Introduction
● We live in two worlds: physical and digital
● We want to respect talented people
● We want to respect customers’ rights

Fair Use: Customers’ rights
● Four factors
● Unsolvable by machines

DRM: Talented people’s work
● Wide scope● Examples● DMCA● Standards
Scenario
• Alice has purchased an Chemistry ebook that was recommended by her course tutor
• She travels to school on the bus and may wish to read the ebook on a pda or other such portable device.
• Later at school, she may want to quickly refer to some of the diagrams found in the ebook in more detail on a PC with a large screen.
Scenario
• At home, while writing a report she may wish to cross check some of her own notes with the ebook again, but this time using a laptop.
• Still at home, a friend on her community network has asked her a Chemistry question which she would like to answer in part by sharing some information from her ebook.
• After the course examinations, the student would like to transfer the ownership of the ebook to her younger brother.

Conclusion
● Fair use is based on physical availability of an item
● Critics claim that is imposible to solve the problem
● Using social networks is an attempt to make it more consumer friendly whilst leaving enough control for content distributors

Future work
● Continue research in FRM project
● Investigate related aspects of the law
● Target eLearning environments
