Application Of Daubechies Wavelet And Hamming Code In Digital Citra Watermarking)
The Need for Digital Watermarking in the Digital Age
The rapid development of digital technology and internet has provided convenience in accessing and distributing information in digital formats, such as text, image, audio, and video. However, this ease is often misused, ignoring copyright aspects, and causes illegal practices such as duplication and data distribution without permission. This raises concerns among copyright owners, including professional photographers and institutions such as museums. Therefore, a solution is needed to protect copyrights, one of which is through digital watermarking. Digital watermarking is a technique used to insert ownership information or other data into a digital image without damaging the quality of the image. The watermark that is inserted is designed in such a way that its existence cannot be detected by the human senses.
Understanding Daubechies Wavelet in Watermarking
The Daubechies Wavelet method is one of the very efficient transformation techniques for the Watermarking Citra. The use of wavelets in watermarking provides benefits in terms of high and low frequency representations. By using a wavelet transformation, digital images can be broken down into several frequency sub-bands, so that the watermark can be inserted at a certain frequency level without damaging important image details. This makes the watermark that is inserted more robust and less susceptible to disappearances and compression. The Daubechies Wavelet method has an advantage in terms of resistance to digital image manipulation, so that the watermark data that is inserted remains safe.
The Watermark Insertion Process using Daubechies Wavelet
The watermark insertion process using Daubechies Wavelet involves several steps. First, the original image will be transformed into the Wavelet domain. After that, the processed watermark will be inserted into the image's wavelet coefficient in certain sub-bands. This process is carried out with techniques that consider the strength of the wavelet coefficient to ensure that the watermark can survive the various image manipulation. The use of wavelet transformation in watermarking provides a more robust and less susceptible watermark.
The Role of Hamming Code in Ensuring Reliability
After the watermark is inserted, additional steps are needed to ensure the reliability of embedded information. This is where the Hamming Code (8.4) plays an important role. Hamming code is used to detect and correct errors in inserted data. By using this code, watermark information that is inserted becomes more resistant to undesirable changes that may occur during the storage or image transfer process. The Hamming Code works by adding a redundancy bit to the watermark data, so that if an error occurs in the data reading, the information can still be reconstructed correctly.
The Combination of Daubechies Wavelet and Hamming Code
The combination of Daubechies Wavelet and Hamming Code provides a sophisticated solution to protect copyright in digital images. The use of wavelet transformation methods and hamming codes not only guarantees image quality is maintained, but also ensures that the watermark that is inserted can survive from various forms of manipulation. This innovation has the potential to provide more protection against digital work, which in turn will provide a sense of security for copyright owners throughout the world.
Conclusion
The application of Daubechies Wavelet and Hamming Code in Digital Citra Watermarking offers a sophisticated solution to protect copyright in this digital era. The combination of wavelet transformation methods and hamming codes provides a robust and reliable watermarking system. This innovation has the potential to provide more protection against digital work, which in turn will provide a sense of security for copyright owners throughout the world.
Future Directions
The use of Daubechies Wavelet and Hamming Code in digital watermarking has opened up new possibilities for protecting copyright in digital images. Future research can focus on improving the efficiency and effectiveness of the watermarking system. Additionally, the use of other techniques such as machine learning and deep learning can be explored to improve the robustness and reliability of the watermarking system.
