Google has finally acquired reCAPTCHA, which is a company that provides CAPTCHAs to help protect more than 100,000 websites from spam and fraud.
CAPTCHAs are services used by websites to prevent malicious programs from scalping tickets or to get millions of email accounts for spamming. But the downside is that the words that are used in CAPTCHAs come from old books and scanned archival newspapers . Thus, these words are hard to recognize for the computers. Today, lots of websites are using CAPTCHAs including Facebook and craigslist .
It is said the acquisition of reCAPTCHA is very useful for Google in many ways:
- First of all, they get cooler CAPTCHAs than the random strings of letters that they have been in the past on their Blogger and other services.
- Secondly, they get free help decipher unintelligible words in their Google Books, Google News Archiveand some other related to scanning.
