Security in big data of medical records

This research talk presents some of our results obtained in our efforts to protect the transmission of and access to the patient medical records. The algorithms developed in our group will be applied to medical records consisting of images, texts and voice files. In our earlier work on Mobile Health Information Systems and Services (MHISS) we have developed a Tele Nurse for intelligent Emergency Medicine usage in rural areas and COW (Care on Wheels) for rural diagnostics, monitoring and testing of high blood pressure, kidney dialysis, gynecological care and monitoring as well as establishing the first pediatric dossiers of the children for their vaccination and inoculation records. All this requires secure medical data transmission and sharing over distance and on line. This work presents a new method that combines image cryptography, data hiding and Steganography technique for denoised and safe image transmission purpose. In This method we encrypt the original image with stream cipher algorithm then embed the encrypted image with patient information by using lossless data embedding technique with data hiding key after that for more security. We apply steganography in embedded image with the private key. In receiver side when the message is arrived then we apply the inverse methods in reverse order to get the original image and patient information and to remove noise we extract the image before the decryption of message. We have applied and showed the results of our method to medical images.
