Mobile Security Primer for Activists

Signal Logo

At MIT's Day of Action, Nathan Freitas of Guardian Project led a workshop on mobile security for activists, focusing on various secure messaging apps available today, touching on their benefits and risks for different kinds of activities and communities.

Common messaging apps (and their secure setting)

  • Conversations (default, can also interface with other secure XMPP apps like ChatSecure and Zom)
  • Facebook Messenger (secret conversations setting)
  • iMessage (only for messages to another iPhone/iMessage users, i.e. "blue" messages)
  • Signal (default)
  • WhatsApp (default)

All of these apps transfer messages over the internet via your data plan. SMS messages are never encrypted and can additionally be seen by your telephone company, which is particularly insecure because metadata from phone companies can be acquired without a warrant. Instead, internet-based messaging apps can be secured using "end to end" encryption with their secure settings. This means that messages are encrypted and then conveyed over encrypted connections (HTTPS/TLS) between phones and servers.

It's important to understand what each service knows about its users and what it stores. This may include:

  • When you are connected to the internet
  • Your phone number for user identity purposes (thus, they can look up your name at the phone company)
  • Your network of friends, IF you uploaded your contact book

Because of end to end encryption, these companies generally don't have access to your messages unless you are using them on an insecure setting like green messages on iMessage (actually sent by SMS) or non-secret Facebook Messengers messages. Because of this companies under subpoena can only provide metadata, not the messages themselves.

Is the Civic State of the Union strong, and if not how do we go about strengthening it?

Research Ethics in Social Computing: A Discussion

This is a liveblog of the town hall discussion "CSCW Research Ethics Town Hall: Working Towards Community Norms" at CSCW 2017.

Panelists from the SIGCHI Ethics Committee

The SIGCHI Ethics Committee is charged with helping facilitate community conversations—helping social norms emerge from the community. This should help refine ACM’s policies and procedures. The Committee does not make decisions about what is ethical. Bruckman also sits on ACM COPE which works on ACM’s Code of Conduct (which was written before the Web existed).

Bruckman and Feisler start the town hall off by reflecting on how traditional human subjects rules were written for medical research. This is often a poor fit for social science, internet environment, methods that involve stakeholders as full partners, and interventions in public places.

Common open questions in research ethics across computer science communities include how we develop ethical standards that work cross-nationally and cross-disciplinarily. Serious issues involve data privacy and legality with respect to “public” data and platform terms of service, and how to secure truly informed consent. The following are the questions and comments discussed during the town hall.

Lessons from Fighting Swiss Right-Wing Populism: Flavia Kleiner and Operation Libero

Flavia Kleiner and Operation Libero logo

In early 2016, Operation Libero, an anti-populist movement cofounded by history student Flavia Kleiner, 26, successfully defeated an anti-immigrant Swiss ballot initiative. The "enforcement" initiative, sponsored by the nationalist Swiss People’s Party (SVP), would have ordered the deportation of immigrants in Switzerland for any criminal offense, no matter how minor. Often, initiative sponsors like the SVP frame such issues in terms of Swiss values and innocuous outcomes for citizens to control the narrative and reduce the potential for negative response. In this case, the SVP initiative followed a long and bruising federal election, and their usual political opponents were exhausted and out of funds to fight the initiative. So Kleiner and friends built a grassroots movement and coalition for "No" on the enforcement initiative to re-frame the issue, reclaim Swiss values, and drive attention to the anti-immigrant initiative. The successful effort has since blossomed into a suite of campaigns under Operation Libero to oppose populist and illiberal rhetoric more broadly.
