Do you ever wonder if people are only not mad at the things that make you mad, because they didn't see them first? I wonder that sometimes.

I also wonder if there's a practical application to the idea of smart-read RFID tattoos, with encrypted, scrambling frequencies (daily cycle), such that those tattooed with them would have access to certain areas, and those without would be restricted. Not just standard tags, but the frequency encryption and cycling, that's what makes it different.

Is it viable?

It would either have to have a matching cycle (tattoo goes through large primes, scanner looks for large primes) (I especially like the idea of a pseudo-fractal tattoo keyed to a second clock starting from the assassination of Rasputin), or have some shared quality for which the scanner could identify (along the line of whether this construction has 'the Buddha nature' from the game Zendo: if the tattoo has three dots in a line, let them in, and the tattoo shifts between zillions of different images, all happening to contain three dots in a line).

The problem being, any pattern can be cracked.
The pseudo-fractal (I say pseudo because fractals are infinitely repeating and we can't represent that given the physical constraints; no matter how small you draw, there's always a smaller layer, part of the definition of a fractal) that's changing every second would be very very difficult to 1)figure out the pattern, 2)replicate the pattern, and 3)get the pattern into the right place at the right time... but it would still be possible.
Assuming the dots in question are microscopic, the shared pattern would be more difficult to figure out, but easier to replicate and break in once it is figured out.

Either way you'd want the tattoo to run on bio-energy, and disassemble if it were ever removed. (not self-destruct, in case the person has a stroke or some other disruption)

That's a much more physical, but still really interesting idea thatn I'm looknig at, here. I'm just looking at tumbling the radio frequency, every twenty-four hours, such that the nearest radio reader, with the decryption key, recognises the person or persons.

The actually moveable patterns could be an added optical layer of the encryption, though, so we get radio and visual requency, for added security.

Two sets of keys would, indeed, make for the better security.

I'm not sure how I missed the "radio" part of your previous message. Same problem, though... if there's a key, it can be cracked. The most secure would be a genescan, until the tech for genetic replication catches up.

I just realized, the tattoo idea's already been presented. "A Beautiful Mind", invisible tattoo with radioactive isotopes and a specifically measured decay. Easily-verifiable, very difficult to duplicate, but still, I'm being less original than I originally thought.
