PbD | Privacy by Design

Privacy should answer where data came from, why it is used, which model receives it, who can access it, how long it is kept, and when it must be deleted or blocked.

03 / Privacy operating blueprint: subject, policy, execution, and evidence control chain
The six stages in the blueprint map one-to-one to the sections below: every node has an action, an owner, and an evidence output.
01

Data map

Know where data lives, who owns it, and how it is classified

Map business data, logs, backups, model context, and external connections before setting residency and ownership boundaries.

Execution steps

  1. 01

    Inventory data sources and outputs

  2. 02

    Classify sensitivity and data subject

  3. 03

    Record region, processor, recipient

  4. 04

    Build flow and ownership matrix

Acceptance evidenceData class and ownerResidency and processorInbound, outbound, backup paths

02

Purpose minimization

Take only what the task requires

Bind purpose, role, and object permissions into retrieval so model appetite never expands the data scope.

Execution steps

  1. 01

    Define purpose and legitimate scope

  2. 02

    Filter objects and fields

  3. 03

    Remove irrelevant content

  4. 04

    Record minimization rule

03

Context isolation

Do not mix context across tenants, projects, or roles

Retrieval, cache, session, and memory carry tenant and permission labels; cross-boundary reference requires explicit authorization and evidence.

Execution steps

  1. 01

    Bind tenant and workspace to retrieval

  2. 02

    Trim context blocks by role

  3. 03

    Isolate cache, session, and memory

  4. 04

    Handoff or block cross-boundary requests

Acceptance evidenceTenant-context signatureCache and session boundaryCross-boundary grant or denial
Context isolation: Do not mix context across tenants, projects, or roles flow, SOP, and evidence
04

Model routing

Choose a model by data boundary, not only cost or speed

Route by provider, region, training policy, egress, and task sensitivity, with an auditable decision before invocation.

Execution steps

  1. 01

    Read data sensitivity

  2. 02

    Match provider and region policy

  3. 03

    Block disallowed egress

  4. 04

    Record model, version, parameters

Acceptance evidenceModel provider and regionEgress policy and decisionCall version and context summary
Model routing: Choose a model by data boundary, not only cost or speed flow, SOP, and evidence
05

Retention and deletion

Make retention and deletion configurable and verifiable

Business records, audit logs, caches, backups, and model context have different lifecycles; define duration, deletion, and exceptions separately.

Execution steps

  1. 01

    Define lifecycle per data class

  2. 02

    Trigger deletion or anonymization

  3. 03

    Handle backup, index, and cache copies

  4. 04

    Keep deletion evidence and exception reason

Acceptance evidenceExpiry and deletion taskDeletion scope and resultLegal hold and exception
Retention and deletion: Make retention and deletion configurable and verifiable flow, SOP, and evidence
06

Access and incidents

Give subject requests and privacy incidents a clear path

Access, export, correction, deletion, and unexpected egress share one workflow with deadlines, owners, and impact scope.

Execution steps

  1. 01

    Receive request and verify subject

  2. 02

    Locate data, context, and logs

  3. 03

    Process, deny, or escalate

  4. 04

    Notify, review, and close

Acceptance evidenceSubject verification and scopeDecision and timelineImpact and notice record
Access and incidents: Give subject requests and privacy incidents a clear path flow, SOP, and evidence

Bring Privacy requirements into a real evaluation

We map the principle to an acceptance checklist for your data, workflow, deployment boundary, and owners.

Region, data, model, operations, and acceptance requirements still need to be confirmed item by item in the project assessment.
