When you try to buy a concert ticket, a tortuous word puzzle pops up.
When the time for you to buy a ticket disappears, you stare at these words and scratch your head.
Your first few attempts are complete failures and you want to know why it is so difficult to confirm your humanity on the Internet. Those mind-
The days of bending are over.
Google announced on Wednesday that it will launch "CAPTCHA without verification code" to get rid of the verification code-
Those complicated and distorted puzzles
You can know that you are not a robot with a single click.
Now, this person just clicks on the checkbox next to the "I'm not a bot" statement.
"With this new technology, Google says it can differentiate between humans and automation programs by the way users move their mouse before clicking.
But in some rare cases a single click may not be able to provide a confirmation and will pop up
The up window will ask the user to resolve the distorted text.
On mobile devices, the new reCAPTCHA works a little differently, as there is no movement before clicking the button on the touch screen.
The user is asked to select all images that correspond to the thread instead of checking a single box.
For example, a clue may be a photo of a cat, and the user will select the matching image in the image of the cat, dog and hamster.
Humble Bundle, a Snapchat, WordPress and video game sales site, has adopted the software.
Google said that in the past week, recapbundle has more than 60% traffic on reCAPTCHA, and more than 80% of traffic has only passed the check box.
Vinay Shet, product manager of Google's reCAPTCHA team, told Wired.
The new reCAPTCHA will save users time.
"This greatly simplifies the experience for most users," says Shet . ".
"They basically get a free pass.
You can solve the verification code without solving it.
But Google did not develop the software to make life easier for people.
Last year, artificial intelligence startup Vicarious announced that it has developed software that can solve any type of verification code with at least 90% accuracy.
Prior to this, spammers hired CAPTCHA's team of solvers in Russia and Southeast Asia.
They pay their sweatshops.
About 75 cents for each of the 1,000 verification codes solved. CAPTCHAs (
A fully Automated Public Turing test that distinguishes computers from humans)
It was developed in 2000 to protect the site from spam and abuse.
By confirming that the user is human, CAPTCHAs prevents the automatic robot from creating a fake email address to send you a spam message or take away all tickets to the concert.
Early CAPTCHAs had evenly distributed letters and numbers that computers could easily decipher.
As CAPTCHAs become more advanced, they use scrolling characters to make computer translation more difficult.
Louis von Ann, associate professor of computer science at Carnegie Mellon University, helped develop verification codes, realizing that they wasted people's time and brain power.
"People around the world have about 0. 2 billion people typing every day.
"Every time you type one of them, basically you're wasting about 10 seconds," he told NPR on 2008 . ".
"If you multiply this number by 0. 2 billion, you will find that the whole human race is wasting about 500,000 hours a day, entering these annoying twists and turns.
"So he came up with a way to kill two birds with a stone.
His software, reCAPTCHA, uses CAPTCHAs to digitize old books and newspapers.
The two words presented come directly from the scanned book.
The company was sold to Google in 2009.
But these programs are also built to decode.
Vicarious 'software is one of the first software that can separate and distinguish each letter.
Google has been re-adjusting its CAPTCHAs since 2013.
On Valentine's Day, the company tested its new software by showing users unlost words such as "love" and "flowers", and relied on "advanced risk analysis" to distinguish people from robots.
The new system measures the entire contact between a person and a verification code.
Before, during and after his interaction with it.
While Google's new reCAPTCHAs will inevitably save users time and headaches, it raises privacy concerns.
Google already has access to a lot of personal information, but now it can identify a person by simply moving.
However, Shet says Google can only track user movements through the reCAPTCHA widget instead of the entire web page.
