Digital Image Steganography Concept and Evaluation
نویسنده
چکیده
Steganography is the art of hiding the fact that communication is taking place, by hiding information in other information. There are many steganography techniques with different kind of container. Digital image are the most popular and frequency used on the internet. In this article we consider the main image steganography techniques and those advantages and disadvantages. Also attempt to identify the requirements of a good steganography algorithm and evaluation these algorithms.

Steganography Scheme Based on Reed-Muller Code with Improving Payload and Ability to Retrieval of Destroyed Data for Digital Images
In this paper, a new steganography scheme with high embedding payload and good visual quality is presented. Before embedding process, secret information is encoded as block using Reed-Muller error correction code. After data encoding and embedding into the low-order bits of host image, modulus function is used to increase visual quality of stego image. Since the proposed method is able to embed...
متن کاملOptimizing image steganography by combining the GA and ICA
In this study, a novel approach which uses combination of steganography and cryptography for hiding information into digital images as host media is proposed. In the process, secret data is first encrypted using the mono-alphabetic substitution cipher method and then the encrypted secret data is embedded inside an image using an algorithm which combines the random patterns based on Space Fillin...
متن کاملSecret Information Steganography Using LSB Insertion Methodwithout Bit Layout Section with Increasing Substitution Rate and High Reliability
In this paper, a faster method for embedding cryptographic information in the image ispresented by expressing the concept of latent prints (Steganography). Data is encrypted bytwo methods before embedding to increase reliability. Then they are embedded into the imageby a button, a method has been expressed to reduce potential noise impact on the wayinformation is encoded.
متن کاملA Novel Patch-Based Digital Signature
In this paper a new patch-based digital signature (DS) is proposed. The proposed approach similar to steganography methods hides the secure message in a host image. However, it uses a patch-based key to encode/decode the data like cryptography approaches. Both the host image and key patches are randomly initialized. The proposed approach consists of encoding and decoding algorithms. The encodin...
متن کاملمروری بر روش های نهاننگاری در JPEG و بررسی امنیت آن ها
Abstract: JPEG is the most applicable image format in digital communication. In recent years, various steganography methods have been proposed for it. This paper aims to study and classify JPEG steganography schemes and introduce different methods to improve their security based on cover. Accordingly, the effective factors in security that are related to the cover such as double compression, sp...
