FILE ENCRYPTION AND HASH SYSTEM USING JAVA PROGRAMMING LANGUAGE FOR IMAGE STEGANOGRAPHY
Due to the rapid development and rapid popularization of the information technology, internet and digital media have become an important tool for military, commercial, individuals and many other organizations to obtain and transmit information. However, digital communication via the Internet is vulnerable to eavesdropping, malicious interference and other activities. As a result, data transmission protection and information security issues become a bottleneck than ever before. This paper presents file encryption and Hash system (Image Steganography) via Least Significant Bit (LSB) approachto increase the amount of text file the cover image can conceal. The software used consists of two sections: the Encode section (embedded text file by using an image as cover) and the Decode section (extract the embedded text from the cover image) which is implemented through NetBeans IDE using Java Programming Language.The different results obtained when the proposed device was tested revealed that it worked according to the design specifications.
