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.

Abstract: In some embodiments, a first electronic device shares a portion of a content item corresponding to a respective portion of lyrics for the content item with a second electronic device. In some embodiments, a system facilitates securely sharing a portion of a content item between two devices. In some embodiments, an electronic device generates a server address for accessing a portion of a content item. In some embodiments, a uniform resource locator includes an identification of content, an indication of a first subset of the content, and authentication data.

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: Techniques for suggesting media assets, the technique including: requesting a set of candidate media assets for a set of user media items based on a knowledge graph metadata network describing the set of user media items; receiving metadata for the set of candidate media assets; determining one or more sets of ranked media assets based on the received metadata; and outputting the determined one or more sets of ranked media assets.

Abstract: In some implementations, a computing device can receive a display list that describes software applications to install and/or represent on a user interface of the computing device. The display list can specify software applications that the computing device should automatically download and install. The display list can specify an order for presenting or arranging representations of the software applications on the user interface of the computing device. The computing device can determine which system applications to hide based on the absence of a system application in the display list. In some implementations, a computing device can receive a hide list that describes software applications to hide from view on the user interface of the computing device. The hide list can specify software applications that are installed on the computing device but that should not be presented or represented on the user interface of the computing device.
