This document relates to information processing.
The World Wide Web is a system of interlinked documents, or web pages, accessible through the Internet. Generally, web pages can be accessed by a client device running a browser application. A Web cookie containing text information can be sent by a web page server to a browser accessing the web page and the cookie can be sent back each time the browser accesses the web page. Some web page owners and other publishers include advertising content on their pages.
In a first aspect, a computer-implemented method for controlling content distribution includes forwarding information associated with a user to a device operated by the user, the information being configured for use in selecting content from any of multiple content providers for a content distribution to the user. The method includes receiving, in response to the information, an edit of the information forwarded from the device. The edit identifies a first content provider and including a first modification of the content distribution regarding the first content provider. The method includes storing the edit in association with the information such that the first modification is taken into account in the content distribution. The method can be implemented using a computer program product tangibly embodied in a computer-readable storage medium.
Implementations can include any, all or none of the following features. The content distribution can take place under an arrangement where the content providers provide advertising content for publication in connection with content from any of a plurality of publishers, the plurality of publishers can receive compensation from the content providers in return for publication, and the edit can permit the user to exercise control over which of the advertising content is included in the content distribution. The information can further identify at least one interest that has been associated with the user for selecting the content for the content distribution, the edit can further include a second modification of the content distribution regarding the interest, and the edit can be stored such that the second modification also is taken into account in the content distribution. The first modification can include altering the plurality of content providers to add or delete the first content provider; and the second modification can include altering the content distribution to add or delete the interest as being associated with the user. The edit can further include a user-defined modification of the content distribution regarding an interest, and the edit can be stored such that the user-defined modification also is taken into account in the content distribution.
The first content provider may have retargeted the user in response to the user accessing content associated with the first content provider, and the information can identify the first content provider to the user as having retargeted the user. The edit can specify that the first content provider is to be blocked from retargeting the user but that the first content provider can provide content to the user in the content distribution based on the information taking into account the first modification. The edit can further include a user preference specification regarding the content distribution, and the edit can be stored such that the user preference specification also is taken into account in the content distribution. The user preference specification can define that the user prefers at least one of a text format and a graphic format for the content distribution.
The user preference specification can define that the user prefers at least one of multiple attributes for the content distribution. The method can further include receiving a user identifier associated with the user and accessible on the device for any of the multiple content providers to obtain the information for selecting the content for the content distribution. The user identifier can be forwarded from the device to obtain the information, and the information can be forwarded to the device in response to receiving the user identifier. The method can further include providing to the device executable instructions for execution on the device, and the information can be forwarded to the device in response to receiving a request for the information from the device.

The details of one or more implementations are set forth in the accompanying drawings and the description below. Other features and advantages will be apparent from the description and drawings, and from the claims.
Like reference symbols in the various drawings indicate like elements.
The system 100 in this example includes a computer device 102, one or more content distribution systems 104, one or more content provider systems 106, and one or more content publisher systems 108, here connected by a network 110. Any kind of computer devices can be used including, but not limited to, personal computers, handheld devices such as cellular phones, and/or server devices. Components in the system 100 can be connected by any kind of network, such as a private network or the Internet. For example, the computer device 102 can be operated by an individual who accesses resources in a network, for example web pages on the Internet.
The content provider system 106 can, for example, be operated by one or more content providers. The content providers can provide content such as advertisements intended for presentation to the user(s) on the computer device 102, for example. Content can include any kind of media, such as elements of text, video, animation, sound, and/or interactive components, to name a few possibilities. Elements of content can be tailored for a specific user, based on defined user interests and preferences, for example. For example, a shoe company can designate a shoe advertisement intended for presentation to the general public and a separate shoe advertisement intended for targeted presentation to any or all users with an interest in the outdoors.
User interest data can be compiled by a variety of methods, including self-reporting by users, and user registration and/or patronage of resources such as websites associated with particular advertisers or interests, to name a few possibilities. Procedures can be put in place to protect user privacy, such as through the provision of a user privacy policy, and/or to allow a user to opt out of information-sharing systems. The content publisher system 108 can, for example, be operated by one or more content publishers. The content publisher(s) can provide content such as websites or any other kind of media to be accessed by a user of the computer device 102, for example. The content publisher can present information and content such as text, video, sound, and games (to name a few possibilities) to visitors of the sites. Additionally, the content publishers can present content (such as advertising content, for example) from content providers. For example, the content distribution can take place under an arrangement where content providers provide content such as advertising for publication in connection with content from one or more publishers, and the publishers receive compensation in return for publication.
