Issues And Trends In Healthcare Delivery System

Issues And Trends In Healthcare Delivery System

The issues and trends in healthcare delivery are constantly changing. The COVID-19 pandemic is one recent issue that wreaked havoc on healthcare systems, causing a shortage of healthcare workers, high demand for medicines and supplies, and increased medical expenditure due to a lack of insurance. Other issues include rising healthcare costs and care fragmentation.
Cost Containment
Payment for healthcare services has historically promoted adoption of costly and often unnecessary or inefficient...

Legal Guidelines for Documentation

The legal guidelines for nursing documentation are essential for ensuring accurate, professional, and ethical recording of patient care. The guidelines are discussed here:

Role-Based Identity

Role-Based Identity

Role-based identities are central to understanding how individuals navigate social environments by adopting distinct self-conceptions aligned with various societal roles. These identities are not fixed traits but are constructed through personal actions and the social feedback individuals receive in context-specific interactions. Each social role, such as student, teacher, or friend, carries a set of expectations and norms that influence how people think, feel, and behave within that...

Area of Science:

Computer Science
Cryptography
Information Security

Background:

Blockchain technology, crucial for finance and other sectors, relies heavily on robust security.
Current methods lack a systematic approach for managing private key security throughout its lifecycle.
Existing private key generation and encryption processes are often insecure, slow, or complex.

Purpose of the Study:

To propose a novel biometric-based private key encryption and management framework (BPKEM) for blockchain systems.
To address the challenges of private key lifecycle management and secure key generation.
To ensure compatibility with existing blockchain infrastructure.

Main Methods:

Development of a biometric-based stable key generation method using facial and fingerprint feature points.
Conversion of biometric feature points into stable and distinguishable descriptors.
Utilization of a reusable fuzzy extractor to create a secure and stable encryption key.

Main Results:

The proposed BPKEM framework effectively solves the private key lifecycle management problem.
The biometric-based key generation method provides a stable and distinguishable encryption key.
Experimental validation confirmed the correctness and efficiency of the new biometric-based blockchain encryption technique.

Conclusions:

The BPKEM framework offers a secure, efficient, and compatible solution for blockchain private key management.
Biometric data can be reliably used to generate stable and unique encryption keys for blockchain.
This approach enhances the overall security and dependability of blockchain systems.
