Closed network environments, such as in-flight entertainment (IFE) where users connect their own devices such as smartphones, tablets, laptops, etc. are becoming common. In such environments, playback of protected content on devices is made possible by the presence of streaming and licensing servers that are present within the closed network environment, e.g., aboard a flight. The provisioning server for such content, however, is hosted by a third party and is generally unavailable within the closed environment, which causes playback to fail. This disclosure describes techniques of pre-provisioning without imposing a requirement on the user to download additional applications, such that different content websites get different certificates that don’t cross-reference on the same device. In this manner, protected content is delivered to closed-environment users in a convenient, privacy-preserving manner.
