Abstract: A cybersecurity system and method utilizing SOUND reputation, where a set of reputations are associated with each actor on a network. The actors on a network may be users, hosts, applications, and the like. The associated reputations are aggregated and updated as new information about an actor's activity is reported according to a defined and modifiable protocol, or policy. The actor's activity may be reported by one or more threat sensors. The effect of a particular misbehavior can be tuned to match the needs of the specific network. When a bad actor's reputation sinks too low, the system can take whatever action is appropriate: reports can be sent, an operator can be notified, the offender can be cut off from the network, or the like.

Abstract: A system produces an interpolated luminance-balanced monochrome image from a Red-Clear-Clear-Clear (RCCC) pattern image. It may include an imager having a RCCC pattern filter array. There is an interpolation processing module with one or more processors processing sampled, red filtered image pixels. A red plane is interpolated using the sampled, red filtered pixels, producing an interpolated red for the pixels. The interpolated red pixels are subtracted from the sampled clear pixels, producing a “Clear minus Red” (“C?R”) plane. A C?R value is interpolated for the red filtered pixels. The interpolated C?R value is added to the sampled red pixels, and the monochrome image is output, where the luminance is balanced across the pixels, especially in low and very light environments.
