2. Trustworthy Computing Category of concept: Age Verification / Digital Identity Launch Status: Nether launched nor part of an existing product Concept: Reusing offline trust in online contexts Catalyze changes for creation of improved online trust, including optional Digital Playgrounds that enjoy similar levels of safety to their offline counterparts Use interoperable Information Cards as ‘keys’ to enabling such safer Digital Playgrounds Basis for discussion; not a completed “solution” ISTTF Presentation 9/23/2008

3. Trustworthy Computing Enabling such optional digital playgrounds first requires addressing two key items: 1. How to catalyze market-driven adoption of in-person proofing & Information Cards 2. Addressing non-technical policy issues including: Privacy: Architecting the system such that it does not create new privacy risks Security: How best to keep digital identities secure once they have been distributed; Determining whether a system like this strikes the right balance between risk and usefulness Education: Teaching children and parents about the importance of keeping their digital identity safe Identity Issuance Policies: Agreement on the criteria for in-person proofing events and the subsequent management of digital identity cards Resourcing / Indemnity: Providing institutions with the resources and indemnity needed for securely issuing and managing digital identity cards Critical Mass: What incentives would be needed for children to use such experiences? Moderation: What kind of moderating is appropriate? Who should moderate?
