Watermarking and Steganography

Watermarking and Steganography is one of the courses that will be given in the Bachelor of Telecommunication Engineering study program. What is Watermarking and Steganography? And what are the benefits of applying this concept? To get to know it better, please read the writing below.

Digital audio, video, images, and documents roam cyberspace. Unfortunately, along the way, someone can take this content for themselves. Anyone can download images, audio, or video from the web, copy it, edit it, send it, manipulate it, and so on. This allows violations of Intellectual Property Rights, such as: claiming someone else's work as one's own (ownership violation), duplicating and distributing digital works without the owner's permission (copyright violation), or altering content so that its authenticity is lost. The solution to this problem of digital content protection iscopyit, editing, sending, manipulating, and so on. This allows violations of Intellectual Property Rights, such as: claiming someone else's work as one's own (ownership violation), duplicating and distributing digital works without the owner's permission ( copyright), or altering content so that its authenticity is lost. The solution to this problem of digital content protection is Watermarking and Steganography.

Digital watermarking and steganography technologies greatly reduce these incidents by limiting or eliminating third parties' ability to decipher the content they have taken. Digital watermarking (embedding codes) and steganography (hiding information) techniques continue to develop. 

Bachelor of watermarking has advantages, including:

• Watermark insertion does not degrade quality and looks like the original. 
• Every copy of the multimedia data will carry the watermark within it. 
• The watermark cannot be erased or removed 
• The watermark can be detected/extracted again as proof of ownership and/or for detecting alterations copyright atau deteksi perubahan

Then, what is the difference between Steganografi and Watermarking? Steganography sends any secret message without arousing suspicion. This technique is secure, hard to detect, and can hold as many messages as possible (large capacity). Communication is point-to-point and the host medium means nothing (meaningless). Watermarking aims at protection copyright, proof of ownership, fingerprinting. This technique has robustness robustness and is hard to remove. Communication is one-to-many and it is the host medium that is protected; the watermark is not secret, and watermark capacity is not a priority. watermark tidak bersifat rahasia, dan tidak mementingkan kapasitas watermark.
