Abstract : Information passes across the network by means of various path. It is essential to provide security for the information in order to control unauthorized access of data in any form. The data security is ensured by transforming a plain text into unreadable format by encrypting text using cryptographic algorithms. Cryptographic techniques are adopted for encrypting the messages to provide secured communication over a network. It is most important for an organization and individuals to secure their information from attackers and hackers to ensure information privacy, integrity and confidentiality of the data. To enhance the data security across the network it is very significant to encode the data in unreadable form. Many research works is carried out in the evolution of cryptographic system however current development in this field is DNA Cryptography which is developed based on the computational ability of Deoxyribo Nucleic Acid (DNA). The paper proposes a method to implement data hiding using DNA sequence. Here both the concept of binary coding and random values are used and sample DNA sequencing is considered to encrypt the message. The receiver will get both DNA sequence and encrypted data which is then extracted to get the original message. In this method both sender and receiver will share a common DNA sequence for encryption and decryption process.
