FIR(Finite Impulse Response)滤波器:有限长单位冲激响应滤波器,是数字信号处理系统中最基本的元件,它可以在保证任意幅频特性的同时具有严格的线性相频特性,同时其单位抽样响应是有限长的,因而滤波器是稳定的系统。因此,FIR滤波器在通信、图像处理、模式识别等领域都有着广泛的应用。
(FIR (Finite Impulse Response) filters: finite impulse response filter unit, digital signal processing system is the most basic components, it can ensure that any increase in the frequency characteristics of both a strictly linear phase frequency characteristics, while its unit sample response is finite, and therefore the system filter is stable. Therefore, FIR filters in communications, image processing, pattern recognition and other fields have a wide range of applications.)

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.
