Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current contactless transaction systems face inefficiencies in authentication processes, leading to increased overhead and processing time due to the need for multiple proprietary verification algorithms, which complicate user identity verification across different platforms.
Innovation Solution
A system utilizing a blockchain distributed network to enable contactless access to transaction terminals by using a unique identifier associated with user devices, which reflects authentication credentials, and a distributed ledger for validating these credentials through a smart contract logic, reducing the need for multiple proprietary verifications.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple proprietary verification algorithms are used for authentication, then security is improved, but processing time and system complexity increase
Solution Approach 1:
The patent implements a universal blockchain-based authentication system that serves multiple verification functions across different platforms. The distributed ledger provides a single authoritative source for authentication credentials that can be validated by any transaction terminal in the network, eliminating the need for each platform to maintain separate proprietary verification algorithms. This multi-functional approach maintains security while reducing processing time through centralized verification.
Solution Approach 2:
The blockchain network acts as an intermediary layer between user devices and transaction terminals. Instead of direct verification between multiple proprietary systems, the blockchain serves as a neutral mediator that provides cryptographic proof of authentication credentials. This intermediary approach streamlines the verification process by replacing multiple sequential verification steps with a single blockchain-based validation, reducing overall processing time while maintaining security.
2Reliability
If multiple proprietary verification algorithms are used for authentication, then authentication security is improved, but device complexity increases
Solution Approach 1:
The blockchain authentication system provides a universal verification mechanism that replaces multiple proprietary algorithms with a single standardized protocol. All transaction terminals in the network use the same blockchain-based verification method, eliminating the need to maintain and manage multiple different verification systems. This reduces device complexity by standardizing the authentication approach across the entire network while preserving security through cryptographic validation.
Solution Approach 2:
The patent extracts the authentication verification function from individual transaction terminals and relocates it to the blockchain network. Instead of each terminal maintaining its own proprietary verification algorithms, the complex verification logic is extracted and embedded in the blockchain's distributed ledger and smart contracts. This extraction reduces the complexity burden on individual devices while centralizing the security-critical verification functions in the blockchain infrastructure.
3Productivity
If contactless access is implemented without blockchain validation, then processing speed is improved, but authentication reliability decreases
Solution Approach 1:
The system performs preliminary authentication actions by storing validated credentials in the blockchain distributed ledger before actual transactions occur. User authentication credentials are verified and recorded in advance on the blockchain, creating a trusted baseline. During contactless transactions, terminals only need to verify against this pre-established blockchain record rather than performing full authentication, thus maintaining high transaction throughput while ensuring authentication reliability through the preliminary validation stored on the immutable ledger.

AI summary
Systems, computer program products, and methods are described herein for a system to enable contactless access to a transaction terminal using a process data network. The present invention is configured to electronically receive from a transfer terminal, an indication that a user is accessing the transaction terminal using a user device; retrieve, from the user device, a unique identifier associated with the user device; compare the unique identifier with a block chain of authentication information associated with the user to determine whether the unique identifier meets a condition associated with the block chain authentication information; receive an indication that the unique identifier meets the condition of the block chain thereby validating user identity; and allow the user to access the transaction terminal based on at least receiving the indication that the unique identifier meets the condition of the block chain.
