Top Free Document Redaction tools, APIs, and Open Source models

What is Document Redaction API?

The Document Redaction API, also known as PII Redaction, is an interface that assists software developers in adding redaction capabilities to their applications. It is similar to the Document Anonymization API but is specifically designed for redaction purposes.

The API enables the automated removal of specific information in documents, including text, images, and other media. Its functions are user-friendly and easy to implement. Document anonymization aims to protect individuals' privacy by replacing or removing any personally identifiable information (PII) from the document.

‍

‍

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

Document Redaction APIs are commonly used for generating legal documents, managing government documents, and performing privacy-compliant redaction of medical records. For example, they can be used to comply with HIPAA regulations in the United States.

Top Open Source (Free) PII Redaction models on the market

For users seeking a cost-effective engine, opting for an open-source model is recommended. Here is the list of the best PII Redaction Open Source Models:

‍

1‍. OpenNyAI

This open-source model provides offline semi-automatic data redaction for legal documents by masking named entities identified using machine learning. The output of the redaction process must be reviewed by humans to ensure that all sensitive information has been properly masked.

‍

2. Codexify

Codexify enables users to redact sensitive data from CSV, Excel, and JSON files using a variety of redaction methods, such as fixed string, random value, and hash functions. This ensures that sensitive data is removed from the files while preserving the integrity of the remaining data.

‍

3. Phileas

Phileas is a Java library that redacts personally identifiable information (PII), protected health information (PHI), and other sensitive information from text. The library analyses the text to identify sensitive information such as names, ages, and addresses.

‍

4. Fuko Masked

Fuko\Masked is a small PHP library for masking sensitive data: it replaces blacklisted elements with their redacted values.

‍

5. Redact Engine

Protect confidentiality with dynamic redaction by replacing sensitive data from string or JSON format API Docs.

‍

6. PDF Redaction

Open Source Model for text redaction in PDFs.

‍

7. Redactable

AI-powered document redaction software.

Cons of Using Open Source AI models

‍While open-source models offer many advantages, they also have potential drawbacks and challenges. Here are some cons of using open-source models:

‍

• Not Entirely Cost Free: Open-source models, while providing valuable resources to users, may not always be entirely free of cost. Users often need to bear hosting and server usage expenses, especially when dealing with large or resource-intensive data sets.
• Lack of Support: Open-source models may not have official support channels or dedicated customer support teams. If you encounter issues or need assistance, you might have to rely on community forums or the goodwill of volunteers, which can be less reliable than commercial support.
• Limited Documentation: Some open source models may need more complete or better-maintained documentation. This can make it difficult for developers to understand how to use the model effectively, leading to frustration and wasted time.
• Security Concerns: Security vulnerabilities can exist in open-source models, and it may take longer for these issues to be addressed compared to commercially supported models. Users of open-source models may need to monitor for security updates and patches actively.
• Scalability and Performance: Open source models may not be as optimized for performance and scalability as commercial models. If your application requires high performance or needs to handle many requests, you may need to invest more time in optimization.
