Biometric Authentication via Molecular Snapshots
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional biometric authentication methods lack effectiveness and security, particularly in adapting to changes in user molecular composition over time, necessitating improved techniques for authenticating users.
Innovation Solution
The method involves obtaining a reference molecular snapshot of a user by ingesting nanoparticles, which target specific cell types, and using a scanning device to compare it with a responsive molecular snapshot during authentication, with the option to update the reference snapshot by altering nanoparticle composition over time.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional biometric authentication methods are used, then authentication can be performed, but security and effectiveness are insufficient and cannot adapt to changes in user molecular composition over time
Solution Approach 1:
The patent implements dynamic biometric authentication by periodically updating the reference molecular snapshot with new snapshots obtained at different times. This allows the authentication system to adapt to changes in the user's molecular composition over time, maintaining both security and reliability without requiring complete re-enrollment
Solution Approach 2:
The system changes the temporal parameter of biometric authentication by introducing time-based updates to the reference snapshot. Instead of using a static reference, the system incorporates multiple snapshots taken at different times, allowing the authentication parameters to evolve and adapt to natural molecular composition changes
2Device complexity
If static biometric data is used for authentication, then the authentication process is simple, but it becomes vulnerable to spoofing and cannot detect molecular composition changes
Solution Approach 1:
The system performs preliminary actions by obtaining multiple reference molecular snapshots at different times before the actual authentication challenge. This creates a temporal baseline that must be matched, making spoofing attempts more difficult while maintaining a relatively simple authentication process for the user
Solution Approach 2:
The authentication system incorporates feedback by comparing the responsive molecular snapshot against multiple time-stamped reference snapshots. This feedback mechanism detects whether the molecular composition has changed significantly, providing security against spoofing while keeping the user-facing process simple

AI summary
Techniques are provided for authenticating a user using molecular snapshots of the user. One method comprises obtaining enrollment information of a user, wherein the enrollment information comprises a reference molecular snapshot of the user obtained following an ingestion by the user of nanoparticles; initiating a challenge to the user in connection with an authentication request by the user to access a protected resource; processing a responsive molecular snapshot obtained in response to the challenge, wherein the processing comprises evaluating the responsive molecular snapshot obtained in response to the challenge relative to the reference molecular snapshot; and resolving the authentication request based on the evaluating. The ingested nanoparticles optionally target one or more predefined cell types, and wherein the resolving further comprises the step of evaluating a ratio of cell types in the responsive molecular snapshot.
