Chaotic signals are widely exploited for secure communication. Two secure image communication schemes based on Chebyshev map chaotic sequences are proposed. In the first scheme, the synchronization carrier signals can be retrieved directly from the received signals, and in the second scheme, the excellent correlation property of chaotic sequences is employed to realize secure communication. The results obtained by computer simulation indicate that the transmitted source image can be correctly and reliably recovered using each proposed scheme, even under the situations of a noisy channel. In addition, both schemes possess higher security and can be implemented easily. Lastly, the quality of the recovered image is discussed through calculating the bit-error rate, and the approximate relationship function is also obtained.
