QR Droid can scan codes from your gallery. The option is hidden away in the More menu, but it's there.

I just tried this, and it was easy.

Phone: HTC One X
View image. Press Power and Home at same time to take screen capture. Open Google Goggles and select scan image from album. Select image. Google Goggles scans QR code and gives link to web page.

CSB time. A year ago I installed a new HDD on my PC and when I tried to reinstall Windows got a blue screen and a long error code. Rather than try to write it down I just took a picture with my phone. I put the old drive back in, booted up with the original install of Windows, went to Google to search that code, unlocked my phone....
To find Google Goggles which had been open in the background had already scanned the error message, searched it and already had the link to the MS support page giving details of that error and how to fix it..
Technology scares me sometimes...

Better than password blocking your computer...

Once the screen saver gets deactivated, a QR code shows on the screen with the text "scan this code to continue."

If anyone actually scans the code, it leads to a pic (animated, sound... why not?) of a bunch of people pointing and laughing at them.

Set a secret key combination to turn off QR code screen.
(and block all the other key combos)

How's that?

Guys, what's the big deal about airline food? I find that when I'm on a long flight, I get hungry and really appreciate a meal with a sufficient calorie count and balanced nutritional elements to keep my body functioning at normal capacity. Am I missing the joke somehow?

Good grief, amazing how many people seem downright offended by this one.

Yes, people, it's funny. If you don't think it is, fine - no need to smash heads into pavement over it.

You may reread my post and try again if you'd like. Selectively quoting gives me the impression that you are deliberately misreading me, but I'll allow for the possibility that you cannot process thoughts containing more than ten words.

"..Mobile app user..."

But will it be any better if they put the same garbage into a desktop application installer?

I mean, are you still going to use that application?

Sounds legit. For bonus BOFH points, make sure the displayed code is constantly flipping some of its pixels. For doubleplus evil, change the text to "solve this maze starting from the center in 8 seconds"...

Also - isn't beaniescript in a captcha a bit redundant? Surely you don't mean you can actually read any of the other ones...? *squinting suspiciously* Hmmm, you sure you're not a borg...?

To describe what I was going for, I'll move to a home security analogy....
Someone wanting to get into your house, given enough time, can pick your deadbolt lock.
However, if the deadbolt lock is fake, and FEELS pickable but isn't (one solid pin, maybe), then it will take a LOT of time.
(especially if there is a real deadbolt on the other side of the door jamb and activated by a keypad under a planter)

Also on the computer app, you can include mouse lockout and 30 seconds of unlockable screen saver for every wrong attempt, which is secretly logged. Most people who would try to break into your computer would do it while you're away for a minute and they won't have time...

You're right; they look like that anyway. That's what gave me the idea...

Actually, it's just the opposite. Most people that do try to break into your computer, do it when you are at the keyboard.

This might depend on several factors: do they have easy physical access to your computer? Does your computer have access to a network? Is said network publicly accessible? Is there easy physical access to the network?

If it's someone you know looking for gossip, or setting a prank physical access is more likely. If it's someone who stole or found your computer, physical access is also more likely. If someone just wants your banking data, they will probably try the remote method.

It really depends on who you leave your computer with, and who would want the data.

Although "away for a minute" seems like a horribly short period of time if the computer is not already running without password protection but that can hardly be called "breaking in"...

I was mainly thinking the sort of things that the Windows password login (when the screensaver shuts off) is there to prevent -- minor pranking, etc.

The unexpected QR code, with no clue how to get past it, would confuse them enough to usually stop the attempt... which would IMHO be a better deterrent than "here, guess my password."
Going back to the home security analogy, if someone wants in your house bad enough, they're getting in. The only thing you can do is make it not worth their time.

This is a modern analog for the classic PC joke: "Keyboard not recognized. Hit F1 to retry."

Unfortunately, it's not a joke. I've actually run into it less than a month ago on one of our servers.

I used to laugh at it, but these days I understand it as "You can't continue without a keyboard and I can't detect any. Fix it and prove to me you did".

Actually, it's just bad programming...
In the early startup stages (before loading the OS), you had a choice of having the computer stop on certain errors, or have it just continue and not mention them.
If you choose to have it report the errors to you on screen, it pauses, tells you the error(s) and gives you the prompt "Press F1 to continue"
Unfortunately, one of the errors it detects in this manner is "keyboard not found"

Resulting in "Keyboard not found. Press F1 to continue."

In the old days, that meant power down, fix the problem, power back up and see if you fixed it.
Because you couldn't tell it to ignore the fact there was no keyboard without a keyboard.

Somehow this reminds me of Threema (http://threema.ch/en/, it's like an encrypted WhatsApp): If you want to verify your peer's crypto key, you have to scan a QR code generated on the key owner's device. Comes in not so handy when your peer is a few thousand miles away...

do you know of any other way you can be sure your peer is who he claims to be, than meeting face to face?

of course there has to be some trust somewhere, generally i'd be willing to believe him, or rather, the auhorities, when he shows me his passport or drivers license.

So if some chap comes up to you in the street claiming to be me, and shows you his passport, you'd believe him? (yes, I know I'm being difficult)

I was afraid this discussion would happen...
It's a matter of how paranoid you want (or need) to be: If the peer was a complete stranger, I couldn't even be 100% sure about his identity when meeting face-to-face and seeing his (potentially fake) passport. He might still be a man in the middle with a fake identity. In such cases, a web of trust is needed, but even this can't be 100% reliable.

Speaking for me personally , if he is someone I already know well, hearing his voice reading back the key fingerprint to me on the phone could already be sufficient to me.

A total strangers personal identity is not all that relevant anyway. You don't know whether to trust him whether his identity is fake or not, because you don't know whether the person associated with the identity is trustworthy to begin with. If it's your friend, and you know the person as Angela, it's not really relevant if the government calls her Pamela. Really, the whole official identity scheme is rather ridiculous... Even more so as many people seem to accept the actual holding of passport as a proof of official identity without actually verifying whether the holder matches the passport description (height and similar face mostly).
