Part Number: RF37S114

I'd like to implement a simple but secure way of part authnttication with som copy protection based on a RF37S114 NFC tag (ISO15693) in combination with a TRF7964 reader. Is ther a way to store som hidden data to genrate something like a private key? Any other ideas to prevent a mass product from being copied?

Thanks a lot,

Gunter
