Privacy Preserving Big data Using Combine Anonymization and Encryption Approach

In recent years, data breach and sensitive information leak is main issue created. Data analysis is done on large amount of data to integrate and analysed data. But it increase data violation in data. To overcome this privacy is need of any particular data and it plays a vital role. Anonymization is a technique which hide the sensitive information of that particular data using generalization and suppression. It increases the privacy of any information. But it is not sufficient as in today’s world many tools are available to break privacy.so we can use protection too to protect the data and by providing dual approach. For this various algorithms are tested among them Paillier encryption proved to be more efficient.
