How to achieve the anti-counterfeiting function for IOS based on the NFC tag

As we know, the ios can only read the ndef message, and the ndef message is in the public area and is unencrypted, therefore, how could we identify the NFC tag is unique and is not a copy one, (except using the UID). Even, can we put a private key into the tag and the ios can get it, do you have a solution for this problem, and give us some advises.
One more question, for ICODE tag(Type 5, 15693), we would like to confirm which tag(specific model) support the UID and counter mirror features(mapping the UID and counter value into the ndef area);
looking forward your reply, and thank you very much!
