E-Books that are read on the personal computers or e-book readers both use DRM technology. The use is meant to prevent copying, printing and sharing of E-books. These E-books are typically limited to a host of reading devices. Copying or printing are both prevented by some e-book writers. These restrictions prompt many readers to avoid reading and using e-books. Yet the use of DRM is essential for the protection of your intellectual properties and e-book comprises one of the largest components of intellectual properties.
Gradually the e-books are taking their place in the world of web. Therefore the e-book publishers have now taken up ways and means to prevent the copying and hacking of the intellectual properties. It has taken quite sometimes to bring out successful software for preventing such copying of e-book.
Some of the programs used on the web are the Adobe Acrobat and Microsoft Reader. Both these programs use digital rights management system. The technology now used in both these software enable you to read both DRM restricted and free E-books. However, you will not be able to print copy or paste the selections.
Document protection with DRM
Two formats are mostly used named the E-DRM and ERM to control and regulate access to documents. You can ensure document security, pdf document security, protect AutoCAD files, and also various other documents like emails and web pages. Here the keyword is not the control of the consumer activities but implying the restrictions with the documents themselves.
E-DRM today is more popularly known as IRM or the Information Rights Management. It is generally aimed at preventing any unauthorized use of documents that are classified or proprietary. It typically amalgamates with any of the content management software popularly known as DRM systems.
Many noted organizations such as the British Library has been using DRM to secure their documents and protect the web contents. At the same time it ensures secured electronic delivery services that permits worldwide access to numerous consumers and users. The advantage is that the documents that were only available to limited persons who were actually visiting the library in the past is now available for general uses.
Use of digital watermarks
A new dimension has been added to the document protections with the DRM technology with the introduction of digital watermarks. They are normally added during the production or at the time of distribution of the documents. These are stegano-graphically embedded on the audio data or the video data.
Various types of watermarks can be used to protect your document to ensure the pdf document security or web content security. The main purposes for which such water mark is used can be –
* Recording the mark for identifying the rightful owner.
* Recording the mark for identifying the rightful distributor.
* Recording of the distribution links and chains.
* Recording of identification of the consumer.
Neither watermarks nor all the present DRM mechanisms are self contained systems. Some of them include the watermark only act as the basic components of the system as a whole. The end objective remains identical in each case though. It is the protection of your intellectual properties in form of document or any other data or information from possible pilferage.
