It’s Time to Dive into the Story Of Captcha -spam Fighter.
In the beginning of internet era SPAM Fighting effort Started Like this.
To submit the form the math Operation needs to be Solved. the developer thoughts it could stop BOTS. but it definitely NOT.
in 2003 group of Carnegie Mellon University students Invented the First CAPTCHA System which Looks Like this.
A CAPTCHA will have a text box down the bottom, where you are required to write the words down.
For example, here, one would write ‘JR448’
At this time Captcha used by the Internet Crossed more than More than a million per day, Here comes the challenge more CAPTCHA Databases needed.so scanned all the Books Available and Digitized them used OCR Softwares to recognize text. Separated The Texts which are hard to identify by OCR software added them to CAPTCHA Databases.
As Google Says,
CAPTCHA digitizes books by turning words that cannot be read by computers into CAPTCHAs for people to solve. Word by word, a book is digitized and preserved online for people to find and read.
CAPTCHA Solving Per Day raised to 100 Million Per day This Time Google Helped them with their Google maps Database. they identified the Street Numbers Not recognizable by OCR Software and fed them to CAPTCHA Databases.
The Numbers Skyrocketed, now they ADD audio Support to The Captcha mechanism. Developers feel This will Help them to solve SPAM Problems. But Definitely Not.
Here Comes the new problem, CAPTCHA Solvers
You read it correctly, they Charge around 0.7$ for 1000 Captchas.
Google’s Next Step Towards SPAM Fighting
Meanwhile, At Google Found, only 33% of humans Solved the CAPTCHA correctly but BOTS Solved it by 99.8%.
At this time google is introducing Semantic Approach to its SERP Pages Using Hummingbird Algorithm.
