Governance

De-identification Framework

NexClinAI follows a structured, multi-layered de-identification workflow designed to remove direct and indirect identifiers while preserving practical clinical utility for AI development, validation, and research use cases.

Primary Goal

Protect privacy without breaking downstream usability

Privacy-aware execution with workflow discipline.

Core Methods

Metadata removal, redaction, normalization, QC

Structured rather than ad hoc processing.

Operating Models

On-site or NexClinAI-managed execution

Chosen based on partner and regulatory needs.

Compliance Position

HIPAA, GDPR, DPDP aware

Framework-aligned handling, not empty claims.

Core Principles

The framework is built around privacy control, practical utility, and traceable execution

The objective is not only to remove identifiers, but to do so in a way that remains usable for the intended AI or research workflow.

Identifier Removal

Direct and indirect identifiers are removed through structured metadata and image-level workflows.

Clinical Utility Preservation

The framework preserves attributes needed for AI development, validation, and research workflows.

Multi-Stage Validation

Automated checks and manual review are used together to detect residual privacy risk and structural issues.

Traceable Execution

Handling logic, QC, and release discipline are organized for accountability and auditability.

Portrait Workflow

A controlled path from intake to validated delivery

This workflow is designed to reduce residual privacy risk while keeping output structured, reviewable, and commercially practical.

Step 01

Secure Intake

Controlled transfer or partner-side intake under defined handling rules.

Branch A

On-Site Model

On-Site De-identification

Processing stays within the hospital or partner environment before validated release.

Branch B

NexClinAI Model

NexClinAI Processing

Data is transferred to NexClinAI’s controlled environment for standardized processing and QC.

Step 02

Pre-Processing

Validation, file organization, and workflow-specific preparation.

Step 03

Metadata De-ID

DICOM headers and metadata are stripped of direct and indirect identifiers.

Step 04

Pixel Review & Redaction

Burned-in identifiers are detected and removed through automated plus manual review.

Step 05

Normalization

Date shifting, structural cleanup, and project-level standardization where required.

Step 06

QC Validation

Residual risk, packaging consistency, and downstream usability are reviewed before release.

Step 07

Structured Delivery

Validated data is packaged and released in the format aligned to the client workflow.

Operating Models

Two execution models depending on partner controls and project requirements

NexClinAI supports both on-site execution and NexClinAI-managed processing depending on regulatory, institutional, and operational constraints.

NexClinAI Processing Model

Data is transferred to NexClinAI’s controlled environment, where de-identification, QC, and structuring are performed through standardized internal workflows.

Centralized processing control

Standardized review and QC

Operationally efficient scaling

Full workflow traceability

On-Site De-identification Model

De-identification is performed within the data partner’s infrastructure using approved tools and defined process controls before validated data is transferred.

Raw data stays on-site

Useful for stricter environments

Partner-controlled execution

Validated de-identified release only

Compliance-aligned handling, not checkbox language

The framework is informed by globally relevant privacy and de-identification principles. It is designed to support responsible data handling across cross-border AI and research engagements.

NexClinAI does not attempt to re-identify individuals from de-identified datasets, and does not permit or support such attempts by clients or partners.

HIPAA Safe Harbor-informed handling

GDPR anonymization-aware principles

DPDP-aligned privacy approach

Controlled release and no re-identification stance
