  • Patent number: 11204729
    Abstract: Internet based digital content services, and mobile devices accessing the Internet based digital content services, are herein disclosed and enabled. The digital content services provide encrypted digital content to the mobile devices for ensuring security of the digital content. The encrypted digital content is device dependent to render at a specific device. In an example, a user of the mobile device may access the digital content at a digital content service by providing appropriate authentication or subscription information to the digital content service. Based on successful authentication, the user may select digital content from one or more digital content provided by the service. The service then generates encrypted output data that is based on the selected digital content and transmits the output data to the mobile device. The generated output data is device dependent and is rendered at specific devices, including the mobile device and output devices.

  • Patent number: RE49176
    Abstract: Anonymous voice communication between a first station and a second station is facilitated by providing an interface that allows input of a transaction specification from at least one of the first and second stations. A reference code associated with the transaction is generated, there being a defined relationship between the reference code and the address of the second station for voice communication. The reference code is supplied to the first station, and a voice communication request and the reference code are received from the first station. The reference code is used to recover said address and a channel for voice communication is opened between said first and second stations. Voice communication can thereby be established between the first and second stations without providing the address of the second station to the first station.An Internet-based service system for data mining user information is herein disclosed and enabled.
