While described in conjunction with these embodiments, it will be understood that they are not intended to limit the disclosure to these embodiments. On the contrary, the disclosure is intended to cover alternatives, modifications and equivalents, which may be included within the spirit and scope of the disclosure as defined by the appended claims. Furthermore, in the following detailed description of the present disclosure, numerous specific details are set forth in order to provide a thorough understanding of the present disclosure. However, it will be understood that the present disclosure may be practiced without these specific details. In other instances, well-known methods, procedures, components, have not been described in detail so as not to unnecessarily obscure aspects of the present disclosure.
FIG. 1 shows a web filtering mechanism 100 in one or more embodiments. The web filtering mechanism 100 filters web communication for a computing device 120 issued to a minor user 110 by an institution. The institution that issues the computing device 120 to the minor user 110 to can be a school and the minor user 110 can be a child attending the school. The web filtering mechanism 100 can perform any kind of web filtering, e.g., DNS filtering, search filtering, keyword filtering, etc.
The web filtering mechanism 100 includes an institutional policy dashboard 152 that enables the institution that issued the computing device 120 to the minor user 110 to select a set of institutional web access policies 162. The institutional web access policies 162 are web access policies sanctioned by the institution that issued the computing device 120 to the minor user 110.
The web filtering mechanism 100 includes a parental policy dashboard 150 that enables a parent 112 of the minor user 110 to select to a set of parental web access policies 160. The parental web access policies 160 are web access policies sanctioned by the parent 112.
The web filtering mechanism 100 includes a web filter 170 for filtering a web content accessed by the minor user 110 via the computing device 120 by enforcing the parental web access policies 160 and the institutional web access policies 162. In one or more embodiments, the web filter 170 enforces the parental web access policies 160 over the institutional web access policies 162 if the parental web access policies 160 and the institutional web access policies 162 conflict.
In one or more embodiments, the institutional policy dashboard 152 can be accessed by an institution admin 114 of the institution that issued the computing device 120 to the minor user 110. The institutional web access policies 162 can apply to groups that can encompass the minor user 110, e.g. a student grade level that encompasses the minor user 110. The parental web access policies 160 apply only to the minor user 110.
The institution admin 114 can access the institutional policy dashboard 152 via a network 140 using a client 132, e.g., a computer or mobile device running a web browser that accesses the web filtering mechanism 100 using web protocols. The parent 112 can access the parental policy dashboard 150 via the network 140 using a client 130, e.g., a computer or mobile device running a web browser.
The web filtering mechanism 100 holds the parental policy dashboard 150 in the same cloud site as the institutional policy dashboard 152. As a consequence, the parent 112 can use the client 130 to access the parental policy dashboard 150 and modify the policies sanctioned by the institutional that issued the computing device 120 to the minor user 110 without having to install any specialized software on the client 130 of the parent 112.
FIG. 2 illustrates the parental policy dashboard 150 in one or more embodiments. The parental policy dashboard 150 includes a set of content categories 210. In this example, the content categories 210 include social networking, gaming, and adult. There can be any number of content categories controllable via the parental policy dashboard 150 and the institutional policy dashboard 152.
The parental policy dashboard 150 lists the institutional web access policies 162 selected by the institution admin 114 via the institutional policy dashboard 152. The institutional web access policies 162 in this example are to deny the social networking, gaming, and adult categories.
The parental policy dashboard 150 enables the parent 112 of the minor user 110 of the computing device 120 to override one or more of the institutional web access policies 162. In this example, the parent 112 has selected via the parental policy dashboard 150 to allow social networking and gaming but to deny the adult category.
FIG. 3 shows the web filtering mechanism 100 establishing a trust relationship with the parent 112 before allowing the parent 112 to access the parental policy dashboard 150. The web filtering mechanism 100 establishes a trust relationship with the parent 112 in one or more embodiments by generating a login page accessible by the client 130 of the parent 112 such that the login page requires the parent 112 to login with a set of credentials that were issued to the minor user 110 by the institution that issued the computing device 120 to the minor user 110. For example, the institution admin 114 can register the login credential issued to the minor user 110 with the web filtering mechanism 100. Thereafter, those credentials can be used by the web filtering mechanism 100 to establish a trust relationship with the parent 112.
