Card Feature Verification for Online Identity Security

Resolve Bottlenecks,
Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing identity verification systems for online transactions relying on 'card number+password' combinations are insecure, as they can lead to unauthorized access and monetary loss due to potential misuse of card information.

Innovation Solution

A system that verifies user identity by comparing features of a card image, including number, pattern, material, and graphic features, using image processing techniques to ensure only the legitimate card holder can perform transactions.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If card number and password are used for identity verification, then the verification process is simple and convenient, but security is compromised due to potential unauthorized access

Engineering Contradiction:

Improveverification process simplicityVSAvoididentity verification security

Core Design Contradiction:

Ease of operationVSReliability

Solution Approach 1:

The patent uses optical copying technology to capture images of the card front and back surfaces, extracting visual features (patterns, colors, layouts) to create a digital representation of the physical card. This copying approach enables verification without exposing sensitive card numbers or passwords, maintaining both convenience and security.

Inventive Principle:

Principle #26Copying

Solution Approach 2:

The patent introduces visual feature extraction as an intermediary layer between the user and the verification system. Instead of directly using card numbers and passwords, the system extracts and compares visual features from card images, serving as a secure mediator that prevents direct exposure of sensitive information while enabling verification.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Productivity

If card information is transmitted through the network, then transaction processing is enabled, but unauthorized access and information theft risks increase

Engineering Contradiction:

Improvetransaction processing efficiencyVSAvoidunauthorized access risk

Core Design Contradiction:

ProductivityVSObject-affected harmful factors

Solution Approach 1:

The patent extracts only the necessary visual features (patterns, colors, layouts) from the card images for verification purposes, leaving sensitive information such as card numbers and personal details on the user's device. This extraction principle minimizes network transmission of sensitive data while enabling transaction processing.

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

The patent uses disposable, non-sensitive visual feature data for verification instead of reusing sensitive card information. The visual features act as single-use verification tokens that do not need to be protected long-term, reducing the risk associated with network transmission and storage of sensitive data.

Inventive Principle:

Principle #27Cheap short-living objects (Disposable)

AI summary

One embodiment of the present invention provides a system that facilitates identity verification based on various features of a card. During operation, a server receives a request for identity verification, where the request corresponds to an account and includes an image of a verifiable card. The server extracts a card feature from the verifiable card image for use as a verifiable card feature. In response to determining that the verifiable card feature matches a corresponding card feature of a registered card of the account, the server determines successful identity verification.