The content distribution system 104 can, for example, serve a coordinating role in determining which content provided by one or more content providers to make available in connection with one or more content publishers. The content distribution system 104 in this example includes a content database 112 and an information database 114. Here, for example, information regarding advertising content from a content provider can be sent from the content provider system 106 to the content distribution system 104 via the network 110 and stored in the content database 112. In some implementations, information regarding a device user can be collected by methods including the previously described exemplary methods and stored in the information database 114, for example. In the present example, information regarding a device user can be retrieved from the information database 114 and used by the content distribution system 104 to determine which advertising content can be made available in connection with a web page provided by a content publisher associated with the content publisher system 108.
The computer device 102 in this example includes at least one cookie 116, a cookie viewer application 118, and a cookie viewer interface 120. Each user of the device 102 can be associated with one or more cookies, for example. The computer device 102 can, for example, be controlled by a user to access a web page on the Internet. In the present example, the cookie 116 can be placed on the computer device 102 by a server device associated with the content publisher system 108 via the network 110. The placement of the cookie 116 may be, for example, in temporal connection with the user visiting a page or other content provided by the server. Here, for example, the computer device 102 can store the cookie 116 including an identifier associated with the user. In some implementations, the cookie 116 can include essentially only a user identifier. For example, a user identifier associated with a user and accessible on the device 102 can be received by the content distribution system 104 for one or more content providers to obtain information for selecting the content for content distribution. Here, for example, a user identifier can be forwarded from the device 102 to obtain the information, and the information can be forwarded to the device 102 in response to receiving the user identifier.
In the present example, the cookie viewer application 118 can be a computer program product tangibly embodied in a computer-readable storage medium. The cookie viewer application can include instructions that, when executed, generate on a display device associated with the computer device 102 a graphical user interface for controlling content distribution, for example the cookie viewer interface 120.
In some implementations, the cookie viewer application 118 and/or the cookie viewer interface 120 can provide user access or control of information used in content distribution to the user. For example, the cookie viewer application 118 can be configured for generating a request for information associated with a user and/or can define an edit to the information. In some implementations, a user can download the cookie viewer application 118 and can install the application 118 on the computer device 102. In the present example, the application 118 can be delivered by a website associated with the content distribution system 104.
The application 118 can, for example, run on the device 102 and can pass the cookie 116 or information associated with the cookie 116 via the network 110 to the content distribution system 104. The content distribution system 104 can use the cookie 116 or an associated identifier to locate information in the information database 114 relating to a user of the device 102, for example. The information can include user interests, content display preferences, content provider preferences, and/or information relating to one or more content providers targeting a user, to name a few examples. The information or a subset of the information associated with a device user can, for example, be forwarded to the device 102 via the network 110. The information can be configured for use in selecting which content from providers to distribute to a user, for example. In the present example, information associated with a device user can be received by the computer device 102 and can be presented on a display device associated with the device 102.
In the present example, the cookie viewer application 118 can present the cookie viewer interface 120. For example, the cookie viewer interface 120 can include an information edit area generated on a display device associated with the computer device 102 for a user to specify an edit of information configured for use in selecting content from any of multiple content providers for a content distribution to the user. The edit in the present example can identify a content provider (such as a shoe company, for instance) and can include a modification of the content distribution regarding the content provider. For example, a user can choose to enable or disable targeted advertising content from the shoe company. In the present example, the cookie viewer interface 120 can cause the edit of the information made by the user to be registered and to be stored in association with the information such that the modification is taken into account in the content distribution. Here, for example, the edit can be forwarded to the content distribution system 104 via the network 110 and stored by the system 104. Information associated with a particular user and edits made to the information by the user can be used by the content distribution system 104 to provide user control over which of the advertising content is included in the content distribution, for example whether general or targeted shoe company advertising content is to be presented to a particular user. In some implementations, other edits regarding content providers can be made. For example, the user can be able to explicitly select one or more content providers so that content from the selected provider(s) is received.
In some implementations, the information can identify one or more interests that have been associated with a user for selecting the content for content distribution. For example, it can be determined by methods such as the previously presented exemplary methods that a user has interests in the outdoors and in sports. The information can be presented by the cookie viewer interface 120, for example, and the user can be allowed to edit the information. In some implementations, a user can add or delete associated interests. Here, for example, a user can choose to deselect or disable an interest in sports and to select or enable an interest in gadgets, and the edit can be stored such that the modification is taken into account in the content distribution. For example, the content distribution system 104 can determine that content associated with selected interests (such as outdoors and gadgets) is to be presented to a user and that content associated with deselected interests (such as sports) is not to be presented. In some implementations, other edits regarding interests can be made. For example, the user can be able to explicitly select and/or enter one or more interests so that content regarding the selected interest(s) is delivered to the user.
