Breaking Big Data Silos: Opportunities and Security Threats



Giovedi 28 Aprile 2016

Today, companies and government agencies alike have access to more customer information than ever before. Transactional data can provide deep insight into individual customers’ behavior, to be complemented with user profiles, website clickstreams, call center logs and emails, and external data coming from social media. Experience has shown that customer acquisition (attracting new customers), customer life-time value maximization (cross-selling and up-selling to existing customers) and churn prevention (preventing customers from switching to another provider) are expected to work best when tailored to individual customers’ needs. BDA also promises to find innovative ways to reduce risk., e.g. addressing fraud threats without antagonizing regular customers. The overall recipe advertised by vendors for enabling BDA-driven innovation is breaking down the IT “silos”, bringing data from different departments together into a common representation and a single source of knowledge. However, adopting a “silos-breaking” data fusion strategy can itself be a source of risk and regulatory compliance headaches. Pulling out and merging data from various sources for analytics may increase the numer of replicas of sensitive data items, and increase the likelihood of data leakages or inference attacks. Also, it may make it difficult to avoid violations of custody obligations and usage constraints on the original data. The talk will provide a threat/opportunity analysis of data preparation and fusion strategies, highlighting the research issues to be handled in order to enable a risk-aware approach to data-driven innovation.
