What are the security and privacy implications of these trends?
• Privacy – companies know a lot about us• Data security – a security breach exposes all our data

05 Case Study
Centralized Trust 3rd Parties lets you store your private data in their storage.
– Certificate Authority(or bank and etc) has ‘master key’ so can decrypt all your data.
– A bug or security breach in C.A can expose all your data.
– Suffer possible corruption of 3rd parties
05 Case Study
DropBox lets you store your files in the cloud.
• For efficiency reasons, if 2 or more members have the same file , DropBox doesn’t want to store it twice.
• For security reasons, it’d be nice if DropBox could encrypt your files on your computer (with a key only you know) and upload the encrypted version.
• In fact, on 6/19/2011, DropBox did have a bad bug, where they screwed up the authentication: you could log into someone else’s account without knowing their password (just enter any password, and you’re in). This exposed everyone’s files to the world.
