智能大数据隐私保护机制的构建与实践
Construction and practice of smart big data privacy protection mechanisms
摘要
Abstract
While intelligent big data technology unlocks considerable data value,it also significantly exacerbates the risk of citizen privacy leakage.Based on an analysis of the current status and shortcomings of intelligent big data privacy protection,this study constructs a three-layer privacy protection mechanism comprising'support layer-data layer-control layer'from a technical perspective,incorporating techniques such as data masking,anonymization,dynamic access control,and AI monitoring.The mechanism was validated through simulated testing in a public security scenario.Results indicate that the optimized mechanism improves data processing efficiency by approximately 70.8%,raises the unauthorized access interception rate to 99.2%,achieves zero leakage of sensitive data,and reduces dynamic permission adjustment response time by 95.6%.The study demonstrates that a systematic,full-lifecycle privacy protection mechanism effectively balances data utilization and privacy security,offering a reference for data governance in smart cities.关键词
