Abstract : This work presents a new method that combines image encryption and watermarking technique for safe transmission purpose. This method is based on the combination of public-private keys and secret key ciphering, and watermarking. The encryption algorithm with secret key is applied to the image. We encrypt the secret key with an encryption method based on public-private keys. Then, this secret key is embedded in the encrypted image. We apply and show the results of our method to medical images.
