Civil Aviation Passenger Privacy Information Protection Scheme Based on Blockchain
The ticket and passenger plaintext information for travel verification in the current civil aviation information system had to be obtained,which posed a high risk of passenger privacy information leakage. To address this problem,a blockchain-based solution for protecting the privacy information of civil avia-tion passengers was proposed. Firstly,the real-name registration of blockchain accounts was achieved by utilizing network identity and digital certificate technology to ensure the authenticity of information. Sec-ondly,a secure information authentication protocol was constructed using zero-knowledge proof and ring signature overlay to enable the completely anonymous verification of passenger privacy information and en-sure the anonymous verifiability of real information. Furthermore,K-anonymity technology was employed to desensitize sensitive information stored on the blockchain,thereby enhancing the security of information storage. Experimental results and performance analysis showed that the scheme could provide secure and effective protection of civil aviation passenger privacy information,and the efficiency requirements regard-ing the necessary total time spent on information verification were met.
