Data Privacy, Security in personal data sharing

Big Data lay at the core of the strong data economy that is emerging in Europe. Although both large enterprises and SMEs acknowledge the potential of Big Data in disrupting the market and business models, this is not reflected in the growth of the data economy. The lack of trusted, secure, ethical-driven personal data platforms and privacy-aware analytics, hinders the growth of the data economy and creates concerns. The main considerations are related to the secure sharing of personal and proprietary/industrial data, and the definition of a fair remuneration mechanism that will be able to capture, produce, release and cash out the value of data, always for the benefit of all the involved stakeholders.

This webinar will focus on how such concerns that pertain to privacy, ethics and intellectual property rights can be tackled, by allowing individuals to take ownership and control of their data and share them at will, through flexible data sharing and fair compensation schemes with other entities (companies or not), as researched by the DataVaults project.

Vision ▪ FOR WHOM? DataVaults will enable a new mode of collaboration/business relationship between individuals and organizations that would like to manage/process the personal data of individuals ▪ WHY? Turn the personal data value chain into a multi-sided and multi-tier ecosystem governed by smart contracts to safeguard data ownership, privacy and usage and attribute value to all entities that generate value within this chain and especially data owners. DataVaults aims to deliver a framework and a platform that has personal data, coming from diverse sources in its centre and that defines secure, trusted and privacy preserving mechanisms allowing individuals to take ownership and control of their data and share them at will, through flexible data sharing and fair compensation schemes with other entities Target Users: Individuals – Data Providers – Data Seekers & Data Analysts 2
