Medical images bear sensitive patient information, making their
transmission a security concern. The privacy and security of such graphical
representations and incidental patient information in transit via public networks must
be preserved. Medical images contain sensitive information, which sets them apart
from ordinary images. Medical images are more sensitive and contain crucial
information. This leads to a reliance on more secure techniques than conventional
methods like cryptography and data hiding, which normally take more time and
security. In this chapter, we propose implementing two innovative techniques to
enhance the security of medical data sharing: Prescription information concealed in
medical images and secure and share-prescription using a multi-secret sharing
blockchain. Prescription data hiding, on the other hand, refers to the encryption of
prescription details within normal-looking images like X-ray or MRI scans, among
others. Incorporating sensitive data into the images makes it difficult for unauthorized
persons to access them. Additionally, we build on the potential of using a blockchain,
an immovable and distributed database, to share crucial clinical information safely.
Medical data is kept through a blockchain database, which spreads the data around a
network. It becomes harder for attackers to tamper or alter the data using traditional
methods. Smart contracts also add security to data sharing by enabling data to be
available only to the relevant parties, which gives security an extra layer. As a novel
solution to solve the serious security issues of medical data sharing, the proposed
scheme involves prescription data hiding in medical images, multi-secret sharing-based
encryption, and the security properties of the blockchain. Our proposed techniques
ensure the privacy and integrity of patients' data when transmitting medical images.
