Abstract: A non-transitory computer-readable medium encoded with a computer-readable program which, when executed by a processor, will cause a computer to execute a method of authenticating a 3-D object with a 2-D camera, the method including building a pre-determined database. The method additionally includes registering the 3-D object to a storage unit of a device comprising the 2-D camera, thereby creating a registered 3-D model of the 3-D object. Additionally, the method includes authenticating a test 3-D object by comparing the test 3-D object to the registered 3-D model.

Abstract: A non-transitory computer-readable medium encoded with a computer-readable program which, when executed by a first processor, will cause a computer to execute a method of authenticating a user, the method including training a plurality of models. The method additionally includes sending, by a computer, an acoustic signal. Further, the method includes receiving, by the computer, a reflected acoustic signal, wherein the reflected acoustic signal comprises information about a signature. Moreover, the method includes receiving, by the computer, motion data about the information about the signature. The method additionally includes comparing the information about the signature to a model to generate a score. Additionally, the method includes deciding, based on the score, if the information about the signature is within a predetermined tolerance level.

Abstract: A method of selectively broadcasting a message to a client by a server without knowing the client's internet protocol (IP) address includes performing target recognition and tracking on one or more targets, including position of the one or more targets, extracting target-specific context parameters from the one or more recognized and tracked targets, encoding the target-specific context parameters into a header, thereby generating a context address for the one or more targets, appending the context address to a message for the one or more targets from a predetermined set of messages based on the position of the one or more targets, thereby generating one or more packets of information, and broadcasting the one or more packets wirelessly to one or more client mobile devices each associated with the one or more targets.
