Hi, this is Wayne again with a topic “Why CAPTCHAs Are Harder Now”.
One of the most irritating things about modern life – you know other than political polarization, stagnating wages and the feeling of somehow being socially isolated in a hyperconnected environment is how difficult these stupid little capture puzzles have gotten. But why is this happening a while ago? We did an episode on those super simple, i’m not a robot recaptchas and those aren’t that bad. You just click a box and that’s it. But now it seems like we’re having to solve these arcane picture puzzles sometimes multiple times simply to read a news article.
So what gives well part of it is that the evolution of captchas to become more annoying is part of an ongoing arms race between spam, malware and shopping bots on the one side and cloud and website operators trying to stop them on the other. Back in the day, bots were so dumb that just a slightly distorted word or two could send them packing. But of course it was quite easy for fleshy humans to understand what was on the screen.
But unsurprisingly, there’s been a lot of investment over the past couple decades into automated optical character, recognition or ocr, which helps digitize old books and other publications, so that they’re more easily searchable doing. This requires ais to discern text, even if it’s distorted in some way. So, over the years efforts were made to make them better. At this and, unsurprisingly, the text we put into those little captcha tests, helped the ais.
Do this many captchas use scans of distorted words from real books or newspapers and because we humans took so many of these tests, we trained ais to become very good at them, but unfortunately, ai algorithms can be used by bots. So we stopped using word-based captures and moved on to those little picture puzzles which i’ll complain about more after this message from our sponsor jackery jackery’s explorer 1500 portable power station has enough juice to keep all your devices powered and connected. It’S huge 1500 watt hour capacity and 1800 watt output rate allows up to seven devices plugged in simultaneously and it takes only four hours to recharge up from zero to eighty percent check with the explorer 1500 at the link below and get 10 off with the code. Linus tech tips for a while picture captures proved more effective than word captures, but guess what google who’s responsible for producing many of those picture puzzles uses human input on those to train their ais as well. If you’ve noticed how lots of these captures are photos of street signs, traffic lights and crosswalks, etc? It’S because google is taking all that data that you give it when solving these puzzles and using that information to help build ais for self-driving cars, as well as to improve the quality of results on google maps and again ai’s got really good at solving these puzzles. So the folks behind captcha have been making them progressively harder, much to the chagrin of you, the average internet user who’s just trying to bulk by toilet paper online instead of schlepping up to walmart. But is there an end in sight to this arms race? The way, those i’m not a robot boxes, work without forcing you to solve a puzzle is by tracking your in-browser behavior. How fast you type how you move your mouse around. Even the way you switch tabs to determine that you’re human, and not a bot that can input paragraphs of text in a matter of seconds or move a mouse to precisely a single pixel location on the screen. Some engineers believe what we’ll end up.
Having is a kind of souped-up version of this, it’s no secret that you’re constantly being tracked in some form or another, while you’re online, so future versions of captcha may not only track the way you type remove your mouse, but also keep tabs on you more thoroughly Through cookies and browser activity to determine whether or not you’re human, such a capture would basically always be running in the background on a browser level. So while it might help us beat the bots, there are obvious privacy concerns, in addition to the fact that bots might end up beating these tests at some point in the future as well. I just hope it doesn’t get to the point where all computers come with a usb connected dna sample collectors.
