Transaction Security via Obscured Challenge Statements
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current security mechanisms for conducting transactions over non-secure channels, such as the Internet, are vulnerable to hacking systems that can intercept, modify, or substitute transaction data, and existing authentication methods are insufficient to prevent such threats.
Innovation Solution
A system and method that involves generating a customized statement incorporating transaction information and a challenge, which is obscured to prevent crimeware from deciphering or responding, requiring human users to verify the information through a correct response to ensure the authenticity of transactions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional authentication methods are used, then ease of operation is maintained, but security reliability deteriorates due to vulnerability to hacking systems
Solution Approach 1:
The patent introduces an intermediary verification mechanism where a challenge statement is generated and presented to the user. This intermediary element (the challenge-response system) acts as a mediator between the authentication system and the user, adding a security layer that prevents automated hacking while still allowing legitimate users to complete authentication. The challenge statement serves as a bridge that translates security requirements into user-friendly verification.
Solution Approach 2:
The patent dynamically changes authentication parameters by generating unique challenge statements for each transaction. Instead of using static authentication credentials, the system varies the challenge parameters (different statements, different verification requirements) for each authentication event, making it difficult for hackers to use automated attacks while maintaining ease of use for legitimate users who can adapt to the challenges.
2Ease of operation
If transaction information is transmitted over non-secure channels, then ease of operation is improved, but security reliability deteriorates due to interception and modification risks
Solution Approach 1:
The patent applies preliminary action by generating and presenting the challenge statement to the user before the actual transaction is completed. This preliminary verification step ensures that the user confirms the transaction details in advance, preventing hackers from intercepting and modifying transaction information without detection. The challenge-response mechanism is executed beforehand to validate user intent before sensitive operations proceed.
3Reliability
If authentication mechanisms are strengthened, then security reliability is improved, but device complexity increases
Solution Approach 1:
The patent implements self-service by requiring the user to read and verify the challenge statement themselves, rather than relying on complex automated verification systems. The user's own reading and comprehension abilities serve the authentication function, eliminating the need for sophisticated biometric scanners, hardware tokens, or complex cryptographic protocols. The system leverages the user's inherent capabilities to provide security without adding device complexity.
Data Source
AI summary
A system and method of conducting a transaction comprising accepting transaction information from a user, producing a customized statement, the customized statement relating to at least a portion of the transaction information and including a challenge to the user, and sending the user an obscured representation of the customized statement. The system and method may accept from the user a response to the challenge. The system and method may further allow the transaction to proceed if the response is correct and prevent the transaction from proceeding if the response is incorrect.
