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.

Microbial Biosensors01:17

Microbial Biosensors

Microbial biosensors are analytical devices that utilize living microbes to detect specific substances through measurable signals. These devices consist of two main components: biosensing organisms and signal-transducing elements. Biosensing organisms, such as Escherichia coli or Saccharomyces cerevisiae, are typically housed in multiwell plates connected to transducers, enabling rapid, real-time detection of target analytes.Signal Generation MechanismWhen a target analyte—such as...
Automatic Processing and Automatic Social Behavior01:28

Automatic Processing and Automatic Social Behavior

Automatic processing refers to the cognitive operations that occur without conscious intent or awareness, playing a fundamental role in shaping social cognition and behavior. These processes enable individuals to navigate complex social environments efficiently by relying on mental shortcuts and pre-existing knowledge structures known as schemas. One of the most influential mechanisms underlying automatic processing is priming, which subtly activates mental representations through exposure to...

Area of Science:

  • Cybersecurity
  • Internet of Things (IoT)
  • Blockchain Technology

Background:

  • Sensor networks face significant security vulnerabilities, particularly with resource-constrained IoT devices.
  • Adversaries can exploit session spoofing to manipulate data fed into Artificial Intelligence (AI) systems, leading to data poisoning.
  • Existing solutions like Hardware Root-of-Trust (HRoT) using Physically Unclonable Functions (PUFs) are often too expensive for widespread sensor deployment.

Purpose of the Study:

  • To propose a novel security solution, Physical Cyber Authentication (PCA), for sensor networks.
  • To overcome the limitations of existing security measures for low-end and middle-end IoT devices.
  • To enhance the integrity of data used for AI learning in sensor networks.

Main Methods:

  • Anchoring Blockchain accounts (logical nodes) to the integrated circuit (IC) chip of individual sensors.
  • Utilizing Blockchain to manage sensor networks and ensure data integrity.
  • Establishing a seamless link between physical sensor nodes and their logical representations in a virtual network.

Main Results:

  • PCA effectively prevents session spoofing by linking logical nodes to physical sensor hardware.
  • The proposed method enhances data integrity, making AI learning more reliable.
  • It provides a scalable and cost-effective security solution for a large number of IoT devices.

Conclusions:

  • Physical Cyber Authentication (PCA) offers a robust solution to sensor network security challenges.
  • By leveraging Blockchain and IC chip anchoring, PCA secures data pipelines for AI.
  • This approach ensures the trustworthiness of AI models trained on sensor data, even in large-scale IoT deployments.
