PICS Presentation Talking Points
This is keyed to the set of slides prepared by NetScape and labelled
"DRAFT NOT FOR DISTRIBUTION 9/30/95"
- Title slide
- Founding members
- Table of contents: introduction, two useage scenarios (corresponding
to scenarios distributed in initial press release), technical
description of how selective access works. To be followed by
a separate presentation of detailed technical information and
possible demonstration.
- Introduction text: "The Internet, on line services, and
the World Wide Web, increase access to information which can be
both fun and educational.
- Parent and child using computer together. This is the ideal
way to make educational use of the wealth of information available
on the network. It is an exploratory learning experience, with
both the parent and child learning-by-doing.
- Child alone with computer. This is the problem we are trying
to solve: a child who inadvertently stumbles onto information
that is inappropriate (because of the child's age, the topic area,
the cost, or the necessary context and parental explanation).
Emphasize, perhaps, that "inappropriate" varies from
family to family as well as child to child; and the notion may
be that certain material is perfectly appropriate when viewed
with adult supervision, but not when viewed alone (example?).
- Solution: a system for content selection (with figure). The
basic idea is to interpose content selection software between
the child and the actual information when the parent isn't present.
The software may run on the child's computer or on the system
to which the computer connects to access the Internet (i.e. service
provider or on-line service).
- Today's systems compared to PICS. Today, there is one dominant
rating system for each kind of information (MPAA for movies, etc.).
The PICS approach is different. It assumes that any individual,
group, organization or corporation may provide a rating service
and it is up to the parent to choose the rating service that most
closely matches their own values. The PICS system itself is "values
neutral," in order to empower parents to express their own
values.
- Scenario 1, first screen, "Mom sets up system for 10-year
old son." Talking point: this is the first of two usage
scenarios we will show you today. The details of the interaction
are not part of PICS, but rather are left to a competitive market
place to work out. These scenarios are to show the basic steps
that a parent and child will see when installing and using PICS-compliant
software.
- "She begins by creating a new account." Talking
point: since each child is unique, the parent will establish an
account for the child to use by themselves. The choice of material
that is appropriate is left to the parent on a per-child basis.
- "She has a choice of service and levels. She chooses
..." Talking points: The parent has access to a number of
different rating services. The particular set of services that
are available will vary depending on what software the parent
is using and where the content selection software is run (on the
home PC or at an on-line service or access provider). Each service
has a description of the way it rates information, and the parent
chooses one or more rating services to use based on this information.
The actual screen shows a user interface that allows only one
service to be used for each child, but the user interfaces we
demonstrate later may allow more than one service to be used (so
that MPAA movie ratings can be combined with, say, local PTA ratings
of other information). Notice that for her son the mother has
chosen a policy of "Block Unrated Sites" meaning that
the son can only receive information that has been specifically
rated by the rating service she chose. Thus, if the rating service
has not yet had time to inspect the contents of a site, the son
will not be able to see any information from that site.
- "Later when her son turns on the computer to begin using
the Internet" Talking point: we now turn our attention from
the parent's experience when configuring the software to the son's
experience when using the software to explore the Internet on
his own.
- "He will sign on and enter his password before being
allowed access to the Internet" Talking point: this is how
the computer knows that it is the son who is using the computer.
For most computer users, this step is already one that they perform
today: in Windows/NT and Unix systems, the son must "log
in" before using the computer at all. For customers of commercial
Internet access providers or on-line services, the son would "log
in" before being allowed to use the service, for billing
purposes.
- "He might turn to a directory service" (I think
this title and content are changing) Talking point: this is
typical of today's use of the World Wide Web on the Internet.
The same basic idea applies to other services on the Internet
("net news" and "chat rooms"). PICS does
not address sending or receiving electronic mail.
- A visit to an approved site or page. Talking point: most
of the work of PICS is invisible to its users, just as most of
the work of the telephone or electric company is invisible. When
the son asks for information (in this case by clicking on a link
in the World Wide Web), the content selection software first obtains
a content label from the rating service that the mother
selected. If the label indicates that the information meets the
mother's pre-set criteria, then the content selection software
allows the access just as though the software hadn't been there
at all.
- A visit to a disapproved site or page. Talking point: when
the content label indicates that the information does not
meet the preset criteria, then access is blocked. PICS-compliant
software will signal a specific error, so that other parts of
the software system can decide how to reflect this to the user.
In our scenario, the user interface that the son is using presents
a screen showing that the access is blocked and gives him two
options.
- "If he really needs access he can ask his mom's permission."
Talking point: Continuing with our hypothetical user interface,
the son can leave a note for his mother explaining why this specific
bit of information is needed.
- "Later, when mom is home." Talking point: Since
the son was using the computer without supervision, he wasn't
allowed to see some information he had wanted. When the mother
next uses the computer, perhaps prompted by the son, she will
log in using her own account. This is probably the same account
she used to initially configure the system.
- "She can review the permision requests..." Talking
point: The system has kept track of all the information her children
asked permission to see, along with the reason they wanted to
see it. She can review the material herself and then decide whether
to allow a child to look at it. PICS does not mandate any particular
way of performing this review or of implementing these "parental
override" features; this is left to the competitive marketplace
of software vendors.
- "She can also set up a new account -- this time for her
14-year old daughter" Talking point: This is the same procedure
that was used to create the account for the younger son. Notice
that she has chosen a different rating system, and that this time
the mother has not chosen the "Block unrated sites"
option. This means that the daughter can access information unless
it has been specifically marked as inappropriate by the rating
service the mother has chosen. The mother apparently feels that
the daughter is mature enough to handle most kinds of information
on the Internet.
- "When her daughter turns on the computer to begin using
the Internet"
- "She will sign on & enter her password"
- Same initial visit
- Same second visit, but it isn't blocked for the daughter.
Talking point: because the mother chose a different set of content
selection criteria, the daughter is allowed to see some information
that the son found to be blocked.
- Third visit, blocked. Talking point: the content selection
isn't just turned off for the daughter. There is still information
that she must ask permission in order to see.
- "How selective access works" Text slide with bullets
- "Elements of the system" Flow diagram of system.
Talking points: recap the system. The parent configures the
content selection software. The child then uses the software
to access information. The software always requests a content
label before delivering information to the child. The label
can be delivered with the information, or from a separate server
run by the rating service. The child will not notice any difference.
Different rating services can provide labels for the same information,
and the labels may not be the same: the labels from a given service
reflect the values of the service provider.
