Array of Things Governance & Privacy Policies

The Array of Things project and its researchers value privacy, transparency, accountability, and openness. We have worked with the city, the public, and legal experts to create governance and privacy policies that reflect these principles.

AoT privacy and governance policies were developed initially in the second half of 2015 and reviewed through a workshop including legal, academic, ethics, and privacy experts from the City of Chicago, the University of Chicago, Indiana University's Trusted CI (NSF Cybersecurity Center of Excellence) in early 2016. Throughout the first half of 2016 a series of public meetings were held to engage Chicago residents and community groups, and after this six-month period of public comment the policies were finalized and adopted. Since that time the project has regularly reviewed the policies and found them to be effective, thus they have remained unchanged. You can download the governance and privacy policies here.

We thank the public for their valuable input during the feedback period in the spring and summer of 2016. We have published responses to all questions received online and during public engagement meetings. You can also view a final Engagement Report from Smart Chicago, summarizing the public feedback period and lessons learned from these outreach efforts.


Privacy-preseving Image Processing

The AoT privacy policy details the AoT project emphasis on privacy, transparency, and openness. AoT devices save roughly one image on an hourly basis in order to create a library of such data types, necessary to "train" image processing software. This library is protected and only available to scientists who (a) propose to develop vision applications that comply with the AoT Privacy Policy, and (b) sign a data use agreement outlining restrictions on sharing any images that could potentially identify an individual.

With the exception of the training data, no images are saved. Rather, the nodes include computers that allow scientists to run image analysis software within the nodes themselves. Once images are processed by this software, they are deleted

All of the original AoT nodes were retired in place in September 2021, having exceeded their 2-year design lifetime in some cases having operated for over four years. Many of these will be replaced by more powerful devices currently being tested at Argonne National Laboratory. Roughly a dozen of these new nodes have been installed for testing in Chicago and dozens more have been deployed around the world. Prior to the original nodes being retired, the AoT team worked with Microsoft Research, JCDecaux, the Enironmental Law and Policy Center, and other partners to design and install a network of 115 air pollution sensors in summer 2021 on Chicago bus shelters as a field-test for experimental sensors. An interactive map of these devices can be accessed here or by scanning a QR code that is placed on each of the bus shelters hosting one of these nodes. The project team also worked with five community groups from Chicago's West and South sides to identify locations for the sensors.

Information regarding all vision applications under development or in use, including links to software used, is maintained at the SAGE Applications web page

AoT Annual Reports

At the close of each Federal fiscal year (September) the AoT project produced annual reports. These are available after a period of review by the National Science Foundation, thus will typically appear at the end of each calendar year. These parts are cumulative so that when read stand-alone they include both new activities and accomplishments and key accomplishments to date. As such, there is some duplication from year to year and the most recent reports are the most comprehensive.
