One of most common and continuous problem faced by any website owner is spam registration and spam enquiry submitted from website. With increasing usage of website for enquiry generation, he search for fool proof spam filter is going on with two objectives to achieve :-
1. Effectively eliminate any spam registration while not rejecting valid registration
2. Not to annoy prospective client enough not to discourage from registration but perform some prior verification.
Anti-spam human readable images, CAPTCHA, is one of the most popular and widely used method used by websites to fight spam registration by automated bots. While it is effective to filter spam and non serious registration, it still faces challenges of difficult images which are difficult even to human eye to read and thus scare away many people from submitting enquiry.
IVR (Interactive Voice Response) System can be used not only to fight spam, but also to verify phone number.
The process is very simple actually! Every registration or enquiry form will have a field for entering a valid phone number. The registration is not complete till the registrant does not give a “missed call” to IVR number!
1. Every registration will be inactive till the registrant calls to IVR number though the other records in the registration form will be stored in a database.
2. As soon as the IVR receives the call, it will match with inactive registration int he database with phone number, if it matches, it will disconnect the call without picking up the call( So no charge to the caller) and verify both the phone number as well as the registration.
3. Alerts about the new verified registration can be sent out to concerned personals.
Few advanced options which can also be incorporated:-
1. The IVR number could be dynamically changed.
2. The “missed call verification” would be valid for fixed time, say 10 min or so within which the registrant has to give the “missed call”.
3. Verification Number could be asked to enter by the IVR (shown on the registration form) in order to use another level of authentication.
Advantages of IVR based spam filter:-
1. It does not uses difficult and intimidating CAPTCHA, but just a phoen call which is one of the easiest tasks performed by anyone daily.
2. It not only validates the registration, but also verifies the phone number to be active and working! Yes, one can immediately give a call back if its a sales enquiry!
3. It is very fast and requires minimal efforts unlike email verification.
4. It is almost 100% accurate as it involves a valid phone number.
