I own four computers. Two desktops. One laptop. One Microsoft notebook. Three have Win 11. One has 10. Lately, on a desktop w/11, frequently, when I'm searching google for data, when I type in the phrase or business or topic, I'll get a captcha test. It's becoming more frequent. I always clear my cache, run ccleaner, clear history, etc. It's still happening. And none of my other computers are doing it. When it happens, it starts with the "I'm not a robot" box which I check. Directly underneath it has some computer lingo with the word "google" in it. And...

Completely Automated Public Turing test to tell Computers and Humans Apart – better known as the ubiquitous CAPTCHA we see standing athwart the doors to many websites – may now be a misnomer as researchers have found that computers are much better at completing them. The bot defense measure dates back to 1997 and the tortured acronym 2003, with the technology starting out as a distorted series of letters and/or numbers. Google's implementation, reCAPTCHA, eventually did away with much of these shenanigans to make the browser identify low-risk human users in the background, but the image verification method still pops...

A joint academic research project from the United States has developed a method to foil CAPTCHA* tests, reportedly outperforming similar state-of-the-art machine learning solutions by using Generative Adversarial Networks (GANs) to decode the visually complex challenges. Testing the new system against the best current frameworks, the researchers found that their method achieves more than 94.4% success on a carefully curated real-world benchmark dataset, and has proved capable of ‘eliminating human involvement’ when navigating a highly CAPTCHA-protected emerging Dark Net Marketplace, automatically resolving CAPTCHA challenges in a maximum of three attempts.

CAPTCHA, which stands for “Completely Automated Public Turing tests to tell Computers and Humans Apart,” first appeared in 1997 and has proliferated across the Internet, slowly morphing into the “Find the bicycle” challenges that we face today. Cloudflare, who obviously has money riding on anything that makes it easier to sift robot attackers from humans, is proposing a new service that uses hardware keys to confirm your existence. The most popular model, the Yubikey, is a little dongle that connects to your computer and sends a special code when you touch a conductive surface. In this case, the USB key...

If there is one thing I hate, it is spam. I hate spam email, spam snail mail, and most of all, spam comments on my blog. I take great pains to keep spam comments off Political Realities. At the same time, I want to make it easy for normal commenters to leave their thoughts on the blog, even if I disagree with what they have to say. That said, this post may only be of interest to those of you who operate WordPress blogs, but it is important enough for me to share in a post of its own. Every...

The combination of simple codes and Captchas, which are even more encrypted using a chaotic process, produces effective password protectionApril 19, 2011 The passwords of the future could become more secure and, at the same time, simpler to use. Researchers at the Max Planck Institute for the Physics of Complex Systems in Dresden have been inspired by the physics of critical phenomena in their attempts to significantly improve password protection. The researchers split a password into two sections. With the first, easy to memorize section they encrypt a Captcha – an image that computer programs per se have difficulty in...

Don’t you just love Captchas? CAPTCHA is an acronym for “Completely Automated Public Turing Test.” Completely Automated Public Turing test to tell Computers and Humans Apart.” I just call them PITA (pain in the ass). Here are my top 10 worst Captcha’s ever. From best to worst:
