sensor; an image processor that is configured to generate an authentication result by comparing between (a) the information of the image generated by the sensor and (b) reference information of locations of sweat glands of a given person; wherein the authentication result indicates whether the person is the given person; and a communication module for communicating an authentication result indication.
