A redaction software is a tool that can search and remove text, images, audio, and other content containing private, sensitive, or confidential information.

The tools help to reliably mask or remove sensitive information from a document, website, video footage, or another information source before sharing with other people not permitted to see all entire document.

Besides excluding the sensitive data, the redaction software and tools enable businesses to comply with various data protection regulations that prohibit sharing private information without a customer’s consent. Consequently, this improves the confidentiality and security of the data and customers while minimizing the commercial and regal risks for exposing personal information.

Usually, displaying credit cards numbers, bank accounts, and other sensitive information on documents, email messages, application dashboards, and other areas increases the risk of unauthorized access and theft of confidential data. Criminals can steal the data and exploit it to launch attacks, threaten the users, and sell the information, among many other crimes.

To reduce risks and comply with data privacy standards such as GDPR, PCI, and DSS, it is essential to remove all the sensitive information before sharing the content with the broader audience. For example, during litigation in the legal provision, the redaction process removes or blackouts the sensitive or privileged information from the documents before exchanging them.

Other desirable features include the ability to automatically track and provide a report of the redaction activities.
