Preventing massive automated access to Web resources      

Automated web tools are used to achieve a wide range of different tasks, some of which are legal activities, whilst others are considered attacks to the security and data integrity of online services. For this reason, effective solutions to counter the threat represented by such programs are required.
We have studied the problem of massive automated access to web resources and we have developed MosaHIP, a Mosaic-based Human Interactive Proof (HIP, also known as CAPTCHA). Properties of the proposed solution grant an improved security over usual text-based and picture-based HIPs, whereas the user-friendliness of the system alleviates the user from the discomfort of typing any text before accessing to a web content.
