captcha

问题 In the new Magento release the captcha options in "System->Configurations->Customer Configuration->Captcha" I created a new form called "Signmeup"... but it does not seem to be working. I am having trouble getting it to show: <?php echo Mage::getSingleton('core/layout') ->createBlock('captcha/captcha_zend') ->setFormId('signmeup') ->setImgWidth(230) ->setImgHeight(50) ->setTemplate('captcha/zend.phtml') ->toHtml();?> Right now that block is not being displayed on the page. (Not a dynamic page

问题 A member of my company in greater ranking than myself refuses to use recaptcha.net on his website to thwart spam off of a public form. He thinks it would be difficult for anyone coming to our site to enter their information since the Turing Tests are "so darn hard to read". Is there an alternative to using this method? That doesn't contain these sorts of difficult to read images? (Okay stupid question...if it were up to me we'd use recaptcha because everyone else on earth does...but I just

问题 Firstly, I'd like to say that I do not want to use any libraries that are not provided with Python 2.7.10. The same question was posted on Stack Overflow but was answered with the Requests library. I have a script that logs into Roblox.com using urllib2. To check if there is a captcha before I try to log in, I wanted to do check_captcha = re.findall('recaptcha_image', newlogin) but roblox needs to redirect to the captcha login page AND the captcha has to load onto the page. So how can I make

问题 My web site has a database lookup; filling out a CAPTCHA gives you 5 minutes of lookup time. There is also some custom code to detect any automated scripts. I do this as I don't want someone data mining my site. The problem is that Google does not see the lookup results when it crawls my site. If someone is searching for a string that is present in the result of a lookup, I would like them to find this page by Googling it. The obvious solution to me is to use the PHP variable $_SERVER['HTTP

问题 I have the following piece of code inside an h:form <h:panelGrid id="captchaGrid"> <p:captcha id="captcha" label="Captcha" required="true" requiredMessage="required" validatorMessage="..."> </p:captcha> <p:message id="captchaMessage" for="captcha" /> </h:panelGrid> <p:commandButton id="submitButton" value="save" actionListener="#{userBean.save}" update="captchaGrid" onstart="doSomething()" oncomplete="doSomethingElse(xhr, status, args)" icon="ui-icon-check"> </p:commandButton> This works fine

问题 I'm looking for inspiration here. I need to employ some sort of human verification for my website, but the most common method these days (asking users to type the letters & numbers they see in an image into a text input box) seems a little rubbish - I find it hard sometimes to work out what the letters & numbers are. There must be a better way! I've had a few ideas, the best one seems to be to show users a series of images (4-6), and ask them to answer a question based on the contents of the

问题 I want to limit the failed login attempts. For example, if a specific user attempt to login with wrong username or password 4 times, i should show the CAPTCHA 4th time instead of blocking for some specific time, and keep showing CAPTCHA unless he supplies valid username and password. Once the user has successfully logged in, the login attempt is reset to ZERO. Is the idea of checking the username instead of IP address OK in security point of view? Can this approach be implemented without

问题 What is the best unobtrusive CAPTCHA for web forms? One that does not involve a UI, rather a non-UI Turing test. I have seen a simple example of a non UI CAPTCHA like the Nobot control from Microsoft. I am looking for a CAPTCHA that does not ask the user any question in any form. No riddles, no what's in this image. 回答1: I think you might be alluding to an "invisible" captcha. Check out the Subkismet project for an invisible captcha implementation. http://www.codeplex.com/subkismet 回答2: Try

问题 I googled for integration of Captcha in iOS app but do not found any relevant way to do so. Even i sign up with reCAPTCHA and searched whether the plugins for Captcha are available for iOS or not? I didn't found any plugin for iOS there.
