Maintaining Confidentiality and Integrity of Data and Preventing Unauthorized Access to DICOM Medical Images

With the development of telecommunication and communication technologies, especially wireless communications, information cryptography is one of the communication necessities. Today, cryptographic algorithms are used to increase security and prevent DICOM medical images from unauthorized access. It should be noted that changes in DICOM medical images will cause the doctor to misdiagnose the patient's treatment process. In this paper, a type of hybrid cryptographic algorithms is designed. In the proposed algorithm, DNA encryption algorithm is used to encrypt DICOM images and patient biometric information such as fingerprint or iris image is used to make digital signature and validate DICOM medical images. The designed encryption algorithm is resistant to brute force attacks and the entropy of the encrypted DICOM images is above 7.99.
