10. Four common stages :
 Packaging is when DRM encryption keys are built right into the
software, the music file, or the movie file.
 Distribution is when DRM-encrypted files are delivered to the
customers. This is usually through web server downloads, CD's/DVD's,
or via files emailed to the customers.
 License Serving is where specialized servers authenticate legitimate
users through an Internet connection, and allow them to access the
DRM files. Simultaneously, license servers lock up the files when
illegitimate users try to open or copy the files.
 License Acquisition is where legitimate customers acquire their
encryption keys so they can unlock their files.

2
Package with
appropriate
security

12.  You are using a WMA file;
 You need specific software or specific music player hardware to play the
file;
 You are limited to how many times you can download;
 You are limited in number of hours/days you can download;
 The number of different computers you can download to is limited;
 The number of times you can burn a CD is limited;
 You need a special password and/or logon ID before you can play the file;
 You need to reply to confirmation emails before you can play the file;
 In some instances, AAC files have DRM locks.
 How to identify DRM :-

13.  Game coNsoles (Nintendo, Sony PlayStation, …)
 Microsoft software (Genuine certificate verification)
 Trial use of a software for a limited period of time
 Online registration to activate the software

14. Apple’s Fair Play Technology
 Restricts playing, recording, sharing of files
 Allows media to be shared among devices
 Allows others to listen to (but not copy) music
 Can burn audio CD, eliminates DRM protection
How it works (overview)
iTunes uses encrypted MP4 audio files
Acquire decryption key by trying to play song
 player generates a unique ID, sends ID to iTunes server
 if not over authorization limit, server sends decryption key.
 Decryption key is encrypted in iTunes to prevent transfer to another
machine
