Hardware Device ID Verification for Online Transaction Security
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Online credit card transactions lack robust verification mechanisms, making them susceptible to fraud as they rely solely on card information without physical possession or signature verification, leading to potential unauthorized use.
Innovation Solution
Incorporating hardware-based verification by associating a unique hardware device ID with a payment account, where the device provides a non-modifiable identifier during transactions, which is verified by the credit card issuer to ensure the transaction is authorized.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If online transactions rely solely on card information (number and CVV code) for verification, then the transaction process is simple and fast, but the security is insufficient and susceptible to fraud
Solution Approach 1:
The patent introduces a hardware device as an intermediary between the user and the payment system. This hardware device stores the payment account information and provides additional verification through hardware-specific identifiers (such as device ID or serial number). The hardware device acts as a mediator that prevents direct exposure of sensitive card information while adding a layer of security through physical possession requirement and hardware-bound encryption keys.
Solution Approach 2:
The system performs preliminary binding between the payment account and the hardware device during an enrollment phase before actual transactions occur. This preliminary action establishes cryptographic relationships and stores binding information in advance, so that during transactions, only verification is needed without complex real-time setup. The hardware device is pre-configured with unique identifiers and cryptographic materials that will be used for subsequent transaction verification.
2Reliability
If hardware-based verification is added to online transactions, then fraud risk is reduced and security is enhanced, but the transaction process becomes more complex
Solution Approach 1:
The hardware device automatically performs verification functions without requiring active user intervention during transactions. The device self-manages cryptographic operations, generates appropriate responses based on transaction requests, and communicates verification status to the payment system. This self-service capability reduces the operational burden on users while maintaining strong security controls through automated hardware-based verification.
3Reliability
If encrypted tunnels and secure pages are used for transmitting payment information, then data transmission security is improved, but the system remains vulnerable to fraud since card information can still be stolen
Solution Approach 1:
The patent adds a new dimension of security verification by incorporating hardware-specific identifiers and physical possession requirements beyond traditional card information. Instead of relying solely on protecting card data transmission, the system verifies the physical hardware device itself through unique identifiers and hardware-bound cryptographic keys. This dimensional shift from protecting data in transit to verifying the authenticity of the requesting device fundamentally changes the security model.

AI summary
A method, program and system are provided for securing electronic transactions. A payment card processor server computer receives a payment authorization request message, the payment authorization request message being generated in response to an electronic payment transaction request made by a user, wherein the payment authorization request message includes first encrypted payment account information for a first payment device. The payment card processor server computer receives a first hardware device ID associated with a first hardware device that generated the payment authorization request message, wherein the first hardware device is associated with a user payment account for the user. The server computer determines that the first encrypted payment account information from the received payment authorization request message matches the first hardware device ID, and the purchase request is completed.
