Significant enhancements to its high-security Drumlin PDF reader/publisher and associated digital rights management (DRM) service were announced today by Drumlin Security (http://www.drumlinsecurity.co.uk ). Multi-language operation, Apple Mac support, Secure watermarking and a range of new secure distribution and Licensing options are new facilities included. Coupled with a very competitively priced digital rights management (DRM) service, the Drumlin service has a zero entry cost and includes its free or licensed Drumlin PDF reader/publisher.

The Drumlin software and service ensures that PDF versions of documents such as financial statements, courseware, technical manuals, market research reports, books, subscription newsletters, contracts and similar materials can be distributed with complete safety. Without concern that they might be intercepted, read, decrypted or copied, the fully secured version of PDFs created using the Drumlin software can be placed on a web site, CD or emailed to a user or customer.

Publishers are enabled by "Secure watermarking" to add an invisible watermark to their documents that is only enabled when the document is printed. The watermark can identify the details of the person printing the document, the computer on which it has been printed and the date and time of printing.

Via a special variant of the standard software which will run on the many Mac Windows emulators "Apple Mac" support is provided.

A full-functionality viewer for PDFs and secured PDFs is provided by the "reader" features in the Drumlin PDF reader/publisher. Its PDF handling is built upon the market-leading PDF software development library PDFNet SDK from PDFTron Systems Inc. (http://www.pdftron.com ) which supports all existing levels of PDF. Ensuring that the Drumlin reader is not at risk from the widely reported problems of viruses associated with some other PDF readers, Javascript and attached objects are disabled.

With the option to ensure that they can only be read once they have been authorized, The "publisher" facility in the Drumlin PDF reader/publisher strongly encrypts conventional PDF files. Even then, these files can only be opened on the individual PC on which they have been authorized - such files cannot be copied and read elsewhere. Enabling or disabling text copy facilities; setting start and end dates for viewing; and specifying the number of times a document may be viewed, and the number of times it may be printed (if at all), are enabled by Drumlin's publisher facility along with other controls to be applied to such documents.
