Palm Vein Recognition System for Frictionless User Authentication
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional user identification and authentication methods in computing devices are often cumbersome and require users to carry or use traditional forms of identification, such as ID cards or personal devices.
Innovation Solution
A user-recognition system that utilizes biometric-recognition techniques, specifically by enrolling users through image data of their palms, which is then used for identification and authentication within a facility, allowing for streamlined checkout processes and access control.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional user identification methods (username/password, biometric data) are used, then user authentication is achieved, but the process becomes cumbersome and requires users to carry traditional forms of identification
Solution Approach 1:
The patent extracts the identification function from traditional carriers (ID cards, phones) and embeds it directly into the environment through palm vein recognition. The system removes the need for users to carry physical or digital identification by using their body's natural biometric characteristics as the key.
Solution Approach 2:
The system uses the user's own palm veins as the authentication mechanism, eliminating the need for external identification carriers. The user's body itself serves as the authentication medium, making the system self-sufficient and removing dependency on external devices or cards.
2Productivity
If palm vein recognition is implemented, then user identification efficiency is improved and traditional ID methods are eliminated, but the system requires image data capture and processing capabilities
Solution Approach 1:
The patent replaces mechanical identification systems (physical ID cards, manual verification) with an optical-biometric system that captures palm vein images and processes them electronically. This substitution eliminates physical carrier requirements while enabling automated, efficient recognition.
Solution Approach 2:
The system introduces an intermediary processing layer between the user's palm and the identification system. Image capture devices capture palm vein patterns, which are then processed through recognition algorithms to identify users, creating a bridge between physical presence and digital identification.
3Reliability
If biometric data collection is used, then authentication security is enhanced, but user privacy concerns and data protection requirements increase
Solution Approach 1:
The system focuses on a specific localized feature (palm veins) rather than collecting comprehensive biometric data. By targeting only the unique vascular patterns in the palm, the system achieves secure authentication while minimizing the scope of data collection and potential privacy risks.
Solution Approach 2:
The patent transforms the authentication approach by changing from traditional username/password or surface-level biometric verification to deep-tissue vascular pattern recognition. This parameter change in the type of biometric data used provides enhanced security while the non-invasive nature of the measurement reduces privacy concerns compared to more invasive biometric collection methods.
Data Source
AI summary
This disclosure describes techniques for identifying users that are enrolled for use of a user-recognition system and updating identification data of these users over time. The user-recognition system may include a user-recognition device having projector(s) and/or camera(s) aimed substantially downwards. The device may include a projector that projects a visible light ring downwards, which the user may use to place their upward-facing palm in the appropriate location. For instance, the user may place their palm face-up with the light ring substantially centered thereon, after which a camera of the user-recognition device may generate image data of the palm, which in turn may be used to identify the user.
