Meet Dhwani: A Secure NFC Alternative Built In India

The team consisting of Rajalakshmi Nandakumar, Krishna Kant Chintalapudi, Venkata N. Padmanabhan and Ramarathnam Venkatesan have laid emphasis on secure communication by implementing 'JamSecure' technology to prevent eavesdropping. âJamSecureâ uses self-jamming coupled with self-interference cancellation at the receiver. This means that when the data signal is transmitted across the channel a noise signal is also transmitted along with it that can only be removed by the receiver unit. Any eavesdropper trying to intercept the data shall only be able to pick up the muddled signal instead of the original one.
This technology could have a huge impact on the mobile devices sector as it will help enable extensive NFC applications. Since this is only a software implementation, users can just download an app and achieve NFC functionality on their existing phones. Apple users shall be particularly interested in this development as the Cupertino giant has never brought NFC to its devices.
