Atlanta-based Whisper Communications LLC was founded in 2009 to commercialize physical layer security technologies developed at the Georgia Institute of Technology. The company focused on technologies where data security is tied to proximity to the data source. Target markets included radio-frequency identification (RFID), access systems, short-range wireless communications, passport/credit cards, mobile pay near field communications (NFC), and secure cloud storage.
