Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing multi-factor authentication (MFA) systems for online non-face-to-face transactions face challenges such as data breaches, inability to authenticate clients with full confidence, vulnerability to man-in-the-middle attacks, and the need for physical presence for transaction execution, which compromises security and convenience.
Innovation Solution
The use of Blockchain technology, Digital Certificates, and live video clips, combined with Biometric and Biographical data, to create a secure authentication process through the Data Analytics Authentication Processor (DAAP), ensuring data immutability and integrity, and enabling machine-to-machine transactions without human intervention.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If multi-factor authentication systems are used for online non-face-to-face transactions, then transaction convenience is improved, but security and reliability deteriorate due to data breaches and man-in-the-middle attacks
Solution Approach 1:
The authentication system is segmented into multiple independent verification components: biometric data verification, biographical data verification, blockchain transaction verification, and digital certificate verification. Each component operates independently and contributes to the overall authentication decision, preventing single-point failures and enhancing security without compromising convenience
Solution Approach 2:
A trusted third-party verification system is introduced as an intermediary between the client and service provider. This intermediary uses blockchain technology and digital certificates to mediate the authentication process, verifying client identity without requiring physical presence while maintaining high security standards through multiple verification layers
2Reliability
If physical presence is required for transaction execution, then authentication reliability is improved, but transaction convenience and speed deteriorate
Solution Approach 1:
The mechanical requirement of physical presence is replaced with electronic verification mechanisms. Biometric data (fingerprint, facial recognition), digital signatures, and blockchain-verified credentials substitute for physical appearance, maintaining authentication reliability while enabling remote non-face-to-face transactions
Solution Approach 2:
The authentication parameters are changed from physical presence verification to digital credential verification. The system verifies identity through biometric templates, cryptographic signatures, and blockchain-recorded credentials rather than requiring the client's physical appearance, thus maintaining security while enabling remote transactions
3Device complexity
If traditional data storage methods are used, then system simplicity is maintained, but data security and integrity deteriorate due to vulnerabilities to hacking and data breaches
Solution Approach 1:
The system transitions from traditional single-dimension data storage to multi-dimensional verification by integrating blockchain technology. Client credentials are stored and verified across distributed blockchain ledgers, adding a new dimension of security through cryptographic hashing and distributed consensus, which prevents hacking and data breaches while maintaining operational simplicity
Data Source
AI summary
This invention describes a method, and an apparatus for identifying and authenticating an Individual Client (IC), or a Secure-Computing-Device online while ensuring the privacy of the IC's personal data, (IPD), and information against identity theft and fraud by using a combination of prior art Blockchain technology, public key cryptography, and a newly created Biometric Digital Certificate issued by an accredited Biometric Certification Authority. The IC's transactions data are dynamically updated, cryptographically signed for integrity and stored in an immutable blockchain each time the IC requests service from a Service Provider and provides an accurate and traceable audit trail. During online access, the IC transactions data stored in the Blockchain Databases are processed by a Data Analytics Authentication Processor to generate the Service-Access-Authentication-Tag, which is an algorithmic score that determines the IC's eligibility to access online services offered by a plurality of Services Providers.
