Cloud computing-based services have rapidly developed, but their security aspects are still at the initial stage of development. In order to preserve cyber security in cloud computing, cyber security information that will be exchanged within it needs to be identified and discussed. In this context we propose a new model which is based on Data Asset Decoupling and can provide certain Cyber security Information change environment for any level of Cloud based systems. Here we need an identification criterion for the essential changes to be made in cloud computing and it will emerge the source driven computational environment for the better security aspects. The identification factor for this proposed scheme is Data Asset Decoupling which is a method to the occurrence of returns on asset classes diverging from their normal pattern of correlation.
