Identity-Storing Browser with Blockchain Transaction Verification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Online and mobile transactions are vulnerable to fraud due to the risk of sensitive user data misappropriation, making it difficult for both consumers and merchants to ensure security and legitimacy during electronic transactions.
Innovation Solution
An Internet browser that encrypts and stores user identity and financial information using PINs, biometric data, and other security measures, authenticates users before transactions, and records transactions on a blockchain for transparency and security.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If sensitive user data is communicated and stored electronically to enable online transactions, then transaction convenience and speed are improved, but the risk of data misappropriation and fraud increases
Solution Approach 1:
The patent extracts sensitive user data from traditional centralized databases and stores it distributed across multiple nodes in a blockchain network. This removes the single point of failure and reduces the risk of data misappropriation while maintaining transaction speed through efficient cryptographic operations and consensus mechanisms.
Solution Approach 2:
The patent introduces blockchain technology as an intermediary layer between users and merchants. This mediator provides transparent, immutable transaction records that verify legitimacy without requiring users to share sensitive data directly with merchants, thus reducing fraud risk while enabling fast transactions.
2Reliability
If consumer personal and financial information is shared with merchants for transaction verification, then transaction legitimacy can be verified, but consumer privacy and security are compromised
Solution Approach 1:
The patent segments transaction verification into two independent components: (1) identity verification through blockchain-based digital identities that prove legitimacy without revealing personal information, and (2) transaction authorization through cryptographic signatures. This allows merchants to verify transaction legitimacy while consumers maintain privacy control over their personal and financial data.
Solution Approach 2:
The patent creates cryptographic copies of transaction authorization rather than sharing original sensitive data. Merchants receive verified transaction tokens that prove legitimacy without containing actual personal or financial information, thus maintaining verification reliability while protecting consumer privacy.
3Ease of operation
If traditional electronic storage methods are used for user data, then data accessibility and transaction processing are simplified, but security vulnerabilities and fraud exposure increase
Solution Approach 1:
The patent transitions data storage from a traditional two-dimensional model (centralized database with user-merchant access) to a multi-dimensional distributed ledger structure. Data is stored across multiple blockchain nodes with access controlled through cryptographic keys and smart contracts, maintaining ease of operation through standardized APIs while dramatically improving security through distributed redundancy and immutability.

AI summary
A method includes: communicating data from a browser, operating on a computing device, to an electronic shopping cart during a transaction; receiving user-authenticating data from a user interface of the computing device; decrypting secure user data stored to the computing device; authenticating a user based on the user-authenticating data and the decrypted secure user data; in response to authenticating the user, transmitting an indication of payment from the browser to the electronic shopping cart; processing the transaction after transmitting the indication of payment; and recording the transaction in a blockchain stored on the computing device.
