Bank Security – Telephone Authentication
I’ve written about bank security before (see Innovation in banking) with concerns over password authentication generally in banking transactions. This evening, I received a phone call from the fraud departments of one of the financial institutions I have a credit card with wanting to discuss my account. I immediately asked for their details and called back on a known number and was put through to the person in question.
At the end of the call this individual advised me that I could always identify them as a legitimate caller by having them provide me with some personal information about me. Although they have called me on a known number they have listed for me, if for example I had my wallet and mobile phone stolen, then calling me on my mobile phone would alert thieves that the bank fraud department was onto them.
Although banks are getting a lot better (certainly with respect to having no objection to a request for a customer to call them back), some more thought needs to be put into this process in the world where identity theft is becoming increasingly common.
