사이버사기 범죄단서 공유를 통한 예방 및 대응방안에 관한 연구

Abstract

In this paper, in order to prevent Cyber fraudulent crimes in direct transactions, we propose a system that shares information on suspected cyber fraud sales that cannot be disclosed under the Personal Information Protection Act among the cyber fraud sales suspect information obtained by second-hand dealers after pseudonymization. Cyber scams account for 74% of crimes using authentic internet networks, of which 70% are direct trading frauds of used items. Since direct transaction fraud occurs on Internet secondhand trading platforms, it is desperately necessary to establish measures to prevent it. If we analyze recent cyber fraud damage cases and make account numbers and phone numbers out of the criminal clues into pseudonyms, combine them with other tranding information and share them between second-hand trading companies, we will block, caution, and notify you of fraudulent sellers and items that overlap with each other. It has been proven that it can prevent the spread of damage and inform the counterparty of the risk of fraud by checking the damage report history for account numbers and phone numbers. It is judged that cyber fraud crimes can be effectively prevented if second-hand transaction companies and those subject to second-hand transactions share and actively utilize the information on criminal clues and cyber fraud damage report history information about cyber fraud crimes through the platform.
