Abstract: Various embodiments may provide communication security at a physical layer. In some embodiments, a first wireless device at a first location may transmit to a second wireless device at a second location different portions of a message via two or more different spatially separated signal paths in a manner that enables the second wireless device to receive the complete message but prevents reception of the complete message by a third wireless device at a third location different from the second location. The second wireless device may receive different portions of the message via the two or more different spatially separated signal paths, may assemble the message from the received different portions of the message.

Abstract: Embodiments include systems and methods for analyzing content of a media presentation within a receiving computing device. In embodiments, a processor of a computing device may analyze media data within a media bitstream while receiving, such as prior to or in parallel with presentation of, the media data to determine whether the media data includes objectionable content. The processor may modify a presentation of the media data in response to determining that the analyzed media data includes objectionable content. The computing device may be a wireless communication device.
