reCAPTCHA is a free CAPTCHA service that helps to digitize books, newspapers and old time radio shows. Check out our paper in Science about it (or read more below).
A CAPTCHA is a program that can tell whether its user is a human or a computer. You’ve probably seen them — colorful images with distorted text at the bottom of Web registration forms. CAPTCHAs are used by many websites to prevent abuse from “bots,” or automated programs usually written to generate spam. No computer program can read distorted text as well as humans can, so bots cannot navigate sites protected by CAPTCHAs.
About 200 million CAPTCHAs are solved by humans around the world every day. In each case, roughly ten seconds of human time are being spent. Individually, that’s not a lot of time, but in aggregate these little puzzles consume more than 150,000 hours of work each day. What if we could make positive use of this human effort? reCAPTCHA does exactly that by channeling the effort spent solving CAPTCHAs online into “reading” books.
To archive human knowledge and to make information more accessible to the world, multiple projects are currently digitizing physical books that were written before the computer age. The book pages are being photographically scanned, and then transformed into text using “Optical Character Recognition” (OCR). The transformation into text is useful because scanning a book produces images, which are difficult to store on small devices, expensive to download, and cannot be searched. The problem is that OCR is not perfect.
reCAPTCHA has the highest security standards. Many other implementations of CAPTCHAs use undistorted text, or text with only minor distortions. These implementations are vulnerable to simple automated attacks. Others, such as MAPTCHA, consist of asking text-based arithmetic questions like “what is 1+1”. These can be trivially broken by an attacker.
To protect your site, reCAPTCHA uses two layers of security when generating images. It starts with images that can’t be read by computers, and then distorts them even more:
reCAPTCHA is a Web service. That means that all the images are generated and graded by our servers. In addition to the convenience that this provides (you don’t have to run costly image generation scripts on your own servers), this also provides an extra level of protection: our CAPTCHAs can be automatically updated whenever a security vulnerability is found. For example, if somebody writes a program that can read our distorted images, we can add more distortions in very little time, and without Web masters having to change anything on their side. This is significantly more secure (and convenient) than having to re-install a CAPTCHA every time a vulnerability is found.
IP Address Detection
Our service also includes IP address filtering and detection. If we determine that a given IP address is successfully solving too many CAPTCHAs in a certain period of time, the address is immediately flagged for review. In addition, by providing CAPTCHA services to many customers we obtain a global view of spamming attacks, allowing us to react quickly to security threats.
New Delhi, Dec 6: Telecom minister Kapil sibal asked The social websites like Google and Facebook, to ensure that uploading of derogatory material is stopped. This was the outcome as a controversy raged over monitoring offensive content on internet platforms.
Maintaining that the government does not want to interfere with the press, he said if the social networking sites are not willing to cooperate with the government on stopping incendiary material “then it is the duty of the government to think of steps that we need.” “This government does not believe in sensation and does not believe either directly or indirectly interefering in the freedom of the press. We have demonstrated that time and again,” he said.
Sibal cited an example of a religious place that turned out to be a pornographic site, and told them such content played with religious sentiments, the sources said.
A number of retweets and comments on Twitter came pouring in on the demand made by him saying “Kapil Sibal is an Idiot”.
Kafila.org has started a campaign asking people to write ‘Kapil Sibal’ is an idiot’ on their Facebook status message, to use the hashtag #IdiotKapilSibal on Twitter and write a blog post with titles censorship, Internet censorship in India, Kapil Sibal and It is so common to hear people going on and on and on about how somebody famous and/or powerful is a complete idiot for doing something. They don’t understand how someone can be so totally bone-headed.
If you find yourself ever thinking like this (and I think this happens to all of us once in a while), stop and consider this question:
If that guy is such an idiot, and you can clearly see his faults, how come you are poor and unknown and that person is rich and famous?
Take, for example, the case of Kapil Sibal asking Google, Facebook, and co. to actively screen and filter all content before it is uploaded on their sites. Yes, on the face of it, it does seem rather an idiotic thing to say. However, my dear reader, I am willing to bet that Kapil Sibal is much smarter than you and me combined. He is a lawyer, he was the Solicitor-General of India, he had cleared the IAS exam (which is ridiculously difficult), and he has beaten Kyuki Saas Bhi Kabhi Bahu Thiin an election. So the best you and I can say is that we don’t really understand why Kapil Sibal is making such statements. There could be any number of reasons that you’ll never know. Maybe this is a move designed to win over rural voters. Maybe this is just a public stunt to soften up Google, Facebook for a backroom deal later on at terms very favorable to the Congress party. Maybe this is a way to make sure that Google, Facebook are very co-operative and pliable when police (or other government bodies) approach them with requests for private data.
I am amazed how fast this technology is moving. lots of technology and product there most of people thought its impossible.
Lets explore some of recent innovations and fact.
1 – Gmail Motion : A new way to communicate
The mouse and keyboard were invented before the Internet even existed. Since then, countless technological advancements have allowed for much more efficient human computer interaction. Why then do we continue to use outdated technology? Introducing Gmail Motion — now you can control Gmail with your body.
Google’s quality team is looking for talented, motivated, opinionated technologists to help us predict what users are looking for. If you’re eager to improve the search experience for millions of people and have a proven track record of excellence, this is a project for you!

If you logged into Gmail over the last hour (or visited the Gmail homepage), you probably noticed that something looked a bit off: all the vowels are missing. We realize this makes things difficult for all of you who rely on Gmail — whether at home or at work — and we’re incredibly sorry. We take morphological issues like this extremely seriously, so we want to let you all know what happened and what we’re doing about it.
At 6:01 am Pacific Time, during routine maintenance at one of our datacenters, the frontend web servers in that particular datacenter started failing to render the letter ‘a’ for a subset of users. As error rates escalated, the strain spread to other datacenters. We worked quickly to avoid a cascading failure of the entire alphabet by implementing a stopgap solution that limited the damage to the letters ‘a,’ ‘e,’ ‘i,’ ‘o,’ and ‘u.’ As a result, we’re experiencing Gmail’s first temporary vowel outage. (We’re still investigating whether the letter ‘y’ is impacted and will post an update here shortly.)
Over the last hour we’ve received numerous reports of this issue via our help forums, from colleagues at Google, and via email you’ve sent us. Some of you have already found creative workarounds for communicating without vowels, like Aaron, who sent us this:
Having 80.8% of the alphabet available is significantly below the 99.9% full letter uptime reliability we strive for. Since identifying the root case of this issue, we’ve started bringing vowels back to Gmail, so you should see them back in your account within the next few hours if you don’t already. In the meantime, while you may still see this issue in Gmail’s web interface, both IMAP and POP access are functioning normally. We’ll post an update as soon as things are fully resolved and, again, we’re v3ry s0rry.
Update (7:30 am): We’ve determined that the letter ‘y’ is not impacted.
The next generation of Google storage arrives in May and we’re looking for testers.
