Is your message inbox clogged with spam messages everyday? Do you  want to get rid of those useless junk SMSs then help is at hand.  Ponnurangam Kumaraguru, assistant professor at the Indian Institute of  Information Technology (IIIT) Delhi has developed what he calls  SMSAssassin, software designed to filter spam messages. Currently the  software is designed to run on Nokia’s Symbian system but very soon the  research team will be developing a version for other popular operating  systems such as Google’s Android and Windows Mobile.    
Sending SMSs has become a popular and relatively cheaper option to  advertise one’s goods and services and large number of companies is  using this publicity gimmick to advertise giving a headache to the  mobile user. Many steps have been taken in recent past by the  government; including a national DND (do not disturb) registry, to keep  spam SMSs away from unwilling subscribers but in vain. According to a  research there are about 100 million spam messages sent every day in  India by various companies.
This calls for a sure solution to fix  the problem and SMSAssassin promises to be one such solution wherein  spam filtering is automatically done. Professor Kumaraguru and his team  of researchers in IIT Delhi conducted a study and found that an SMS is a  spam or not depends from person to person therefore the software  developed by him filters spam messages and also gives its users freedom  to receive them even if they are spam but still useful to the  subscribers.
The software uses a statistical technique of  filtering spam in e-mail called Bayesian filtering that is combined with  user’s blacklist that uses ‘crowd sourcing’ to identify spam. The crowd  sourcing aspect enables the system to update itself constantly to the  latest trends and changing tactics of spammers and respond quickly to  spam targeted to specific time periods, says Kumaraguru. The technology  is still in its prototype stage and the developers are hopeful to build a  full-fledged system that can be deployed in real time soon.
