Definitions

  • This invention relates to controlling access to content.
  • the Internet and other computer networks can provide users with a wealth of information on almost any topic. Some of this information, however, includes material that may be offensive and/or unsuitable for children.
  • Organizations such as the Recreational Software Advisory Council (RSAC) have proposed rating schemes that provide users with information about the nature of content offered by different network sites.
  • the RSAC rating scheme defines categories for describing the violence, nudity, sex, and offensive language included in content.
  • Different vendors such as MICROSOFT have integrated the RSAC scheme into their software to enable users to control the content displayed. For example, a parent may configure a browser to deny access to any content having a RSAC nudity rating above "revealing attire.” These parental controls enable parents to prevent their children from viewing mature subject matter.
  • controlling access to requested content includes accessing information describing requested content, accessing information describing at least one regulation that is related to the requested content and to geographical information, and determining whether the content information satisfies the regulation(s).
  • Embodiments may include one or more of the following features. For example, access to the requested content may be denied if the content information is determined not to satisfy the applicable regulation(s), and may be permitted if the content information is determined to satisfy the applicable regulation(s).
  • the information describing the content may be content ratings.
  • the content ratings may include data corresponding to one or more of violence, nudity, sex, and language.
  • the content ratings may be substantially in accordance with the Recreational Software Advisory Council (RSAC) ratings scheme.
  • Accessing information describing the content may include accessing a database that includes information for different content. Accessing information may also include accessing content information in a response to the content request.
  • One or more regulations related to the requested content may be determined. This may include inferring the citizenship of a user that requested the content, for example, by accessing the user's billing address and/or determining an access number used by the user.
  • the regulation may be a national regulation, an international regulation, and/or a local regulation such as a law, an ordinance, a rule, a treaty, a proclamation, or an edict.
  • the regulation may be a regulation that applies to citizens within a jurisdiction, to citizens outside a jurisdiction, and/or to non-citizens within a jurisdiction.
  • the content can include text, graphics, animations, sound, video, and instructions.
  • an indication that access has been denied may be provided if the content does not satisfy the applicable regulation(s).
  • access to requested content available on the Internet is controlled by receiving a request for content, accessing content ratings describing the requested content, accessing information describing at least one applicable regulation that is related to geographical information concerning the requestor, determining whether the content information satisfies the regulation(s), denying access to the requested content if the content information is determined not to satisfy the regulation(s), and permitting access to the requested content if the content information is determined to satisfy the regulation(s).
  • the invention may be implemented as a computer program, disposed on a computer-readable medium, for controlling access to requested content.
  • Advantages may include one or more of the following.
  • a system can protect both an end-user and a common carrier from liability for viewing or transmitting prohibited content.
  • use of the system to self- regulate the content offered by the carrier can make the carrier more appealing to governments, for example, when seeking permission to operate in a jurisdiction.
  • the system can be incorporated easily into software that already provides parental controls to thereby take advantage of the ratings already determined for a large body of content.
  • the proxy can prevent users from disabling the controls, further protecting both the users and the common carrier.
  • FIG. 1 is a screenshot of a list of URLs (Universal Resource Locators) provided by a search engine.
  • FIG. 2 is a screenshot of a display indicating that access to requested content has been denied based on applicable regulations.
  • URLs Universal Resource Locators
  • FIG. 3 is a flowchart of a process for controlling access to requested content based on one or more regulations.
  • FIG. 4 is a table of categories and category levels for describing content.
  • FIG. 5 is a diagram of data describing content.
  • FIG. 6 is a flowchart of a process for determining regulations that apply to a content request.
  • FIG. 7 is a table of regulations.
  • FIG. 8 is a diagram of a proxy that processes client requests for content.
  • FIG. 9 is a diagram of a client that denies access to requested content based on one or more regulations.
  • FIGS. 1 and 2 illustrate a system that denies a user access to content that does not comply with applicable regulations.
  • Such content can include text, graphics, animations, video, sound, and instructions.
  • the content can be embodied in a wide variety of formats such as HTML (HyperText Markup Language), XML (Extensible Markup Language), or MPEG (Moving Pictures Experts Group).
  • HTML HyperText Markup Language
  • XML Extensible Markup Language
  • MPEG Motion Pictures Experts Group
  • URL 100 corresponds to a resource that provides content related to nude beaches.
