Great piece - too much absolutism on this topic rather thinking through the real issues.

Dedpulication should only compare file checksums via md5 hash rather than open the file. I certainly learned more about this topic due to the responses.

When moving to the cloud I weighed up Dropbox to similar providers and found their security not meeting my requirements and in the end signed up with SpiderOak who have a zero knowledge privacy policy. Their web UI is a little clunky however

Dropbox checks docs because of the so called deduplication process. It means if you upload anything to their servers, they check it, whether it is up already. If it is, they provide a shortcut to the already uploaded file and delete yours. (eg. this works very well wit videos and music files). it is a common market practice among public cloud providers like Dropbox, Google Drive and so on, even many of those do it, who claimed to be secure (like Wuala). As far as I know dedup. is unavailable by client side encrypted tools, so you can skip all this trouble by using eg. Tresorit. Boxryptor is good to encrypt your dropbox, truecrypt is not really for could it's service focuses on local encryption.

I recommended Boxcryptor or Truecrypt for encryption options. These would be encrypting the file rather than password protecting. I agree with you that file specific passwords may not be the best approach.

Thank you for mentioning the balance regarding the disclosure. It certainly can be difficult to sort through the FUD at times like these.

Stop by a meeting sometime if you're available!

I wonder whether those who sued Google for "reading" their Gmail will now target Dropbox for "reading" text documents?

Haha, except that Word encryption is notoriously flawed (or at least it was in the past). ;-)

For what it's worth, I agree with Laurie - definitely appreciated that you were balanced about the disclosure. Still, you should have seen the press releases that I got from vendors - "this proves, once and for allG«™" Even when you ARE balanced, there's someone out there that isn't.

Correct, they could not be previewed. A key would be needed to decrypt the file and it would not be best practice to store the key in the same location as the encrypted files.

What if you encrypted the Word docs before uploading them to DropBox? Then they could not be previewed, right?

re: Dropbox File Brouhaha: Use Case Is The Issue
Exactly. The explanation of the automated process made sense and it turns out that this applied to any service that offers this browser specific feature. It may be possible that many people (especially users of the desktop client) did not realize what the "effects of rendering low-quality previews" truly meant. Just another piece of info they can use to assess risk.
Other services were tested and no responses were received from the files, so that seemed interesting. A theoretical attack surface was mitigated due to the discussion as well. The follow-up post mentioned encryption options if privacy is a consideration for any service that may offer this feature.
