Bulk Audio Redaction: Ensuring Compliance and Protecting Customer Data

Call centers in the US receive over 40 million calls daily. Each call's average handled time is 3 minutes, leading to hundreds of thousands of hours of recorded interactions each year.

A report reveals that 70% of customers would discontinue business with a company if they believed their data was compromised. This potential loss of customer trust underscores the urgency of implementing robust data protection measures.

Moreover, regulations like GDPR and CCPA mandate strict measures to protect personal information. Non-compliance with these regulations can lead to hefty fines, such as up to € 20 million or 4% of the company's annual turnover under GDPR and up to $7,500 for each violation under CCPA.

Considering these challenges, redaction software emerges as a crucial solution for call centers. These solutions assist with bulk audio redaction and ensure adherence to legal compliance, reassuring the business and its customers.

Understanding Bulk Audio Redaction for Call Centers 

With credit card numbers being read out loud in about 70 of 100 calls made to the call centers, the potential for hackers to access about 700 credit card numbers in 1,000 voice recordings is alarming. This quickly turns into potential revenue of $840,000 from sales of these credit card numbers on the dark web.

Therefore, call centers require audio redaction software to automate bulk audio redaction workflows, considering the scenarios in which they handle sensitive data obtained from customers over calls. These include:

Customer Identity Verification

Due to increasing identity crimes in call centers, verifying the customer's identity is imperative to prevent fraud. Even the slightest information requests require names, account numbers, and SSNs for compliance.

Over-the-Phone Payments

Card-not-present (CNP) transactions such as over-the-phone purchases are still prevalent. Customers disclose their credit card details, such as credit card numbers, CVV codes, and expiration dates, to the agents for purchase.

Call Quality Monitoring

The call centers also record customers' interactions to assess service quality. These recordings, which often include personal information, must be redacted in bulk before quality assurance analysts see them.

Agent Training

Recorded calls are also helpful to train call center agents. However, before sharing internally, all these recordings must be redacted using automated bulk audio redaction to preserve the customers' privacy.

Challenges in Bulk Audio Redaction and How to Overcome Them  

The following are the challenges in bulk audio redaction for call centers that can be mitigated by implementing automated redaction software. 

The Volume of Calls Handled by Call Centers

Call centers handle an immense volume of calls. As a result, a vast amount of audio data must be analyzed, and it may easily exceed hundreds of thousands of hours of recorded material per year. Handling such a large amount of data presents challenges, such as processing it effectively and scalability while ensuring that the information that needs to be redacted is appropriately processed.

Due to the large number of calls, even minor problems in redaction lead to time loss and a backlog of work. As each call produces a large amount of audio, it would be tough to process this manually. For this reason, call centers need to use automated solutions to address most of the redaction tasks.

With the rise in call volumes, the need for audio redaction solutions will also increase; hence, technology must be constantly improved.

Complexity of Identifying Sensitive Information

Detecting PII in call recordings is challenging because there are numerous data points and contexts in which it appears.

Names, addresses, and financial information are examples of PII, and they can be spoken in different contexts and tones, making automated detection challenging. The background noise, multiple speakers, and other accents made it worse, which are common in most real-world scenarios.

GDPR, HIPPA, CCPA, and PCI SSC are data privacy regulations that specify which data must be redacted to protect the consumer's privacy. However, extracting this information from a large amount of audio data takes work. Due to the complexity of this task, mistakes are made when employing less advanced redaction tools.

Another issue that makes the process complex is the requirement for accuracy and precision. Incomplete or incorrect redaction can lead to noncompliance with regulations, hefty fines, and legal consequences.

It is critical to enhance the accuracy of identifying sensitive information with the help of more sophisticated redaction tools. These technologies can identify patterns in speech and context, making it less challenging to find and redact sensitive information consistently and efficiently.

Time-Consuming Manual Processes

Manual audio redaction is tedious and time-consuming. Reviewers must listen to each recording and then manually redact the sensitive information. Considering the amount of data handled by call centers, this approach is not feasible and can hardly be considered efficient.

The manual redaction process also adds more work to the call center employees. The employees assigned to redaction tasks must spend time, which means the organization's efficiency will suffer. This inefficiency results in processing delays and possible non-compliance with regulatory requirements.

Manual processes are disadvantageous because they likely involve human errors, making compliance work harder. If a single piece of data is missing, legal and financial penalties can be severe. Automated solutions can manage these risks as they offer uniformity and efficiency in redacting all recordings.

Automated bulk audio redaction solutions are an excellent investment because they minimize the time and effort needed for audio redaction. Automation also enhances accuracy, a significant factor in avoiding compliance issues.

High Error Rates Leading to Compliance Risks

Manual redaction involves human intervention and hence is prone to human errors. Failure to recognize or redact sensitive information can lead to a breach of data privacy laws and regulations. As a result, severe penalties like fines and potential reputation loss.

Furthermore, high error rates also potentially cause customers to lose trust. Customers have the right to protect their personal information, and failure to do so can lead to loss of business. High accuracy of redaction work is essential to retaining customers' trust and keeping them using the Company's services.

Software-based redaction tools use technologies to improve the efficiency of the process and minimize the likelihood of mistakes. These tools can reliably detect and remove personal information, making adhering to data protection laws possible. The adoption of these solutions can assist call centers in overcoming the challenges posed by manual redaction.

Key Features to Look for in Audio Redaction Software

When selecting audio redaction software, consider the following features:

Accurate Speech-to-Text Transcription

The precise transcribing of audio into text helps search PII data in the audio. Moreover, accurate transcription helps optimize redaction activities by identifying the information that should be redacted.

PII Redaction Capabilities

The redaction software should have a feature that automatically redacts PII from audio. This includes:

• Names 
• Social Security Number
• Credit card details 
• Addresses 
• Phone numbers 
• Date of birth 
• Financial account numbers 
• Driver's license numbers 
• Passport numbers 
• Email addresses
