Some thoughts on RFID Privacy Protection

Key points for privacy

·         Minimize sensitive data on the chip.  Store only necessary data.

·        Use a Faraday Cage – something to protect against unauthorized signal penetration.

·         Encrypt the data. Only those authorized know encryption algorithm.

One major protection option: The use of jackets for passports, credit cards, ID cards, etc. There are plastic shields that are an electromagnetically opaque sleeve available.

Verayo employs their PUF Technology for secure access ti the RFID. The PUF technology adds multiple challenge response system for access that can store 2⁶⁴ possibilities. The challenge response changes after each use.
