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...

Plant Breeding and Biotechnology

Crop cultivation has a long history in human civilization, with records showing the cultivation of cereal plants beginning at around 8000 BC. This early plant breeding was developed primarily to provide a steady supply of food.

Area of Science:

  • Agricultural Technology
  • Computer Science
  • Cybersecurity

Background:

  • Precision agriculture requires secure data acquisition, authenticated device interactions, and transparent decision-making.
  • Existing systems face challenges in integrating Internet of Things (IoT), blockchain, and artificial intelligence (AI) for robust agricultural solutions.
  • Secure and automated agronomic decision-making is crucial for optimizing crop yields and resource management.

Purpose of the Study:

  • To present RiceBlock, a novel blockchain-IoT framework for secure data collection and automated agronomic decisions in precision rice farming.
  • To enhance data integrity, confidentiality, and device authentication in agricultural IoT systems.
  • To provide a scalable and privacy-preserving architecture for AI-driven agricultural intelligence.

Main Methods:

  • Implemented SHA-256 hashing and AES-256-GCM encryption for data integrity and confidentiality.
  • Utilized Ethereum digital signatures and timestamp verification for mutual authentication between sensor nodes, cluster heads, and user mobile devices.
  • Employed Solidity smart contracts under Proof-of-Authority (PoA) consensus for governing device identity, data provenance, and AI-driven decisions.

Main Results:

  • RiceBlock achieved a mean transaction latency of 5.73 seconds and a throughput of 22 transactions per second.
  • Demonstrated high authentication success rate (98.2%) with low false acceptance (1.8%) and equal error (2.1%) rates.
  • Confirmed decision accuracy with an F1-score of 0.93 and ROC-AUC of 0.96, showing resilience against replay and forgery attacks.

Conclusions:

  • RiceBlock effectively secures environmental data collection and automates agronomic decisions for precision rice farming.
  • The framework provides a scalable, privacy-preserving architecture, successfully bridging blockchain-based trust with AI-driven agricultural intelligence.
  • The system offers enhanced security and transparency, paving the way for more efficient and reliable precision agriculture.
