Talk 1: Addressing Security Challenges through Deep Inspection of Big Data on the Blockchain

With the rise of big data infrastructures, so have the challenges associated with tracking changes while maintaining data confidentiality, integrity, and availability of collected data. Maintaining a consistent security program across data collected can be increasing difficult while attesting for changes in the environment.

Securing Big Data has to meet the requirement of data at its provenance, security at and after each stage of transit, provision of secure data analytics, while assuring fine-grain controllability and observability.

To assure big data controllability, traceability, and observability for security, the principle is to create a `nervous system` for big data. This is akin to the bulk of the big data all tethered and controlled by lightweight, metadata-rich keys, sourced from a master trust anchor. Keys must come with an evidence of source of generation and mode of generation.

This talk aims to address those challenges while providing solutions backed by blockchain technologies.
