“…However, the lack or inefficiency of information security planning makes it challenging to identify cybersecurity. This inefficiency also requires tools and methodologies to minimize cybersecurity consequences, which can cause large-scale damage to business sustainability [20].…”

“…This context requires preventive actions and security tools due to the sensitive data in healthcare systems such as digital signatures, professional credentials, financial data, patient diagnostic images, among others [19]. It is worth mentioning that this concern becomes even more complex when considering cyberattacks, especially due to the different interactions that occur on the Internet [20]. Furthermore, failure to comply with legal regulations may result in financial or criminal penalties [21,22].…”

Fuzzy Cognitive Scenario Mapping for Causes of Cybersecurity in Telehealth Services

Hospital organizations have adopted telehealth systems to expand their services to a portion of the Brazilian population with limited access to healthcare, mainly due to the geographical distance between their communities and hospitals. The importance and usage of those services have recently increased due to the COVID-19 state-level mobility interventions. These services work with sensitive and confidential data that contain medical records, medication prescriptions, and results of diagnostic processes. Understanding how cybersecurity impacts the development of telehealth strategies is crucial for creating secure systems for daily operations. In the application reported in this article, the Fuzzy Cognitive Maps (FCMs) translated the complexity of cybersecurity in telehealth services into intelligible and objective results in an expert-based cognitive map. The tool also allowed the construction of scenarios simulating the possible implications caused by common factors that affect telehealth systems. FCMs provide a better understanding of cybersecurity strategies using expert knowledge and scenario analysis, enabling the maturation of cybersecurity in telehealth services.

“…To address the issue, a number of methods have been proposed in the literature [19,20]: (1) increasing block dimension, (2) including block indices in the signature, (3) including image indices in the signature, and (4) breaking block-wise independency. In our work, in order for the scheme to resist VQ attacks we used a pseudo-random and different Key1 for each block.…”

This paper proposes a new reversible watermarking scheme for medical image authentication that makes use of hamming code as its authenticator and achieves reversibility through difference expansion (DE). The scheme has good tamper localization capability that permits us to pinpoint the location of changes in the watermarked image. Another important capability of the algorithm is that it can perfectly recover authentic blocks to their original state and hence eliminating the distortion that was introduced by watermark insertion algorithm. Experimental results show that the algorithm is successful at localizing the changes and can reach near perfect verification.

“…To preserve the confidentiality of medical data, cryptographic techniques can be adopted. In the history of medical data privacy, many cryptographic algorithms have been employed to prevent security breaches [4]. However, novel solutions are to be proposed to challenge the attacking scenarios.…”
