Data Security using NFC technology

Data Security using NFC technology
>> These three genius guys Renato Amez, Andrew Chien & Roger Young have made Data Security using NFC technology project at cornell university.
>> Project description in their own words “Our group chose to implement a secure form of storage for sensitive information such as passwords or identification numbers. This is modeled after Shamirs secret sharing algorithm. It allows us to distribute information regarding the secret key among several agents. In this way, you would need a certain minimum threshold number of agents to collaborate to generate the secret key. With this base concept down, we needed a way to physically store and distribute this information. We decided to use Near-field communication (NFC) as the medium through which to transfer information. NFC builds on top of RFID and was chosen for both its limited range and versatility. Our current implementation stores information on NFC cards, but future enhancements can allow communication with other devices such as NFC-enabled phones. For demonstration purposes, we combined both the encoder and decoder into one device. The user can specify the number of agents and the threshold number to encode a certain key. The other option is to use the Advanced Encryption Standard (AES) to encrypt the data and store it on a single card. The user is able to choose either option and interact with the device through a keypad and a television screen.”
