Strengthening CAPTCHA-based Web security
Simple, universally applicable strategies can help any captchaprotected system resist automated attacks and can improve the ability of administrators to detect attacks. The strategies discussed here cause an exponential increase in the difficulty faced by automated attackers, while only increasing the inconvenience for human users in an approximately linear manner. These strategies are characte...
متن کاملCAPTCHA Based Web Security: An Overview
Completely Automatic Public Turing test to tell Computers and Humans Apart (CAPTCHA) is a HIP (Human interactive Proof) system. CAPTCHAs are used to improve the security of Internet based applications in order to ensure that a web based application which is intended to be used by a human being is not maliciously used by Artificially Intelligent programs called bots.

متن کاملImage-based face detection CAPTCHA for improved security
In this paper, we propose a novel image-based completely automated public turing test to tell computers and humans apart (CAPTCHA) that relies on detecting human faces to provide an additional layer of security in web-based services. Face images were selected from the CMU face database and subjected to different types of distortions at different intensity levels to make the automatic face detec...
متن کاملImage-based CAPTCHA with JACI
This paper proposes JACI (Just Another CAPTCHA Implementation). JACI is an image-based CAPTCHA technology that requires users to match like images with their partner image in order to pass the test. JACI is not dependant on keyboard interaction which aids some forms of accessibility and does not require internationalisation. Interaction is controlled with a pointing device such as a mouse; as e...

The massive and automated access to Web resources through robots has made it essential for Web service providers to make some conclusion about whether the "user" is a human or a robot. A Human Interaction Proof (HIP) like Completely Automated Public Turing test to tell Computers and Humans Apart (CAPTCHA) offers a way to make such a distinction. CAPTCHA is a reverse Turing test used by Web serv...