The web filtering mechanism 100 sends a respective confirmation email to the minor user 110 and the parent 112 and the institution that issued the computing device 120 to the minor user 110 when the credentials of the minor user 110 are used to login to the web filtering mechanism 100 and access the parental policy dashboard 150. The confirmation emails enable the minor user 110 and the parent 112 and the institution that issued the computing device 120 to detect fraudulent attempts to access the parental policy dashboard 150 by anyone posing as a parent.
In one or more embodiments, the web filtering mechanism 100 can establish a trust relationship with the parent 112 by providing a function in the institutional policy dashboard 152 that enables the institution admin 114 to send a link, e.g., a URL, for the parental control dashboard 150 in an email message to the parent 112. The link can enable the parent 112, and nobody else, to access the parental policy dashboard 150.
FIG. 4 shows an embodiment of the web filtering mechanism 100 that includes a location module 480. The location module 480 detects a current geographic location of the computing device 120 and provides the current geographic location to the web filter 170. The location module 480 enables the web filter 170 to adapt web access policies to the current geographic location of the computing device 120. In one or more embodiments, the web filter 170 enforces the institutional web access policies 162 when the geographic location of the computing device 120 is inside the institution that issued the computing device 120 to the minor user 110 and enforces the parental web access policies 160 when the geographic location of the computing device 120 is outside the institution that issued the computing device 120 to the minor user 110.
In one or more embodiments, the location module 480 determines a current geographic location for the computing device 120 by examining its IP address. For example, the location module 480 can include a list of IP addresses associated with the institution that issued the computing device 120 to the minor user 110. The location module 480 can detect an IP address currently used by the computing device 120 to communicate on the network 140 and if it is an IP address not associated with the institution that issued the computing device 120 then it can be concluded that the computing device 120 is located outside of the institution that issued the computing device 120.
In one or more embodiments, the location module 480 determines a current geographic location for the computing device 120 by employing a web-based geo-location service that analyzes messages from the computing device 120 to determine its geographic location. The location module 480 can compare the current geographic location of the computing device 120 to the geographic location of the institution that issued the computing device 120 to the minor user 110 to determine whether or not the computing device 120 is currently located inside or outside of the institution.
In one or more embodiments, the location module 480 determines a current geographic location for the computing device 120 by employing a GPS mechanism in the computing device 120. The location module 480 can compare the current geographic location reported by the GPS mechanism inside the computing device 120 to the geographic location of the institution that issued the computing device 120 to the minor user 110 to determine whether or not the computing device 120 is currently located inside or outside of the institution.
The location detection by the location module 480 can be selected to be natively supported by the computing device 120 and one or more web browsers that can be run on the computing device 120. This can minimize barriers to location-based parental controls that might otherwise be imposed on the parent 112 or the minor user 110. For example, no software installation is imposed on the parent 112 to track the location-usage of the computing device 120 by their minor user 110 when a geo-location service or device GPS or IP tracking is used by the location module 480.
FIG. 5 shows how the web filtering mechanism 100 determines which set of policies, the parental web access policies 160 or the institutional web access policies 162, are to be applied to the computing device 120 in one or more embodiments. At step 510, the web filtering mechanism 100 determines a current geographic location of the computing device 120. Step 510 can include determining a precise geographic location, e.g., using a web-based geo-location service or a GPS mechanism in the computing device 120, or determining a current IP address being used by the computing device 120.
At step 520, the web filtering mechanism 100 determines whether or not the current geographic location of the computing device 120 is outside of the institution that issued the computing device 120 to the minor user 110. The determination at step 520 can be based on any geographic location measure, e.g., latitude/longitude, street address, etc., or on a comparison between the current IP address of the computing device 120 and the IP addresses associated with the institution that issued the computing device 120 to the minor user 110.
If the current geographic location of the computing device 120 is not outside of the institution that issued the computing device 120 to the minor user 110 at step 520, then at step 530 the web filtering mechanism 100 filters web communication for the computing device 120 by applying the institutional web access policies 162. Otherwise, at step 540 the web filtering mechanism 100 filters web communication for the computing device 120 by applying the parental web access policies 160.
