Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing authentication methods, particularly biometric ones, are vulnerable to variations due to age and health status, and traditional password-based systems are susceptible to brute-force attacks, posing risks to secure data access.
Innovation Solution
Utilizing circular dichroism spectroscopy to generate unique spectroscopic signatures from biological or organic molecules, which are then used as authentication keys in a multi-factor authentication system, combining with traditional methods to enhance security.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If biometric authentication methods are used, then ease of operation is improved, but reliability deteriorates due to variations with age and health status
Solution Approach 1:
The patent changes the authentication parameter from biometric physical characteristics (which vary with age and health) to spectroscopic signatures of molecules (which are stable and reproducible). By measuring the spectroscopic properties of molecules associated with or specific to an individual, the system achieves both ease of operation and high reliability, as molecular spectra do not change with physiological conditions.
2Device complexity
If traditional password-based authentication is used, then device complexity is reduced, but security deteriorates due to susceptibility to brute-force attacks
Solution Approach 1:
The patent replaces the mechanical/password-based authentication system with a spectroscopic measurement system. Instead of relying on user-remembered secrets vulnerable to brute-force attacks, the system uses optical measurement of molecular spectra, which provides high security through the uniqueness and difficulty of reproducing spectral signatures, while maintaining relatively simple system architecture.
3Measurement precision
If spectroscopic methods with high resolution are used, then measurement precision is improved, but device complexity increases
Solution Approach 1:
The patent employs a spectroscopic device that serves multiple functions: it measures the spectroscopic signature for authentication, and can also identify and quantify multiple different molecules simultaneously. This multi-functionality justifies the device complexity by providing enhanced measurement precision and additional information about the sample, making the increased complexity worthwhile.

Implementation Method 1
A circular dichroism (CD) spectrum in the far UV is the response of a chiral molecule to wavelengths between 180 and 260 nm. The amino acids and nucleotides that make up proteins and nucleic acids have the ability to favor the faster absorption of the right or left component of the polarization of a light wave.
