Digital Identity Scotland – Standards and Roadmap

Digital Identity Scotland is the program to define and deliver the Digital Identity section of the overall Scottish Government digital strategy.

Digital Identity Scotland is the program to define and deliver the Digital Identity section of the overall Scottish Government digital strategy.

There are a number of component teams and projects, including a Programme Board, Expert Group, a national stakeholder group.

As their recent blog explains their next steps include a prototype to test the design and technologies that would support an attribute service. The presentation from the session is available here.

As recently expressed by Cabinet Secretary Mike Russell at the launch of the Open Government Action Plan in January 2019:

“We are proactively publishing more information than ever before, and taking an open approach in our policy-making, particularly with the Digital Identity Scotland team, developing a common approach to how people demonstrate their identity for accessing public services online. Why do I use that example? Because it’s a key example of making sure the digital age serves the needs of a modern democracy.”

Program Board Papers

The main documents underpinning the work are listed here.

  1. Product Vision The Communications Update details the Product Vision and User Engagement plan. The User Research Update Document reports on the user research undertaken.
  2. Progress updates The Programme Plan – Update document describes the project and delivery strategy, organized into a first Discovery and Pre-Alpha stages of development, with their current position being Alpha stage.
  3. The Alpha Update Report describes this early prototype work, which is to provide a technical prototype for the creation and re-use of digital identities for access to Child DLA and the Single Person Council Tax Discount.
  4. Specifications – The Service Description for Relying Parties details the main operating and technical model for the Identity Service.

On Jul 3rd 2019 the team issued an OIX white paper, which provides a snapshot of all of these developments, within a context of adopting OIX standards.

Scottish Attribute Provider Service

The feature video introduces the Scottish Government’s plan to build and implement SAPS – The Scottish Attribute Provider Service, which:

“Will improve citizen’s access to public services, by providing them safe and easy ways to prove their identity, or attributes thereof, which are relevant to eligibility for the service.”

Key design principles include user-centric principles of only allowing the sharing of data between services with the active consent of the citizen, no data will be shared for commercial purposes nor will data be stored in a centralized database, ensuring that a citizen’s data remains under their own control, so they can store and consent to share their data with public sector organizations where needed.

Verified Attributes is data about a citizen that has been proven by a trusted public sector organization, that can be reused to save the user time and effort, and reduce bureaucracy costs for the government.

SAPS 1.0 – 4.0

An implementation roadmap is planned across four main phases:

  • 1.0 – Q4 2020: User will be provided a digital sign on for services, so that the user can save and resume online workflow processes.
  • 2.0 –  Q2 2021: User can save Verified Attributes for future use.
  • 3.0 – Q1 2022: Identities can be verified by trusted parties.
  • 4.0 – Q3 2023: An easier user journey, reducing data input requirements and removing dependence on third party identity providers.

User-Centred Design

From 11:20 they describe the methodology they’ve applied to ensure user needs are at the centre of the service design. They’ve set out to create an adaptable design that can cater for the full spectrum of different user scenarios, such as an Older Adult, a Parent and a Young Scot Card Holder.

These have been organized these into five main themes:

  1. Multiple user groups – Services that support the individual and the organization.
  2. Clearly add value – Communicate the benefits of the program.
  3. Ease of integration – Utilize current solutions and tie in with the existing user journeys.
  4. Accessibility – The solution needs to work well for every one.
  5. Future proof – The solution needs to be forward looking and enable public sector innovation.

High Level Solution

From 14:30 they share their high level design for the SAPS system, emphasizing the point it is an evolving design and they welcome feedback.

This will function as a closed ecosystem for public service providers, where they can make use of shared verified attributes to reduce friction when accessing digital services. The user will own and control their attributes, and be provided a single sign-on, giving access to a secure place for storing their attributes, an encrypted store where they can authorize their consents.

The three core building blocks of SAPS are The Credential Provider, the Attribute Store and Broker. The user will have a strong authentication credential from the outset without providing their identity, a credential that complies with GPG-44.

SAPS Relying Parties will offer users the ability to store and control their credentials in the Attribute Store, provided free of charge, and is controlled by the user – Only the owner will be able to view and decrypt the content. Attribute Store capability will include the ability to create and sign derived attributes.

The Broker will enable a low cost approach to integration, and will manage protocol flows and session state, supporting SSO across credential providers, as well as orchestrating calls to the Attribute Store.

Other functions will include consent management, derived attributes, standard metadata, delegation and attestation.

Procurement

At 29:50 they outline the procurement process for building SAPS. Their expectation is they will contract a capable development partner who can to plan, select and integrate the different functional components.
