DATA PROVIDING SYSTEM AND DATA PROVIDING METHOD
Document Type and Number:
WIPO Patent Application WO/2023/152989
Kind Code:
A1
Abstract:
This data providing system (1) comprises: an encryption device (10) which generates encrypted NC data (51) by encrypting, by using a first encryption key, NC data (50) used by a numerical control device that controls a machine tool or a simulator that simulates the operation of the machine tool; a storage device (30) which stores and distributes the encrypted NC data; an authentication management device (20) which receives, from the encryption device, an NC data decryption key (A2) corresponding to the first encryption key and generates a payment authentication code (C1) with a first decryption key stored therein, and outputs the payment authentication code; and a decryption device (40) which extracts the NC data decryption key from the payment authentication code, and extracts the NC data by decrypting the encrypted NC data by using the NC data decryption key.
