Biometric Auto-fill for Secure Online Transactions
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing secure information retrieval systems for online transactions, such as credit card information, are vulnerable to misuse due to the lack of robust user authentication, particularly in browser-based auto-filling functions.
Innovation Solution
The method involves using biometric information, obtained through sensors like fingerprint scanners, to verify a user's identity during online transactions, allowing only authorized personal information to be automatically filled into relevant fields, thereby enhancing security and preventing unauthorized access.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If browser auto-filling function is enabled for easy payment transactions, then ease of operation is improved, but security against misuse deteriorates
Solution Approach 1:
The patent introduces biometric authentication (fingerprint sensor) as an intermediary between the user and the auto-filling function. The system requires successful biometric verification before enabling the auto-fill operation, thus mediating access to sensitive credit card information and preventing unauthorized use while preserving convenience for legitimate users
2Reliability
If biometric authentication is added to verify user identity, then security is improved, but device complexity increases
Solution Approach 1:
The system utilizes the device's existing sensor capabilities (fingerprint sensor, camera, microphone) that are already part of modern smartphones and tablets. By leveraging self-service biometric features built into consumer devices, the patent avoids adding external authentication hardware, thus minimizing the increase in device complexity while achieving enhanced security
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This approach significantly reduces the risk of misuse by ensuring that only verified users can access and fill personal information during online transactions, providing a secure and convenient payment process.
Implementation Method 1
obtaining, using a sensor, biometric information of a user of the electronic device
Data Source
AI summary
A transaction method using an electronic device. The method comprises detecting, during an online transaction, one or more fields capable of being automatically filled by the electronic device, the one or more fields associated with the online transaction. The method further comprises obtaining, using a sensor, biometric information of a user of the electronic device, and verifying an identity of the user of the electronic device based on the obtained biometric information. Additionally, the method includes, in response to verifying the identity of the user of the electronic device based on the obtained biometric information: identifying personal information of the user to be automatically filled into the one or more fields based on the verified identity, and inserting the identified personal information into the one or more fields for the online transaction.
