Abstract

In Medical imaging system, the patient’s information plays an important role for tele-diagnosis, tele-health and tele-surgery. Medical image communication has become popular in public networks with the enormous growth in Internet technologies. Medical image verification is vital to ensure the privacy of the patient’s information. The conventional cryptography framework encrypts the secret medical information in a more complex, time-consuming and tedious process. A novel scheme called a Verifiable Secret Image Sharing (VSIS) scheme is proposed which is suitable for medical color image communications. The proposed method converts the medical color image into semantic image by using Dynamic Error Reduction (DER) technique for reducing the encoding complexity. The semantic image is encrypted into n shares and hidden into the cover images called stego-shares, to avoid malicious attacks. In the revealing side, the secret image is reconstructed using the shares, having no correlation with cover images. Based on the extracted token image in the revealing phase, the proposed VSIS scheme provides a good solution for improving the reliability, by the verification of collected shares and thereby identifying the cheating party. The experiment ensures the security, reliability and quality of the proposed scheme.
