Abstract
A helper SDK embedded in a native application performs local operations on behalf of a web application affiliated with the helper SDK. The helper SDK may perform security functions such as fingerprint or face biometric verifications as well as access device-specific hardware such as a camera or secure memory. The web application may use an 0Auth technique for access and refresh tokens. In a transaction system, when a user is confirmed via the security function, order details are passed to the web application with a refresh token and ciphertext confirmation data is returned to the native application for completion of the transaction.
