Some Steganographic Methods for Delivering Secret Messages Using Cover Media

    Steganography is the science of secret message delivery using cover media. A digital image is a flexible medium used to carry a secret message because the slight modification of a cover image is hard to distinguish by human eyes. In this talk, I will introduce some novel steganographic methods based on different magic matrices. Among them, one method that uses a turtle shells magic matrix to guide cover pixels modification in order to imply secret data is the newest and the most interesting one. Experimental results demonstrated that this method, in comparison with previous related works, outperforms in both visual quality of the stego image and embedding capacity. In addition, I will introduce some future research issues that derived from the steganographic method based on the magic matrix.

In the meantime, he participates actively in international academic organizations and performs advisory work to government agencies and academic organizations.

Fuzzy Forecasting Based on High-Order Fuzzy Time Series and Genetic Algorithms

    In our daily life, we often use forecasting techniques to predict weather, earthquakes, stock, temperature, etc. Traditional forecasting methods cannot deal with forecasting problems whose historical data are linguistic values. In recent years, some researchers used fuzzy time series to handle forecasting problems. In this talk, we introduce two forecasting methods based on two factors high-order fuzzy time series and genetic algorithms. Firstly, we introduce a method to forecast the temperature and the TAIFEX (Taiwan Futures Exchange), based on the two-factors high-order fuzzy time series. Secondly, we introduce a method for temperature prediction and TAIFEX forecasting based on genetic algorithms and high-order fuzzy time series. Finally, we offer some research directions, which are worth pursuing for future research.
