Why Captcha has turned into checkboxes??


A CAPTCHA is a type of challenge–response test used in computing to determine whether or not the user is human. The term was coined in 2003 by Luis von Ahn, Manuel Blum, Nicholas J. Hopper, and John Langford. The most common type of CAPTCHA was first invented in 1997 by two groups working in parallel

 But google bots are 96% accurate in decoding these Captchas

 So google introduced a new alternate to captcha. i.e,,Re-Captcha

 In 2017, Google improved this mechanism, calling it an "invisible reCAPTCHA". According to former Google "click fraud czar" Shuman Ghosemajumder, this capability "creates a new sort of challenge that very advanced bots can still get around, but introduces a lot less friction to the legitimate human.

 That is the check box you find in some sites..!!

what is photodna?

Image
PhotoDNA  is a technology developed by  Microsoft  and improved by  Hany Farid  of  Dartmouth College  that computes  hash  values of images, video and audio files to identify similar images. [1]  PhotoDNA is primarily used in the prevention of child pornography, and works by computing a unique hash that represents the image. This hash is computed such that it is resistant to alterations in the image, including resizing and minor color alterations. [1]  It works by converting the image to black and white, resizing it, breaking it into a grid, and looking at intensity gradients or edges. [2] It is used with Microsoft's own services  Bing  and  OneDrive , [3]  as well as by  Google Gmail ,  Twitter , [4]   Facebook , [5]   Adobe Systems [6]  and the  National Center for Missing & Exploited Children , [7]  to whom Microsoft donated the technology. Microsoft donated the ...

DWARF PLANET, NAMED GOBLIN, FOUND WELL BEYOND PLUTO

Image
A scrawny dwarf planet nicknamed the Goblin   has been discovered well beyond Pluto .   A round frozen world just 186 miles (300   kilometers) across, the Goblin was spotted by   astronomers in 2015 around Halloween, thus   its spooky name. But it wasn’t publicly unveiled   until Tuesday following further observations   with ground telescopes. Scott Sheppard of the Carnegie Institution for   Science , one of the astronomers who made the   discovery, said the Goblin is on the small end   for a dwarf planet. It is officially known as 2015   TG387 by the International Astronomical Union’s   Minor Planet Center.   This is the third dwarf planet   recently found   to be orbiting on the frigid fringes of   our   solar system . Goblin’s orbit is extremely elongated — so   stretched out, in fact, that it takes 40,000 years   for it to circle the sun .   At its most distant, t...

HYDROGEN OR BATTERIES? Which is best?

Image
Hydrogen  Vs  Batteries Hydrogen cars   have long ranges RANGE: 700+ km. REFUELING : In a few minutes. CHALLENGE: Few filling stations and expensive production method. ADVANTAGE: Hydrogen can store energy from renewable sources such as solar cells and wind turbines. Battery-powered cars get   their energy from the grid RANGE: A maximum of 500 km. RECHARGING: 1-12 hours. CHALLENGE: Short range and very long charging time. ADVANTAGE: Communicate with the future grid, so the power can be as cheap as possible. Hydrogen stores energy well   The major sales argument for hydrogen is its   ability to store energy. Hydrogen contains 120   mega joules  of energy per kg – compared to 44   for petrol. At best, batteries can store 2-3   mega joules  per kg. a   fully   fueled hydrogen   car has a range of 6-700 km, which is about the   same ...
