Users can share information, but the network only sees encrypted data.

Researchers at Microsoft have developed mobile social networking software that lets users share personal information with friends but not the network itself.

When a Contrail user updates his information on the network, by adding a new photo, for example, the image file is sent to a server operating within the networks' cloud, just as with a conventional social network. But it is encrypted and appended with a list that specifies which other users are allowed to see the file. When those users' devices check in with the social network, they download the data and decrypt it to reveal the photo.
