Summary
Smart cities collect vast personal data, risking privacy. This study introduces an infrastructure using attribute-based credentials and GDPR compliance for secure, user-controlled data management, ensuring privacy and unlinkability.
Area of Science:
- Computer Science
- Information Security
- Urban Studies
Background:
- Mobile devices fuel smart city growth, increasing personal data sharing.
- Inadequate data management poses significant security and privacy risks.
Purpose of the Study:
- To propose a smart city infrastructure for privacy-preserving identity management.
- To ensure GDPR compliance in smart city data handling.
- To enable user-centric control over personal data and consent.
Main Methods:
- Integration of a distributed privacy-preserving identity management solution using attribute-based credentials (p-ABC).
- Implementation of a user-centric Consent Manager.
- Adoption of a GDPR-based Access Control mechanism.
Main Results:
- The infrastructure supports specific data purposes, collection, access control, and user consent.
- Achieved selective and minimal disclosure of personal information.
- Ensured user unlinkability across service and identity providers.
Conclusions:
- The proposed smart city infrastructure is feasible and effective.
- Demonstrated successful integration and evaluation in a real-world smart city project (MiMurcia).
- The system enhances security, privacy, and GDPR compliance in smart cities.

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,...

Geographic Information Systems (GIS) rely on two core types of data: spatial data and attribute data.Spatial DataSpatial data defines the physical location of features within a coordinate system, typically expressed in terms of latitude and longitude. It provides precise positioning for elements like roads, rivers, or buildings.Attribute DataAttribute data complements spatial data by adding descriptive information about these features. For example, a road's spatial data includes its start and...

01:17Design Example: Analyzing Capacity Contours for Flood Risk Assessment
150
Flood risk assessment involves careful planning and analysis to ensure the safety of communities near water retention structures. Capacity contours are a vital tool in this process, as they illustrate the potential spread of water at specific levels in a given area. In the context of building a bund across a small valley, these contours play a critical role in evaluating the safety of nearby residential areas.In this example, the bund is intended to store stormwater in the valley. The engineers...

A schema is a mental construct consisting of a cluster or collection of related concepts (Bartlett, 1932). There are many different types of schemata, and they all have one thing in common: schemata are a method of organizing information that allows the brain to work more efficiently. When a schema is activated, the brain makes immediate assumptions about the person or object being observed.
