Browser Extension Secure Tokens for Authenticated Payment Autofill

The patent introduces secure tokens as an intermediary between user data and payment fields. Instead of directly submitting sensitive user data, the browser extension generates secure tokens that act as mediators - these tokens contain encrypted references to the actual data and can only be used for their intended purpose, thereby protecting the original data from interception and fraud while maintaining automatic population functionality

The patent segments the authentication process into distinct components: token generation, token validation, and data submission. The browser extension handles token generation and submission, while a separate authentication service validates the tokens. This segmentation allows each component to be optimized independently and reduces the complexity burden on any single device

The patent implements preliminary authentication by requiring users to authenticate once when initially setting up their browser extension with their payment information. This preliminary action stores authentication credentials locally, eliminating the need for repeated authentication during subsequent transactions. The secure tokens generated from this preliminary authentication can be automatically submitted without requiring additional user intervention, thus maintaining both security and productivity
