Blockchain Wallet Two-Factor Authentication
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current two-factor authentication methods, such as biometric authentication, are susceptible to data breaches, expensive, and invasive, while traditional username and password combinations are easily compromised, lacking sufficient security for digital asset management systems like cryptocurrencies.
Innovation Solution
Implementing a blockchain wallet-based two-factor authentication system that utilizes a private key associated with the user's wallet for secure authentication, where the user signs a message with their private key, providing an additional layer of security and efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If biometric authentication is used for two-factor authentication, then authentication security is improved, but system cost and privacy invasion increase
Solution Approach 1:
The system uses the user's existing wallet and private key to perform authentication, eliminating the need for additional biometric hardware or services. The wallet itself serves as the authentication mechanism, making the system self-sufficient and cost-effective while maintaining security.
Solution Approach 2:
The patent extracts the authentication function from complex biometric systems and relocates it to the wallet's private key. By taking out the authentication mechanism and implementing it through cryptographic signing in the existing wallet, the system reduces complexity and cost while maintaining security.
2Reliability
If biometric authentication is used for two-factor authentication, then authentication security is improved, but privacy invasion increases
Solution Approach 1:
The authentication process uses the user's own wallet and private key without requiring external biometric data collection or processing. This self-service approach eliminates privacy invasion by keeping all authentication data local to the user's device and wallet.
Solution Approach 2:
The patent converts the potential harm of data breaches affecting biometric information into a benefit by using cryptographic signatures that cannot be stolen or replicated. The private key remains secure in the user's wallet, and the authentication process creates a verifiable signature without exposing sensitive data.
3Ease of operation
If traditional username and password authentication is used, then ease of operation is maintained, but authentication security deteriorates
Solution Approach 1:
The system changes the authentication parameter from human-memory-based credentials (usernames and passwords) to cryptographic parameters (private keys and digital signatures). This parameter change maintains ease of operation through automated wallet integration while dramatically improving security through mathematical cryptography.
Solution Approach 2:
The patent replaces the mechanical human-memory system of usernames and passwords with a cryptographic system using private keys and digital signatures. This substitution eliminates the vulnerabilities of traditional authentication while maintaining user convenience through automated wallet integration.
4Reliability
If blockchain wallet-based authentication is implemented, then authentication security is improved, but device complexity increases
Solution Approach 1:
The wallet serves multiple functions: it stores digital assets, manages private keys, and performs authentication. By making the wallet universal and multi-functional, the system avoids adding separate authentication infrastructure, thereby improving security without proportionally increasing complexity.
Solution Approach 2:
The patent merges the authentication function with the existing wallet infrastructure. Instead of adding a separate authentication system, the private key and digital signature capabilities already present in the wallet are utilized for authentication, combining multiple functions into a single system.
Data Source
AI summary
Methods, systems, and devices for using a blockchain wallet for two-factor authentication are described. A custodial token platform implements a two-factor authentication process using a wallet to facilitate verifying a user identity accessing an application or service. The platform receives, from a client application on a user device, an authentication request that is associated with a first user account. The platform transmits a response indicating that a wallet authentication procedure is enabled and the response may include a wallet address. The platform receives a challenge request that includes the wallet address. The platform transmits a challenge response that includes a data payload to be signed using a private key associated with the wallet address. The platform receives a signed response message. The platform verifies that the signed response message is validly signed, and the platform transmits an indication that the signed response message is validly signed.
