Image Type

The healthcare industry has been facing a lot of challenges in securing electronic health records (EHR). Medical images have found a noteworthy position for diagnosis leading to therapeutic requirements. Millions of medical images of various modalities are generally safeguarded through software-based encryption. DICOM format is a widely used medical image type. In this chapter, DICOM image encryption implemented on cyclone FPGA and ARM microcontroller platforms is discussed. The methodology includes logistic map, DNA coding, and LFSR towards a balanced confusion – diffusion processes for encrypting 8-bit depth 256 × 256 resolution of DICOM images. For FPGA realization of this algorithm, the concurrency feature has been utilized by simultaneous processing of 128 × 128 pixel blocks which yielded a throughput of 79.4375 Mbps. Noticeably, the ARM controller which replicated this approach through sequential embedded “C” code took 1248 bytes in flash code memory and Cyclone IV FPGA consumed 21,870 logic elements for implementing the proposed encryption scheme with 50 MHz operating clock.

Security Issues

Telemedicine is defined as the means of providing healthcare for people from a distance by the use of telecommunication and information technology. This technology is mainly useful in overcoming the obstacles of distance and provide enhancement in the access of medical services that would not be easily available in different rural areas. Telemedicine security includes issues such as confidentiality, integrity, and authentication that are also present in other systems involving information and data. Maintaining integrity of data stored and used is a huge problem for medical applications because it contains more sensitive medical records of patients which can cause severe ill effects on slight modification. In order to resolve the confidentiality and integrity issues of telemedicine applications, medical image encryption and watermarking comes into play. The security issues in telemedicine applications is to be given higher importance and thus choosing a reliable and effective approach or framework is more essential.
