What are the problems COCOA solves?
There are four primary problems with displaying scanned page images that aren’t obvious: (1) Many copyright owners are concerned that even if security limited one person to looking at five pages per book, there are millions of people using “peer-to-peer” (P2P) file sharing programs, so if a handful of people look at five pages each, it only takes 40 people to download a 200 page book and share the assembled results, undetectable by Amazon. This can be done undetectably with as few as 10 people, and copyright owners are concerned this process may become automated. Amazon actually limits one person to viewing approximately 15% of the pages of one book, not five pages; Google blocks out approximately a random 15% of the pages of copyrighted books from view by anyone; nobody can see more than 85%. Some copyright owners are concerned that people have the ability to view 85% of a book from Google and the remaining 15% from Amazon. They worry this may become easier as more sites display pages
