Ryan Singel, reporting for Wired’s Threat Level on an FTC complaint against Dropbox by Christopher Soghoian (yes, him again):
Up until April 13, the site promised this:
Dropbox employees aren’t able to access user files, and when
troubleshooting an account, they only have access to file metadata
(filenames, file sizes, etc. not the file contents).
Now the site says:
Dropbox employees are prohibited from viewing the content of files
you store in your Dropbox account, and are only permitted to view
file metadata (e.g., file names and locations).
This won’t keep me from using Dropbox, but there’s a big difference between Dropbox’s original and current descriptions regarding how their encryption works.
