Excel Software has announced an update to its project- and document-protection application, DocProtect 1.1. The program is designed to protect rights and prevent access to HTML projects, image collections, video and audio files, PDFs, and Excel spreadsheets for all non-licensed users. The latest version enables users to release and restore licenses between computers, while adding a new PDF-style subscription model for newsletter and magazine publishers.

The software also features enhanced support for handling large image collections, along with additional licensing capabilities through WebActivation and Safe Activation license servers.

DocProtect 1.1 is compatible with Mac OS X 10.1 or later. Pricing starts at $495 as a single-license version for either Mac or Windows, while a cross-platform package can be purchased for $795.
