How good is LavaRnd?

The Heisenberg Uncertainty Principle can be used to show that you will fail in your ability to perfectly model the physical conditions that lead to CCD noise.

The inability to perfectly predict the physical processes within the CCD rests on the Heisenberg Uncertainty Principle of theory of quantum mechanics. The digital luminance output of a CCD frame is a measurement of the physical state of the device. The Heisenberg Uncertainty Principle says that not only will this measurement be imperfect, but the very act of taking the measurement will disturb the physical conditions of the CCD device itself.

The chaotic nature of the webcam CCD means that the slightest mistake predicting its physical state now will quickly render future predictions completely useless.

Not only does the Heisenberg Uncertainty Principle frustrate your ability to perfectly predict a given frame, it makes your imprecise measurement useless as a tool to replay past frames or predict future frames. Even a small error in predicting a given frame casts doubt upon your ability to approximate the potential luminance values of the next frame. The uncertainly of one frame is compounded with the error in taking the next frame measurement. Due to the nature of chaos, uncertainly of luminance values of a given frame is amplified to produce even greater uncertainly about the next frame.

You have no better chance of accurately predicting the state of the high gain lens-capped webcam CCD than you do in making accurate long term weather forecasts.

The high gain of the lens-capped webcam CCD produces noise that cannot be predicted with absolute certainty. Even the act of taking luminance measurements disturbs the underlying physical state of the CCD in an uncertain way. The error of one frame is compounded with the imprecise measurement of the next frame. This chaotic compounding quickly dominates all calculations making prediction of future frames based on the current frame intractable.

A wrong guess for a single bit of a single pixel of webcam CCD luminance usually leads a incorrect guess beyond more than 80 bits of LavaRnd output.

While LavaRnd lacks a formal proof that it is cryptographically strong, one can make the heuristic argument that the Heisenberg Uncertainty Principle and the nature of chaos makes prediction of luminance frame values intractable. The LavaRnd Digital Blender^tm destroys any non-chaotic luminance data. Combined with the uncertainly of the next frame, the LavaRnd output from one frame cannot be correlated with the LavaRnd output of the next frame. Even having the LavaRnd output of a large number of frames renders predicting past or future frame values an intractable problem.
