TL;DR: Digital customer management can be simplified when My Number Card-based status checks and latest basic information retrieval reduce manual updates, lower administrative burden, and improve data freshness in regulated customer workflows, according to Cybertrust Japan. The governance question is not whether identity data can be retrieved, but whether the surrounding lifecycle, consent, and update processes are designed to use it safely and consistently.
NHIMG editorial — based on content published by Cybertrust Japan: continuous customer management burden reduction using My Number Card status confirmation and latest basic information retrieval
By the numbers:
- 69% of organisations now have more machine identities than human ones.
- 96% of organisations store secrets outside of secrets managers in vulnerable locations including code, config files, and CI/CD tools.
- 71% of NHIs are not rotated within recommended time frames, increasing the risk of compromise over time.
Questions worth separating out
Q: How should organisations use trusted identity sources to reduce customer update burden?
A: Use the trusted source as a trigger for record refresh, not as a replacement for governance.
Q: Why do customer identity refresh workflows still create governance risk?
A: Because accurate identity proofing does not automatically keep every system aligned.
Q: What breaks when verification is disconnected from internal record updates?
A: The organisation ends up with a verified identity event that does not materially change the customer profile.
Practitioner guidance
- Map the customer identity refresh flow end to end Document where status confirmation starts, which internal systems receive updates, and which team owns reconciliation when the new information differs from existing records.
- Tie verification events to record-change controls Require each successful identity check to trigger a defined update path, including approval where needed, evidence capture, and downstream system synchronization.
- Separate identity proofing from record stewardship Assign one control owner for confirming identity and another for maintaining current customer attributes so accountability does not blur during routine updates.

Reduced administrative burden is only real when identity refresh becomes part of the lifecycle, not a side process. The article’s value is not the verification mechanism by itself, but the way it reduces recurring manual work in customer updates. That matters to IAM teams because identity data that cannot be refreshed cleanly becomes operational debt, especially in regulated or high-volume environments. The practitioner takeaway is that data freshness has to be designed into the identity lifecycle.
A few things that frame the scale:
- 69% of organisations now have more machine identities than human ones, according to The Critical Gaps in Machine Identity Management report.
- Only 5.7% of organisations have full visibility into their service accounts, according to the Ultimate Guide to NHIs , Key Challenges and Risks.
A question worth separating out:
Q: Who should be accountable for customer identity data freshness?
A: Accountability should sit with the team that owns the customer record lifecycle, not only with the team that performed the check. Verification establishes evidence, but record freshness depends on ownership, update rules, and reconciliation across systems. A clean split between proofing and stewardship prevents blame-shifting when data drifts.
