Working Group 1 - Use Cases

1. Statement of purpose

The Use Cases Working Group will define our digital life by identifying the services the industry finds the most potential. The identified services are turned into generic use cases describing the common characteristics of these services.

The possible threats to a user’s information security and privacy can be derived from the use cases (“user stories”). Once more use cases are identified by the Use Cases Working Group contributors, the Working Group will set priorities for different use cases, the top priority use cases setting the focus for the initiative.

2. Scope of the Working Group

The Use Cases Working Group will cover topics related to:

• Trust, information security, privacy, transparency, accountability and reputation

Trust is an essential pre-requisite for connecting people in effective personal and business transactions. It builds in our society on the rule of legislation and stable democratic institutions, as well as on elements like security, privacy, transparency, accountability and reputation. The Trust in Digital Life initiative aims to set out a vision for trustworthy solutions in the field of information and communications technology (ICT).

This is a broad concept, and the vision of the use cases working group is to focus the efforts of the Trust in Digital Life initiative to the areas the industry finds most potential.

3. Timeframe

The Use Cases Working Group is to carry out its work in a continuous mode.

4. Definition of the desired end result and any intermediate deliverables

By the end of December 2011, the Use Cases Working Group is to produce, on top of different use cases, a white paper for digital services as the end result of the WG work.

The Use Cases Working Group will produce intermediate deliverables leading up to its final deliverable(s), as follows:

• Use cases draft report by the end of every half a year for WG2 Requirements and Technology for defining the threat landscape and for WG3 Law and Technology for defining the legal aspects based on the user stories

5. Guidelines regarding composition

In line with the general aim for balance in the Trust in Digital Life initiative, the Use Cases Working Group should strive to have the following composition:

• One third solution providers;
• One third application customers, or service industries that will use the technologies; and
• One third academic researchers and others from non-profit organizations (e.g., consumer groups, civil and political rights advocates, etc.) whose work relates to the Objectives.

6. Methodology

The use cases will be defined according to the following principles:

• Identification of services

The services that can be considered to be the most popular by the consumers or are emerging services yet to become mainstream services should be selected as use cases. New services are suggested by the working group members and the management team can propose additional services for working group discussion. The more supporting companies a use case has, the more potential it can be considered.

• Grouping similar services together in order to identify the characteristics of these services

Digital services are diverse, but it is possible to group  services together by different characteristics. The working group needs to define these characteristics and concurrently define the vocabulary used in this initiative.

• Define a generic use case

After similar services are grouped together, common characteristics are analyzed and a generic use case to describe these associated services is identified. An example of a generic use case is an Internet bank that must have strong user authentication, secure authentication and strict digital asset protection.

• Identify requirements and use cases (“user stories”)

The Working Group 1 should document the user stories for identified use cases.

• Management board sets the priority of the use case

Once necessary, management board can set priorities for different use cases to be processed by the subsequent working groups.

• Maintain a library of use cases

The working group must maintain the defined use cases and associated priorities in a prudent manner.

• Pass the use case for WG2 and WG3 for further analysis

Once the use case has been defined, accepted and prioritized, the use case definition is passed for the subsequent working groups.

• Document the threat landscape for digital services

The final deliverable of Working Group 1 will be having whitepapers/ position papers per each identified use case.

7. Working Methods

For its working methods, this working group will follow the Consortium Agreement and the Policies and Procedures for the Trust in Digital Life initiative.
