- Abstract
Based on the TW16 scheme proposed on ESORICS16, an accurate and efficient privacy protection recommendation algorithm based on homomorphic encryption were constructed. According to the characteristics of active users, the reasonableness and accuracy of the recommendation system were improved by increasing the weight of rank from active users. The efficiency of the system was improved by parameter optimization and adding cache. The experiment showed that compared with the TW16 recommendation protocol, the accuracy of the recommendation scheme was improved. In the data processing phase of strangers, the computation time was reduced by 13. 4%, and the algorithm execution phase of the single prediction protocol was reduced by 12. 7%.
