Call for papers Special Issue in Journal of Parallel and Distributed Computing on "Theories, Algorithms and Modeling for Privacy Computing" Special Issue website: https://www.journals.elsevier.com/journal-of-parallel-and-distributed-comput... *Introduction* With more data including personal information being hosted online such as cloud, privacy leakage is becoming one of serious concerns in online community. In practice, different temporal, spatial or application cases often demand different privacy protection solutions. Most of traditional approaches are case by case or based on a specific application circumstance. Therefore, we need to develop a systematic and quantized privacy characterization towards systematic computing model describing the relationships between protection level, profit and loss as well as the complexity of integrated privacy protection models Privacy computing is emerging as a paradigm to systematically scope privacy protection and related techniques. This special issue focuses on fundamental challenges of privacy computing – theories, algorithms and modelling while applications and general principles are not in the focus. Papers on theoretical foundations and algorithms with strong analytical contributions are encouraged for submission. *Topics of interests include, but are not limited to:* · Parallel, Distributed and Scalable modelling for privacy protection · Theories and foundations for privacy computing · Languages and compilers for privacy computing · Privacy computing model and modelling · Privacy quantification, formal description · Privacy operation and modelling · Data utility and privacy loss theories · Context adaptive cryptography or privacy protection · Data analytics oriented privacy models and reasoning · Private information exchange and sharing models · Privacy inference and reasoning *Submission Instructions* Before submitting your manuscript, please ensure you have carefully read the Instructions for Authors - https://www.journals.elsevier.com/journal-of-parallel-and-distributed-comput.... The complete manuscript should be submitted through the journal website submission system.
