| Abstract | : | Information hiding is the most important method in hiding secret information from unauthorized party. The purpose of information hiding is to protect the secret information. One of the method commonly used is steganography. In this research, Cascaded Image Steganography based on spatial and transformational domain is proposed. This method utilizes two steganography algorithms and double cover information hiding. There are two main processes which are encoding and decoding. The encoding process consists of two steps which are Encoding level-1 and Encoding level-2. The decoding process also consists of two steps which are Decoding level-1 and Decoding level-2. The robustness test is then performed against stego image that undergo images processing operations such as filtering, cropping, rotating, and compression. The results show that stego image undergoes filtering has SNR value of 53.6361 dB indicating good picture quality and high fidelity, whereas stego image undergoes JPEG compression has SNR value of 52.7693 dB indicating good picture quality and high fidelity. Image undergoes rotating(-) has poor image quality indicating low fidelity level, whereas image undergoes rotating(+) and cropping has unusable image quality indicating very low fidelity level. The Cascaded Image Steganography method is more secure due to the double cover information hiding. |
