Conversion of bitmap text images for data hiding

In this paper, we propose the comparison of original text in the form of bitmap image and extracted image by using various fonts of text as a bitmap image. The purpose of data hiding is to embed relating textural description into an image. The textural description and original host image can be extracted and reconstructed from the stego-image in the data extraction process. However, the reconstructed host image will more or less be damaged or distorted by using traditional data hiding methods. The advantage of applying LSB data hiding is its simplicity in implementation and its robustness. However, it is not suitable for the data hiding of binary images because the original host image cannot be completely reconstructed due to the problem of information loss. Here we designed a program in Matlab using image processing toolbox which can encode the text images in a single color image. We can recover the image very easily.
