Abstract: A solid modeling and non-fungible virtual and anti-counterfeiting integration system mainly comprises a 3D modeling device, an elliptic curve cryptographic module, and a non-fungible transaction platform. The 3D modeling device mainly obtains a 3D image file with a characteristic value from a physical object, the elliptic curve cryptographic module generates a sub-public key and a sub-private key, and the non-fungible transaction platform comprises a master private key and a master public key. The sub-public key is capable of encrypting the characteristic value, the sub-private key decrypts the sub-public key to restore the characteristic value and display the 3D image file, the master private key signs the sub-public key and the sub-private key, the master public key verifies the signature, by obtaining the sub-public key and the sub-private key, the sub-private key is capable of decrypting the sub-public key to restore the characteristic value and display the 3D image file.

Abstract: A system for issuing and converting virtual currency in a physical voucher manner and a method thereof are provided. The system comprises a host server, a mobile device, and an application integration system connected to the host server and the mobile device. The host server comprises a first storage unit including a first database for storing a plurality of pieces of virtual currency data. The mobile device is configured to receive an authentication code from a user. The application integration system comprises a second storage unit including a second database for storing a plurality of pieces of comparison data and is configured to receive the authentication code from the mobile device, and to generate a coincident signal after analytically comparing the authentication code with the pieces of comparison data. The coincident signal is further transmitted to the host server for further analytical comparison with the pieces of virtual currency data.
