Abstract
Our research area tackles the improvement of private data security using our proposed Steganographic method called DSoBMP-I (Distributed Steganography over BMP faze I) to improve the issues of low capacity, high detectability and distortion. The methodology consists of a new distributed steganographic approach to minimise the main weaknesses of today’s methods, including Discrete Cosine Transform, where the capacity, detectability and distortion needs an upgrade to accommodate securer steganography for our data protection. The proposed prototype approach that evolved after a few experiments using our distributed steganographic method, where secrete data is secure into a set of BMP files (as it is proven more reliable), originates from a raw file that is not necessarily a BMP at the start. After applying a layer of encryption for extra security using two different methods such as RC4 & RSA, comparing the two encryption techniques for its agility and extra security to address the issue of low capacity and better security using the DSoBMP-I method, all deriving from the supplied image. The overall achievement was improved capacity that doubles as the set of BMP images increases, less distortion and detectability as secrete data stays among different files. Keywords BMP .

1 Introduction Steganography is the act of hiding information in order to protect media database systems, digital content access control, data alteration protection, confidential communication and secret storage within the text, video, audio and image files. Steganography consists of hiding some content inside another while steganalysis is the process of identifyingSteganographyy itself. It

is important to note that steganalysis does not reveal the hidden message identified [14]. In order to uncover the secret message, using Cryptography as the method of breaking mathematical algorithms within secret communications. This study aimed to improve the security of Steganography techniques by examining and combining current methodologies to extend them to a novel approach to protect sensitive data. The inspiration comes from vulnerabilities of different methods such as Discrete Cosine Transform identified with low capacity, exposed to distortion and detectability issues [2] hence improvements became necessary to address and have been extended to all other current techniques. The research motivation is to tackle current vulnerabilities of Steganography algorithms and use the improved technique to protect data suc
