Due to COVID-19, social life has changed rapidly, and non-face-to-face classes and video conferencing services have been becoming commonplace in various fields. Information generated during the meeting should be stored and secured as necessary. Blockchain technology is widely used to enhance the security of data storage and management systems. In particular, research on the application of blockchain to various fields and application systems as a method to prevent data forgery and falsification is active. In this study, we propose a video conference data security method using blockchain technology. In the video conference system, authentication through smart contract, block chain data generation method, block chain server connection structure and implementation examples are presented, and data confidentiality, data integrity, and service practicality of the block chain network structure centered on the representative block chain server are discussed. Based on the private blockchain, the electronic signature of meeting participants obtains consent to store information and blocks the stored information. In the proposed system, data confidentiality is maintained through a permissioned blockchain structure and smart contract. Implementation and operational practicability can be improved by maintaining the the integrity of data through chaining and decentralization of the block chain, and delegating the block chain data to the block chain server instead of the user owning it. In addition, it can be a solution to prevent fraud by a server administrator in a centrally managed system. |
