Secure Image Transmission with Efficient Resource Constraints Using Multiple Chaotic Systems

Electronic medical records, including medical images, clinical observations, medical histories and prescriptions are very confidential data. They are vulnerable to many security-related issues and they are not sent as it is through the network. In general, some cryptographic novel algorithms were being used prior to transmitting the data. Due to constraint of resources in some devices, complex encryption cannot be applied. Cloud (as a Third Party) is used to get the encryption done by outsourcing. The proposed method uses the same technique to accomplish the data transmission securely. Mixed encryption is used and encryption on both sides is done on medical images, which enhances image security. The sobel edge technique is used to extract ROI in medical images. To further reduce the algorithmic complexity, the upper four planes of the ROI part undergo shuffle and diffuse operation. The reformation of binary planes is performed using a chaotic system, followed by diffusion operation. Experiments including data loss attacks, differential attacks, statistical attacks, and brute force assaults show that the suggested encryption method performs better in terms of security. These findings demonstrate that compared to numerous chaotic encryption techniques put forth recently, the suggested method’s security is far better.
