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.
