Overview
As digital interactions become increasingly prevalent, the demand for secure and efficient authentication methods intensifies. Traditional authentication mechanisms are fraught with vulnerabilities, while centralized storage solutions pose significant security risks. Biometric authentication, specifically facial recognition, provides a higher security level by utilizing unique physiological characteristics. Integrating this with the Internet Computer—a decentralized blockchain network—introduces benefits like scalability, speed, and enhanced security.
This paper outlines a project that implements a biometric face authentication service hosted on the Internet Computer. The service uses person IDs and webcams to authenticate users and is designed for integration by other services requiring secure user verification.
Problem Statement
We introduce a blockchain-based biometric face authentication service built on the Internet Computer, a decentralized platform developed by the DFINITY Foundation. The service utilizes person identification (ID) and webcam technology to ensure secure and decentralized identity verification. By harnessing the capabilities of the Internet Computer, this system offers improved scalability, speed, and security compared to traditional blockchain platforms. Designed for seamless integration, this authentication service caters to various applications and services that require reliable user verification while maintaining security and user privacy.
As digital interactions become more common, the need for secure and efficient authentication methods grows. Traditional authentication methods often come with vulnerabilities, and centralized storage solutions can pose significant security risks. Biometric authentication, particularly facial recognition, offers a higher level of security.
Scalability Limitations
Traditional blockchains struggle with scalability and speed, leading to latency issues in real-time applications.
Security Vulnerabilities
Centralized authentication systems are susceptible to data breaches and single points of failure.
Privacy Concerns
Users are wary of how their biometric data is stored and used, fearing unauthorized access and misuse.
Integration Challenges
Existing systems lack interoperability, making it difficult for services to adopt new authentication methods seamlessly.
Benefits of using Internet Computer (IC)
Utilizes the Internet Computer
Leverages its high throughput and low latency for real-time authentication.
Employs Biometric Facial Recognition
Users authenticate using facial biometrics captured via webcams.
Implements Decentralized Identifiers (DIDs)
Users control their digital identities without centralized authorities.
Ensures Privacy and Security
Biometric data is encrypted and stored securely, with references on the Internet Computer.
Provides Seamless Integration
Other services can easily integrate the authentication mechanism via APIs.
