Caller Authentication has become a significant concern for call centres, financial institutions and government agencies. The number of suspicious calls where fraudsters seek personal financial information over the phone has increased rapidly since the evolution of VoIP services, such as Skype. Fraudsters use this technology to trick people into divulging confidential financial information through one of the most trusted forms of communication: “The Telephone”
Commonly referred to as Vishing or Voice Phishing, the fraudsters use features facilitated by VoIP. Features such as caller ID spoofing (to display a number of their choosing on the recipients phone line), and automated systems (IVR). Voice phishing is particularly difficult for legal authorities to monitor or trace.
Direct dial numbers and advertised freephone numbers provide the fraudsters with unsecured access routes to directly target their victims
