Towards Privacy-Preserving Travel-Time-First Task Assignment in Spatial Crowdsourcinghm to securely calculate the least common multiple (LCM) of every workers speed, based on which expensive division operation on ciphertexts can be avoided. We formally prove that our protocol is secure against semi-honest adversaries. Through extensive experiments over real datasets, we demonstrate

Discussion on Fast and Accurate Sketches for Skewed Data Streams: A Case Studynlargement and hierarchy for accuracy, word acceleration and hash bit technique for speed play the central role in the improvement, but they also have limitations and side-effects. Other properties of working sketches such as deletion and generality are also discussed. Our discussions are supported
