Methods and systems for delivering secure services or content to non-subscriber identity module (sim)-based endpoint clients

Abstract

A method comprising receiving incoming data destined to a line associated with a user, determining a security parameter associated with the incoming data based on at least one of a source of the incoming data or a content of the incoming data, in which the security parameter indicates a security level of the incoming data, storing, in a second data store accessible to the data application, the incoming data in association with the security parameter, receiving a sync request for the incoming data comprising an access token indicating an authentication type associated with a second factor of authentication used to authenticate the client with an authorization server, transmitting the incoming data to the client when the client is permitted to retrieve the incoming data from a data store.
