Techopedia Explains Partial Document Encryption

The most common type of partial document encryption involves encrypting each separate page or component of a document separately. This is sometimes called “on-demand” encryption. The idea is that, when a certain piece of the document is requested, it goes out encrypted with its own security certificate. This allows administrators to get around the burden of encrypting the entire document based on a request.

In order to implement partial document encryption, security experts need specific algorithms that will encrypt only the desired portion of a file or document.

Although this method is currently prominent, in the future, partial document encryption may also be used to describe methods that only encrypt parts of a document on a word-by-word basis as a form of digital redaction for more precise security.
