Secure Blue

IBM Secure Blue

Secure Blue is a type of computer hardware designed by IBM that enables data encryption to be built into a microprocessor. It can be added to existing processors, and encrypts and decrypts data as it passes through them, without requiring any power from the processors themselves. Possible uses of the technology are to protect data on stolen devices and enforcement of digital rights management (DRM).

Blue

Blue is one of the three primary colours in the RGB (additive) colour model, as well as in the RYB colour model. It lies between violet and cyan on the spectrum of visible light. The term blue generally describes colours perceived by humans observing light with a dominant wavelength between approximately 450 and 495 nanometres. The clear daytime sky and the deep sea appear blue because of an optical effect known as Rayleigh scattering. An optical effect called the Tyndall effect explains blue eyes. Distant objects appear more blue because of another optical effect called aerial perspective.