  • FIG. 2 when a Saudi Arabian citizen attempts to retrieve the nude beach URL 100 content from the network site, the system denies access based on Saudi Arabian regulations that prohibit Saudi Arabian citizens from viewing content that includes nudity. The system provides a display explaining that regulations (e.g., laws, treaties, rules, ordinances, proclamations, or edicts) caused the system to deny access.
  • regulations e.g., laws, treaties, rules, ordinances, proclamations, or edicts
  • the system protects from liability both the citizen attempting to access the content and the carrier transmitting the content. Additionally, even in countries where carriers do not have a duty to monitor content, the use of the system by a carrier to self- regulate the content that the carrier provides can increase the carrier's appeal to a government, for example, when the carrier seeks permission to provide services within a country.
  • FIG. 3 illustrates a process 102 for controlling access to content based on regulations.
  • Process 102 includes determining the nature (e.g., the degree of violence or nudity) of the requested content (step 104), determining regulations (e.g., state, county, national, or international regulations) that apply to the request (step 106), comparing the nature of the requested content with the restrictions imposed by the applicable regulations (step 108), providing access to the content if the content meets the applicable regulations (step 110), and denying access to the content 112, in whole or in part, if the content fails to meet these regulations (step 112).
  • the process 102 may determine the nature of the requested content as described with respect to FIGS. 4 and 5, may impute or obtain the nationality of the requesting user, and may use the nationality to access encoded representations of that nation's regulations, as described with respect to FIGS. 6 and 7.
  • step 104 may include inferring the nature of the requested content from search terms, from metatags associated with search results, from lists or services maintained to categorize requests, or otherwise.
  • the Recreational Software Advisory Council (RSAC) rating scheme 120 includes categories 122- 128 (e.g., violence, nudity, sex, and language) and category levels 130-138 (e.g., zero to four). The scheme can be used to describe content by assigning the content a level 130-138 for each category 122-128.
  • RRC Remote Software Advisory Council
  • the network site shown as "www.sex.com" is rated in accordance with the RSAC scheme including level data for each RSAC category.
  • the rating shown indicates that the network site 142 does not portray any violence 144 (i.e., level “0” 138 of the violence category 122), but does include “provocative displays” 146 (i.e., level "4" 130 of the nudity category 124), “explicit sexual acts” 148 (e.g., level "4" 130 of the sex category 126), and
  • vulgar language 150 e.g., level “4" 130 of the language category 128,.
  • One or more additional categories may be available for other forms of rating.
  • the content need not be described in accordance with the RSAC ratings scheme or any other existing ratings scheme.
  • the ratings scheme used may depend on the common carrier's preference. The use of an established scheme, however, enables the system to use a large existing body of content ratings.
  • Using the RSAC scheme also permits easy modification of software that implements parental controls to also implement regulation- based controls. Preferably, software that enables a user to disable parental controls does not permit the user to disable regulation-based controls.
  • Content rating can be performed in many different ways. For example, an organization may have a human operator retrieve information from different network resources and rate the retrieved information. Alternatively, a program may examine content and automatically determine ratings based on the inclusion of information (e.g., words) associated with different categories.
  • Content ratings can be collected and stored in databases. Such databases can be centralized or distributed across different computers. Alternatively, content ratings can be stored at network sites providing the rated content. These sites can transmit the ratings along with the requested content and let the client or an intervening agent process the ratings.
  • determining applicable regulations can include determining the citizenship of a user, for example, by examining a user's billing address or by accessing data such as a user's self-reported citizenship (step 1 14).
  • Determining applicable regulations 106 can also or alternatively include determining the current location of a user, for example, by determining the access number dialed by a user to connect to a service provider (step 116). Based on this information, the system can determine the applicable regulation(s) by, for example, consulting a look-up table (step 118). Referring to FIG. 7, an exemplary look-up table 129 that is used, e.g., in step
  • the table 118 of FIG. 6, stores encoded representations of regulations of different national, international, and local entities.
  • the table includes regulations encoded in accordance with the RSAC ratings scheme.
  • the table expresses a regulation as the maximum level, or threshold, of permissible content in each of the RSAC categories 160- 168. If a content's category rating exceeds a regulation's category threshold, the content does not meet the regulation. For example, a regulation specifying that content having more than "moderate expletives" (level 2 of the RSAC language category) effectively prohibits access to content including "strong language or hate speech" (level 3 of the RSAC language category). The regulation would also prohibit access to "crude or vulgar language" (level 4 of the RSAC language category).
