Overview
• Data Data Everywhere….
• The Grid and its potential
• New confidentiality problems and opportunities
• Data Environment Analysis

Data Data Everywhere…
• Massive and exponential increase in data; Mackey and Purdam(2002); Purdam and Elliot(2002). – These studies have led to the setting up of the data monitoring service.
• Singer(1999) noted three behavioural tendencies:– Collect more information on each population unit
– Replace aggregate data with person specific databases
– Given the opportunity collect personal information
• Purdam and Elliot add:– Link data whenever you can

The Grid
• “Integrated infrastructure for high-performance distributed computation” Cannataro and Talia (2002)
– Grid middleware handles the technical issues communication, security, access/authentication etc… Cole et al (2002)
• Data grid
• Knowledge grid

A Blurring of Concepts
• The boundaries between data and processes become less distinct– Non-static datasets– One persons output is another person’s data

Combining and Enhancing Data
• Record linkage
• Data fusion
• Simulation
• Verification– Of data– Of output

Data Mining and the Grid
• Traditional Data Mining examines and identifies patterns on single (if massive) datasets.
• But Data Mining is really a method/ approach/ technology that has been waiting for the grid to happen. Multi dataset mining is now becoming a reality.

Agents
• AI concept
• Active programs capable of directed ‘intelligent’ search and manipulation. Web crawlers
• Building blocks of dynamic grid?

A Look Over the Horizon
• Absolute Seamlesness.– The ability to sit at a computer/terminal and
request the information one requires.• In natural language.
• Real-time dynamic modelling and simulation.

But…………
• Human issues• Closer to artificial consciousness
– Admit machines into our moral universe
• Technological Interdependence
• Confidentiality and privacy

Confidentiality issues and opportunities
• Data Linkage increases disclosure risk
BUT
• Indirect Data Access allows a new method of controlling disclosure and increase analytical power.

Data Environment Analysis
• Need to move with the technology from:– One shot analyses of individual datasets– Ongoing analyses of the data environment
• The question is Not how safe is my data but how disclosive is the data environment.
• A process of data monitoring is one aspect of this.

What sort of society?
• Informational Transparency?• Human- Computer Interdependence?• Individualism vs Collectivism
• A choice:• More legislation or less?• Personal information a commodity or public good
