- Abstract
We developed a secure communication method using a discrete wavelet transform. Two users must each have a copy of the same piece of music to be able to communicate with each other. The message receiver can produce audio data similar to the sending user's speech by using our previously proposed method and the given recording of music. To improve the accuracy of speaker authentication, the quantization level for the scaling coefficients is increased. Furthermore, the amount of data sent to the message receiver can be remarkably reduced by exploiting the characteristics of this data.
