Copyright HistoryBook Curse:
“For him that stealeth, or borroweth and returneth not, this book from its owner, let it change into a serpent in his hand and rend him. Let him be struck with palsy, and all his members blasted. Let him languish in pain crying out for mercy, & let there be no surcease to his agony till he sing in dissolution. Let bookworms gnaw his entrails ... when at last he goeth to his final punishment, let the flames of Hell consume him forever.”
And you thought our plagiarism punishments were harsh …

Copyright HistoryPrinting Press − Johannes Gutenberg − 1447
Similar printing technology
known in Korea and China
by c. 1234.

The Statute of AnneShort title: Copyright Act 1709
Long title: "An Act for the Encouragement of Learning, by vesting the Copies of Printed Books in the Authors or purchasers of such Copies, during the Times therein mentioned’’
• Generally considered to be the first fully-fledged copyright law. • Named after Queen Anne, during whose reign it was enacted.• Replaced the monopoly enjoyed by the Stationers’ Company (The
Worshipful Company of Stationers and Newspaper Makers, www.stationers.org).• Company members would buy manuscripts from authors.
Once purchased, they have perpetual monopoly on the printing of the work Authors themselves were excluded from membership in the company Could not therefore legally self-publish Given no royalties for books that sold well.

The Statute of AnneThe statute of Anne vests authors rather than printers with the
monopoly on the reproduction of their works.
Time Limits Books already printed:
Copyright owner has exclusive right of publishing it for 21 years. Works not yet published:
Exclusive right to publish for 14 years from the time of first publication Right could be extended by an author for another 14 years.
Territorial loopholes Did not extend to all British territories Many reprints of British copyright works were consequently issued both in
Ireland and in North American colonies
7(#total)
Other IssuesOrphaned works Difficult or impossible to contact the copyright holder Causes difficulty for anybody seeking to use/build on work
Moral rights Not to have the work altered or destroyed without consent. Right to be attributed as the author of the work. Monty Python (comedy) relied on moral rights in 1975:
Legal proceedings against American TV network ABC for airing re-edited versions of Monty Python's Flying Circus.
Provisions for the handicapped In U.S. provision for reproduction of material for the blind or other
persons with disabilities. Permits the reproduction in Braille, audio. electronic, Web-Braille, etc.

Arms Race? Law versus Technology
• Before the Printing Press was invented it was to costly “pirate” someone else’s work.
• Printing press allows cheap copies.• Licensing Act in 1662 in England which protected
printers against piracy.• Laws strengthened over time to catch up with
technology – home recording etc.
• If law stronger then protection stronger.• If technology stronger then protection weaker
IP creators unable to claim economic benefitLarge part of incentive to create lostBad for society

What is P2P?Peer-to-peer (P2P) computing or networking is a distributed application
architecture that partitions tasks or work loads between peers. Peers are equally privileged, equipotent participants in the application. They are said to form a peer-to-peer network of nodes. (See Wikipedia for a good article on Peer-to-Peer (p2p) architectures.)
Peer-2-Peer Internet technology Largely used for illegal file-sharing Widespread sharing of files, music, etc Growing problem as broadband uptake is increasing
Peer to Peer file sharing – e.g., Napster, gnutella, … Many forms of p2p
BitTorrent Peer-2-Mail (exploits webmail, more secure) Instant Messaging Services, e.g. MSN Messenger
Characteristics: User interface loads outside of Web browser
(Standard p2p client) User computers can act as clients and servers
Audio Galaxy, Imesh or Morpheus MusicCity Financed by adware/spyware (removal - lavasoft.de)

BitTorrent• Has rapidly grown into very powerful & popular p2p technology
Greater speeds
Ease of uploading files
Easier to manage downloads
Downloading larger files possible(typical movie is 700MB in DivX)
• No search, download ‘.torrent files’ then run on BT client
• In 2006, 53% p2p traffic is BitTorrent …
• In 2006, 30% of all internet traffic …

Effects• CD sales have fallen since 1999 when Napster started
P2P craze• Between 2000 and 2002 CD sales fell by 139 million
copies• Musicland: major US music retailer bought by BestBuy in
2000 for $696 million, sold for $1 in 2003• iTunes is all-conquering … imitators pile in • Recent years have seen major concerns from the music
industry• Digital Economy Act in the UK …

Remedies
Lawsuits Recording Industry Association of
America (RIAA) issued thousands Similar to book curse – fear - Article P2P illegal file-sharing is hard to govern since no specific
laws
BitTorrent tracker sites closure Some sites closed – but new ones spring up
Media Defender Developed technologies where copyright owners can plant
decoy files to annoy downloaders Downloaders working for less than minimum wage
Overpeer Discourages p2p file-sharing by using advertisements Provide information on where to buy the CD, movie, etc
and even provide samples
14(#total)
Arguments for P2PLegitimate uses of p2p
NASA – to distribute cache on BitTorrentFree software and open source software
iTunes & NapsterOnline music download stores
Selling music online Reduced overheads costs Reduced production costs No distribution, packaging, etc Redundancies: Less staff needed
15(#total)
Summary97-98% of traffic in P2P is unlawful
60% internet traffic is P2P
Every month on average 3.6 billion music downloads
Many people losing out
It’s hard to combat

