An Efficient Encryption Algorithm for Sensitive Data Using Numeric and Alphanumeric Format

In the contemporary world, with the growth of networking and increase in the volume of data storage capacity, a significant amount of personal information leakage accident occurs that leads to loss of personal data day by day. Hence, there arises a need to emphasize more on the security of data stored either in databases or transmitted over the web to ensure that user’s personal data is stored at a safer place. To maintain the privacy and security of data a protective layer of encryption is applied around the sensitive data items focusing on encrypting only the sensitive data. Standard encryption techniques such as AES, DES or 3DES are used to encrypt the data, but these techniques are unsuitable for encrypting personal information as they lead to various shortcomings. In this paper to encrypt personal information a new and efficient encryption scheme is proposed that encrypt numeric data having a length ranging from 1 to 19 such Aadhaar card number, mobile numbers, SSN, IP address, credit card numbers, CVV, and alphanumeric data like email ids. We integrate the proposed solution with various encryption schemes such as Advanced Encryption Standard (AES) on the remote side database. Data transmission and data storage take place at the server database. The remote side and server side database will be secured with the same data formats. Hence, this paper describes an efficient encryption scheme for securing numeric and alphanumeric data of databases.
