There is an interesting panel to open the Microsoft faculty research summit featuring Rick Rashid, Daniel Reed, Ed Felten, Howard Schmidt, and Elizabeth Lawley. Lots of interesting ideas, but one that got thrown out was the recent idea that maybe the world does only need five (cloud) computers. If something like this really does happen, then perhaps we’ll need to think even more aggressively about the information sharing issues — is there some way for me to make sure that I only share with (say) Google’s cloud the things that are absolutely needed. Once I have given some information to Google, can I still retain some control over it. Who owns this information now? If I do, how do I know that Google will honor whatever commitments it makes about how it will use or further share that information ? We’ll be exploring some of these questions in our “Assured Information Sharing” Research. Some of the auditing work that MIT’s DIG group has done also ties in .
