Potential copyright violation detected pdf




















Here's one such message. When attempting to do so, they get error "There was an error contacting the server or the server's response could not be decoded. Please check your internet connection.

If the error persists please contact the publisher and present the text of this message". Somewhat parenthetically, I'd like to point out the extremely professional structure of this question: the exact text of the error is presented, the questioner seems to have already determined the cause of the problem firewall blocking access so asks for data to verify that assumption.

For a tech-support person, interactions like this one are a real pleasure. This server is part of our Toolkit evaluation package, and implements a very simple PermissionServer script, without SSL, and contains document examples that don't require any authentication.

Finally, recently enhanced, there is the screen capture protection option. If you have any questions regarding this blog item, do please contact us or add your own comment to this entry. But as they go on to say:. Any unlawful copy of their book or journal, in paper or electronic form, affects their business as much as the theft of the same work as a book in a shop.

Any unlawful copying amounts to a misappropriation of their property. Consequently, copyright laws generally sanction this theft, under civil and sometimes also under criminal law, just like the theft of tangible property. Unfortunately, copyright infringement is not as easy to detect as the theft of physical goods, particularly not in the electronic age where electronic files can be created and widely spread within short time periods.

This renders the enforcement of copyright particularly difficult, and makes awareness-raising particularly important. Here is an example — the website bookzz.

There were 28 hits — the first two links indicated that the pursuit of the hosting site by the legal owner has resulted in the download links being deleted — but many others on this site remain available, with downloads offered for the Life of Pi in ePUB, HTML and Text formats as entry 21 below shows.

Clearly breaches of copyright and hard to eliminate. So what do you do if your publications has been pirated, or your suspect this to be the case? Maybe you have issued them with limited security e. The answer is a three-fold approach:. Improve the level of protection you apply to your publications; and.

Minimize the commercial impact of piracy on your business, if possible. We look briefly at these elements below, but please investigate the links provided for a fuller picture of the options available. Pursuing the pirates can be a difficult and potentially expensive process, but specialist law enforcement units and commercial and trade bodies can help a lot.

Then there are working groups, seminars and even summits on how to tackle piracy see for example the annual Anti-Piracy and Content Protection Summit , Finally there are commercial providers of anti-piracy services stopping the abuse of your copyright such as Digimarc Guardian and Rightscorp. These latter organizations take a pro-active approach to copyright abuse, seeking out websites and services that distribute material illegally and implementing a multi-step approach to removing the links and identifying the perpetrators.

The second part of the process is to try and improve the protection provided to your PDF publications. One key mechanism is to use a combination of static and dynamic intelligent watermarking to make any attempt to copy your material extremely difficult without inclusion of these watermarks.

Of particular value are watermarks that uniquely identify the end user, as this provides a means for directly pursuing the individual or corporate body responsible. Our blog article on watermarking is a useful starting point.

A strong DRM is also vital Drumlin for example, but there are quite a few to investigate , but that is not always possible because distribution channels like Amazon and Apple have their own, proprietary DRMs. For those not dependent on such channels a powerful DRM combined with watermarking and strong Warning Notices is the preferred option. And where proprietary material is provided to Corporates, make it clear in your contracts that the Corporate will be held liable for any copyright abuse by their staff — which will encourage them to police their own staff and advise them of the sanctions available if such actions occur.

If your publications are commercial, making the access to the material fast, simple but secure, and making the per copy cost reasonable depending on volumes and content of course may well help — this is how the big players in the ebook world, video and audio-media distributors, and games world have tackled the problem — basically they accept that piracy will occur but seek to make piracy pointless — worthy of consideration, always assuming that your business model can support this approach!

User-independent authorization systems : these are systems where files are downloaded and are authorized for offline usage by either device identification, which requires prior registration of the device, or by entry of an authorization code that is checked on a central DRM system does not require prior registration.

Note that with this second approach there is little or no requirement for central service management as the process is automated.

In practice these systems require user registration in order to handle the financial transactions when ebooks are purchased, so are actually device- and user-based. Note that the great majority of PCs, unlike most other devices, do not have a consistent and uniquely identifiable deviceID.

An example of an authorization system with no prior user or device registration is the Drumlin DRM service with Javelin as the end-user reader.

A diagram showing the key elements of this process is available here. Drumlin has facilities that provide centralized permissioning — please contact us if you want to know more about this option. Online-based systems: approaches 1 and 2 assume the files are to be downloaded and read offline — no regular host connectivity is required after the initial stage of downloading and enabling.

An alternative is a hosted service where the files are kept centrally and displayed via a web browser. Note that this option is simple to manage because the files are held centrally, and if required access can be controlled for entire groups of users with usage tracking rather than at the individual customer level.

Google Drive limits uploads to 2Mb. This hole may become patched in later versions. Install Ghostscript and GSView. Change the extension of the PDF file to.

Resulting PDF is free of restrictions, including restrictions on printing. Visit the PDF Unlocker web site. Select the PDF file to unlock and let it upload to the server. Click the Download button to obtain the unlocked PDF file. Various "unlocker" programs exist on the Internet. Search for PDF password recovery. Proprietary software alert. Caveat emptor buyer beware. These programs do not really unlock 3rd party JS plugins. Some demos available online even spend a minute conducting a fake test that pretends to open the file.

They say the PDF can be unlocked, but then, after purchase, these programs unlock file passwords only. They do not actually work against 3rd party JS server passwords.

How could they? They would have to hack the server to do that. While server hacking is certainly possible, it is beyond the scope of this howto. Many of these techniques involve opening a PDF file from within Adobe Reader , allowing JavaScript to unlock it, and then printing it to file.

There are many ways to print to PostScript or PDF, and literally hundreds of ways to break the restrictions on the resulting files. Those earlier PostScript drivers have been deprecated, but older versions of Ghostscript still provide them. Some PDFs won't allow printing or saving, and some of them are timed access. If it can be viewed, it can be screen captured. Simply open it up, preferably on a large desktop that can be tilted to where it shows the whole page, and take a screenshot of each page.

It might be a good idea to empty out the screenshots folder first! Hopefully this will create a series of numbered images there.

Then use something like imagemagick to convert the series of numbered images into a PDF file. The result might be great, or not so pretty depending on the desktop resolution, page dimensions, and other factors. The document can not be text searched because it is composed out of images, but there are programs that can optically recognize the text, and create a searchable index for PDF files.

Hope this helps! What are PDF Files? Why Cracking is Necessary If somebody creates a PDF and then forgets the password, they need some way to recover the lost password.
