Abstract: System and techniques for progressive radar assisted facial recognition are described herein. An image may be obtained from a camera of the security device. A facial target in the image may be identified. The facial target may include a non-empty set of positive facial indicators and also be missing a non-empty set of facial indicators used for identification. In response to identifying the facial target, a power level of a millimeter wave radar may be increased at least until a threshold number of members of the set of facial indicators are observed. Then, the members of the set of facial indicators that are observed may be combined with the set of positive indicators of the face to create a composite image.

Abstract: Data is captured by a data capture apparatus in a manner to ensure authenticity of the data to the data capture apparatus. Transducer signaling is generated in response to physical excitation of one or more transducers, and is digitized to produce digital signaling. A cryptographic key is stored in association with the data capture apparatus. At least portions of the digital signaling are digitally signed based on the cryptographic key to produce an authenticatable set of captured data. A security boundary is provided within which the digitizing, storing, and digitally signing are performed. Production of the authenticatable set of captured data is prevented in response to a breach of the security boundary.

Abstract: Technologies for monitoring network access and/or usage include mobile computing devices in communication with network devices to facilitate access to a network. Communication signals are transmitted from one of the mobile computing devices and received by a remote computing device (e.g., a network device). Transients of characteristics of the communication signals received during a power-on sequence of the mobile computing device are analyzed to generate a communication fingerprint corresponding to the communication signal. The network device then compares the communication fingerprint to authorized communication fingerprints to determine whether to grant network access to the mobile computing device corresponding to the communication fingerprint. Additionally, granted network access may be monitored to determine whether any unauthorized use is being performed by the mobile computing device. Further, network access may then be restricted if unauthorized use is detected.
