SAFEGUARDING HIGHLY CONFIDENTIAL MESSAGES IN 7-BIT ASCII USING THE LSB TECHNIQUE IN THE SPATIAL DOMAIN
Keywords:
LSB, Security, Confidentiality, Spatial Domain, Image SteganographyAbstract
With the rapid advancement of technology, a vast amount of data is shared over networks, highlighting the need for strong security measures to protect data confidentiality. Steganography has become a popular technique for securing sensitive messages from unauthorized access. Although many existing image steganography techniques utilize an 8-bit format to convert text into binary, our proposed system enhances security by incorporating a single layer of protection for the secret messages within the spatial domain. In our proposed model, input text is converted into a 7-bit binary format and embedded into the various color channels of each pixel of the cover image using the Least Significant Bit (LSB) technique. This ensures that the changes to the image are not noticeable to the human eye, preserving the image's visual quality. By utilizing these methods, our system increases embedding capacity and strengthens the security of confidential messages, providing an effective way to conceal sensitive information in digital communications without detection
