Vascular Dynamics Biometric Authentication via Mobile Inversion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Vein pattern authentication, while contactless and resistant to forgery, faces challenges such as the need to present the backside of the hand for scanning, which can be inconvenient or burdensome in certain situations, and is susceptible to spoofing methods like using fake hands.
Innovation Solution
Authentication based on vascular dynamics, which involves monitoring changes in blood vessel properties like position, size, volume, pressure, velocity, and acceleration over time, allowing for non-contact, minimally disruptive authentication using electronic devices located proximate to the body, such as in a pocket.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If vein pattern authentication is used, then security against forgery is improved, but ease of operation deteriorates due to the need to present the backside of the hand
Solution Approach 1:
The patent inverts the conventional vein scanning approach by moving the scanner from a fixed position requiring hand presentation to a mobile device carried by the user. Instead of the user bringing their hand to the scanner, the scanner (mobile device) is brought to the user's body, eliminating the need to present the backside of the hand while maintaining vein pattern-based security
2Reliability
If vein pattern authentication is used, then resistance to spoofing is improved, but adaptability deteriorates due to difficulty in certain situations
Solution Approach 1:
The patent applies dynamics by transitioning from a static fixed scanner to a dynamic mobile device that can be positioned anywhere on or near the user's body. This dynamic approach allows authentication to occur in various situations including when the user is not proximate to a fixed system or when wearing gloves, while the vein pattern recognition maintains resistance to spoofing
Solution Approach 2:
The patent uses the mobile device as an intermediary between the user and the authentication system. The mobile device carries the scanning capability and can be positioned adaptively in different situations, acting as a mediator that enables authentication without requiring direct contact or specific hand presentations
3Ease of operation
If contactless vein scanning is used, then convenience is improved, but device complexity increases due to the scanning system requirements
Solution Approach 1:
The patent leverages the mobile device's existing multi-functionality to perform vein pattern scanning. The mobile device, already equipped with cameras and processors for various functions, is adapted to perform contactless vein scanning, avoiding the need for dedicated complex scanning hardware while maintaining convenience

AI summary
Introduced here are approaches to authenticating unknown persons based on variations in the properties of blood vessels over time. At a high level, these approaches rely on monitoring changes in a property of a blood vessel that occur over time. Examples of properties include the position, size, volume, and pressure of the blood vessel, as well as the velocity and acceleration of blood flowing through the blood vessel.
