模拟一个城市的气温在15年内的变化情况，以及统计气温的各种变化走势和在一定时间段内气温的各种统计量。(Simulation of a city in 15 years the temperature changes, as well as statistical temperature changes trend and within a certain period of time the temperature of various statistics.)

This paper presents a novel algorithm of hiding secret messages by applying mathematical lemmas and information theory. The proposed algorithm can hide more information with acceptable embedded rate and achieves requirements of information hiding algorithm and simply information extracting. The main idea is applying modern algebra to solve the information hiding problem in multimedia. In order to prevent some attacks on stganography, hidden initial bits of image data pixels are chosen randomly. The extracted information are achieved without the reference of the original image and extracted keys. The experiment results show that our approach is effective and reliable.
