Robustness comparison study on watermarking techniques against compression attack

Digital watermarking technique is a way of protecting digital image from malicious attacks. Compression attack is one of the most common attacks for images uploaded into social media. Social media, such as Facebook and Twitter, implement compression method for all types of media, before it is successfully uploaded into their server. This is to reduce the network bandwidth and storage needed to store each media in their server. However, the implemented compression method tends to tarnish image properties from the image itself, which can be used to identify the image itself. This produces other problems, which are ownership and copyright issues. Digital watermark has been proposed in numerous researches, and this research is one of them, in preventing the stated problem. The chosen digital watermarking techniques must be able to withstand against compression attack done by social media. A comprehensive analysis towards the watermarking algorithms and watermarked images were done, by applying several designed experiments. Based on the results, it shows that both chosen watermarking techniques could not withstands against compression attack made by JPEG compression and social media compression. It indicates that watermarking technique was not a suitable method to be used in preserving the ownership and copyright of the image throughout social media
