Internet telephony is of interest not only to communications companies and users but also to those who want to infect it with lucrative spam. In the case of VoIP, the phenomenon is called… SPIT (SPI've been over Internet Telephony): Instead of spam mail with text and images, bot gets massaged phones, causing unmistakably more discomfort than an unsolicited message in our online mailbox. The threat consists of the massive automated sending of incoming calls, messages, and presence requests.
Efforts to deal with it continue as it is clear that existing antispam techniques are not enough. One of the suggested approaches to cut unsolicited internet calls is voice CAPTCHA, utilizing the tone of speech, random mid-sounds and their dispersion within the message, so to distinguish the man from the bot, with encouraging results so far, the researchers say. Cutting edge technologies are also considered Formal Model Checking and Privacy Enhancing Technologies (PET) techniques.
A group of actors in Greece are collaborating on the project "SPHINX" to develop a service that prevents automated spam attacks through VoIP, which will be integrated into existing corporate services. The project is funded by the General Secretariat for Research and Technology in the framework of the Operational Program Competitiveness and Entrepreneurship, Action of National Interest COOPERATION.
The SFIG Consortium consists of Virtual Trip scientists from the Aristotle University of Thessaloniki, the Democritus University of Thrace and the Athens University of Economics and Business in an effort to create robust online services with the distinction of man or machine with interactive sound instruments.
- For the SFIG project, their representatives will speak in detail Wednesday, 19 December 2012 in a multidrug that is organized between 17.00 and 21.00At Amphitheater of Antoniados Wing at the Athens University of Economics and Business.
