TL;DR: Privacy by Design becoming ISO 31700 pushes privacy from policy into architecture, with 30 requirements spanning consumer control, lifecycle data management, governance, and breach mitigation, according to 1Kosmos. The real test is whether identity systems can enforce minimum collection, consent, and verification without storing unnecessary personal data.
Editorial analysis by NHI Mgmt Group, based on content published by 1Kosmos: “Architecture is Everything as 'Privacy by Design' Becomes an ISO Standard”.
By the numbers:
- ISO 31700 builds on 30 requirements that cover consumer control, lifecycle data management, corporate governance, and breach mitigation.
- The ISO network spans 167 national standards bodies.
- A negative privacy experience involving a data breach can erode brand trust by as much as 44%, according to Google and Ipsos research cited by 1Kosmos.
Key questions
Q: How should IAM teams design identity flows for Privacy by Design?
A: Start by reducing the identity journey to the minimum data needed for the transaction, then make consent, retention, and deletion rules part of the workflow itself.
Q: Why does ISO 31700 matter for consumer identity programmes?
A: Because it moves privacy from a policy statement into a standard that expects identity systems to enforce how data is collected, used, retained, and governed.
Q: What breaks when identity systems ask for more personal data than the transaction actually needs?
A: Overcollection breaks privacy first, but it also weakens security and trust.
Practitioner guidance
- Redesign identity flows for minimum collection Map each consumer identity journey and remove any personal data that is not strictly required for that specific transaction or verification step.
- Build retention into the identity workflow Define how long identity data is needed for each purpose, then align deletion and retention rules to those exact business purposes rather than broad platform defaults.
- Separate verification from data hoarding Use identity verification methods that confirm authenticity without forcing the organisation to persist large identity profiles on backend systems.
Bottom line: Privacy by Design has become an architecture requirement for identity programmes, not just a compliance principle.

ISO 31700 turns privacy into an identity architecture requirement, not a policy overlay. The standard matters because it forces privacy decisions into the design of authentication, data handling, and verification flows. That changes the governance problem from compliance language to runtime control, where the identity layer must enforce what can be collected, retained, and disclosed. Practitioners should treat this as an architecture decision first and a standards issue second.
A question worth separating out:
Q: How do privacy requirements change identity governance for banks and consumer services?
A: They shift governance from approving access to proving that data handling is minimised throughout the identity lifecycle. Banks and consumer services have to show that enrolment, verification, retention, and deletion all align with the purpose the user approved. That makes privacy evidence a core part of identity assurance.
