Abstract

A device streams assets to network-based storage, and servers administering the network-based storage operate to notify other authorized devices that the assets are available to download, including initiating the download of assets automatically or in response to user input. With streaming enabled on their device, a user is able to make assets, such as digital photograph, video or other type of media file, data file, or other type of electronic content, available immediately to all of their other devices and to other users having permission to follow assets streamed by their device. Servers secure access to the stream of assets, on both an account level and an asset level in accordance with asset metadata registered for the assets during streaming.
