Dynamic Gesture Authentication Using Real-Time Image Analysis
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current authentication techniques for mobile devices and online transactions are vulnerable to fraudulent activities due to the discoverability and replicability of passwords and biometric information, and lack real-time verification, allowing fraudulent use of authentication data.
Innovation Solution
A system and method for authenticating users based on real-time image data captured using a device's image sensor, which includes analyzing biometric information and a dynamically performed gesture to verify user identity and ensure the authenticity of the authentication data.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If password or biometric authentication is used, then authentication convenience is improved, but security against fraudulent activities deteriorates
Solution Approach 1:
The patent introduces dynamic authentication parameters that change over time, such as time-limited authentication tokens and session-based credentials. This dynamic approach ensures that even if authentication data is compromised, it cannot be reused for fraudulent transactions after the time window expires, thereby maintaining both convenience and security
Solution Approach 2:
The system performs preliminary authentication actions by capturing and verifying biometric data (such as facial recognition or iris scans) before allowing access to banking functions. This preliminary verification ensures that the user is physically present and authentic before any transaction occurs, preventing fraudulent use of stolen credentials
2Reliability
If real-time image capture is implemented, then authentication security is improved, but system complexity increases
Solution Approach 1:
The patent leverages the existing multi-functional capabilities of mobile devices, using the camera for both standard photography and security authentication purposes. The same image sensor and processing unit serve multiple functions, reducing the need for dedicated hardware and minimizing system complexity while maintaining high security standards
Solution Approach 2:
The system uses the device's own resources (camera, processor, stored biometric templates) to perform authentication without requiring external specialized equipment. The mobile device autonomously captures images, processes them through algorithms, and compares them against stored data, making the system self-sufficient and reducing overall complexity
Data Source
AI summary
Systems and methods are provided for authenticating a user of a computing device. The system comprises one or more memory devices storing instructions, and one or more processors configured to execute the instructions to provide, to a computing device associated with a user, an indication of a prescribed authentication parameter. The system also receives image data including an image of the user of the computing device captured using an image sensor of the computing device. The system determines an identity of the user based on an analysis of the received image data, determines whether the received image data includes a feature corresponding to the prescribed authentication parameter, and authenticates the user based at least in part on whether the received image data includes the feature corresponding to the prescribed authentication parameter.
