Building the Community's Largest Labeled Mobile and Sensor Dataset

Ethical Mobile and Sensor Data

CrowdSignals.io will create the largest set of rich, longitudinal mobile and sensor data recorded from smartphones and smartwatches available to the community. The dataset will include geo-location, sensor, system and network logs, user interactions, social connections, and communications as well as user-provided ground truth labels and survey feedback. The data will be collected from a demographically diverse pool of Android users across the United States.

We will not profit from this dataset - all funds raised through crowdfunding will contribute directly to the data collection effort, this includes compensation for staff as well as for volunteers who consent to share their anonymized data. We will use best practices in recruiting, on-boarding, and managing volunteers. For volunteers, this means informed consent, the ability to opt-out at any time, and knowledge of who is using the data and for what purposes. For campaign sponsors, this means a legal agreement to commit to ethical use of the data as well as some transparency regarding how they will use of the data.

Rewards for Sponsors and Volunteers

CrowdSignals.io will generate many terabytes of mobile and sensor data recorded from smartphones and smartwatches over the duration of the data collection period. All sponsors will have access to the core, anonymized data a few weeks after the data is collected. Higher-level sponsors may additionally specify their own demographic surveys or ground truth labels to be used by volunteers recruited to the CrowdSignals.io data collection campaign. The dataset will be made available to non-sponsors for research purposes 12-18 months after the data is collected, at this time it will be free of charge but subject to the same constraints on ethical use.

For volunteers, there will be several educational and financial incentives. First, they will learn about the risks and benefits of sharing mobile data during informed consent. They will receive financial compensation along with access to insights and analytics about their own data after it is collected. Volunteers will also receive regular updates on how their data is enabling advances in a variety of fields from geography, to computer science, mobile health, social science, and many other areas.

How it Works

The Goal

Enable 1000's of Scientists and Developers Across a Variety of Fields


Our goal is to enable students, researchers, data scientists, and product groups across a variety of fields with the data they need to solve important societal problems - and to collect this data using best practices that inform, engage, and compensate data collection volunteers while respecting privacy.

CrowdSignals.io will use crowdfunding to finance the collection of a massive, shared dataset at a per sponsor cost that is orders of magnitude less than an in-house data collection. We aim to build a large enough group of sponsors to make the data accessible even to students who need data for a thesis or class project (e.g., $1-$2 per data collection volunteer, so a data from 100 volunteers could cost $100).


We've collected a large amount of very useful feedback from academia and industry on priorities for: (1) data collection parameters (e.g., data recorded, collection protocols, participant demographics, device categories), (2) ground truth event labels to collect from participants (e.g., activities, events, situations) and (3) anonymization techniques and data license terms that maximize the utility of the data while offering an adequate level of protection for data collection participants.

In March 2016 we're planning to launch a crowdfunding campaign for Phase 1 of CrowdSignals.io in which we will collect data from 30+ volunteers for 30 days.

"The ethical use and scaleable collection of data is an increasingly challenging problem faced in both academic and industrial research. Conflicting needs and interests are often masked or ignored as data is used, abused and repurposed without respect for the people who own it or created it. This mobile sensing approach in CrowdSignals.io is perfectly placed to address this challenge. Respect for the data matched with respect for the people, while leveraging the power of the crowd to create a global knowledge platform is the key to success here."
