SSB-7: A New Image Steganography System for Messsage Insertion Chance Enhancement using Bit 7
نویسندگان
چکیده
In this paper, a new Image Steganography method based on the spatial Domain is proposed. It does not use the known LSB’s bit to embed the message. It uses the bit 7 of pixel value of cover image. The main idea is to make the bit 7 of pixel value equal to the message bit by adding or subtracting 1 to the pixel value. Our method is imperceptible to HVS because it provides minimum degradation in image quality due to only +1 or -1 change at a pixel value. Our method also provides 99.21% chances of message insertion at a pixel value which is near about optimal solution. We have compared our method with other methods in spatial domain by using various image steganography parameters.

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 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 کاملImage/message Steganography using LSB insertion Algorithms for DRM system
Digital Rights Management (DRM) system is the effective scheme for digital transactions. The main disadvantage of DRM is that once the content is decrypted, it can be easily copied using widely available utilities. It can be removed by using protection system like steganography. Steganography is the art of communicating in a way which hides a secret message into the main information or cover. T...
