Blood Vessel Image Authentication via Projection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional authentication methods, such as two-step authentication, often rely on physical devices that can be misplaced, damaged, or unavailable, and require additional expenses, while also being vulnerable to cellular service unavailability and password-related issues.
Innovation Solution
A system that authenticates users by projecting an authentication image onto a body part containing a blood vessel, capturing and reading blood vessel data, and comparing it to predetermined points to verify identity, eliminating the need for physical devices and passwords.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If two-step authentication with physical devices is used, then authentication security is improved, but device availability and ease of operation deteriorate due to potential loss, damage, or unavailability of the physical device
Solution Approach 1:
The patent replaces the mechanical physical device (USB token, mobile device) with a biological system - the user's own body (vein pattern, iris, or fingerprint). This substitution eliminates the need for external physical authentication devices while maintaining security, as the biological characteristics are inherently tied to the user and cannot be lost or damaged in the same way physical devices can.
Solution Approach 2:
The user's own body serves as the authentication device. The vein pattern, iris, or fingerprint that naturally exists on the user is utilized for authentication, eliminating the need for separate physical authentication devices. The body itself becomes both the credential and the authentication mechanism.
2Reliability
If two-step authentication with physical devices is implemented, then authentication security is improved, but system complexity and cost increase due to additional hardware requirements
Solution Approach 1:
The user's body performs multiple functions: it is both the credential storage medium (containing the unique biological characteristics) and the authentication device (where the scanner reads the characteristics). This eliminates the need for separate hardware tokens, mobile devices, or other external authentication devices, simplifying the overall system architecture.
Solution Approach 2:
The biological characteristics naturally present on the user's body serve as the authentication credential, eliminating the need for manufactured physical authentication devices. The body itself provides the security credential without requiring external hardware.
3Ease of operation
If passwords are used for authentication, then ease of operation is improved, but security deteriorates due to passwords being easily forgotten, guessed, or compromised
Solution Approach 1:
The patent replaces the information-based authentication (passwords that can be forgotten or guessed) with biometric authentication using physical characteristics of the body (vein patterns, iris structures, or fingerprints). These biological characteristics are difficult to replicate or forge, providing enhanced security while maintaining ease of use through automatic recognition.
Solution Approach 2:
The user's own body characteristics serve as the authentication credential, eliminating the need to memorize or manage passwords. The biological traits are inherently tied to the user and automatically recognized by the scanner.
Applied Scientific Principles

Function Achieved in This Case
This method provides a secure and reliable user authentication process that enhances transactional security without the need for physical devices or passwords, ensuring a more accurate and efficient identity verification.
Implementation Method 1
a projection component that overlays the authentication image onto a body part of the user
Implementation Method 2
a biometric scanner that reads blood vessel data from a blood vessel on which the authentication image is overlaid
Data Source
AI summary
The innovation discloses systems and methods of authenticating users using vein or blood vessel characteristics. The innovation retrieves, based on an authentication request, an authentication image associated with a user. The authentication image comprises a first predetermined point and a second predetermined point. The innovation projects the authentication image onto a body part of the user and reads a blood vessel from the body part. The user orients the blood vessel such that it corresponds to the predetermined points in the projected authentication image. The user is authenticated when the blood vessel appears to connect the predetermined points in the direction of the blood flow.
