Hi All,

The ICTD Conference <https://ictd2016.info/> is coming up and for the next
two weeks we'll have papers from UW presented at the Change seminar.
Please join us to hear about the great work happening on campus and give
feed back to the authors.

*When:* Tuesday,  May 25, 2016 at 12pm

*Where: *The Allen Center, CSE 203


*Computer Security for Data Collection Technologies*
*Camille Cobb, Samuel Sudar, Nicholas Reiter, Richard Anderson, Franziska
Roesner, Tadayoshi Kohno *

Many organizations in the developing world (e.g., NGOs), include digital
data collection in their workflow. Data collected can include information
that may be considered sensitive, such as medical or socioeconomic data,
and which could be affected by computer security attacks or unintentional
mishandling. This work, a collaboration between computer security and ICTD
researchers, explores security and privacy attitudes, practices, and needs
within organizations that use Open Data Kit (ODK), a prominent digital data
collection platform. We conduct a detailed threat modeling exercise to
inform our view on potential security threats, and then conduct and analyze
a survey and interviews with technology experts in these organizations to
ground this analysis in real deployment experiences. We then reflect upon
our results, drawing lessons for both organizations collecting data and for
tool developers.

*The Premise of Local Information: Building Reliable Economic Indicators
from a Decentralized Network of Contributors*
*Josh Blumenstock, Niall Keleher, and Joseph Reisinger*

This paper describes the design and implementation of Premise, a
mobile-phone based platform for gathering reliable, quantitative data
through on-the-ground networks of local contributors. Founded in 2012 and
currently operating in 34 countries, Premise provides small incentives to
ordinary citizens to collect high-quality data, and develops statistical
algorithms to aggregate millions of individual contributions into reliable
economic indicators. Our focus is on the deployment and scale-up of
Premise's operations in Nigeria and Liberia, two contexts that highlight
the diverse challenges involved in launching a crowd-based data collection
platform, ranging from the recruitment and retention of motivated
contributors, to the automatic detection of statistically aberrant data.
The goals of this paper are thus twofold: first, to provide transparency
into the operations of a new platform of growing prominence in the
development community; and second, to highlight key lessons learned that
can inform future design and deployment of novel methods for data
collection and synthesis in developing economies.
