Cloud computing provides abundant benefits including easy access, decreased costs and flexible resource management. For privacy concerns, sensitive data have to be encrypted before outsourcing, which obsoletes traditional data utilization based on plaintext keyword search.

reduced. To reduce the communication overhead the server should send only the top-n files based on the keyword when the user asks for the data files. Since the owner need not maintain the copy of the files, it is all the more necessary to make check on the files available and also check the originality of the files stored in
Distributed computing framework such asHadoop is now a prominent solution for the efficient big dataprocessing. However, the current data placement strategiesin these frameworks lack in consideration of the types ofstorage devices and the features of surveillance video tasks.So using the current distributed computing framework forlarge-scale video processing in the cloud computing clusterwith hybrid...
queries for given attributes or keywords, we leverage searchable symmetric encryption to design the encrypted local indexes that consider security, efficiency, and data locality simultaneously. Performance evaluation at Microsoft Azure is conducted in terms of Put/Get throughput and latency under different workloads. The
