... and encryption really shouldn't slow anything down unless you've got an insane-speed internet connection :)

Wouldn't the act of encryption slow things down?  i.e. step 1 encrypt, step 2 upload instead of just step 1 upload?
A fast consumer internet connection has 100kb/s upload rate. A 3 year old dualcore laptop can do ~140mb/s AES encryption :)


I've asked Dropbox support if their FAQ statement that says that "Dropbox employees aren't able to access user files" were really true. Their response:

Quote
Yes. Dropbox employees can't access the file's contents. They can see the file names, move, delete or even restore files, but can't view them. The only exceptions are the executive staff who have a vested interest the company.

I have to admit that I am shocked about their slack interpretation of the word "employee". To be honest, I feel cheated by that FAQ statement. Already the fact that any employee could actually delete my files is unbelievable.

Thanks for sharing that, phitsc.
It seems very wrong. Even if their definition of employee wasn't slack...

This:

makes this:

"Dropbox employees aren't able to access user files"

a lie.

Try telling the IRS that any executive staff, whether or not they are officers of the corporation, whether or not they own stock or have any other vested interest, are not employees of the corporation.

Damn, it took me about 10 seconds to see that. And it's only 4 letters ;)

...there's more in the blog article the quote is from.

Thanks for the link [Edit : Dropbox's lawyers should study it too]. And I'm also going to study that spideroak thing a bit more though before I Drop or prod the box.... which is definitely something I'll do. Just a matter of time.

This is a pretty good and balanced general article : http://web.appstorm....ak-file-sync-battle/

It mentions security, but isn't focused on it.

And the website is also not bad at all... first time I see it.

More on Dropbox security.
In addition to those security concerns, also keep this in mind:

shot-17-04-2011@14_57_47.png...in other words, if somebody gets access to your hostid, changing you password isn't going to matter the tiniest bit in the world.

And then we've got this:
Business Transfers. Dropbox may sell, transfer
    or otherwise share some or all of its assets,
    including your Personal Information, in connection
    with a merger,  acquisition, reorganization or
    sale of assets or in the event of bankruptcy.
...all your data are belong to us. Might be standard business practice, but is it particularly confidence-inspiring?

Really, start the DropBox exodus already.

Thanks for the links -- am having problems with the first one though. Installed spideroak last night and will experiment with it today.

Even if I don't have much sensitive stuff in my dropbox account, it's a question of principle: companies offering "cloud" storage should take privacy more seriously. With all that, Dropbook is starting to look like Facebox.

Would it be unethical to ask SpiderOak for a special donationcoder discount ? I read quite a bit about it and I think they really have a good product. IMO, it's the perfect alternative to DropBox. Especially if the later doesn't put its act together.

Well, they said :

Yes. Dropbox employees can't access the file's contents. They can see the file names, move, delete or even restore files, but can't view them. The only exceptions are the executive staff who have a vested interest the company.

... but, to know how they do it... they'd have to tell us exactly.

Given what we've heard about DropBox, the "how do the executives bypass security" is probably as simple as "grantAccess = (user.isExecutive == true);"

But if the data is supposed to be encrypted by a private key ...

Who are the 'executive staff' andc how do they bypass their own security system?

I would assume that it means executive staff have access to the private keys they use for encryption.

Even if I would trust these executive staff (whoever and however many that are), the problem is that if they have access to my data, then a not properly fixed or yet to be discovered security problem on their servers could possibly make my data available to hackers as well.

I like it how SpiderOak tries to be very clear about where possible security problems in using their service could be, e.g. here about accessing one's data over the web interface:

Zoiks! ...So apparently, at this point, it's safer to have your head in the sand, than in the cloud(s).

Wonder what DropBox is going to do now. There might be lawsuits coming.