FIG. 6 shows one or more embodiments of the web filtering mechanism 100 integrated with a reporting mechanism 660 including an activity log 610. The activity log 610 records a set of web accesses undertaken with the computing device 120. The activity log 610 can also record the current geographic locations of the computing device 120 when the recorded web accesses were undertaken. The activity log 610 can be used to provide reports to the parent 112 about what web sites the minor user 110 has accessed from what location.
The web filtering mechanism 100 can employ a geo-location service 620 to determine the current geographic location of the computing device 120. The geo-location service 620 can obtain consent for location tracking from the minor user 110 before tracking the location of the computing device 120. The location module 480 can then at any time obtain the current geographic location of the computing device 120 from the geo-location service 620, e.g., using IP/web communication via the network 140.
FIG. 7 illustrates the activity log 610 in one or more embodiments. The activity log 610 includes a set of records 0-n. Each record 0-n can describe a web access undertaken by the minor user 110 via the computing device 120. Each record 0-n in one or more embodiments can include a content category C0-Cn, a street address A0-An, a starting time TO-Tn, and a duration D0-Dn. The content categories C0-Cn describe the content being accessed, e.g., social network, gaming, adult, etc. The street addresses AO-An are the geographic locations of the computing device 120 during the corresponding web accesses. The starting times TO-Tn and the durations DO-Dn are the starting time and durations for the corresponding web accesses.
FIG. 8 shows an activity analyzer 840 in the reporting mechanism 660 in one or more embodiments. The activity analyzer 840 generates an activity report 850 from the information in the activity log 610. The activity analyzer 840 can generate any type of report, table, chart, graph, etc. that depicts the information in the activity log 610. For example, the activity analyzer 840 can generate a pie chart that depicts the percentage of time that the minor user 110 spends on each of the content categories recorded in the activity log 610.
The activity analyzer 840 can generate the activity report 850 in one or more embodiments by correlating the information in the activity log 610 with information contained in a performance data store 820. The performance data store 820 can hold performance data pertaining to the minor user 110, e.g. test grades. The activity analyzer 840 can generate activity reports that link test grades to web access activity logged in the activity log 610. For example, large amounts of time logged on social networking before a test period can be correlated to resulting test performance.
In one or more embodiments, the reporting mechanism 660 includes a push notification server 880 that can send the parent 112 the activity report 850 in an email message. The push notification server 880 can regularly send activity reports, e.g., weekly reports, so that the parent 112 can track how much time the minor user 110 is spending on the categories that the parent 112 currently allows. The regular reports can enable the parent 112 to adjust their choices on content categories accordingly. In one or more embodiments, activity reports can be sent to a mobile device of the parent 112, e.g. the client 130 or another device that runs a mobile app for receiving activity reports from the push notification server 880.
FIG. 9 shows an urgency module 990 in the reporting mechanism 660 in one or more embodiments. The urgency module 990 detects a potential for harm to the minor user 110 by examining the web content accessed using the computing device 120 and sends an urgent message to the parent 112 if the potential for harm is detected. The urgency module 990 obtains an information stream from the web filter 170 that includes text associated with web content accessed by the minor user 110 via the computing device 120. The text from the web filter 170 can include search terms typed into search engines, content of instant messages, text extracted from web sites visited by the minor user, etc. The urgency module 990 examines the information stream for key words, phrases, etc., that can indicate interactions by the minor user 110 with potential predators, bullies, etc., as well as conditions that may cause the minor user 110 to engage in self-harm. When the urgency module 990 detects a potential for harm to the minor user 110 it sends an urgent message via the push notification server 880 to the parent 112 informing the parent 112 of the potential danger. The urgent message can be a text or other instant message to a mobile device of the parent 112.

At step 1030, web content accessed by the minor user via the computing device issued by the institution is filtered by enforcing the parental and the institutional web access policies. The parental web access policies can be enforced over the institutional web access policies if the parental web access policies and the institutional web access policies conflict at step 1030.
FIG. 11 illustrates a method for web filtering integrated with parental reporting in one or more embodiments. At step 1110, a web content accessed by a minor user via a computing device issued to the minor user by an institution is filtered. At step 1120, a set of web accesses undertaken by the minor user via the computing device is reported to the parent of the minor user.
