Survey and Analysis of Privacy-preserving Based on Horizontal Federated Learning
In recent years,with the rapid development of artificial intelligence,machine learning has become an important approach for data processing.Traditional machine learning methods require data to be uploaded to central servers,which raises concerns about data privacy.However,the distributed nature of federated learning ensures data security and privacy,while also addressing the issue of data silos and improving data availability in different application environments.Nevertheless,increasing research indicates that federated learning methods still face various privacy threats,making it a challenge to protect user data privacy in federated learning scenarios.To address the privacy issues in federated learning,we investigated and analyzed existing privacy protection mechanisms.Firstly,we introduced the definition,development,and classification of federated learning.Secondly,presented the system architecture of federated learning and analyzed the privacy threats it faces.Furthermore,classified and organized privacy protection techniques based on the lifecycle of the federated learning training process,while comparing the advantages and disadvantages of each technique.Finally,highlighted the current challenges faced by federated learning and discussed future development trends.
