Abstract: The subject disclosure provides systems and methods for providing access to media content from a server based on a user interface of a client device through which the access is requested. A user may access certain media content, such as a song, album, playlist, a radio station, etc., only if a request for that content is initiated via a specific user interface, and when the user is a subscriber to a reduced subscription tier to a service of the server. To restrict the access in this way, an interface-specific token is generated at a server for each media content. The interface-specific token is received by a user device and is used for further access to the media content from the server.

Abstract: A service client on a device can generate an access control identifier using a server seeded and client-specific secret. The device can generate a blinded access control identifier (ACI) using a randomness factor as part of a request message for a blinded ACI signature including authentication data. The device can transmit the request message to a verification server and upon verification receive a blinded ACI signature message that can subsequently be unblinded using the randomness factor to obtain the ACI signature. The device may send the ACI and the ACI signature to a verification server and after verifying the signature receive a service token. The device may transmit the service token to a service provider server requesting access to the service. When a rate associated with the service token is below a threshold rate, the device can access the service provided by the service provider service.
