IMAGE DATA GENERATION SYSTEM, ELECTRONIC DEVICE PRODUCTION SYSTEM, KEY DETECTION SYSTEM AND ELECTRONIC DEVICE

摘要

PROBLEM TO BE SOLVED: To provide an electronic device production system for safely keeping the backup of key data for enciphering or deciphering stored in an electronic device. SOLUTION: A secret key stored in an IC card is embedded in the card background image of the relevant IC card as an electronic watermark. The relevant background image data, a plastic card to become the base of the IC card, and an IC chip equipped with a module terminal, are combined.
