Hypermedia Applications With Transcoding Robust Data Embedding Method

This paper introduces a robust data embedding method under transcoding and presents several possible hypermedia applications based on the data embedding method. When a JPEG image is transmitted or uploaded through instant messaging services (IMS) or social networks services (SNS), transcoding is normally applied to the image. With transcoding, all metadata in the image is removed and sometimes pixel data itself can be modified. The data embedding method in this paper can be robust under transcoding of some IMS and SNS. Additionally, this paper introduces three applications, which are able to be operated on IMS and SNS, with the data embedding method on the JPEG image file; Image Scramble, Photo Message, and Audible Message.
