| Abstract(in English) | A Method is described for embedding textual document into multimedia data, such as images, audios, videos, and others. Embedding text data into multimedia data includes the process in which textual document is converted into an image file, called a cipher image, whose values consists of '0' and '255' in color spectrum, the process in which multiple copies of the cipher image are generated to reduce error rate in recovering text message, the process in which the cipher image is mapped into frequency domain using Discrete Cosine Transform(DCT), the process in which the original image or audio is mapped into time-frequency domain using Wavelet Transform(WT), and the process in which coefficients of DCT and WT are integrated after modulation and addition. Extraction of the text message goes through the process in reversal order. The test result indicates that current approach is very promising. The correlation index between original text data and extracted text data is 0.998, which is and indication of exact recovery document. |
