The traffic of digital images has grown rapidly in the Internet. Security of image becomes important for many sectors mainly for medical applications. Nowadays, the transmission of medical images is a daily routine; especially over wireless (battlefields, traffic accidents, etc).This work presents a hybrid algorithm 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 have applied and showed the results of our method to medical images. We describe how it is possible to combine the techniques of encryption and watermarking in images.
Indeed, we constructed a new method with encryption algorithm with secret key for the image, with encryption based on public private key for the secret key and with watermarking method.
