The granted patent (Publication Number: US11870769B2) discloses a computer-implemented method for identifying a browser instance executing on a user computing device. The method involves obtaining a private key and a public key unique to a combination of the web domain and the browser instance, storing the private key in a secure manner within the browser instance, generating a challenge response using the private key, and transmitting the response to the server for validation. Additionally, the method includes receiving executable code from the server to automatically obtain the key pair web cryptography application programming interface without user input, using the private key in challenge-response with the server to identify the browser instance in subsequent sessions, and obtaining a browser certificate for identification purposes.

Furthermore, the patent describes a system for identifying a browser instance, comprising a user computing device and a server hosting the web domain. The system involves the user computing device obtaining and storing the private key securely, generating a challenge response using the private key, and transmitting it to the server for validation. The server provides instructions to the browser instance for obtaining and storing the key pair, registering the browser instance for secure transactions, and validating the browser certificate. The patent also includes a computer program product for performing the steps of the method at the browser instance in a browser session between the server and the browser instance, ensuring secure identification and communication between the two entities.
