Abstract: A method including receiving, at multiple cloud computing servers, multiple streaming data sets for the same sensing task each from a respective client device. The streaming data set from each client device comprises sensed data sensed by one or more sensors of said client device. The streaming data sets are encrypted. Each respective streaming data set from a respective client device is divided into multiple streaming data set portions, each to be received at a respective one of the cloud computing server. The method also includes processing, at each respective cloud computing server, the corresponding streaming data set portions received to generate a corresponding share of a result for the sensing task. The method also includes encrypting, at each respective one of the cloud computing servers, the corresponding share of the result; and facilitating creation or update of a blockchain based on the encrypted shares of the result.

Abstract: An electronic storage system and a method of data management includes the steps of: partitioning source data into a plurality of portions of data; storing each of the plurality of portions of data in each of a plurality of storage peers respectively; and storing a plurality of indices in a plurality of storage peers; wherein each of the plurality of indices corresponds to each respective portion of partitioned data; and wherein each of the plurality of storage peers is arranged to store the plurality of indices and the plurality of portions of data in corresponding pairs.

Abstract: A method for processing data and managing information includes receiving, at a server, streaming data from a plurality of client devices; processing the streaming data received at the server to generate useful information from the data; and storing the useful information at the server. The streaming data is encrypted and the server comprises a plurality of cloud computing servers operably connected with each other.
