There was a CTF a while ago where someone beat Google Captcha by simply inputting the Audio captcha into Google speech recognition. It worked ~80% of the time.

I'm sure that this can't scale at least against Google. They can fingerprint their own files. Might be interesting to check with MS or IBM services as a backup.

I'm pretty sure it would scale for Google in terms of net profits ;)

Yes, the American focus of the internet is absolutely appalling. Assumptions of timezones - PST, CST and the others whatever they are. Northern hemisphere assumptions of seasons - fall, etc - in the southern hemisphere the seasons are the opposite and we don't use the word fall. Even Apple, known for its "sensitivity" to cultural matters has a big miss on this one.

Even worse is the continued lack of UTF-8 use yet offering services outside of the US. In fact even Apple had non ASCII character issues on their dev website not so long ago.

Many of the criticism of the article focuses upon people being able to figure out Captcha's even if the aren't American, but there are a few things to consider: * A lot of native English speakers are going to have at least some exposure to American culture. For example: they may recognize that taxi's are yellow from American television and movies. Not everyone is going to have that exposure. * It assumes that there i…

This ignores an important point that this is a game of elimination and contrasts. For example in that taxi captcha, there are 4 pictures of trees and 5 pictures of vehicles. 1 vehicle is not identifiable, 1 is an utility van in the distance, and the remaining 3 are yellow cars. These yellow cars have phone numbers on the sides and signs on the roof (where visible). My bet is that the 3 yellow cars are taxis. (And as…

Perhaps, but it is still problematic.

The most important one was mentioned earlier. It offers an implicit advantage to Americans. In the olden days we would call this American-centric. These days we would call it prejudiced. Claiming that it is prejudiced is valid since it is effectively asking different people different questions. To the American, it is asking them to identify taxis. To a non-American, it is asking them to solve a riddle.

To highlight that point: most of your criteria relied upon cultural factors. Those taxis have no resemblance to taxis in my part of the world. Taxis in my part of the world are private vehicles with a small magnetically mounted "taxi" sign on the roof. There is no consistency in colour, little consistency in type of vehicle, and they most certainly aren't covered with advertising. I also wouldn't be surprised if there are a handful of utility van used as taxis in my city, since taxi companies offer accessible services.

The game approach also implies some degree of understanding of captcha's. The approach you outlined assumed that the unidentifiable vehicle would not be treated as a valid answer and that more than one image would have to be selected, so you can look for patterns. Knowing the rules of the game may be fine if you are playing a game. It certainly isn't appropriate in the case of operating a business or offering a public service.

> Ours are under a yellow steel panel flush with the ground, so not something self-driving cars need to identify. Why not? I would suppose it's forbidden to park over these, so identifying them makes sense.

In the UK, the panels are in the pavement or grass, not in the road

For Americans, in the UK “pavement” means “sidewalk”, and not “any paved surface”.

I am in Montreal, Everyday I got to school during winters I had to subject my laptop to -20c for 45min before coming back to a warm indoor. It's not like we have any alternatives. It's true for our phones as well. OP's points still stands. I would add that if your product can't stand this constant hot-cold cycle, don't get in the Canadian market.

Are you carrying your naked laptop around outdoors in below zero temperatures? Maybe a bag that nestles against your body would be a better idea.

You obviously never lived in cold climates. Everything outside my winters clothes is at outside temperature (inside is often not terribly hot either..). I am not about to carry my laptop in my coat, which are usually a somewhat tight fit.

I understand the purpose of CAPTCHAs when used as a security measure, but recently it seems like there has been a huge proliferation of them in all sorts of random places and it’s becoming very annoying. Even Google has taken to occasionally popping up CAPTCHAs just so I can see search results!

> (“suspicious activity on your network” - I’m using a reputable, top-tier UK mobile provider) So are a _lot_ of other people, for all kinds of purposes, including nefarious purposes.

Well, exactly. And of course the IP addresses are dynamic. So it seems a bit silly to treat a whole network as suspicious because someone on it (amongst thousands or millions) is doing something suspicious...

I get the same thing on Wikipedia sometimes because someone, who at some point in the past had my randomly assigned IP address, once made some dodgy edits. (Solution: reboot router to get new IP address!)

I suppose if we had static IPv6 addresses (each account always gets assigned the same IP) then this would be less of an issue.

It's a CTF, so a scalable product was not the goal here.

Yes, I get it, but i need solutions and I'm considering in that regard.

Not if this decreases their captcha reputation.

As others pointed out, that was likely intentional. Apple designed this safety mechanism into the laptop, so they would not have to deal with such warranty claims. Also the temperature change is not a problem while the laptop is non-operating. The alternative therefore is to wait for 10-15 min before turning it on.

This is not entirely accurate. Electronic devices are fogging up just like my glasses everytime I come inside. This is known to trip the water sensitive stickers used to deny warranty, even if the problem is obviously unrelated. Those are triggered regardless of if the device is powered on or off. To me this is strong evidence that electronic devices are not tested properly for our climate.

I see a lot of captchas that I was missing now that I am using the temporary container plugin [1]

Also for sites that I don't know why they need captchas...
