Comment Signing for authentication? (Score 1) 229

Beyond the encryption issue addressed in this article, the inclusion of cryptographic features in cameras could offer an authentication feature. Hash the image in its RAW format, sign the hash and store it in the meta data. Do the same thing for the "thumbnail" JPGs that some cameras offer. Now you could tie a given image to a given camera and know that it had not been modified. Of course each camera would need to have its own key pair, and the manufacturer would have to warehouse the private keys and provide the validation service that verified an image was signed by a particular camera ... And there are lots of situations that tying an image to a given camera might not be beneficial. Probably too much work ...

My Dad worked on the Ranging Radar for the Lunar Excursion Module, so I've heard some stories.

Data input was punched cards (duh).

Tests included sticking a unit on the front of a missile and launching across White Sands Missile Range, then comparing the telemetry data returned with a known track mapped across a digitized re-creation of the range. Along the way they discovered the errors in the digitization when the results began claiming that the missile was travelling underground.

One of his research projects was to work out how to apply a new-fangled algorithm to the problem, Fast Fourier Transforms.

Imagine a shell that can adjust it's flight path, even slightly, which means you can fire in the general direction you want, then fine tune the aim in flight. (I assume they don't do that now..)

They don't, and even a railgun projectile probably won't either - because the force required to effect a significant change in trajectory (especially in azimuth) is simply too great.
