Bibliographic Information

• Subject Area: Activism and Digital Security
• Keywords: BlackLivesMatter, Activism, Security, Privacy, BLM, Security Advice, Digital Activism, Privacy Concerns, Protest Safety, End-to-End Encryption

Research Background and Issues

• Identified Problems or Challenges:

  • Many participants in Black Lives Matter (BLM) protests are newcomers who face digital security and privacy risks, such as surveillance and threats from law enforcement or other organizations.
  • Although some guidelines provide digital security and privacy advice, the extent to which protesters are aware of, understand, and adopt these recommendations remains unclear.

• Significance:

  • In the face of privacy and security threats (e.g., government surveillance), understanding protesters' security needs and protective measures is a critical step in supporting activism and safeguarding participants.

• Research Motivation and Related Work:

  • Previous research on activism has largely focused on online activities on social media, with less attention paid to the use of digital technologies and associated threats in offline protests.
  • This study aims to fill this gap by analyzing the effectiveness of digital security advice in protecting protesters' privacy and security, providing evidence to improve safety guidelines.

Proposed Solution

• Proposed Approach:

  1. Collect and analyze widely distributed security guidelines from the spring 2020 BLM protests to extract and categorize digital security and privacy advice.
  2. Conduct an online survey to assess novice protesters' awareness, understanding, and adoption of these recommendations.

• Innovative Contributions:

  • Systematically analyzed 41 security guidelines and identified 13 key categories of digital security and privacy advice.
  • Combined survey data from 167 BLM protesters to evaluate the real-world impact of these recommendations, focusing on the specific needs of novice protesters.

• Implementation Steps and Key Techniques:

  1. Guideline Collection and Categorization:

     • Used keywords to search for publicly distributed guidelines on Twitter and Google.
     • Conducted cluster analysis on digital security and privacy-related advice (e.g., disabling biometric unlocking, using end-to-end encrypted (E2EE) applications).

  2. Survey Design:

     • Included questions on protesters' participation background, security concerns, and awareness and behavior regarding digital privacy advice.
     • Collected quantitative data (Likert scales) and qualitative data (open-ended responses) for regression analysis.

  3. Data Analysis:

     • Used quantitative analysis to reveal adoption rates of policy recommendations and related factors.
     • Applied coding methods to analyze protesters' understanding and interpretation of the advice, exploring the effectiveness of information dissemination.

Research Findings

• Specific Results:

  • Identified 13 categories of digital security advice mentioned in 41 guidelines:
    1. Disable biometric unlocking (mentioned in 28 guidelines)
    2. Set strong passwords
    3. Encrypt phones (mentioned in 9 guidelines)
    4. Disable notifications
    5. Recommend using end-to-end encrypted messaging apps (e.g., Signal) (mentioned in 27 guidelines)
    6. Use virtual private networks (VPNs) (mentioned in 4 guidelines)
    7. Limit mobile network transmissions (mentioned in 31 guidelines)
    8. Avoid carrying personal phones, among others.
  • Protesters were primarily concerned about issues such as personal privacy breaches (e.g., location tracking) and law enforcement accessing phone content or communication records.

• Advantages Compared to Existing Solutions:

  • Provided the first systematic analysis of the implementation of digital security advice during BLM protests.
  • Examined not only the content of the advice but also the motivations and barriers to protesters' adherence to the recommendations.

• Experimental or Evaluation Results:

  • While most protesters were familiar with advice such as "set strong passwords" and "avoid posting protest-related content on social media," awareness and implementation of more specific recommendations like "use E2EE apps" and "disable biometric unlocking" were significantly lower.
  • Protesters from different backgrounds exhibited varying levels of awareness of the advice; for instance, those with technical expertise or leadership roles in activism were more likely to understand and adopt these recommendations.

• Limitations and Future Directions:

  • Limitations:
    • The sample recruited via the Prolific platform may not fully represent the broader group of BLM protesters.
    • The survey relied on self-reported data, which may be subject to social desirability bias (i.e., participants' described behaviors may not align with actual practices).
  • Future Directions:
    • Improve user-centered security guideline design, such as adding sections on "reasons" and "how-to" instructions.
    • Explore more effective methods of disseminating advice, such as promoting security awareness through offline events and community training.
    • Investigate the privacy needs of protesters and broader social movement participants to design support tools that balance breadth and depth.
