Data leakage is big security threat to organization, when third party agent carried out data leakage. Perturbation method use for the detecting and preventing data leakage and also for assessing data third party agent. Firstly, watermarking techniques used for data leakage but in that techniques modification to original data take place. To overcome this disadvantage data allocation strategies is used. It improve feasibility of finding guilt agent. Data based on sample request and explicit request using allocation strategies allocate by the distributor to detect the agent. Fake object are given with original data. If one or more fake object is leaked, then distributor detect the leakage by the agent was guilty. So, perturbation is efficient technique handle data leakage and also make less sensitive to data before handle to agent.
