505			_aAbstract Security is definitely essential to everyone. Nowadays, different data, information or documents are being sent everywhere. Through time, different techniques in securing private data have been used such as encryption, having password and Steganography. Steganography is about hiding a secret message within an ordinary medium and the extraction of it at its destination. Steganography has 3 types. The Text Steganography which hides the message inside a text, Audio Steganography which hides the message inside an audio file and Image Steganography which hides the message inside an image. This study is focused on the Image Steganography and based on the study “An Enhancement of Steganography Algorithm to hide Secret Message inside an Image” by Kenneth M. Carolino and Robin V. Sombilon (2016). The former researchers noted that the study is open for enhancement. By simulating the algorithm and analyzing the last researcher’s recommendation, we found several problems on the existing algorithm. First, some of the important ASCII Characters are not recognized by the algorithm. The next one is other languages with different character structure were not accepted by the algorithm so it turns out that the encrypted message does not decrypts the whole text message. Lastly, the algorithm fails to append another message in a single image. By the given problem, the aim of the further enhanced algorithm of this study is to decrypt and maintain the whole text being encrypted inside the image, to allow the user to input another character structure aside from ASCII and to allow the user to append messages into an existing encrypted message inside a single image.
