ITIS 1210 Introduction to Web-Based Information Systems Chapter 52 Parental Controls on the Internet
2
Introduction Advantage of the Internet Free flow of information Uncontrolled by any central agency or government Necessarily Some of that information Will be objectionable to someone Hate sites, pornography, political sites
3
Introduction Availability of information Leads to attempts to control that information Typical argument: The children should not be exposed to… Why children? Lack of judgment Unformed ideas that could be easily swayed
4
Introduction Number of efforts over the years to ban or control certain content Communications Decency Act of 1996 1: Attempted to regulate both indecency & obscenity 2: Operators of Internet services were not to be considered as publishers
5
CDA Most controversy was around indecency on the Internet FCC had controlled TV & radio for years Offensive speech restricted to certain times of the day (minors less likely to be exposed) 10 PM and 6 AM Violators could lose licenses & be fined Lenny Bruce George Carlin’s Seven Dirty Words
6
CDA Internet had only become public in 1992 Not covered under previous laws CDA was 1 st attempt to cover both Internet Cable TV Congress passed Feb 1, 1996 President Clinton signed into law Feb 8
7
CDA knowingly (A) uses an interactive computer service to send to a specific person or persons under 18 years of age, or (B) uses any interactive computer service to display in a manner available to a person under 18 years of age, any comment, request, suggestion, proposal, image, or other communication that, in context, depicts or describes, in terms patently offensive as measured by contemporary community standards, sexual or excretory activities or organs.
8
CDA June 1996 federal panel in PA overturned part of CDA Infringed on free speech rights of adults July 1996 federal court in NY overturned part protecting children as too broad June 1997 Supreme Court upheld PA decision Reno vs. American Civil Liberties Union
9
CDA Reno vs. ACLU: Indecency provisions of CDA were an unconstitutional abridgement of the First Amendment right to free speech because They did not permit parents to decide for themselves what material was acceptable for their children Extended to non-commercial speech, and Did not define "patently offensive," a term with no prior legal meaning
10
CDA 2003 Congress removed those portions of CDA that had been struck down Separate challenge by Nitke v. Gonzales in 2005 Nitke v. GonzalesNitke v. Gonzales Internet does not permit publishers to restrict destinations based on geography Act in effect restricted the entire Internet to the standards of the most restrictive community online
11
CDA Unfairly restricted her freedom of speech Struck down by NY federal court in 2005 Plaintiffs had not presented sufficient evidence Decision affirmed by Supreme Court in 2006
12
Other efforts Child Online Protection Act of 1998 Purpose was to protect minors from harmful sexual material on the Internet Required commercial distributors of “material harmful to minors” to restrict minors access to their sites
13
Other efforts Material harmful defined to mean By contemporary community standards Appealed to prurient interest Showed sexual acts or nudity (included topless women) In 1999 Third Circuit Court of Appeals struck down the law Using “community standards” was too broad
14
Other efforts Supreme Court found this reasoning insufficient & returned to lower court 2003, Third Circuit struck down again Finding hindered protected speech among adults 2004 Supreme Court upheld this ruling Noted that filtering software had improved As not taken into account
15
Other efforts March 2007 COPA struck down again Government permanently enjoined from enforcing it saying “… perhaps we do the minors of this country harm if First Amendment protections, which they will with age inherit fully, are chipped away in the name of their protection.”
16
Other efforts Children’s Internet Protection Act of 2000 Introduced by John McCain in 1999 Passed both houses in December 2000 Signed by President Clinton on Dec 21, 2000 Challenged in 2001 by American Library Assoc
17
Other efforts Previous challenges lost on 1 st Amendment grounds CIPA represented a change of strategy Federal government has no direct means of controlling local school/library boards HOWEVER, normally, telecommunications users pay a universal service tax Libraries receive an “e-rate” discount to purchase Internet access and computers
18
Other efforts CIPA required libraries and schools using these discounts to Purchase and use a “technology protection measure” On every computer connected to the Internet
19
Other efforts “ … a technology protection measure with respect to any of its computers with Internet access that protects against access through such computers to visual depictions that are obscene, child pornography, or harmful to minors … “
20
Other efforts Further, CIPA required that these measures be in effect during any use by minors For adults the same provisions applied except the harmful to minors part was deleted Measures could be disabled during use by an adult for research or other lawful purposes
21
Other efforts ALA challenged on grounds that CIPA required libraries to block access to constitutionally protected speech Enforcement involved removing federal funds intended to assist disadvantaged minorities “Digital Divide” No filtering software could accurately differentiate between illegal and protected speech on the Internet
22
Other efforts PA Court of Appeals agreed Supreme Court overturned Legal for federal government to include conditions imposed on receipt of funding Further, CIPA is constitutional if the library will unblock at an adult’s request Some libraries did choose to forego federal funding
23
Parental Controls On the Internet Is the answer in Legislation? Technology? Textbook suggests technology Software that permits parents to control access

Parental Controls On the Internet SurfWatch SurfWatch CyberPatrol Net Nanny Net Nanny Net Nanny Platform for Internet Content Selection PICS PICS
25
Parental Controls On the Internet AOL also filters content and blocks access PICS is working with industry to Develop standards to rate all Internet content Software could be developed to block access for children based on these suitability ratings Business also into the fray Lost productivity Liability for harassment, hostile workplace suits
26
How Parental Controls Work SurfWatch consists of a module that scans input from the Internet Intercepts it before it reaches the TCP/IP stack Checks URLS most likely to contain offensive content HTTP NNTP (news) FTP Gopher (distributed document search and retrieval network protocol designed for the Internet ) IRC
27
How Parental Controls Work Content from these URLS is isolated 1 st check: objectionable URLS Checked against a database of URLS from objectionable sites Content not permitted thru to TCP/IP stack User notified that site has been blocked
28
How Parental Controls Work 2 nd check: Pattern matching Words in URL indicative of offensive content Content not permitted thru to TCP/IP stack User notified that site has been blocked 3 rd check: PICS Information about content embedded in Web documents Content not permitted thru to TCP/IP stack User notified that site has been blocked
29
How Parental Controls Work If content passes all checks it is permitted through Process is very fast so user sees no delay Database updated monthly to keep up with new developments Businesses use SurfWatch on a server to protect their business network
30
Problems with SurfWatch Early efforts had some amusing moments 1996 White House page about Bill & Hillary, Al & Tipper Page named “couples.html” Renamed “principles.html” Archie R. Dykes Medical Library Library blocked from browsing their own site
