Patent attributes
An example operation may include one or more of: receiving, via an input/output interface, an encrypted RF signal from an RF identification device; decrypting, via a processing unit, the received encrypted RF signal to generate decrypted data; modifying, via the processing unit, the decrypted data to generate modified data; maintaining, via a memory, a cryptographic distributed ledger based on the decrypted data and the modified data; encrypting, via the processing unit, the modified data to generate encrypted data; updating, via the memory, the cryptographic distributed ledger based on the encrypted data; and transmitting, via the input/output interface, an updated encrypted RF signal, based on the encrypted data, to the RF identification device.
