5 Best PII Targeted Redaction Models and APIs for 2023

Thriving in a privacy-aware world is a challenge for most organizations. Thankfully, PII redaction models and APIs can help them navigate the challenge.

Get this — around 327.77 million terabytes of data is collected daily, and this year alone, 120 zettabytes of data will be generated. This unprecedented hike has increased reliance on PII Redaction to ensure confidential and sensitive data privacy.

You see, it becomes next to impossible to manually remove sensitive information from the wealth of data within documents, audio, videos, and other digital media files.

And to not breach customer trust and abide by mandated data protection compliances, companies (healthcare, finance, transportation, insurance, call centers, etc.), governmental organizations, law enforcement agencies, and other legal entities must ensure all shared data gives away what is required and nothing else.

In the wrong hands, PII information can be used to narrow down one’s individuality and use it for identity theft and unauthorized card transactions, among other fraudulent activities.

To make matters worse — upholding privacy has gotten much difficult as data breaches have consistently increased, and so are the financial costs associated with them. According to IBM, the global cost of a data breach averaged $4.45 million in 2023.

Among the huge pile of data generated lies a significant share of personally identifiable information (PII).

Because of the highly sensitive nature of PII, various PII redaction artificial intelligence (AI) models and APIs have emerged in the market.

This blog will delve into the best PII redaction AI models and APIs for 2023 and beyond.

What is PII Redaction?

PII redaction refers to the act of simply concealing or hiding sensitive information that, if revealed, could be used to identify an individual or an entity.

Usually, this is achieved by blurring, pixelating, or placing a black box on the sensitive data to protect its integrity.

What PII Needs to be Redacted?

Faces, license plate numbers, names of individuals and organizations, locations, zip codes, social security numbers (SSNs), taxpayer identification numbers, credit card details, phone numbers, etc., are all examples of PII.

In today’s digital landscape, redacting personally identifiable information (PII) is as essential as breathing. In short, there is no survival without it.

Why PII Redaction is Important?

We are living in a privacy-aware world. With the rise of new and emerging technologies, data privacy challenges have also seen an uptick.

Every day, users enter their personal information to conduct transactions, including their names, locations, email addresses, financial information, and more.

Not only this but various laws and compliances have tightened the noose around organizations when it comes to upholding data privacy and protection.

Laws such as the California Consumer Privacy Act (CCPA), Health Insurance Portability and Accountability Act (HIPAA), General Data Protection Regulation (GDPR), and Freedom of Information Act (FOIA) have resulted in an increased focus on ensuring the integrity of personal data kept within databases.
