SECURE TRANSMISSION OF MEDICAL IMAGES USING BLOCKCHAIN TECHNOLOGY

Medical images are crucial in the diagnosis and treatment of diseases.Nowadays, secure transmission of medical images is very essential.An effective technique for preventing unauthorized access to medical images is medical image encryption.This article highlights a cutting-edge strategy for employing blockchain technology to securely transmit medical data.In the first stage, the patient data and medical images are integrated during the embedding process by using watermarking.After embedding the patient information in the medical image the image encryption is used to encrypt the images.Multiple file formats are supported by this technique for making the system user-friendly and portable.In the second stage, the image's cryptographic pixel values are saved on the blockchain to guarantee the security and privacy.The blockchain's distributed ecosystem facilitates the development of a medical institution network for prompt diagnosis.
