The proposed authentication process is performed by a portable personal-usage authentication device, an access-control module for the portable personal-usage authentication device, and a player integrating the access control module. The portable personal-usage authentication device plays a role of secure storage in which domain authentication information is securely stored, while the access-control module is in charge of accessing the authentication information and, consequently, acquiring a decryption key. The player decrypts the broadcast programs in real time and processes the decrypted media streams. In this Paper, we describe the structure and procedure of the proposed model, and verify its feasibility by i...

We focus on the search robustness by minimizing the influence of photographing conditions such as changes in the illumination intensity. For an efficient search and precise detection, as well as robustness, we use a two-step comparison method based on indexing features and a binary map based on luminance and chrominance difference with the adjacent blocks. We also evaluate the proposed algorithm by comparing with the existing algorithms, and we show the content retrieval system that we've implemented using the proposed algorithm.

Usually, watermark is embedded with the same embedding strength regardless of local properties of the cover image, so the visible artifacts are taken placed at flat regions. A watermark is embedded into the perceptually significant coefficients (PSCs) of each subband using

In this paper, a new approach to implement a system for terrestial DTV broadcast program protection based on program protection information(PPI) is proposed. In our approach, the broadcast program is recorded with encryption according to redistribution condition of the PPI and packaged into a file with key information and PPI together. And we also define a set of domain protocol for supporting user fair-use of broadcast program. In the proposed system, copy control can also be provided by process of home domain management. Implementation results show that our system can protect broadcast programs with efficiency and can support conditional distribution within home domain in order to satisfy user fair-use.
