Steganography On Dithered Image Using Least Significant Bit(LSB)
Daftar Isi:
- In this century internet has become the most popular media, through internet we can share any kind of messages or information easly. Therefore Security and secrecy are important aspects required in the exchange of information or messages over the network / internet. Steganography is one of the most powerful techniques to conceal the existence of hidden secret data inside an image. The simplest approach to hiding data within an image file is called least significant bit (LSB) insertion. In this method, we can take the binary representation of the hidden data and overwrite the least significant bit of each byte within the image. If we are using 24-bit color, the amount of change will be minimal and indiscernible to the human eye. This project was made using the Java programming language and the algorithm using Floyd-Steinberg Dithering and Least Significant Bit (LSB). The image will be transformed become dithered image by using Floyd-Steinberg Dithering before the data is inserted. The image which is used to input is greyscale image with extention png,jpg and jpeg. The output will be png image. There will be also decode process in this program. It used to unhide the informations or messages that inserted to the image. The output of the decode process will be the messages which was inserted by the user.
