Drumlin Security

Pacifica Military History, http://www.PacificaMilitary.com
"I selected the Drumlin system following a long search and had several good reasons for doing so. Chief among these is the ability to utilize complex graphics, especially high-resolution photos. This is thanks to use of Adobe Acrobat pdf files as the foundation. My pictorial books were otherwise out of the running for commercially available ebooks featuring robust DRM, and all of my books retain exactly the formatting values I can build in to pdf presentation. Of course, having a robust DRM is key factor. Ease of set-up for new files is important, as is the fact that the software is free and that the learning curve is short. Drumlin is receptive to adding new features based on customer demand; I asked for bookmarks, and the bookmark feature became available in a few days! Another vital feature gives me complete control over assigning activation codes direct to my customers.

All in all, I'm happy with the choice and I plan to make continued use of the Drumlin system as the stand-alone ebook reading system available to my customers."

Most of our users want to publish one or more ebooks, technical manuals or similar documents which they have in PDF format but wish to ensure are truly secure from copying and/or have other controls applied to them. The terms and conditions for using this software and service are provided in the Software License document issued with each copy of Drumlin. Please also see the About page for more details regarding the website and DRM service usage terms.

The simplest way to achieve this, at no cost, using the Drumlin software and service is:

1. Download, install and register the free Drumlin reader/publisher software (to obtain the software for Drumlin V4 please Download from here - 2.4 Mb zip file)

For the strongest security and where you do not necessarily know who your users will be in advance then follow steps 2, 3 etc below. If you know all your users in advance (e.g. they are your in-house engineers or sales people, or are members of an existing group), then you may wish to use an alternative approach - click here for more details.

2. Use the File menu, Publish option and select a test PDF on your PC/network for secure publishing - choose the Fully secured DRMX file option and set the other options you would like to use as controls (e.g. View=5, Print=0, End date=31st December 2010) and press the OK button. You need to have an active Internet connection at this stage.
Printing Notes:
Print#: to disable all printing set to 0 or use the new Disable printing option. Set to -1 for unlimited printing. Set to a number, e.g. 2, to permit printing 2 times. Note that if a user opted to print on two occasions and only printed the current page each time, they will no longer be able to print any more pages. The alternative is to set Print#=-1 and then add a PrintPages# entry (e.g. for the total number of pages in your document)
PrintPages#: This option only applies if Print# is not set to 0. In most cases set it to -1 (unlimited). It specifies the number of pages that may be printed overall (i.e. across all sessions of printing that are permitted)
Network printing enabled: This option only applies if Print# is not set to 0/not disabled. It permits printing to network printing devices as well as locally connected devices
Printing to file/PDF printers etc. is not permitted for any Drumlin documents

3. Drumlin then sends strongly encrypted control information (NOT THE PDF FILE ITSELF) to our server. This includes the information necessary to identify your file (including the file name, your details and the controls you have applied) together with other security information. This information is stored on the server. At the same time your PDF file is strongly encrypted and the encrypted version is saved on your PC/chosen location with the file extension .DRMX. Your original PDF file remains unchanged. A test authorization code is automatically sent to you to check your DRMX file, as if you were an end user - see steps 4 and 5 below. Ask us if you would like additional codes for test documents. Quick tip: If you have several PDF files you wish to publish for individual users you can combine these first into one PDF (e.g. using Adobe Acrobat) and create a single encrypted file and will need only one code for all the PDFs for a customer.

4. You can now send the DRMX version of your PDF file to anyone you wish or place it on a web site for downloading (if you have any problems with this please let us know - first check the answer to  Q22 on the FAQs page) - it is secure and cannot be used/read. To make the file readable it needs an authorization code, which you will provide. You get this code from us (contact us by email  to obtain codes, stating the DocID and/or document name for which you require codes - you must identify yourself as the publisher and do this from your registered Drumlin email account) - we actually send you blocks of codes, up to 100 at a time, as text files - it is up to you to keep these safe and distribute them to your customers/users. Normally codes can only be used once, but you can ask for a set of codes that can be used 2 times or more if you wish.

5. Your customer, the end user, will need to know what to do in order to read your secured PDF. Typically you will send them an email, with simple instructions, possibly linked to a web page (see http://www.pdf-publishing.com/Ebooks_Guide.htm  for an example). Typically your email will also include an authorization code for them to use.

6. Your customer now has the software installed and registered, your DRMX file, and an authorization code from you for that document. As noted above, you can provide this by email or automatically via your online service, or via a commercial service such as PayLoadz. The end customer uses the File menu, Authorize option and selects the DRMX file you have provided, and then they enter the authorization code they have been given when prompted. The code is checked centrally to ensure it matches the document ID and is a valid and unused code, and if so, exchanges information with the end user's PC to enable the DRMX file to be decrypted and saved as a readable DRM file, which looks just like the original PDF file. Note that authorization codes are simply look-up codes, and do not have any encryption/decryption function

7. There are lots of checks and log files to make sure that as far as possible this all works smoothly. However, if there are questions or problems these can generally be sorted out very quickly. Facilities for this include:

(a) a file called PublishingHistory.csv on your PC somewhere like:
C:\DocumentsandSettings\username\Application Data\DrumlinSecurity\Drumlin which is very useful, as it contains lots of information about your publishing activities.... and
(b) there are several other files like this in the same location which are useful... such as the Drumlin.History file (can be opened with Notepad etc), AuthorisationHistory.xml and in the logs subdirectory, a full log file of usage of Drumlin and any issues or errors that arise
(c) Within Drumlin itself there are facilities on the Help menu to assist end users. These include the Welcome document, the links to online help and faqs, the Updates... facility for automated updating of their software, and the ABOUT form, which includes a SEND LOG FILE button... this latter facility automatically sends the user's log file and settings file to our support desk by email in case of problems that cannot easily be resolved
(d) users can double-click on a DRM or DRMX file to open it with Drumlin. If they do this with a DRMX file it will ask if they wish to authorize it - if they have done so already it will detect this. Users should not try and re-authorize a document as this will generally fail (because the code they have used will typically have been used already)
(e) user activity is logged on our central servers, so it is possible for use to identify end-user issues and actvities remotely. It is also possible for us to report on such activities to the relevant publsiher and to enable/disable documents and users if absolutely necessary

8. Web-based published document list: If you select the LOGIN page you can obtain a full list of the documents you have published. To log in you need your USERNAME (which is displayed on your Drumlin Help menu, About... form) and password. These were the ones you specified when you registered and are included on the Welcome registration email you were sent at the time. You can recover your password by entering your email address in the Recover password form and the password will be emailed to you.

9. Publishers often have special requirements. By default the free service provides the core software and service publishers require. However, there are many additional facilities and services available - Please contact us by email if you have any questions and look at our PDF-Publishing web site and the other pages on this web site for more information and advice