In some implementations, a user can add or delete content providers. For example, a user can specify a preference to receive content from one electronics store, but not to receive content from another electronics store. In some implementations, a content provider can be referred to as anonymous. For example, an advertiser that delivers targeted advertising can express a preference to not identify itself. In the present example, advertisers choosing anonymity can be referred to as anonymous in the cookie viewer interface 120. Here, for example, a user can specify a preference to not receive targeted advertisements from anonymous content providers.
In some implementations, the edit to the information can include a user-defined modification. For example, a user can have an interest in an interest category such as home recording. In the present example, a free-form entry control can be provided via the cookie viewer interface 120 to allow for such additions. An edit including a user-defined modification of content distribution regarding an interest can be stored such that the user-defined modification is taken into account in the content distribution, for example.
In some implementations, a content provider can retarget a user in response to the user accessing content associated with the content provider. For example, a user can register with a website operated by a shoe company and be subsequently provided with retargeted advertising content, such as personalized advertisements, when the user visits the same and/or another page, for example. Here, for example, via the cookie viewer application 118 and the cookie viewer interface 120, one or more content providers (e.g. the shoe company) can be identified as having retargeted the user. In the present example, the user can specify that the content provider (e.g. the shoe company) is to be blocked from retargeting the user but that the content provider can provide content to the user based on prior modifications.
In some implementations, a user can specify a preference regarding the content distribution. A user can specify a preference for one or more attributes for content distribution, such as text, graphics, video, animation, sound, or interactivity, to name a few examples. Here, for example, via the cookie viewer application 118 and/or the cookie viewer interface 120, a user can specify a preference for content including video and sound. In the present example, the edit can be stored such that the user preference specification is taken into account in the content distribution.
In some implementations, a predetermined number of content portions can be identified as having been most recently presented to a user in the content distribution. For example, the content distribution system 104 or the cookie viewer application 118 can track the ten most recent advertisements that were presented to a user. In the present example, a graphical user interface associated with the cookie viewer application 118 can cause at least part of each of the ten advertising content portions to be again presented on the device, such as in the interface 120. Here, the application 118 can receive an input generated by the user identifying at least one of the advertising content portions and can include an edit of the information regarding the portion(s). For example, a user can specify a preference that one or more advertisements are, or are not, to be subsequently displayed. In the present example, the edit can be stored such that one or more of the identified content portions is to be blocked from being presented on the device.
The process 200 can, for example, be initiated by a user accessing content such as a web page on the Internet by using a computer device such as a desktop or portable computer, a server, or a cell phone, to name a few examples. In the present example, the process 200 can include a step 202 for visiting a web page. Here, for example, the web page can be associated with a content publisher in the system 100. In other implementations, the web page can be associated with another entity in the system 100, such as a content provider or content distributor.
The process 200 can include a step 204 for downloading a cookie viewer. In some implementations, the cookie viewer can be downloaded from a web page, such as a web page visited in step 202, or a web page associated with the content distribution system 104, for example. Here, for example, step 204 can include receiving at the device instructions for execution. In the present example, the executable instructions can be configured for generating a cookie viewer application on the device. The cookie viewer can be a stand-alone application, or an application running within a web browser, to name a couple of examples.
The process 200 can include a step 206 for running a cookie viewer. For example, the cookie viewer can be a cookie viewer downloaded in step 204. In some implementations, step 206 can include executing instructions that can generate on a display device a graphical user interface. The interface can, for example, allow a user to view and/or edit information associated with an Internet cookie stored on a computer device.
The process 200 can include a step 208 for viewing recent content(s). For example, the content(s) can be presented to the user by an application such as a cookie viewer run in step 206. In some implementations, a predetermined number of content portions can be identified as having been most recently presented to the user. For example, ten advertisements or portions of the ten advertisements most recently presented to a user (by a web browser, for example) can again be presented on the device. In the present example, the contents can be retrieved by a computer device forwarding a cookie or information associated with a cookie to a server that can track content (e.g. advertising) previously sent to a particular device. Here, content or portions thereof can be retrieved, for example from a database, and resent to a requesting device. In some implementations, content or portions of content can be cached on the computer device itself.
The process 200 can include a step 210 where the user makes one or more edits. In some implementations, the edit can permit the user to exercise control over advertising content to be included in the content distribution. For example, the edit(s) can be made relating to recently presented content viewed in step 208. In the present example, a user can identify one or more of the ten content portions (e.g. advertisements) most recently presented to the user and specify that the identified content portion(s) are to be blocked from being presented on the device. In some implementations, a user can identify one or more content portions and can express a positive or negative preference for the identified content portions. In some implementations, a user can identify one or more content providers and can express a positive or negative preference for the identified content providers.
