Ensuring Inclusive Security and Privacy for All Users: Challenges and Strategies

Core Concepts

Ensuring that security and privacy protections are inclusive and equitable for all users, regardless of their demographic background or environmental factors, is crucial for providing effective and accessible digital safety.

Abstract

The paper explores the challenges of ensuring security and privacy for users from diverse demographic backgrounds. It proposes a threat modeling approach to identify potential risks and countermeasures for product inclusion in security and privacy.
The key insights are:

Environmental factors like income disparity, location, device sharing, ML fairness, and security UI can impact a user's ability to achieve high levels of security and privacy. A global survey showed significant differences in security and privacy experiences across geographies.

Shared device usage is a major privacy concern, especially in certain cultures and developing countries. Android's multi-user feature can help, but more research is needed on secure compartmentalization solutions.

Physical device theft is more prevalent in developing countries, but biometric authentication adoption has helped mitigate this risk.

Accessibility services are widely used, but also abused by malware. Adoption varies greatly across geographies, requiring robust counter-abuse techniques.

Hardware security capabilities can vary across price points, impacting the security and privacy protections available to users. Transparency around these differences is needed.

ML fairness is critical for inclusive security and safety services like biometrics, malware detection, and presentation attack detection. Significant research gaps exist, especially for fingerprint systems and the impact of bias on malware infection rates.

Stalkerware poses unique challenges as it targets intimate partner violence, requiring specialized detection and mitigation approaches beyond traditional malware.

The paper highlights the need for a more inclusive approach to security and privacy and provides a framework for researchers and practitioners to consider when designing products and services for a diverse range of users.

Stats

"73% of smartphone users in India share their device with someone in their household."
"58% of smartphone users in Kenya and 56% in Nigeria have had a device stolen at some point."
"78% of smartphone users in Kenya and 77% in Nigeria make use of accessibility features, compared to 9% in Japan and 7% in Germany."
"60% of smartphone users in Kenya and 59% in Nigeria are 'very concerned' about the use of mobile data for OS updates, compared to 12% in Japan and 11% in Germany."

Quotes

"Suppose the ML models have issues with fairness or built-in biases against underrepresented groups. In that case, the models may underperform (e.g., a higher error rate for people with a darker skin tone) or even make incorrect decisions concerning those users."
"Abusers often even disclose the app's presence as part of the abuse cycle, and attempts to remove it can result in physical harm or even death."
