Abstract: Information security is becoming increasingly important in the modern networked age. Secure Image Transmission has the potential of being adopted for mass communication of sensitive data under the scrutiny of an adverse censoring authority. Images from various sources are often used and are transmitted through the internet for various purposes, such as confidential enterprise archives, document storage systems, medical imaging systems, and military image databases. These images may contain secret or confidential information since it should be protected from leakage during transmissions. A new type of computer art image called secret-fragment-visible mosaic image is proposed, which is created automatically by composing small fragments of a given image to become a target image in a mosaic form, achieving an effect of embedding the given image visibly but secretly in the resulting mosaic image. This effect of information hiding is useful for covert communication or secure keeping of secret images. receiver recover the secret image with a high precision. The root mean square error and peak signal to noise ratio are used as quality measures.
