The BYTE project was funded by the European Commission to assist European science and industry in capturing the positive impacts and diminishing the negative impacts of big data collection and processing. BYTE moved beyond current practices to consider how big data will develop to the year 2020 using foresight tools to identify future practices, applications and positive and negative impacts. BYTE delivered a research and policy Roadmap to help Europe capture a greater share of the big data market by using big data responsibly.
