Ethical Standards I01:25

Ethical Standards I

1.3K
The American Nurses Association (ANA) created and implemented the first nationally accepted Code of Ethics for Nurses with Interpretive Statements. The Code of Ethics is a living document regularly updated by the ANA and establishes an ethical standard that is non-negotiable for nurses in all roles and settings.
The Code of Ethics provisions outline the nurse's duty to the patient, the healthcare team, the profession, and society. The Code's fundamental principles include advocacy,...

Healthcare Associated Infections II: Preventive Measures

3.4K
Essential infection prevention measures are based on the knowledge of the infection chain, the modes of transmission in healthcare settings, and the use of the best practices in all healthcare settings. Compulsory public reporting of healthcare-associated infection rates is needed to allow individuals and the community to make informed choices regarding selecting a healthcare facility.
The best practices for preventing healthcare-associated infections include hand hygiene, patient risk...

Standard precautions are the minimum infection control safeguards used while caring for all patients, irrespective of their disease condition. They help prevent the spread of common infectious microorganisms to healthcare workers, patients, and visitors in all healthcare settings.
Hand hygiene is the most crucial means to prevent the transmission of disease. Employers are legally required to provide their workers with personal protective equipment (PPE) to minimize exposure or contact with...

Area of Science:

  • Medical Imaging and Informatics
  • Cybersecurity in Healthcare
  • Cryptography and Data Security

Background:

  • The increasing use of telemedicine and electronic health (e-health) systems necessitates advanced methods for securing patient data.
  • Protecting patient privacy during the transmission of sensitive medical images, such as Computed Tomography (CT) scans for Coronavirus (COVID-19), is critical.

Purpose of the Study:

  • To develop and evaluate a novel encryption scheme for securing COVID-19 CT chest scan images for safe data transmission.
  • To enhance patient data privacy and ensure the integrity of medical information using a secure key-stream generator.

Main Methods:

  • A hashing version of the Blum Blum Shub (BBS) generator, named Hash-BBS (HBBS), was developed to create multiple secure key-streams.
  • The statistical properties of the generated key bit-strings were rigorously analyzed using the NIST-test-suite.
  • An encryption scheme was designed and applied to four COVID-19 CT images using the HBBS-generated key-streams.

Main Results:

  • The HBBS generator produced key bit-strings with excellent randomness and uniform distribution properties.
  • The proposed encryption scheme achieved a high degree of confidentiality and integrity for transmitting medical data.
  • Performance analysis indicated that the HBBS generator outperforms existing security methods in securing medical image transmission.

Conclusions:

  • The developed Hash-BBS generator provides a robust solution for encrypting COVID-19 CT images, ensuring secure data transmission.
  • The proposed method effectively addresses the security requirements for transmitting sensitive medical data in e-health environments.
