  1. An Economic Valuation Approach for (Privacy Enhancing) Identity Management ServicesSession: The economics of privacy FIA - Future Internet Assembly2011-05-18/19Budapest, Hungary Prof. Dr. Kai Rannenberg T-Mobile Chair ofMobile Business & Multilateral Security Goethe University Frankfurt, Germany www.m-chair.net

  2. Challenges to be addressed • Innovative business models for privacy • Pricing for/of privacy • Privacy as a service (product?) • An Economic valuation approach for privacy-enhancing Identity Management (IdM) services

  3. Economic valuation of privacy-enhancing IdM services • Motivation: • Valuation approach to overcome the shortcomings of decision making processes • Decision making processes of IdM service providers on market introductions of (or investments in) privacy-enhancing IdM services • Results: • Set of decision relevant economic consequences of adopting, mediating or providing privacy-enhancing IdM services • An indication to which extent privacy-enhancing IdM services are economically feasible • Testing by: • Real-life IdM infrastructure scenarios

  4. Process & Structure Model Process Model • Step 1: Description of the Baseline Option and feasible Delta Options • Step 2: Identification of each Stakeholder’s Costs and Benefits • Step 3: Selection of Key Costs and Benefits for each Stakeholder • Step 4: Clustering and Mapping of Key Costs and Benefits • Step 5: Assessment and Aggregation of clustered and mapped Key Costs and Benefits • Step 6: Visualisation of assessed and aggregatedKey Costs and Benefits Structure Model • Perspectives for each Stakeholder • Cost and Benefit Dimensions for private and institutional Perspectives • Costs and Benefits for each Dimension • Key Costs and Benefits • Cause Effect Chains for each Key Cost and Benefit • Weighting Factors for each Cause Effect Chain • Dimension Values • Decision Values

  11. Results of the Valuation - Summary Attribute Verification Service Scenario Authentication Service Scenario Privacy Policy Enforcement Service Scenario Dimension Values • Decision Values

  12. BenefitsSummary • Takes into account monetary as well as non-monetary costs and benefits • Presents decision-relevant information in a simple and structured way without over-challenging the decision maker • Integrates perspectives of different stakeholders, so that interdependencies can be evaluated • Enables a stronger focus on (and integration of) privacy-effects on consumers as an essential factor for economic success

  13. BenefitsProcessing of input • Considers • individual value perceptions of stakeholders to enable application field-specific valuations of IdM services • interdependencies between costs and benefits by using cause-effect chains • Enables the aggregation of costs and benefits to a one dimensional decision factor • Offers a • standardized and balanced evaluation approach by using predetermined holistic value-systems for stakeholders • standardized procedure for a repeatedly occurring decision problem for a better comparison beyond company and department boundaries

  14. BenefitsOrganisation of decision making • Leads to an improved decision making basis and to a higher transparency of the decision making process • Reduces intuitive (and consequently highly subjective) valuations, or rather, makes them at least more transparent for others • Structures complex decision processes and simplifies a separation into transparent sub-aspects • Enables a • division of work and thereby a specialization on sub-problems • parallelization of separate evaluation- and decision-steps • Provides a structured basis for discussions within a decision making group • Considers impacts on the decision maker’s individual goals and overall strategy

  15. 2011 StatementCloud ComputingSecurity and Privacy Issues Example (economic and business) concerns Typical issues with regard to the dependence on the cloud computing provider: • Risks for availability and business continuity; • Absence of contracts between the customer and provider; • Lack of “power-balancing” regulation, that exists for other utilities. • www.cepis.org • www.cepis.org/index.jsp?p=641&n=825f • www.cepis.org/media/CEPIS_Cloud_Computing_Security_v172.pdf

  16. Working Group meetingsJune 15, Espoo, Finland • Description of common characteristics of the identified most important services • Possible threats to user’s information privacy & security • What are the elements of trust, which are currently unsatisfied and what role can technology play • Technology requirements & roadmap • Law and policy driven design of technology enabling democratic structures, honours human rights and freedoms • Validation of important services in the light of upcoming EU legislation • Investigation of the economic and societal impact of new trustworthy ICT solutions • Definition of a R&D project portfolio with impact.

  17. Conclusion and Outlook • New ICT services are coming ever closer to people. • Privacy requires e.g. • Minimisation and decentralisation of data • Empowering users (“Multilateral Security”) on e.g. data flows • Privacy by Design • Related economic analysis and regulation • PrimeLife Summit Event, 2011-06-07 Lucernewww.sec2011.org • Kai.Rannenberg@m-chair.net • www.m-chair.net • www.primelife.eu • www.picos-project.eu • www.abc4trust.eu • www.fidis.net • www.prime-project.eu
