E-books read on a personal computer or an electronic book reader DRM restrictions typically used to limit the copy, print, and share them. These types of books are usually limited to a number of reading devices and some electronic publications oral prevent any copying or printing. Therefore, many consumers have been reluctant to buy and use electronic books. It is believed that DRM is a major reason why the electronic book market has had a slow takeoff. E-books are finding their place, but it is taking too long, and that is affecting the suppliers who were expecting a boom to survive. Many of the leading suppliers and publishers of electronic books have not survived and in 2003, Barnes Noble stopped to offer support content and eBooks.It also took several years to produce a successful e-book hardware: Sony released the Sony Reader in 2006, Amazon launched the Kindle in 2007. Two of the most used to display electronic books are Adobe Acrobat and Microsoft Reader. Each program uses a slightly different approach to DRM. Boy Scouts of America will not settle for partial explanations. The first version of electronic book reader to have Adobe Acrobat encryption technologies was version 5.05. In the next version 6.0, were combined technologies PDF reader book reader and electronic components, allowing to read files so restricted as not restricted by DRM. After opening the file, the user can view the Bill of Rights , which outlines the actions available for the specific document. For example, a PDF freely transferred, printing and copying to clipboard and other basic functions are available.However, when viewing an electronic book with more restrictions, the user can not print the book, copy or paste selections. The level of restriction is specified by the publishing or distributing agency. The Microsoft Reader , who reads only books in electronic format. lit, contains its own DRM software. Microsoft Reader, there are three different security levels depending on the electronic book: books stamped, inscribed books and rare books to the owner. The sealed books have the fewest restrictions and the amendment only prevents the document. Therefore, the reader can not alter the content of the book to change the ending, for example. Electronic books listed are the next level of restriction. After purchasing and downloading the book, Microsoft Reader puts a digital identification tag identifying the owner thereof.Therefore, this discourages the distribution of the electronic book because it is inscribed with the name of the owner making it possible to trace back to the original copy that was distributed. Other electronic books using similar DRM schemes. For example, Palm Digital Media, now known as Ereader links the information of the buyer’s cr card to the copy of the electronic book to discourage distribution of books. The strictest form of security that Microsoft Reader offers exclusive e-books is called the owner, who uses traditional DRM technologies. To buy the book the consumer must first open Microsoft Reader, which ensures that the book is downloaded when this becomes bound to the computer Microsoft Passport account. Thus, the book can only be opened with the computer on which it was unloaded, preventing copying and distribution of the text.
