OpenText Blazon: automated document redaction in the cloud


In today’s business world, there’s an increased focus on privacy and security. When publishing or distributing documents containing personal data, it’s essential to remove or hide confidential information first. But manual redaction can be a tedious, time-consuming process. What if you could make content compliance quick and hassle-free? 

OpenText Blazon

With OpenText Blazon, you can automatically redact all sensitive text from any document. You can start with virtually any file format and convert it into a new PDF, TIFF or secure Content Sealed Format (CSF) version of content where black bars replace the sensitive data. You can choose to redact data based on search strings, fixed redaction zones, regular expressions or even macros. Even paper documents or files that are not searchable can be converted thanks to Blazon’s OCR capabilities. 



To start the redaction process, you have to start by analysing a sample set of documents. This has to be done to find out which sensitive information needs to be redacted and where this information appears on the documents. Based on this analysis, a redaction script must be written for Blazon to start redacting your documents. 

GDPR Compliancy 

The words need to be redacted in a document to fully comply with the GDPR can vary between companies, industries or even projects within the same company. Sensitive information can be a name, home address, date of birth, social security number, or even salutations such as “Sir” or “Madam”. A black bar with optional text will replace these words so they are completely removed from the document, its text layer and metadata. The document is now GDPR compliant.

Automated redaction in the cloud 

To showcase the capabilities of automated redaction to prospects, we’ve integrated OpenText Blazon into a web browser. We did this by using the Captiva as a Service (CaaS), integrating Blazon in a Captiva data capture process.

By combining Captiva with Blazon, you can upload documents that will enter the process through Captiva. This information gets redacted by Blazon and the resulting document can be sent to the appropriate location for further processing, e.g. an email address or a different platform.  

Once Blazon is successfully integrated into the cloud, it can easily be accessed on multiple devices to process individual files or large batches. No additional configuration is required. 

In conclusion

OpenText Blazon can be integrated with Captiva in a fairly short time frame. You start by making a Captiva Userflow and deploying it on CaaS. Then you just need to set up Blazon and transfer its output through Captiva. The benefit of integrating this software into the cloud is so it can easily be accessed by multiple users without additional configuration.