  • the table 129 can include multiple rows for each jurisdiction to encode different types of regulations (e.g., 170-178).
  • the table 129 can store regulations that independently govern citizens requesting content within a jurisdiction (e.g., 170) and citizens requesting the content outside the jurisdiction (e.g., 172).
  • other regulations can independently regulate access by non-citizens requesting content within the jurisdiction (e.g., 174) and non-citizens requesting content outside the jurisdiction (not shown).
  • the system can determine whether to deny or grant access to the content. For example, if a U.S. citizen requested content from "www.sex.com" (FIG. 5) from a computer in the U.S., the system would deny access because the level of sex in the requested content (i.e., level "4" in FIG. 5) exceeds the maximum level of sex 138 (i.e., level "3" in FIG. 7) permitted in the United States. In this example, if the U.S. citizen made the same request while in another country, the U.S. regulations 146 for citizens abroad would not result in denied access because the level of sex permitted in the other country is "4", the same as the level of sex in the requested content.
  • Regulations of more than one jurisdiction or entity may apply to a request for content.
  • the system can process the different regulations to ensure the content satisfies all applicable regulations. For example, two regulations 176, 178 may apply to a German citizen traveling to Japan. The system ensures that requested content satisfies both regulations 176, 178. If the traveler requested the content of FIG. 6, the system would deny access either on the basis that such access would violate Japan's regulations because the content includes nudity more excessive than "partial nudity" (e.g., level "2" of the nudity category 162) or on the basis that such access would violate Germany's regulations because the content may include hate speech (e.g., content more excessive than level "2" of the language category 166).
  • the techniques described above can be incorporated into a proxy 184 or other intermediate agent that processes content requests.
  • the techniques can be offered by an Internet Service Provider.
  • a proxy 184 processes content requests received from a client 180 via a modem 182 or other communication device by forwarding content requests to content sources 186 (e.g., Internet Web-servers) and returning the responses of the content source 186.
  • content sources 186 e.g., Internet Web-servers
  • the different elements can reside in different jurisdictions 188, 190.
  • the proxy 184 can ensure that information that is returned in response to a content request complies with applicable regulations.
  • the user may be denied the ability to disable the controls, further protecting both the user and the common carrier.
  • the regulation instructions 192 can access regulation data 194 (e.g., the table of FIG. 7), user data such as billing information 196, and content ratings 198 data or instructions.
  • the content ratings 198 may include a table that collects ratings of content available from different content sources 186, e.g., a table including several records such as that shown by FIG. 5.
  • the proxy 184 can determine regulations applicable to the requesting user based, for example, on the user's citizenship or access location and the ratings corresponding to the requested content in the content ratings data 198. If the content does not comply with applicable regulations, the proxy 184 can return information (e.g., HTML instructions and data) indicating that the proxy 184 is not transmitting the requested content due to content regulations.
  • regulations applicable to the requesting user based, for example, on the user's citizenship or access location and the ratings corresponding to the requested content in the content ratings data 198. If the content does not comply with applicable regulations, the proxy 184 can return information (e.g., HTML instructions and data) indicating that the proxy 184 is not transmitting the requested content due to content regulations.
  • FIG. 8 is merely illustrative and other embodiments could implement the system differently or could add or omit elements.
  • the proxy 184 could receive content ratings in data supplied by a content source 186 responding to a request.
  • the system could dynamically determine the nature of requested content using software that examines the content. Further, the system need not store user data 196, but could instead infer citizenship information based on the access location of the modem 182 or other communication device used by the client 180.
  • the techniques described above are not limited to use in a proxy or other intermediate agent, but instead could reside in the client 180.
  • the regulation instructions 192 access regulation data 194 and user data 196.
  • the regulation data 194 may or may not be much more limited in scope or volume than the comprehensive list of regulations shown in FIG. 7.
  • an American client may only include regulations that apply to U.S. citizens.
  • user data 196 need not be stored, but can be dynamically obtained, for example, by querying an operating system registry.
  • the regulation instructions 192 can prevent presentation of information that does not comply with applicable regulations.
  • the methods and techniques described here may be implemented in digital electronic circuitry, or in computer hardware, firmware, software, or in combinations of them.
