Figure 9 5. A simple cognitive captcha Yet another variant on the cognitive captcha is to ask a simple question and then expect a correct response. For example, asking what is the color of snow (correct answer: white) or what is 4 + three (correct answer: 7) can be an excellent way of cutting down on bot responses. Such captchas are designed to ratchet up the demands of meeting the challenge, in an attempt to discriminate more precisely between human and mechanical responders. This they are indeed likely to do, but at the expense of excluding legitimate human responders who are not up to the considerable cognitive demands involved. Furthermore, such challenges are difficult to construct and validate, and so it is incredibly time-consuming to generate a pool of sufficient size to be usable on a large scale. Given a small universe of such challenges, and the dichotomous nature of many of the questions, high-volume guessing becomes a powerful strategy for successful answering. To our knowledge, the Bongo is still a theoretical possibility that is not in actual use, no doubt for exactly these reasons. In conclusion, then, captchas are a challenge that may not work very well in high-stakes settings, where the rewards of successfully answering them warrant an attacker s expending the effort to do so. But they can work very well in a relatively low-stakes setting, where they can be generated easily, where they resist simple attacks, and where they exclude few legitimate users. And so you as a programmer should understand how to use them.

Note To use the XDocument class and LINQ to XML, you must add a reference in your Silverlight project

-- Send a message to the AccountingService SET @msgAccountingService = '<AccountingRequest> <CustomerID>' + @customerID + '</CustomerID> <Amount>' + CAST(@amount AS NVARCHAR(10)) + '</Amount> <AccountingRequest>'; SEND ON CONVERSATION @chAccountingService MESSAGE TYPE [http://ssb.csharp.at/SSB_Book/c06/AccountingRequestMessage) (@msgAccountingService); -- Begin a new conversation with the InventoryService on the same -- conversation group BEGIN DIALOG CONVERSATION @chInventoryService FROM SERVICE [OrderService] TO SERVICE 'InventoryService' ON CONTRACT [http://ssb.csharp.at/SSB_Book/c06/InventoryContract] WITH RELATED_CONVERSATION = @ch, ENCRYPTION = OFF; -- Send a message to the InventoryService SET @msgInventoryService = '<InventoryRequest> <ProductID> + CAST(@productID AS NVARCHAR(10)) + '</ProductID> <Quantity' + CAST(@quantity AS NVARCHAR(10)) + '</Quantity> </InventoryRequest>'; SEND ON CONVERSATION @chInventoryService MESSAGE TYPE [http://ssb.csharp.at/SSB_Book/c06/InventoryRequestMessage) (@msgInventoryService); END Let s have a more detailed look at the different parts of the message-processing logic for the OrderRequestMessage message type. In the first step, you declare some variables to store the conversation handles for the new started conversations and the messages that are sent over the new conversations: -- Variables needed to store the information extracted -- from the OrderRequestMessage DECLARE @creditCardHolder NVARCHAR(256); DECLARE @creditCardNumber NVARCHAR(256); DECLARE @validThrough NVARCHAR(10); DECLARE @quantity INT; DECLARE @price DECIMAL(18, 2); DECLARE @amount DECIMAL(18, 2); DECLARE @customerID NVARCHAR(256); DECLARE @productID INT;

Given the complexity and difficulty of using advanced captcha techniques, we confine ourselves to using the simplest kind of visual captcha, which presents a nondistorted (or minimally distorted) image of a word to a user, who must enter that word into a form. Such a challenge is capable of being used effectively in the vast majority of situations, and is unlikely to exclude many legitimate users.

Every XDocument holds a collection of XNode objects. The XNode is a MustInherit base class. Other more specific classes, like XElement, XComment, and XText, derive from it, and are used to represent elements, comments, and text content. Attributes are an exception they are not treated as separate nodes, but simple name-value pairs that are attached to an element. Once you have a live XDocument with your content, you can dig into the tree of nodes using a few key properties and methods of the XElement class. Table 17-2 lists the most useful methods. Table 17-2. Essential Methods of the XElement Class

The new XML data type of SQL Server 2005 offers several methods you can use to query and update the stored XML data directly inside the database. These methods are query(), value(), exist(), nodes(), and modify(). With the query() method, you can directly execute an XPath or XQuery statement that returns an XML fragment back to you. When you want to get a scalar value out of the XML data, you can use the value() method on the XML data type. If you want to check if a specified node is available in the XML, you can use the exist() method. Finally, you can use the nodes() method to shred XML into multiple rows to propagate parts of the XML data into rowsets.

There can be no question that the simplest way to use a captcha is to let someone else do all the work We are now seeing commercial web services that, for a fee, will allow you to incorporate a captcha challenge based on their servers into your website In this case, all the effort of presenting the captcha and evaluating the user s answer takes place off your site and outside your knowledge Recently we have also begun seeing open source or otherwise free sources for the same kind of service Such services allow you to screen users with no more effort than putting a few lines of prefabricated code into your own scripts To use the captchasnet service (at http://captchasnet/), for instance, you first request a username and secret key from the site (free for noncommercial use).
