An Irish insurance company had already implemented this technology, using a gps tracker in your car it would track your speed and if you went over the speed limit more than 3 times in any month it would firstly give you warnings then cancel your insurance. It would reduce your insurance but they seem to have stopped using the technology as young male drivers (who were the only ones ment to use this service) didnt sign up in their thousands. I wonder why...
If you "randomly" select a cryptographic system for each stage of the process then you can increase the security of the system. You have to include the systems and in what order they were used in the key. Its down side is that if the number of crytographic systems are not to a power of 2 you are wasting space in you key. On the plus side you remove the problems of each cryptosystem. The attackers knowledge is reduced (depending on your PRNG) and as it doesnt rely on one cryptographic system for its security if the attacker knows an exploit for a system it will reduce the security but should not remove the security completely.
