Disclosed are a method and system for protecting intellectual property rights on digital content using smart propertization. The method of protecting intellectual property rights on digital content includes determining whether to decode encoded digital content based on the digital data indicative of a license for the digital content recorded on a blockchain.
20210334363, "Secure authentication server for smart contract," assigned to Jong Hyeon Kim (KR).
A server which performs secure authentication on a source code for smart contract may comprise a communication unit receiving a smart contract source code from the server requesting secure authentication; and a controller checking security vulnerability based on the received smart contract source code, wherein the controller comprises a source code vulnerability checking unit reading a source code of a smart contract and checking vulnerability in the source code; a communication interval checking unit checking a communication interval for execution of the source code; an execution vulnerability checking unit checking app and web vulnerability on a browser in which the source code is executed; a certificate issuing unit issuing a certificate if it is found from a checking result that a security level satisfies a required criterion and storing the certificate together with the source code in a blockchain block where the source code of the smart contract is stored.
