Imagine you got verification call from SBI or Axis bank or any other service providers, Caller will tell you that he/she called from so n so bank, and will ask fpr sensitive information like birthdate, mothers maiden name, registered address.  You cannot verify if call is from trusted source as you cannot guess it from number.  You never know you might be exposing secret information which can be used to hack your email or bank accounts or duplicate credit cards.
 
Also at the airport, if you have booked flight using Credit card, you need to submit xerox of your credit card, god knows what do they do with it. They should not ask it.

This survey is seek answers to few questions and feedback from you about current malpractices of verification calls in general domain which violates privacy norms.

This survey is done by http://twitter.com/sandipmore , out of curiosity, for a social cause.

I want to see how many people are concerned about fraud happening over unsolicited verification calls from banks and other companies.
I also want to find out solutions are in place or need to be there, to verify sources of these calls.
