Document Data Governance: Desensitising as a By-Product

The Privacy Conversation Needs to Shift - From Privacy Awareness to Impact Readiness

We hear about data privacy everywhere – in the news, in trainings, leadership meetings. But here’s the reality: many breach disclosures still read the same way:
“Yes, we were hacked, but no customer data was compromised.”

That narrative leads to complacency. It suggests our current processes are “good enough.” But what happens when the next breach isn’t just an information leak?

Unique Identifiers - account numbers, driver licence numbers, passport numbers, tax file numbers (TFNs), employee IDs, or even some unique transaction IDs - can all be weaponised. If they fall into the wrong hands, attackers can combine them with public data to:

• Impersonate individuals and open lines of credit
• Take over accounts using social engineering
• Establish fraudulent social profiles to amplify harm

For businesses, it’s similar: compromising even a single user ID or API key can lead to lateral movement (techniques that a cyber attacker uses, after gaining initial access, to move deeper into a network in search of sensitive data and other high-value assets), operational outages, and brand damage. Many incidents get reported as “no adverse impact observed but we are taking precautionary measures” - but the true impact can surface months later when leaked data is combined with other sources. So, we should endeavour to “nip it in the bud”.

Why Documents Are a High-Risk Vector

In a digital-first world, documents are dense containers of sensitive data:

• Bank statements and payslips
• Copies of driver licences and passports
• Tax returns and ATO correspondence
• Insurance forms, loan applications, onboarding packs
• Invoices, remittances, purchase orders, contracts

These contain both structured and unstructured PII/PHI/PCI, often hidden in images, scans, handwritten fields, or attachments. Some organisational systems are few decades old and may hold millions of documents with sensitive data. Governance here is not optional, it’s existential.

Desensitising as a By-Product: Privacy by Design in Action

The most sustainable approach is privacy by design: building governance into the flow of work so desensitising becomes an automatic outcome, not an afterthought. A practical sequence:

1. Detect & Classify - Use OCR/ICR, ML and GenAI to identify document types, entities, and sensitive fields (e.g., licence number, TFN, bank account, DOB, customer reference numbers, credit card numbers, usernames).
2. Label & Policy-Map - Label content (e.g., Confidential, PII, Private) and map to policies and rules (who can see what, where it can be stored, how long to keep it).
3. Desensitise - Automatically redact or masquerade/mask data points at ingestion or in-flight. Preserve the original only where justified (with least-privilege).
4. Route Exceptions - If confidence is below threshold or a human review is required, route to approved users with highlights and citations. Reduce errors with QA sampling.
5. Audit & Prove - Log everything: policy applied, number of fields detected and redacted, users who accessed, timestamps, and retention actions. This is your assurance trail.

When this is baked into your document automation, governance happens by default, not by heroics.

How Tungsten TotalAgility Helps

Tungsten TotalAgility brings together data processing, AI/ML, workflow, and integrations so organisations can operationalise governance:

1. PII/PHI/PCI Detection: Recognise sensitive entities in machine-printed, scanned, and handwritten content. Easily detect custom entities such as usernames or customer reference numbers.
2. Automated Redaction & Masking: Apply full blackout or partial masking to avoid “over-redaction” that could lose business value. Control when the redaction is applied temporarily or becomes permanent.
3. Human-in-the-Loop Review: Route low-confidence cases to curated queues where users see precise highlights and source citations showing where the data was detected. TotalAgility provides a best-in-class user experience to handle documents.
4. Repository & Line-of-Business Integrations: Connect to ECM/DMS (e.g., SharePoint, Salesforce, Content Manager, etc.), line-of-business apps, and ERPs/CRMs to harvest, classify, and desensitise documents at scale.
5. Workflow & Orchestration: Build intuitive, auditable flows with SLAs, escalations, approvals, and role-based access.
6. Retention & Policy Hooks: Tag content with retention codes, trigger deletions/holds, and push clean metadata downstream.

If you already automate document-centric processes with TotalAgility, desensitising often comes as a byproduct of the same workflows, less lift, more value.

Summary

Rather than staying complacent, uplifting your document automation workflows is low-hanging fruit. By embedding desensitisation into these processes, your organisation sets itself on the path to default document data governance - reducing or even eliminating risk without heavy lifting.
