Personal ip protection system and method

A personal intellectual property (IP) protection method comprising:

• when a terminal performs an electronic contract function with another terminal for IP to which a user of the terminal has a right, transmitting, by the terminal, an electronic contract generated in relation to electronic contract, IP information related to the generated electronic contract, and identification information of the terminal to a server;
• encrypting, by the server, the electronic contract using a preset personal key;
• transmitting, by the server, the encrypted electronic contract, the IP information related to the electronic contract, and the identification information of the terminal to a blockchain server;
• and
• registering, by the blockchain server, the encrypted electronic contract, the IP information related to the electronic contract, and the identification information of the terminal, which are transmitted from the server, in a blockchain in the blockchain server,
• wherein the encrypting of the electronic contract using the preset personal key includes:
• generating a random number code having a preset number of bits;
• applying the generated random number code to a preset hash function to generate a hash value;
• extracting a preset bit section from the generated hash value;
• applying the extracted bit section to another preset hash function to generate a personal key and an encryption key including a public key;
• and
• encrypting the electronic contract using the generated personal key, and
• the terminal is configured to publish a work produced by the user of the terminal and posts a license agreement for the published work through the server so that another user of the another terminal checks the license agreement for the work produced by the user, and the terminal interworks with the another terminal that checks the license agreement to proceed with the license agreement for the work produced by the user in a form of the electronic contract.
