Protecting sensitive spoken data is crucial for compliance and security. This blog explores how PII Redaction Software helps businesses automatically detect and remove personally identifiable information (PII) from audio and video recordings, ensuring compliance with GDPR, HIPAA, and other privacy regulations.

You think your business is secure. Firewalls, encryption, multi-factor authentication—you’ve covered all the bases. But have you ever considered that the biggest data vulnerability isn’t in your databases? It’s hiding in plain sight in your recorded calls, meeting transcripts, and voice logs.

Whether you're a compliance officer, IT security leader, or call center manager, your organization handles an overwhelming amount of spoken personally identifiable information (PII). Names, credit card numbers, addresses, Social Security numbers—it's all there, woven into everyday conversations.

In fact, according to the IBM Cost of a Data Breach Report (2024), the average cost of a data breach has reached $4.88 million, with call centers, financial institutions, and healthcare providers being prime targets due to their extensive collection of sensitive customer data.

A single leaked call recording or compliance failure could result in severe financial penalties and irreparable reputational damage. For example, British Airways was fined £20 million in 2020 for a data breach that compromised customer information, while Marriott International faced a €20.4 million penalty under GDPR for failing to protect guest data.

These significant penalties highlight the financial risks of non-compliance. In industries where personally identifiable information (PII) is frequently exchanged, such as healthcare and banking, the consequences can be catastrophic.

For instance, the 2015 data breach at Anthem Inc., a major health insurance provider, exposed nearly 80 million patient records, resulting in a $16 million HIPAA settlement—the largest to date. In banking, the Capital One data breach 2019 compromised over 100 million customer accounts, leading to an $80 million fine from the Office of the Comptroller of the Currency (OCC). These incidents underscore the severe financial and reputational risks of failing to protect PII.

Most organizations don’t even realize they’re storing unprotected PII in their audio data—until it’s too late. One leaked call. One lawsuit. One massive compliance failure.

So, what’s the fix? PII Redaction Software is designed to automatically detect and remove sensitive spoken information, ensuring compliance and security. But before we get to that, let’s discuss the real problem.

Unprotected Spoken PII Is a Privacy Landmine

Every industry that records conversations is a walking compliance risk:

Call centers store thousands—or even millions—of customer interactions. For instance, a large call center operated by multinational companies can record millions of calls annually, each potentially exposing credit card details and personal identifiers if not properly secured.

Financial institutions record calls for compliance purposes but overlook the spoken account details lurking in their databases. For example, during customer service interactions, clients often provide sensitive information such as bank account numbers, credit card details, and Social Security numbers. In 2020, Wells Fargo faced scrutiny after a call recording containing unredacted account information was leaked, exposing thousands of customers to potential identity theft. These incidents highlight the importance of securing spoken data within financial institutions.

Healthcare providers conduct telemedicine sessions that include sensitive patient information, risking HIPAA violations. For example, during virtual consultations, patients often share personal health details, insurance numbers, and prescription information. In 2019, American Well (Amwell), a major telehealth provider, faced backlash after a breach exposed thousands of recorded sessions containing confidential medical data.

Additionally, healthcare call centers handling appointment bookings or billing inquiries frequently record calls where patients disclose Social Security numbers and medical histories, further compounding privacy risks.

Law firms record depositions and client calls containing privileged legal information that must be safeguarded.

Most businesses don’t even know what’s in their audio archives. And if a regulator came knocking today, could you confidently say you’re not storing unredacted PII?

Here’s the truth: audio data is as sensitive as written data, yet most security policies don’t address it properly.

The Cost of Ignoring Spoken PII Redaction

Overlooking the importance of redacting spoken PII can expose businesses to severe legal, financial, and reputational risks. As regulatory bodies tighten data protection laws, organizations must prioritize safeguarding audio data as rigorously as written data. Below are some costs associated with the ignorance of spoken PII redaction.

Regulatory Fines: The High Price of Non-Compliance

Privacy laws like GDPR, CCPA, HIPAA, and PCI DSS were designed to protect sensitive information—regardless of whether it’s written, typed, or spoken. Organizations that fail to comply face significant financial repercussions. For example, GDPR penalties can reach €20 million or 4% of annual turnover for failing to protect personal data. Similarly, healthcare providers can be fined up to $1.5 million per year for violations under HIPAA. Financial institutions aren't exempt either—the Office of the Comptroller of the Currency (OCC) fined Capital One $80 million in 2020 following a customer data breach.

Data Breach Costs: Real-World Examples of Catastrophic Failures

Ignoring the need for spoken PII redaction can result in devastating data breaches. A notable example is the 2023 MOVEit data breach, which exposed 77 million records across government agencies, financial institutions, and healthcare providers. The breach resulted in millions in legal penalties, proving how unprotected data can have severe financial and reputational consequences.

In the banking industry, the Equifax breach in 2017 compromised the personal data of 147 million people, resulting in a $425 million settlement with the Federal Trade Commission (FTC).

