Secure PDF Documents with Protected Watermarks

An organization's digital documents do not leave a paper trail once they leave the data center. They will likely be transferred and change hands inumerable times, all outside of the control of the document's creator. The capability of a company or institution to ensure ownership of their documents is essential. Whether they be digitized letters as part of a collection in a museum or a press release on behalf of a PR firm's most essential client, marking ownership of the document provides essential context on where it originated from and who to contact for more information. The pdfRest API Toolkit provides two easy tools to mark and secure documents for public consumption.

Watermark PDF API Tool allows you to digitally stamp a logo or block of text across a document using the same technology that powers watermarking functions in Adobe® Acrobat™. You choose the location, opacity, rotation, font, colors, and more. You can also chain requests to place both a logo and text, if for example you needed to identify your company logo as well as contact information for the originating department.

Restrict PDF API tool is an essential second step in securing your ownership of this document. PDF watermarks are designed to be removable, and this can be done easily with Adobe Acrobat. Running your document through the pdfRest Restrict PDF tool allows you to set a number of security restrictions on the document. By locking the viewer's ability to edit the document behind a SHA-256 encrypted password, you ensure that wherever that document ends up, and whoever has access to it, they will not have the ability to remove your watermarked logos or text identifiers. Restrict PDF also allows you to lock down a number of other security-focused features, such as the viewer's ability to copy/paste content and print the document.

With the combination of the Watermark PDF and Restrict PDF API Tools, pdfRest allows organizations to maintain ownership and security of their documents, even when those documents leave their control. Try both tools (and dozens more) for free by Getting Started now!
