MTSP-LDP: A Framework for Multi-Task Streaming Data Publication under Local Differential Privacy

Summary: MTSP-LDP: w-event LDP framework for streaming publication beyond per-timestamp stats, supporting complex multi-task queries. Key idea: temporal-correlation-aware budget allocation plus adaptive private binary tree, grouping/smoothing, and budget-free multi-task processing for higher utility.
