The goal of the Web Services Activity is to develop a set of technologies in order to lead Web services to their full potential. The Web Services Activity Statement explains the W3C's work on this topic in more detail. The World Wide Web is more and more used for application to application communication. The programmatic interfaces made available are referred to as Web services.

Web services provide a standard means of interoperating between different software applications, running on a variety of platforms and/or frameworks. Web services are characterized by their great interoperability and extensibility, as well as their machine-processable descriptions thanks to the use of XML. They can be combined in a loosely coupled way in order to achieve complex operations. Programs providing simple services can interact with each other in order to deliver sophisticated added-value services.

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.

Use reCAPTCHA on Your Site! reCAPTCHA helps prevent automated abuse of your site (such as comment spam or bogus registrations) by using a CAPTCHA to ensure that only humans perform certain actions.

Free CAPTCHA-Service provides CAPTCHA images and audio files you can use in html-forms. CAPTCHA images can prevent forms to be used by robots. How does it work? A CAPTCHA image shows a random string which the user has to type to submit a form. This is a simple problem for (seeing) humans, but a very hard problem for computers which have to use character recognition, especially, because the displayed string is alienated in a way, which makes it very hard for a computer to decode.

E-Mail Address Protection encrypts your e-mail address in a way, that makes it impossible for automatic programs (so called "address harvesters"), to find your clear-text e-mail address on web pages, and to consequently use it for sending you unwanted commercial e-mails (so called SPAM).
