I think this is interesting and would like to put up a site with a web stream of the lava lamp with a 'generate' button, just for fun and with no intent to profit from it whatsoever.
Could I be sued because of the patent?
I'm also curious on whether or not I can just "not do" one of the claim steps to be sure to not violate the patent.
What is claimed is:
A method for ensuring the security of a system from unauthorized access, comprising the steps of:
digitizing a state of a chaotic system to form a set of binary bits;
applying a hash function to the set of binary bits;
obtaining a seed number from the hash function performed on the binary bits;
inputting the seed number into a random number generator;
using an output from the random number generator to form a password or cryptographic key, wherein the password or cryptographic key is used appropriately by the security system.
So, for example, let's say I simply don't apply a hash function to the set of binary bits (perhaps I encrypt it), but then follow the rest. Would that render patent infringement claims inactionable?
