Privacy preserving and data security — A survey

Privacy is the major concern in the present world today. Data is also playing the major role and how the data is secured in the network is the trivial task. When the data is transmitted in the network, it is initially encrypted and the information is secured with minimal crypto security features. The information is more secured with public and private keys and during retrieval the data is to be decrypted with the same. The information is gathered and transmitted but how to provide privacy to the data in network is the concern. Data that is shared in the network, are to be made private and more secured. By privacy we can preserve the data in any channel and transmit it with security and its standards. The paper discusses on how the recent trend is working on data and its security. The paper also tells about the various cryptographic algorithm used during data transmission.
