An Efficient and Secure Hiding Technique for Fingerprint Authentication Based on DNA Sequence

Information security is earning more attention due to the increase in the size of the data being exchanged over the network. One of the suggested solutions to preserve the secrecy is the cryptography of the information by turning them into codes before the data transfer. The stenographic technique is another way to protect the information, and it is based on hiding the information from the advisory. Cryptography and steganography are methods that allow the information to be sent securely. Current studies suggest that the integration of cryptography and steganography techniques will provide more security and confidentiality compared with the application of each technique individually. The DNA steganography uses the DNA sequence as a carrier to enable secure transfer of the critical data. The principle of this technique is basically to encrypt and conceal messages within high capacity of DNA strands to prevent adversaries from reading and deciphering the messages. This research intends to develop a technique that integrates the sciences of steganography and cryptography to protect the secret fingerprint image in the communication channel and to preserve the confidentiality of the information.
