Abstract:
In recent years, Camera Smart phone has become a popular consumer electronics product. Young people like to use that to record their daily lives, moreover, they will share these photos and information to others. However, the photos may be used without consent after they are uploaded to Internet. To avoid this problem, one can embed visible and invisible watermarks into images. However, an additional process for embedding watermarks should be performed before an image is uploaded. When the number of photos is large, the process for embedding watermarks will bother the user. Thus, in this paper, we propose a copyright embedding system for Android platform. Using this system, pre-specified copyright information is automatically embedded into pictures with digital watermark technology when these pictures are taken. In addition, original images (i.e., images without watermarks) can be preserved selectively. This system has following features: (1) computational complexity of watermark embedding process is possibly reduced for handheld mobile system;(2) the watermark can be extracted without the use of the original image, (3) the watermark embedded into an image would not be removed by commonly used image processing operations, (4) embedding copyright information, resizing the images, and uploading images to Internet are automatically performed without manual intervention. Therefore, this system is very suitable for the protection of the photographs taken by Android phones to prevent piratical behaviors.