Are New Laws Required to Protect Copyright
(in Light of Digital Media Internet Etc) or Have Some Laws Gone Too Far?
– Brian Byrne

World Intellectual Property Organization (WIPO)
The World World Intellectual Property Organization is a United Nations agency.
Setup in 1967 to
“encourage creative activity, to promote the protection of intellectual
property throughout the world”Currently 182 member states are a member of the
WIPO.
18(#total)
EU Copyright Directive (EUCD); Digital Millennium Copyright Act (DMCA)
Member states signed The World Intellectual Property Organization (WIPO) treaty in 1996.
Signing countries promised to implement these treaties in law .
So the DMCA is the American implementation of the WIPO treaty.
There is a European version called the European Union Copyright Directive (EUCD). Very similar.
The DMCA Covers many areas: We focus on the “Anti Circumvention” provisions of the
law.
19(#total)
Summary of Anti Circumvention Provisions
Prohibits
1. The act of circumventing technological protection systems.
2. Manufacture of devices / software that allow the circumvention of access control or copy controls.
3. Publishing methods to circumvent a protection system. (e.g., publishing source code).
Allows
1. Circumvention/cracking for research purposes.
2. In certain circumstances non profit organizations and libraries can circumvent.
20(#total)
Why was the DMCA requiredThe circumvention provisions of the act where mainly
intended to stop “black box” descramblers used for free cable TV.
Pressure from entertainment industry.
“Arms race” between technology and Intellectual Property law.
21(#total)
Do we need these new laws?Computers make perfect and cheap copies of digital
media.
Its difficult to catch pirates because of anonymous nature of the internet.
Cyberspace offers the worst of both worlds for IP owners
“place where the ability to copy could not be better and where the protection of law could not be worse “
(Lessig).
22(#total)
However … • Technology gives control to IP owners.• Technology can control how we can consume / use IP.• User has lost traditional rights (fair use, read a book as many
times as you like, lend it to a friend, sell it …)• But can’t do this with copy protected electronic books – O’Reilly
Safari book shelf• Napster subscription based music – stops working when
subscription ends.• DVDs region encoded. (Bought in another country can’t use on
your machine).
Perfect control to IP owners. In the past organisations were only given “exclusive rights” for
limited time If no time limit on monopoly – no incentive to improve
23(#total)
No balance of power between user and IP owner
The DMCA and protection technology give total control to IP owner.
No provision to preserve the traditional rights of consumers.
If a user wants to regain these rights they must break the law. (circumvent)

Breaking the Law: Circumvention
DVDs are encrypted by the Content Scrambling System (CSS).
Technically, it is illegal to watch a DVD on a Linux system (all DVD players must apply for a licence). (DMCA/EUCD)
Motion Picture Association of America (MPAA) refused to grant a license to the open source project LiVid - Jon Lech Johansen cracked it
Jon Lech Johansen (aka DVD Jon) tried and retried in Norway for his involvement in writing DeCSS, acquitted both times.
25(#total)
Is the DMCA Suppressing Free Speech?
Many websites published DeCSS – MPAA wanted to suppress it and sent subpoenas to the web sites saying they were contravening DMCA
The “Hacker magazine” 2600 for refusing to remove DECSS source code from its website (circumvents DVD encryption system).
They were Aided by the Electronic Frontier Foundation (EFF) – but stopped short of US supreme court
Legitimate uses for DeCSS Fast forward / Remove advertisements Remove region encoding Time Warner: Local laws impose censorship regulations Aids governments around the world in censoring the media their residents
can view DMCA makes it a crime punishable in US to circumvent censorship laws of
dictatorships worldwide

Is the DMCA Suppressing Free Speech?
Security text book author states he is afraid of printing methods for circumventing DVD encryption.

Is the DMCA Suppressing Free Speech?
Dmitry Sklyarov a Russian PhD student was arrested in California after giving a presentation on eBook's Security protection.
Circumvented Adobe’s eBook -> PDF Only worked with legally purchased copies
Legitimate uses Also allowed illegal copying
Crow bar
Is it illegal to own or buy one? Many legitimate uses ‘Going equipped to steal’ is an offence in UK law

Researchers Scared of Court Cases
Edward Felton a Princeton University professor –
$10,000 challenge to remove Secure Digital Music Initiative (SDMI) watermarks
Published paper – legal action threatened but judge dismissed case
Institute of Electrical and Electronics Engineers (IEEE) introduced a policy “requiring all authors to indemnify IEEE for any liabilities incurred should a submission result in legal action under the DCMA”
After outcry – removed clause
30(#total)
Conclusion
• Copyright law needed to “to promote the progress of science and useful arts”.
• The DMCA is being misused:• Suppresses free speech.• Stifles innovation – researchers scared to publish
work.• Denies traditional rights such as fair use. And requires
us to break law to reclaim those rights.

Digital Object Identifiers
DOIs – handle, track content
Persistently associate metadata with digital objects
Easily access by prefixing http://dx.doi.org
XML used to store meta data
Drawback - hard to find DOI for some content
no sesarch facility
Good for static IPRs
Poor for dynamic IPRs and offline content – need regular updates
39(#total)
The Way Forward?
DOIs provide a good framework for identifying some types of IPR
Need:
Search
Data integration and government cooperation
Contract management integration – automatic updates
Always going to have to employ different methods