Reputational Damage: Losing Customer Trust

A privacy scandal can erode customer trust and drive business away faster than any public relations campaign can repair. For instance, after the Facebook-Cambridge Analytica scandal, Facebook faced widespread backlash, leading to a $5 billion fine from the FTC and a significant drop in user trust and engagement. In the healthcare sector, providers who fail to protect patient data risk losing the confidence of their patients, leading to a decline in service utilization and revenue. Financial institutions like banks and credit unions face similar reputational risks if customer financial data is compromised.

Operational Inefficiencies: The Hidden Costs of Manual Redaction

And let’s be honest: manually scrubbing PII from audio is not a sustainable solution. Some businesses still rely on manual transcription and redaction, where employees listen to hours of recordings and manually censor sensitive information.

Let’s say your company records 10,000 hours of calls per month. Even at a conservative estimate of $50 per hour for manual review, that’s $500,000 per month just for redaction—a figure that can cripple operational budgets. This manual process can also delay customer service responses and reduce operational efficiency.

Manual Redaction is a Nightmare

Despite advancements in technology, some businesses still rely on manual transcription and redaction processes, where employees painstakingly listen to hours of recordings to censor sensitive information. This outdated method presents multiple challenges that can hinder operational efficiency and compromise data security.

Why Manual Redaction Falls Short

Manual redaction might seem straightforward, but several challenges make it less effective than automated solutions. Here’s why it often falls short:

Time-consuming

Redacting hours of recordings take… well, hours. Employees must meticulously comb through each recording, significantly delaying data handling and slowing overall productivity.

Expensive

The cost of hiring dedicated teams to manually redact recordings quickly adds up. It requires considerable human resources, and the time investment translates directly into financial overhead.

Error-prone

Human reviewers, no matter how diligent, are susceptible to mistakes. This increases the risk of missing sensitive PII, leading to compliance gaps and potential data breaches.

Yet, there’s a better way: Automated PII Redaction Software.

How PII Redaction Software Protects Privacy

To mitigate the risks of unprotected spoken PII, businesses need a reliable solution that ensures compliance and efficiency. Automated redaction technology offers a seamless way to detect and remove sensitive data, safeguarding information before it becomes a liability.

And it’s not just about compliance—building trust with your customers.

How Does PII Redaction Software Work?

To better understand how PII redaction software protects sensitive information, let’s look at some simple steps in the process:

Step 1: Audio/Video Upload and Transcription

The process begins with uploading the audio or video file. The software then generates a transcription of the spoken content, converting it into text for further analysis.

Step 2: Named-Entity Recognition (NER)

Named-entity recognition (NER) is applied to the transcription to detect personally identifiable information (PII) such as names, addresses, credit card numbers, and Social Security numbers.

Step 3: Redaction of Identified PII

Once PII has been identified through NER, the software proceeds to redact the sensitive information. This redaction can include muting, beeping, or removing the PII from both the audio and text transcriptions.

Step 4: Secure Storage & Compliance Integration

After redaction, the recordings can be securely stored or integrated into existing CRM, compliance platforms, or cloud storage solutions to ensure they meet regulatory standards.

With this method, automated spoken PII redaction achieves high accuracy rates, efficiently safeguarding sensitive information and surpassing the capabilities of manual review processes.

Industry Use Cases

Different industries face unique challenges in protecting sensitive data within recorded conversations. Implementing PII redaction software helps organizations across sectors maintain compliance, streamline operations, and protect their stakeholders' privacy.

Law Enforcement

Police departments and investigative agencies collect sensitive information through body-worn cameras, 911 calls, and interviews. For example, body camera footage from public protests often contains identifiable faces and license plates. Redaction software helps automatically blur or mute such details, safeguarding witness identities and confidential case information while ensuring compliance with Criminal Justice Information Services (CJIS) standards.

Legal

Legal professionals handle privileged client conversations, depositions, and discovery materials that require strict confidentiality. For instance, during high-profile court cases, recorded depositions might contain sensitive personal information that, if leaked, could influence public perception or compromise the case. Automated redaction ensures compliance with the ABA Model Rules of Professional Conduct and the Federal Rules of Civil Procedure, protecting client confidentiality.

Government

Public agencies must redact sensitive information before responding to Freedom of Information Act (FOIA) requests. For example, city councils often receive FOIA requests for recorded public meetings, which may inadvertently contain confidential information about citizens or ongoing investigations. Automated redaction accelerates the process while maintaining compliance with transparency laws and protecting sensitive data.

Education

Schools and universities manage student records, recorded lectures, and administrative documents containing FERPA-protected data. For instance, recorded virtual classrooms might inadvertently capture student names, grades, and other personal information. Redaction software ensures student privacy is upheld while maintaining academic integrity and compliance with the Family Educational Rights and Privacy Act (FERPA).

Transportation

Airlines, railways, and logistics companies process passenger manifests, booking records, and recorded customer service calls. For example, airlines record booking calls that may include sensitive travel information and payment details. Automated redaction ensures compliance with FAA and ISPS regulations, securing personal travel data and safeguarding customer information.

By integrating automated PII redaction software, these industries achieve regulatory compliance and strengthen customer trust and operational efficiency.
