PII redaction by record type: what personal data each business record holds

PII redaction depends on the record type: email and chat need entity redaction and channel scoping, tickets need tokenized identifiers, recordings need transcription and consent checks, and code needs secret scanning. Requirements are agreed with the company before any work begins, and referral partners never handle records.

Why use a record-type matrix for PII redaction?

PII redaction is not one task. Email, chat, tickets, CRM notes, call recordings and code each carry different personal data in different places, so the method that works for one fails on another. This matrix lists the common record types, the personal data they usually contain and the redaction methods that are typically considered. Every requirement is agreed with the company before any work begins, and a referral partner never touches the records.

Use it to ask better questions of a company contact, not to design a redaction plan. Redaction is also not the same as permission: removing names does not create a right to license.

Which methods are used, and what do they do?

Method	What it does	Best for	Watch out for
Deletion	Removes the field or message	Fields with no training value	Loses context
Masking	Replaces characters with placeholders	Account and ID numbers	Pattern can remain identifying
Tokenization	Swaps a value for a consistent token	Names and IDs that recur	Keeps links between records, so key handling matters
Generalization	Reduces precision	Dates, ages, locations	Rare values can still point to a person
Named-entity redaction	Finds names and places in free text	Email, chat, notes	Misses nicknames, typos, context clues
Transcription then redaction	Converts audio to text, then redacts	Call recordings	Voice itself is identifying
Secret scanning	Finds keys and credentials	Code and configs	Old commits still hold secrets

What personal data sits in each record type?

Record type	Typical personal data	Usual redaction approach	Extra question for the company
Email	Names, addresses, signatures, phone numbers, attachments	Entity redaction, drop attachments or scan them	Are personal mailboxes mixed with business ones?
Slack or Teams chat	Handles, mentions, links, shared files, private channels	Tokenize handles, exclude private channels	Which channels are in scope?
Support tickets	Customer names, order numbers, free-text complaints	Tokenize IDs, redact entities in notes	Do customers upload documents?
CRM notes	Contact names, titles, deal notes	Entity redaction, field-level deletion	Whose contacts are they?
Call recordings	Voices, spoken names, account details	Transcribe, redact, handle audio separately	Were notices given and consents obtained?
HR and payroll	Salaries, IDs, benefits	Usually excluded	Is it in scope at all?
Source code and git	Author emails, secrets, test fixtures with real data	Secret scan, rewrite author fields	Are real customer records in test data?
Finance and invoices	Bank details, tax IDs, signatories	Mask, tokenize, exclude	Which counterparties' terms bar use?

What should the company have answered before a redaction plan?

Scope

Which systems and date ranges are in the data inventory?
Which folders, channels or mailboxes are excluded?
Are the records mainly business-to-business, or mainly consumer personal data?

Rights

Do customer contracts, privacy notices and employee policies allow the use?
Has counsel reviewed any recordings, health information or financial account data?
Does any client or outsourcer own the content?

Method

Who owns the redaction task, the company or SourceX's team?
Is a key kept for tokens, and who holds it?
How will leftovers be sampled and checked?

Several laws give consumers rights over their personal information. California's privacy regulator publishes an overview of the CCPA covering rights to know, delete and opt out of sale or sharing. Call recording is governed federally by the Wiretap Act and by state consent rules that vary. This is general information, not legal, tax or financial advice. Confirm with your own counsel before acting.

Which records carry the heaviest limits?

Health information is the sharpest case. Billing and claims notes can contain protected health information, which is covered in medical billing company data. Aviation, freight and other regulated records raise different ownership issues, for example who owns aircraft maintenance records. Structured decision logs such as architecture decision records and freight claims files tend to hold fewer personal details than raw email, but names still appear.

How should a partner use this matrix?

Ask the sponsor which record families they would put in scope, using the table above as a vocabulary list.
Note "yes", "no" or "unsure" for each, nothing more.
Do not ask for samples, screenshots or exports.
Introduce the company, and let SourceX and the company agree redaction in writing before work starts.
Data is delivered only after an executed agreement and the company's authorization.

What are red flags?

Data is mainly consumer personal information with no licensing basis.
Data is mainly PHI without HIPAA authorization or de-identification.
Nobody can export the data.
Records belong to a client who has not consented.

Next step

When the company's contact answers the scope questions comfortably, register as a partner and send the introduction. The company can list its systems with the data inventory builder, and who qualifies sets out the company baseline.

Step 2Company appliesThe company applies itself at /apply.
Step 3Buyer selects and paysThe buyer selects and pays for the data and SourceX receives its fee.

Common questions

What is the difference between redaction and de-identification?

Redaction removes or masks specific items in a record. De-identification is a broader goal, reducing the chance that a person can be identified, and in health data it has a defined legal standard. Either one is a technical treatment, and neither automatically gives the company the right to license the data.

Can automated tools redact everything?

No tool catches everything. Free text contains nicknames, misspellings and indirect clues. Teams usually combine automated detection with sampling and human review of the output. The method, error tolerance and review process are agreed with the company before any work starts.

Do call recordings count as personal data?

They can, because voices and spoken details can identify people, and recording consent rules vary by state and by whether notice was given. Recordings are often handled separately from text, and some companies exclude them. The company's counsel should decide.

Does a partner need to know redaction methods?

No. A partner only needs enough vocabulary to ask sensible scope questions and to avoid promising anything. The company and SourceX decide the methods in writing before any work, and the partner never handles records.

Is source code personal data?

Code itself usually is not, but commit history carries author names and emails, and tests or fixtures sometimes include real customer records or secrets. Companies typically scan for credentials and review fixtures. Git history matters for value, so removing it entirely has a cost.
