Whisper NFC Beam is an application for near field communications (NFC) enabled Android devices. The application implements Whisper Communications' patented technology (a.k.a. Whisper Cone of Silence) to secure peer-to-peer file transfers when two Android devices communicate via NFC/Android Beam. The file to be transmitted is whisper-encoded (based on a password set by the sending user) before it is transmitted via Android Beam. Since the password can be changed by the sending user for each transmission, it makes the data transfer secure against eavesdropping/sniffing.

INSTRUCTIONS:

(1) The sending user launches the application, selects the file to be sent, and sets the password for the NFC transmission.

(2) Once the password is set, the sending user presses the "send" button and the "Tap with another device to push the data" message appears. The sending device is then tapped to the receiving device and Android Beam (over Bluetooth) is initiated.

(3) Once the beaming is complete, the receiving user is notified via the notification bar.

(4) The receiving user opens the received file from the notification bar with the Whisper NFC Beam app (or locates and opens the file from the "beam" directory).

(5) The receiving user enters the correct password. The file is then whisper-decoded and stored with the file name "ReceivedFile.Whisper" in a folder named "WhisperNFC" on the SD card/USB data storage.

(6) The receiving user can then display the contents and/or change the name of the received file with one of the many file manager applications available on Google Play.

NOTES:

(1) This application can transfer any file type and is not limited by the standard Android Beam file types. Before transmission, the sending device whisper-encodes the file and stores it as "whisper_NFC_beam.c" on the SD card/USB storage under the "WhisperNFC" folder.

(2) Both NFC and Android Beam have to be turned on in the settings for both Android devices.

(3) Both the sending and receiving Android device need to have the Whisper NFC Beam app installed.
