Grid computing is one of the fastest emerging technologies within the high performance computing environment.Grid deployments that require access and processing of data are called data grids. They are optimized for data oriented operation. In a data grid environment, data replication is an effective way to improve data accessibility. Here data partitioning and dynamic replication in data grid are considered. In which security and access performance of a system are efficient. There are several important requirements for data grids, including information survivability, security, and access performance. More specifically, the investigation is the problem of optimal allocation of sensitive data objects that are partitioned by using secret sharing scheme or erasure coding scheme and replicated. DATA PARTITIONING is known as the single data can be divided into multiple objects. REPLICATION is known as process of sharing information (i.e.) storing same data in multiple systems. Replication techniques are frequently used to improve data availability. Single point failure does not affect this system, where the data will be secured. General Terms: Performance, Reliability, Security
