Study on Steganography using LSB Method on Images
The most used media in today‟s world is image files. This is a web based user communication which allows the users to communicate with multiple media sources and build relationship networks. This media communication also permits open communication. This research paper defines the usage of image files in Steganography. Steganography is a tool for hiding information inside an image. For the addition of image or text, it utilizes the least bit of pixel units in an image file i.e Least Significant Bit (LSB). Steganography uses the debility of the human eye in looking at the image file, steganography also uses precise calculations in adding messages into the image file. Based on the binary of the ASCII code of the character the insertion is done. Research is also done on the comparison image file size to the information size that has been added. Hence, there is a prospect for further research for proficiencies of detection tools can be way developed with more features digital analysis.
