| Abstract | ||
| In this paper, the secret color image is embedded in speech signal using discrete wavelet transform (DWT) and wavelet packet transform (WPT). The information bits are hidden in the LSB (s) of discrete speech signal. Different number of parameters are changed such as level of wavelet transform (level 2 and 4), types of wavelet family (daubechies (Db4), coiflet (coif4) and symmlet (sym4)), the length of filter (Db2, Db6, Db8, Db10) and the number of bits in the LSB (1bit, 2bits and 3bits) where information to be hidden in it. The results show that WPT gives better performance than DWT | ||
