Digital rights management (DRM) is any procedure used by producers, publishers, and
retailers to embed technical controls on what customers can do with digital files – ebooks, videos on
DVDs, and other media. Especially, DRM programs are created both to allow attain and use of electronic
materials and to prohibit copying, sharing, reformatting or differently changing digital media. Such
limitations can range from “active” DRM, which marries ebooks towards a manufacturer of ereader to more “passive”
DRM, like watermarking a electronic file with the purchaser’s name and e-mail address.
Digital rights management (DRM) technological innovation are aimed at enhancing
the kinds and/or scope of handle that rights-holders can claim over their
intellectual property assets. In the wake of the Digital Millennium Copyright
Act’s (DMCA) ban on the circumvention of DRM technologies utilized to handle
copyrightable works, DRM limitations are now sponsored up with the force of legislation.
In essence, copyright owners currently incorporate the ability to create their private intellectual
property regime in computer code, protected in the knowledge that the DMCA will
back the routine with the force of legislation.
Copyright industries are attempting that digital rights management (DRM)
technologies will avoid infringement of commercially beneficial digital content, such as
music and videos. Such industries contain already persuaded legislatures to undertake wide
anti-circumvention rules to protect DRM from getting hacked, and courts include interpreted
these statutes even further broadly than legislators developed.
Digital Rights Management: Goals
To expand "analog" copyright secrets and techniques to the digital world.
Provide content Creators some manage over the use of the media they develop.
Different Generations of DRM:
Generation 1 (80's, early 90's)
Delicate Content wrapped in container record. (ex. zip, pgp (pretty good privacy) files)
Container is encrypted with a magic formula or password.
PGP often uses RSA & hash functions
Public-key encryption process.
Digital Signature offers authentication
hash function ensures that the contents have not been tampered with.
Generation 2
Native Documents encrypted within a native application (based on shared password)
Access Control Permissions added
disable print, copy
amount of views
Permissions the same for all users. File based.
Problem: shared passwords can be, well....shared.
Generation 3
AC Permissions can now range with each user
Every transaction generates a private key recognized only by the user who buys the content.
Problem: Permissions are impossible to change once the file has been sent to consumer.
Digital Rights Management is significant to creators and publishers of digital media
because it assists make sure revenue for their items. Since the introduction of personal computers, it
has turn out to be easy to copy digital media information in an endless number of instances and at the
identical time keeping the identical high quality point in every up coming reproduction. By handling
the trade, safety, checking, and monitoring of digital media, DRM assists publishers
minimize the unlawful flow of copyrighted works. Typically, a DRM process safeguards
intellectual property by both encrypting the information so that it can only be accessed through
approved customers or marking the content with a digital watermark, therefore the content can
not be freely dispersed.
