Abstract: Methods, systems, and devices are described for wireless communication to enable data collection from wireless devices in an efficient manner. An aspect of the data collection approaches described herein may involve determining a smaller group of wireless devices from which to collect data. Determining the group may be performed such that the data collected is representative of the wireless devices as a whole. For example, a statistically significant group of wireless devices may be selected to be statistically representative of the wireless devices of the network. Various criteria may be identified for selecting the group. Such criteria may include a specified technique for selecting wireless devices for the group.

Abstract: Electronic devices are adapted to generate cryptographic keys from one or more biometrics. According to one examples, an electronic device can obtain a non-encoded bit string associated with biometric information for an individual. The non-encoded bit string can be treated as if it were encoded and a decoding operation may be applied to the bit string, resulting in a modified bit string. One or more cryptographic keys can then be generated based at least in part on the modified bit string. Other aspects, embodiments, and features are also included.

Abstract: The disclosure relates in some aspects to protecting systems and data from maliciously caused destruction. Data integrity is maintained by monitoring data to detect and prevent potential attacks. A mechanism for tracking whether data is tainted is implemented in a Data Flow computer architecture or some other suitable architecture. In some aspects, a taint checking mechanism is implemented within a register file, memory management, and an instruction set of such an architecture. To this end, an indication of whether the data stored in a given physical memory location is tainted is stored along with the physical memory location. For example, a register can include a bit for a corresponding taint flag, a memory page can include a bit for a corresponding taint flag, and an input/output (I/O) port can include a bit for a corresponding taint flag.
