Data security is always the focus of huge possible cloud clients, also a big obstacle for its
extensive applications. Till now there is no proficient mechanism for data security accustomed for the
cloud environment, and various service types need different solutions for data protection. The objective
of this research is to develop a new data security model for the cloud environment. The proposed model
is decomposed of four modes of operations denoting the different ways for providing the service for
better user convenience. The four modes are: Scheduling mode, Through-off mode, Virtual machine
mode, and Batch mode. Analyzing the proposed model shows the advantages it has over previous
models. Based on extensive experiments, the proposed model covers many security cases, and is robust
in handling security threats while gaining user convenience.
