Now these days, just about every large web site has a CAPTCHA program, crazy and colorful distorted text images that appear at the bottom of registration pages or signup forms.现在，这些日子，只是每个大型网站有一个captcha纲领，疯狂和丰富多彩的扭曲文本的图像出现在底层的登记页或注册表格。 These CAPTCHA’s are used to prevent “bots” from being able to sign up automatically since it is still impossible for computer programs to be able to read distorted text, but quite easy for the human brain to do so.这些captcha的，是用来防止"机器人" ，从能够签署了自动，因为它仍然是不可能的电脑程式，以便能够阅读歪曲文本，但很容易为人类大脑这样做。
reCAPTCHA recaptcha is a service where you can get CAPTCHA’s for your site that helps to digitize books.是一个服务你能得到captcha的为你的网站帮助，以数字化图书。 According to the site, there are over 60 million of these CAPTCHA’s that are solved ever day, resulting in about 150,000 hours of actual work being done.据到现场，有6000多万，这些captcha的说，解决了以往一天，导致约15万小时的实际工作正在做。 Their purpose is to use that time to help digitize books by having people help ”read” online.其目的是要利用这段时间，以帮助数字化图书，由人民帮助"改为"线上。
As millions of books become digitized in the next few years (by Google, etc), they are being scanned into computers as images and then converted to text using OCR technology.因为数以百万计的书籍，成为数字化，在未来数年（谷歌等） ，它们会被扫描到计算机作为图像，然后再转换为文本利用光学字符识别技术。 The images must be converted to text so that the books can easily be searched and stored using less space than images.该图像必须转换成文本，使本书可以很容易被搜查，并用储存，节省空间的图像。 The issue with OCR, however, is that it’s not super accurate a lot of the time!这个问题， ocr的，但问题在于，它不是超级准确了很多时间！ That’s where reCAPTCHA comes in.这是那里recaptcha的地方。
They send the words that cannot be read by the computers out to the Web in the form of CAPTCHA’s and let the humans decipher them.他们发送的话是不能阅读的电脑出了web的形式captcha的，让人类破译。 Basically, each and every word not read by the computer is made into an image and use as a CAPTCHA.基本上，每一个字没有看过由计算机制成图像，并利用作为一个captcha 。 The way it works is that the program generates two CAPTCHA’s, one for which it knows the answer and the other that it cannot read.其工作方式是，这一项目所产生的两个captcha的，一人，其中知道答案和其他它不能阅读。 When the human deciphers both and the computer see that the human correctly answered the one it already knew, it assumes that the answer to the other one is correct also.当人类deciphers都和电脑看到这个人，正确回答了其中一个，它已经知道的，它假设的答案，另一条是正确的也是。 It then takes that new word that it just got the answer for and creates another pair for someone else to read to make sure the original word was correct.其次，新词，它只是得到答案，并造成另一队为别人阅读，以确保原来的那个字是正确的。
There are two ways that you can use a CAPTCHA from reCAPTCHA on your site: if you run a web site or if you want to block email spam.有两种途径，你可以使用一captcha从recaptcha对你的站点：如果你运行的网站或者如果你想阻止通过电子邮件发送垃圾邮件。 If you’re running a blog on WordPress or Mediawiki, they have plugins that you can install without having to write any code.如果你运行博客对wordpress的或活动中，他们有插件，你可以安装不必写任何代码。 The email spam option is pretty nifty because it allow you to post your email address on a site, but in a short form, such as有关滥发电邮的选择是相当漂亮，因为它让你后你的邮件地址，网站发动进攻，但在很短的形式，如 Ase…@yahoo.com酶… @ yahoo.com and in order to reveal the full address, a user has to click on the … and solve a CAPTCHA.并且为了揭示详细地址，用户必须点击就…和解决captcha 。
The service is completely free, helps digitize books, easy to install (plugin or a few lines of HTML), and even has an audio test that can be used for people who are blind.这项服务完全免费，有利于数字化图书，便于安装（插件或数行的html ） ，甚至有一个音频测试，可用于人双目失明。 Check it out and use it to help a good cause!了解一下它，并用它来帮助一个好的事业！
