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.

Disclosed is an apparatus, system, and method to utilize road markers to control vehicle speeds. The road markers may be commanded to emit a light for a pre-determined period of time. Further, the road markers may be controlled such that they are commanded to emit the light based upon a timing sequence associated with a desired speed so that the road markers emit light in a strobe pattern. In this way, if a vehicle is traveling at the desired speed, then the strobe pattern appears static to a driver of the vehicle. Additionally, a message may be transmitted from a traffic authority to increase or decrease the timing sequence of the strobe pattern to increase or decrease the speed to the desired speed.
