Privacy Value Networks
1. Privacy Value Networks Project

• St Andrews University
• University College London
• Consult Hyperion
• BT

2. Project Aims
• To account for value (and devalue) of data items
from the perspective of all stakeholders
• Company/government and customer/citizen
• Secondary users (e.g. other family members,
neighbours)
• To account for individual, commercial and
societal costs and benefits
• Immediate and long-term
• To model impact of data quality and transparency
3. Reality: Value and De-value
• Customers/citizens feel privacy is violated even
when data is handled in accordance with DPA
• Take action to protect themselves, e.g.
• Abandoning forms when phone number requested
• False DOB on social networking sites
• Decreasing data quality
• Discrepancy between customer/citizen and
“data shadow”
• Value networks – impact on 3rd parties?

• What information would allow ‘better’ decisions?
• How could existing information be better used to provide
services the users want?
• Values of personal information providers hold about customers
w.r.t.
• The customers
• The providers themselves
• Their competitors / other service providers
• Recruitment
• In talks with a high street bank
• Looking for wider range of service providers
10. Conclusions

processing and retention
• Applying DPA, and beyond
• Consider value and de-value for all stakeholders
• Wider and long-term impacts for value networks
• Tool for impact modelling
• Can be used to facilitate Privacy Impact Assessments
(PIA)
• Improved data quality will benefit all
stakeholders
