1. A method for establishing secure communications, comprising:

  • measuring one or more human gestures using a sensor on a first device so as to create a first metric based on the one or more human gestures that includes time-based information corresponding to the one or more human gestures;

    creating a strong encryption key based on the first metric, including the time-based information incorporated into the first metric;

    communicating to a second device using the strong encryption key to encrypt data sent to the second device; and

    performing an authentication between the first device and the second device including;

    creating a first handshake string based on a communication initiation time, a unique device identifier of the first device and the first metric;

    sending the first handshake string to the second device;

    receiving a second handshake string from the second device, the second handshake string created using the communication initiation time, a unique device identifier of the second device and a second gesture-based metric created at the second device; and

    verifying an identity of the second device using the second handshake string using pre-stored information including the unique device identifier of the second device and a reference image associated with the second device.
