Logistic and Tent Map Encrypted Image Steganography in Transformation Domain using DWT-LSB Technique

Abstract

The data confidentiality in an image is predominant in digital-world and outstretching the importance. Steganography and Cryptography are generally used for securing information. The security level is enhanced by encrypting the secret image using dual chaotic system models to generate random encryption sequences using Logistic and Tent map in proposed algorithm. The encrypted image is inserted into another image in transformation domain using DWT-LSB steganography techniques. Proposed method is robust and providing high information security with a good SSIM and PSNR for encryption process and embedding process respectively
