Cryptography is the method of transforming the original texted message into an unknown form and in reverse also. It is the process of hiding and forwarding the data in an appropriate form so that only authorized persons can know and can process it. Cryptographic process secures the data from hijacking or transmutation, it is mainly used for users data security. This paper justifies the encryption and decryption using DNA(Deoxyribo Nucleic Acid) sequence. This process includes several intermediate steps, the perception of binary-coded form and generating of arbitrary keys is used to encrypt the message. A common key should be established between the sender and receiver for encryption and decryption process. The common key provides more security to the sequence. In this paper, both the process of binary-coded form and generating of arbitrary keys are used to encrypt the message. It is widely used in an institution and by every individual to hide their data from the muggers and hijackers and provides the data securely, and confidentially over the transmission of information.

Management of flow of all kinds of objects including human beings signifies their real time monitoring. This paper outlines the advantages accrued out of biometrics integration with Smartcards. It showcases the identity authentication employed through different biometric techniques. Biometric key considerations influencing the essence of this technology in Smartcards have been discussed briefly in this paper. With better accuracy and highly reliable support system this technology finds itself today in widespread deployment. However, there are still some concerns with human interfaces along with important factors in implementations of biometrics with smartcards which have been highlighted in this article. This paper also examines the privacy concerns of users in addressing their apprehensions to protect their confidentiality through biometric encryption and proposes DNA technology as a best possible biometric solution. However, due to inherent limitations of its processing time and an instant requirement of authentication, it has been suggested in the proposed modal to use it with combination of one or more suitable biometric technologies. An instant access has been proposed to the user with limited rights by using biometric technology other than the DNA as a primary source of authentication. DNA has been proposed as secondary source of authentication where only after due sample comparison full access rights to the user will be granted. This paper also aims in highlighting the number of advantages offered by the integration of biometrics with smartcards. It also discusses the need to tackle existing challenges due to restrictions in processing of different biometric technologies by defining certain specific future scopes for improvements in existing biometric technologies mainly against the time taken by it for sample comparisons.
