Publication number: 20230080210Abstract: 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.Type: ApplicationFiled: January 31, 2022Publication date: March 16, 2023Inventors: Betim DEVA, Mufaddal Y.
