An entire wall of lava lamps

Ikr it’s very reassuring

Java lamps: randomness found on an island in the Far East Fava lamps: randomness due to beans made famous by the film The Silence of The Lambs Cava lamps: randomness due to Spanish wine Lava lamps: randomness found by analysing the glow of a volcano Lava Lamb: a model of a farmyard animal carved from solidified lava Cassava lamps: randomness from root vegetables

Tom Scott pro hacker

No. You couldn't. You could predict the lava lamp's state, yes... But the exact amount of dust, the placement of the lamps, the amount of dust in the room, whether or not a car drove by, the exact angle of the camera and the quality of the camera (i.e how often does it take a photo, how high is the resolution, what colour space is it mapping it to), all contribute to the number

leave a camera in there

_"Chris urquhart"_ You clearly don't understand chaos theory. Even if you had the EXACT lava lamp, and put the EXACT same bubble pattern in it, minute differences (your exact voltage heating the lamp, error in exactly approximating the lava lamp, a 0.001C difference in room temperature) would propogate and quickly have your "copy" diverge from what it is modeling. It's a CHAOTIC SYSTEM. What you are proposing is aakin to forecasting the weather, a decade in advance, from today's known data. There's NO POSSIBLE WAY you could know the data precisely enough to do that...you could be pretty damn accurate for a week, then chaos would rear it's ugly head. (You forgot to account for that one butterfly in Madagascar that flapped its wings.)

The sad thing is people think they are safe using ssl when they are not. Browsers always have " security.ssl.require_safe_negotiation" off. For mozilla firefox, in the address bar type about:config then enter. Then type ssl into the search box. Then look for security.ssl.require_safe_negotiation . Change it from false to true. *just a warning. websites with bad security won't work anymore* . And Some ads may disappear. Some insecure ssl advertisements were used by foreign governments to hack everyone's internet browsers. I don't know if they still are

wait sorry i didn't read the replies before i said that

If the singapore office is recording radioactive material, they're already using the mechanism behind the Schrödinger's cat thought experiment without the needless felicide

Latooni Subota But you know, cats are bigger than splitting atoms. There are so many different cat species out there that a cat popping into existing still very random as you don’t know how big it was and it fur color. An atom is a little more predictable. But I agree, if cats (although internet’s favorite, still manages to be difficult to manage), radioactivity is a close and good second option.

They should just use videos uploaded to KZfaq in order--that ought to be sufficiently random for anyone, I should think! :)

d2factotum except for the fact, that you could hack youtube and filter the types of video you need to create the code for you. Nobody should know, that youtube is the source for the randomness in that case.

12am

I don't think that would be recommended mainly because the photos could be accessed by hackers and used to generate the same random keys. This is probably on a closed network making it very difficult to hack.

Anyone who cares enough about randomness to consider a solution like that are probably too paranoid to outsource it.

The pieces are inexpensive enough that any company that needs such setup probably already has one. Using a lava lamp to generate and re-generate your own passwords and keys is probably smarter.

Yes they could, but, here they do it for free, so it's not gonna work.

No, because the duplication would compromise the "randomness". Think about it. You're pointing your camera at the lava lamps, running an algorithm to get a random number - e.g. 4589237598236529870 - and then you send out that exact same number to 100 companies. They're all getting the exact same number. So let's say that you're getting this feed of random numbers and so am I. We both get the number 4589237598236529870 sent to us. You use it to create an encryption key. All I have to do is use the exact same algorithms as you and the encryption key I get will be exactly the same. Thus, I can break your encryption. You can't duplicate random numbers and hand out the same numbers to different people, because that makes them perfectly predictable. Whatever number you were given is exactly the same number I was given too. Thus, if you were doing this, then you could only sell your random numbers to a single company. Either that, or you couldn't send out the same number twice. But that has its own problems, in that you have to obtain a random number, send it out, obtain a new random number, send it out, and so forth. You'd be limited in the amount of companies and / or the rate at which you could send out numbers, simply because of the time it takes to "round robin" through all your customers to hand them each a unique random number. (To explain, imagine that it takes 0.1 seconds to take a picture, process it and produce a random number. You have 10,000 customers. So to "round robin" through all your customers, giving them each a unique random number would take 10,000 x 0.1 seconds = 1,000 seconds or 16.667 minutes. So one particular customer only gets 1 random number from you every 17-ish minutes. If they need a lot of random numbers for cryptography, then that rate would just be much too slow for them.) No, if you're serious about your random numbers for cryptographic purposes, you can't source them from the same place as anyone else. You need your own source of randomness. Like, ooh, a big wall of lava lamps, say. Sure, choosing to use lava lamps, that's "theatre" to generate publicity. But the fact that they own their own source of randomness like this to ensure that it's totally unique and can't be duplicated, that's perfectly sound and logical security.

Funny how they claim that without an unbiased third party checking its legitimacy.

SpinDreams exactly my thought

Then somehow determine the algorithm used to translate physical images into hashes, after determining the data that they transcribe them.

Well sort of, they probably have multiple cameras looking at the lava lamps in different directions generating even more encryption hashes seems pretty hard to do anything with just their vid feed, you would also need their exact software to generate the "random keys"

If your camera feed was timed wrong (due to network lag, different computer, etc.) by even a a fraction of a second you may not get the same random numbers. A very small variation in speed or very small deviation from their process for generating numbers from that many continuously moving lava lamps generating that long of a number would lead to failure because a 99% correct key would be useless.

ya know there are things that you can't just "hack into" right?

It would be, but these days, wouldn't have enough bitrate.
