Many organizations are ready to adopt current communication technology. Cloud service provides various virtual resources in term of hardware and software. It provides large amount of storage space to store large volume of organizations data. Healthcare organizations transferred their patient’s data from local server system to cloud storage. But security is the major problem in cloud storage. So in cloud all the data is stored but at the same time privacy of data in health sector is very important. In the health sector sometime there is a need to take only some specific data. So this research here 2DIIR filter is used to filter the only required messages. 2D IIR filter is the two dimensional filters. The Privacy of the patient data is done using GOWA algorithm in the cloud environment. Analysis of the proposed GWOA algorithm using Hungarian dataset with 256 key size for the metrics, like utility and privacy.
