This technology relates to a security tag, authentication server, and program, which include a memory storing authenticity identification information, an antenna receiving RF signals, a power unit generating energy from received RF, and a control unit transmitting identification information to a reader.
Existing authentication tags had issues with low reliability in authenticity verification because they required a separate power source or were easy to counterfeit or tamper with.
To address this, this technology self-generates power from the reader's RF signal, transmits identification information, and authenticates it on a server, thereby enabling highly reliable, power-free authenticity verification.
This invention is the result of the project 'Development of High-Quality Cryptographic Key Generation and Core Security Technologies Based on Electrical Signals for Secure 4th Industrial Services,' conducted with support from the Ministry of Science and ICT.
