Topic

Unified Information Hiding – the marriage of two fields

Abtract

The term “information hiding” can be perceived in two ways: to insert information into a content such as image (watermarking), or to mask the semantic of the information (encryption). Traditionally, these fields are explored independently. However, the availability of contents in large number and the computational power to manipulate them leads to a growing interest in integrating the features from both fields to manage and handle the contents more efficiently. In this talk, the motivations behind unifying information hiding are first presented in the context of image. Second, a framework is introduced to capture four different approaches in achieving the unification of information hiding. An example of each unification approach is then presented. Some additional properties of unified information hiding are detailed, followed by the limitation of the current state-of-the-art techniques as well as possible future research directions.
