Abstract: The system and method of digital steganography comprises a sending AI engine, a decision tree AI engine, an armored security object, and a receiving AI engine. The armored security object comprises concentric layers. The layers of the armored security object can be 3-dimensional and are comprised of at least one axis of rotation, at least one surface, at least one color, and at least one texture.

Abstract: An ultrasound imaging system for use in producing an image of an object in a region of interest includes: an exciter configured to provide an excitation signal; a transducer coupled to the exciter and configured to produce, in response to the excitation signal, an ultrasound field whose complex frequency content varies with field location; a receiver configured to receive ultrasound signals reflected by the object and to produce indicia of the received reflected ultrasound signals; and a processor coupled to the receiver and configured to cross-correlate the indicia of the received reflected ultrasound signals with indicia of the ultrasound field at pixels in the region of interest to determine image pixel intensities of the region of interest for producing an image.

Abstract: A computer program product resides on a computer-readable medium and comprises computer-readable, computer-executable instructions for causing a computer to transmit first indicia for an ultrasound propagation arrangement to propagate ultrasound energy toward a focal region containing an object, receive second indicia from a receiver positioned to receive the propagated ultrasound energy after passing at least one of by and through the object and configured to transduce the received ultrasound energy into the second indicia, analyze the second indicia to determine magnitude and phase of the received ultrasound energy, and use the determined magnitude and phase of the received ultrasound energy and knowledge of the ultrasound energy propagated from the propagation arrangement to mathematically propagate indicia of at least one of the received ultrasound energy and the transmitted ultrasound energy to a common location.
