## Summary
Usable privacy and security is an academic discipline that studies how to make privacy and security systems easier for people to use. As a subfield of both human-computer interaction and privacy-enhancing technologies, its primary goal is to improve the effectiveness of security tools by focusing on their usability.

## Key Facts
- **Primary Goal:** To improve privacy and security by studying and enhancing usability.
- **Type:** It is classified as an academic discipline.
- **Parent Field:** It is a subfield of human–computer interaction (HCI).
- **Parent Field:** It is also a subfield of privacy-enhancing technologies (PETs).

## FAQs
### Q: What is the main goal of usable privacy and security?
A: The main goal is to improve privacy and security systems by making them more intuitive and easier for people to use correctly. It applies principles from human-computer interaction to solve security and privacy challenges that arise from complex or confusing designs.

### Q: What fields is usable privacy and security related to?
A: Usable privacy and security is an interdisciplinary field. It is formally considered a subclass of both human-computer interaction (HCI), an academic discipline, and privacy-enhancing technologies (PETs), which are methods for protecting user information.

### Q: Is usable privacy and security a specific technology?
A: No, it is an academic discipline and a field of study, not a single technology. This field's research and principles inform the design of various user-facing security tools and privacy-enhancing technologies to ensure they are effective in practice.

## Why It Matters
Usable privacy and security is significant because a security or privacy system is only effective if people can and will use it correctly. Many technically robust security tools fail in the real world because they are too complicated, confusing, or disruptive for the average user. This leads to users making mistakes, disabling security features, or avoiding the tools altogether, leaving them vulnerable to threats.

This field addresses the critical gap between the technical implementation of security and the real-world human behavior that determines its success. By focusing on user-centered design, it aims to create security systems that are intuitive and align with how people actually think and work. Ultimately, usable privacy and security helps ensure that the protections developed by experts are accessible and effective for everyone, strengthening security at its most common point of failure: the human user.

## Notable For
- **Interdisciplinary Nature:** It uniquely merges the user-centered design principles of human-computer interaction with the technical goals of computer security and privacy.
- **Human-Centric Approach:** Unlike traditional security fields that may focus solely on technical robustness, this discipline prioritizes the user's ability to understand, operate, and correctly manage security and privacy controls.
- **Focus on Practical Effectiveness:** It recognizes that a theoretically secure system is insecure in practice if it is too difficult for people to use, shifting the focus from purely technical solutions to holistic, user-aware systems.

## Body
### Definition and Scope
Usable privacy and security is an academic discipline focused on the intersection of usability, security, and privacy. The field studies how to design and build security and privacy systems that are not only technically sound but also easy for people to use effectively. Its scope includes everything from the design of password managers and encryption tools to the wording of privacy policies and security warnings.

### Academic Classification
The field is situated within two larger areas of study:
- **Human–Computer Interaction (HCI):** It is a subclass of HCI, drawing on its methods for understanding user behavior, designing user interfaces, and evaluating system usability.
- **Privacy-Enhancing Technologies (PETs):** It is also classified as a subclass of PETs, as its goal is to make these technologies more effective at protecting users' personally identifiable information (PII) by ensuring they are usable.
