Abstract

Image Steganography is an art of science that send the secret text by hiding it in the digital image media. The pivotal role of steganography is to send the secret data to the receiver by hide the data in other carrier media to avoid the eavesdroppers with their malicious act. It also focuses on the quality and hue of the carrier image and it should be more complex for the eavesdropper to tap the information. This paper innovates a novel strategy to hide the secret text in an image by implementing spiral pattern, cryptographic technique for data processing and Least Significant Bit (LSB) substitution method for embed the data in the carrier media. Initially the secret text is to be shuffled by the spiral pattern and this shuffled text is supplied for the further process. Then the shuffled secret text is to be encrypted by the Data Encryption Standard (DES) with secret key, under cryptographic techniques to make this approach as more secure. Then using the LSB substitution method, the cipher text has to be embedded in the carrier image. After this embedding process, the carrier image is ready to transfer via the public network. In the receiver side, the system has to fetch the cipher text from the carrier image and then decrypt the cipher text using the secret key by DES cryptographic technique. Then this decrypted text to be rearranged using the spiral pattern. This process will retrieve the secret message. This approach is more secure than other secret message transfer techniques, by implementing the three levels of security, initially text shuffling, then encryption by DES cryptographic method and finally hiding bits using LSB.
