US Patent 12008551 Layered security for age verification and transaction authorization

A user may be willing to purchase items or participate in a pay-for service offered by a service provider. A service provider may wish to verify characteristics of the user prior to allowing transactions to take place, and may want to secure the transactions once the transactions are allowed. A credential issued to a user and a transaction application uploaded to a user device may be used to secure transactions between the user and a service provider interface, such as a webserver or a point-of-sale. The transaction application may capture real-time user data and comparing the real-time user data to prior user data stored on the credential, authenticate the service provider interface to the user and the user to the service provider interface; and establish an encrypted session between the service provider interface and the transaction application adapted to authenticate the transactions between the user and the service provider interface.
