What is Document Redaction API?

A Document Redaction API, also called PII Redaction, is an interface that helps software developers add redaction capabilities to their applications. It is similar to the Document Anonymization API but focuses specifically on redaction.

It allows the automated removal of particular information in documents, such as text, images, or other media. This API has functions that make it easy to use and implement. Document anonymization aims to safeguard individuals' privacy by either replacing or removing any personally identifiable information (PII) from the document.

‍

‍

Both document redaction and document anonymization entail changing documents to safeguard sensitive information. Redaction concentrates on removing confidential details, while anonymization is centered on general privacy protection, for example, by deleting or substituting personally identifiable information.

Some common applications of Document Redaction APIs include generating legal documents, managing government documents, and performing privacy-compliant redaction of medical records (for instance, in compliance with HIPAA regulations in the United States).

PII Redaction APIs use cases

You can use Document Redaction in numerous fields, here are some examples of common use cases:

‍

1. Legal: Automate the deletion of personal information, including names and addresses, from legal documents and court filings to guarantee privacy and compliance with regulations.
2. Healthcare: Use document redaction application programming interfaces (APIs) to extract and redact patient information from medical files, ensuring the protection of confidential healthcare data while adhering to industry regulations.
3. Finance: Use document redaction APIs to automatically mask bank account numbers, transaction details, and other confidential information from financial documents, improving privacy and ensuring regulatory compliance.
4. Human Resources (HR): Enhance the privacy and compliance of employees by utilizing APIs for document redaction to remove personal information from human resources records, including employment contracts and reviews of performance.
5. Contract Management: Simplify and secure the contract management process by removing confidential clauses, pricing details, and other sensitive information from contracts, guaranteeing safe sharing with third parties.

Best Document Redaction APIs on the market

While comparing PII Redaction APIs, it is crucial to consider different aspects, among others, cost security and privacy. Document Redaction experts at Eden AI tested, compared, and used many Document Redaction APIs of the market. Here are some actors that perform well (in alphabetical order):

‍

• Base64.ai
• Private AI
• ReadyRedact
• Strac.io
• Super.ai

‍

1. Base64.ai - Available on Eden AI

‍

‍

Built on their ability to extract data from any document, Base64.ai's Redaction AI permanently deletes personally identifiable information (PII) and sensitive details such as names, dates, faces, signatures, and addresses, among others. This guarantees that data is shared only on a need-to-know basis.

‍

2. Private AI - Available on Eden AI

‍

‍

‍

Private AI allows users to find, remove or replace personally identifiable information (PII) found in documents, images, audio and video. Its API supports redaction in over 50 languages whilst adhering to the regulatory requirements for HIPAA, CPRA and GDPR compliance.

Users can choose to redact confidential information using a series of # symbols or replace the entities with synthetic data for added security. Its contextual NLP solution offers undeniably high performance straight out of the box with an accuracy rate of 99.5%. Currently supporting over 10 file formats including PDFs, DOCX, JSON and PNG.

‍

3. ReadyRedact - Available on Eden AI

‍

‍

‍ReadyRedact's Document Redaction API is easy to use and efficient. It can quickly remove sensitive data from your files using advanced pixel-to-pixel replacement technology. This will increase the level of protection for your documents and help ensure compliance.

‍

4. Strac.io

‍

‍

Strac.io's document redaction API scans the document, identifies and redacts sensitive information, all while preserving the original format. The API offers an optimal combination of user-friendliness and data security.

‍

5. Super.ai

‍

‍

Super.ai's Redact API can be used to redact images, videos, and documents. PII that can be redacted includes dates, vehicle identification numbers, license plate numbers, phone numbers, and other sensitive information.

To ensure privacy, the API airbrushes or replaces each redacted character with a pseudonym instead of simply using a # symbol. With 100% accuracy, their team ensures high-quality through post-processing for false positives and negatives.

Performance Variations of PII Redaction

PII Redaction API performance can vary depending on several variables, including the technology used by the provider, the underlying algorithms, the amount of the dataset, the server architecture, and network latency. Listed below are a few typical performance discrepancies between several Document Redaction APIs:

‍

1. Document Complexity: The format and structure of a document can affect the efficiency of redaction processes. Materials with intricate formatting, tables, or non-standard elements may necessitate more advanced redaction algorithms.
2. Volume of Documents: Redaction rules and policies can impact performance. Rules that involve pattern recognition or context-based redaction may take longer to process. Using customizable redaction rules can increase flexibility, but it may reduce the speed of redaction.
3. Security and Compliance Requirements: Stringent security and compliance measures, like encryption and secure data handling, could potentially increase processing overhead. Nonetheless, they remain critical for safeguarding sensitive information whilst conducting the redaction process.

Why choose Eden AI to manage your Document Redaction APIs

Companies and developers from a wide range of industries (Social Media, Retail, Health, Finances, Law, etc.) use Eden AI’s unique API to easily integrate Document Redaction tasks in their cloud-based applications, without having to build their solutions.

Eden AI offers multiple AI APIs on its platform among several technologies: Text-to-Speech, Language Detection, Sentiment Analysis, Face Recognition, Question Answering, Data Anonymization, Speech Recognition, and so forth.

We want our users to have access to multiple Document Redaction engines and manage them in one place so they can reach high performance, optimize cost, and cover all their needs. There are many reasons for using multiple APIs :

‍

• Fallback provider is the ABCs: You need to set up a provider API that is requested if and only if the main Document Redaction API does not perform well (or is down). You can use the confidence score returned or other methods to check provider accuracy.
• Performance optimization: After the testing phase, you will be able to build a mapping of providers’ performance based on the criteria you have chosen (languages, fields, etc.). Each data that you need to process will then be sent to the best Document Redaction.‍
• Cost - Performance ratio optimization: You can choose the cheapest Document Redaction provider that performs well for your data.
• Combine multiple AI APIs: This approach is required if you look for extremely high accuracy. The combination leads to higher costs but allows your AI service to be safe and accurate because Document Redaction APIs will validate and invalidate each other for each piece of data.
