Abstract
In order to enhance the performance of image hiding,an image hiding algorithm based on improved chaotic mapping is proposed.Firstly,the improved 3D-LSCM chaotic mapping is used and the initial values are utilized to generate a random sequence.Then,the measurement matrix constructed by the chaotic system together with the Hadamard matrix retains the properties of the Hadamard matrix and also has the control and synchronization of the chaotic system.The encryption algorithm utilizes the eigenvalues of the plaintext image in the encryption process,which has better security.In the experimental simulation,the NC values between the carrier image and the ciphertext image are all around 0.999 8,which is very close to 1,indicating that the final ciphertext image and the carrier image are very close to each other,thus proving the good imperceptibility of the proposed encryption scheme.Therefore,the attacker cannot discern any information about the plaintext image from the final ciphertext image.Simulation results and performance analysis show that the algorithm has high time efficiency,high robustness,large key space and high security.关键词
