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.

Should we care for Security and Privacy?
Would you leave your wallet on display, unattended in a public bar?
Personal Data is more important than this….
It may contain both financial as well as private life information!!!
▪ Data Security and Privacy are of outmost importance!

How can we ensure Security, Privacy and Trust
for an Individual?
▪ Assets need to be collected by the Individual
▪ Data need to be stored at the side of the
individual
▪ The individual should choose:
▪ When to share
▪ What to share (data/analytics/….)
▪ How to share (anonymous/encrypted/etc….)
▪ With whom to share
▪ Under which conditions to share
▪ The Individual should be aware of his risk
exposure
▪ The Individual should trust the platform and be
trusted by the platform!
