Cloud computing provides an economical and efficient solution for sharing group resource among the cloud users. Sharing data in a multi-owner manner while preserving data and identity privacy from an un-trusted cloud is still a challenging issue, due to the frequent change of the members. Mona is a secure Multi-Owner data sharing scheme which leverages the group signature and dynamic broadcast ...

Traditional techniques for measuring similarities between time series are based on handcrafted similarity measures, whereas more recent learning-based approaches cannot exploit external supervision. We combine ideas from timeseries modeling and metric learning, and study siamese recurrent networks (SRNs) that minimize a classification loss to learn a good similarity measure between time series....
