We propose a secure image delivery scheme which can protect privacy of the secret region in sending image. In the scheme, the bits of the chosen secret region are first reversibly embedded into non-protection region. The secret region is then concealed or substituted with other meaningful content by our modified Poisson editing method, in which twice Laplacian operator is used to achieve better seamless effect. The protected image after editing can be delivered in channels securely. The attacker can't obtain the real content of the image without the keys. Experiments are carried out to show effectiveness and security of the scheme.
