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.現在，這些日子，只是每個大型網站有一個captcha綱領，瘋狂和豐富多彩的扭曲文本的圖像出現在底層的註冊頁面或簽名表格。 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.這些captcha的，是用來防止"機器人" ，從能夠簽署了自動，因為它仍然是不可能的電腦程式，以便能夠閱讀歪曲文本，但很容易為人類大腦這樣做。
reCAPTCHA recaptcha is a service where you can get CAPTCHA’s for your site that helps to digitize books.是一項服務，你能得到captcha的為你的站點，可以幫助數字化圖書。 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.據到現場，有6000多萬，這些captcha的是解決了以往一天，導致約15萬小時的實際工作正在做。 Their purpose is to use that time to help digitize books by having people help ”read” online.其目的是要利用這段時間，以幫助數字化圖書，由人民幫助"改為"線上。
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.因為數以百萬計的書籍，成為數字化，在未來數年（由Google等） ，他們是被掃描到計算機圖像，然後再轉換為文本利用光學字符識別技術。 The images must be converted to text so that the books can easily be searched and stored using less space than images.圖像必須轉換為文本，使本書可以很容易被搜查，並儲存使用空間比圖像。 The issue with OCR, however, is that it’s not super accurate a lot of the time!這個問題的OCR ，但問題在於，它不是超級準確了大量的時間！ That’s where reCAPTCHA comes in.這也就是recaptcha責無旁貸
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.他們發送的話，不能閱讀由電腦出了Web的形式captcha的，讓人類破譯。 Basically, each and every word not read by the computer is made into an image and use as a CAPTCHA.基本上，每一個字沒有看過由電腦製成影像，而且利用作為一個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，這一項目所產生的兩個captcha的，一人，它知道答案和其他它不能閱讀。 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.當人類deciphers都和電腦看到這個人正確回答了一個，它已經知道的，它假設的答案，另一條是正確的也是。 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.然後持這新詞，它剛剛得到的答案，並造成另一隊為別人閱讀，以確保原來的那個字是正確的。
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.有兩種方法，你可以用一個captcha從recaptcha對你的站點：如果你運行一個網站，或者如果你想阻止垃圾郵件。 If you’re running a blog on WordPress or Mediawiki, they have plugins that you can install without having to write any code.如果您正在運行博客上的WordPress或mediawiki ，他們有插件，你可以安裝不必寫任何代碼。 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有關濫發電郵的選擇是相當漂亮的，因為它讓你後你的電子郵件地址，網站發動進攻，但在很短的形式，如 Ase…@yahoo.com ASE的… @ yahoo.com and in order to reveal the full address, a user has to click on the … and solve a CAPTCHA.並且為了揭示詳細地址，用戶按一下就… …和解決一個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.這項服務完全免費，有利於數字化圖書，易於安裝（插件或幾行的HTML ） ，甚至有一個音頻測試方法，可用於人雙目失明。 Check it out and use it to help a good cause!了解一下它，並用它來幫助一個好的事業！