The process 200 can include a step 212 for forwarding one or more edits. For example, the forwarded edit(s) can be the edit(s) made in step 210. In the present example, the edit(s) can be forwarded to a server storing preference information, for example, a server associated with the system 100. Here, for example, edit(s) signifying a blocking preference can be used by the system 100 to prevent presentation of one or more content portions. For example, the presentation of a content portion (e.g. an advertisement) to a user can be prevented upon receiving edit(s) from the user specifying a preference for blocking the content portion. Blocking can be performed by one or more servers associated with the system 100 or by a device operated by a user, for example. In some implementations, edit(s) signifying positive or negative content preference data associated with a user or a set of users of the system 100 can be used to determine a frequency and/or schedule for the presentation of one or more content portions. For example, a user can specify a preference for a specific content portion. The specified preference can be used by the system 100, for example to increase the frequency of display of the content portion and/or related content portions to the user and/or related users. For example, a content portion associated with a positive user preference can be presented more frequently to another user or another set of users determined to be similar, such as users having similar interests.
In some implementations, a user can opt out of some or all targeted advertising through use of an optional persistent opt-out cookie that is managed through a browser plug-in. The opt-out cookie may be, for example, a client-side cookie with a non-tracking id such as id=OPT_OUT. For example, an opt-out browser plug-in can monitor the existence of the opt-out cookie, and can reset the opt-out cookie in case it is removed. The opt-out plug-in can take the form of, for example, a browser extension or browser ad-on. Once installed, the plug-in automatically opts-out of targeted advertisements, or, in some implementations, adds an opt-out menu item to the browser tools menu or other browser user interface providing the capability to opt-out of targeted advertising cookies.
When enabled, the extension or add-on can respond to events such as, for example, the completed rendering of a web-page, the manually deletion of a cookie through the browser's functions, or cookie modification through third party software. Either immediately upon these events or after a timeout period, such as, for example, a configurable timeout period set to 10 minutes by default, the extension can programmatically restore the opt-out cookie if it no longer exists. If the browser settings are inconsistent with the opt-out plug-in, such as, for example, when the browser is configured to “block 3rd party cookies”, the extension can be grayed out and an alert to the user, through a bubble, tool-tip, or the like may be presented. Such an opt-out browser plug-in may be configured as part of the preferences tool to, for example, respect selections made by the user and/or opt-out of certain types of advertisements.
The process 300 can, for example, be initiated by a server accessed by a device over a network such as a desktop or portable computer, a cell phone, or another server, to name a few examples. In the present example, the process 300 can include a step 302 for registering information. Here, for example, registering of information can be performed by a server in the system 100, such as a server associated with a content distributor, a content provider, or a content publisher. The information can be associated with a device such as a computer device in the system 100 and/or a user controlling a device, for example. In the present example, a device can provide information to a server upon accessing a web page associated with the server. Here, for example, information can include, but is not limited to information such as user name(s), password(s), preferences, and/or device-related information.
The process 300 can include a step 304 for placing a cookie. For example, a cookie can be placed on a computer device by a server upon registering device information, such as in step 302. In some implementations, a server registering information associated with a user and/or a device can place a cookie including a user and/or a device identifier. For example, identifier(s) can be unique ID(s) generated by a server associated with the system 100. In the present example, one or more identifiers can be stored in a database associated with the server with information related to one or more users and/or one or more devices. Information related to user(s) and/or device(s) can be stored and retrieved by using associated identifier(s).
The process 300 can include a step 306 for forwarding a cookie viewer application. For example, a cookie viewer can be forwarded to a computer device having a placed cookie, such as a cookie placed in step 304. In the present example, a cookie viewer can be forwarded to a device by a server associated with the system 100. In some implementations, a cookie viewer can include executable instructions for execution on a device configured for a user to view information and/or to define an edit to information associated with a user and/or device.
The process 300 can include a step 308 for receiving one or more edits. In some implementations, edit(s) can be performed by a user operating a computer device such as a device running a cookie viewer downloaded in step 306, for example. Here, for example, information can be forwarded to the device in response to receiving a request for information from the device. Information can be forwarded by a server associated with the system 100, for presentation on the device, for example. In the present example, information can include, but is not limited to information such as content preference(s) relating to provider, interest, presentation, and/or format. Here, for example, a server can receive one or more edits to the information made by a user operating an interface associated with a cookie viewer.
The process 300 can include a step 310 for storing one or more edits. For example, the edit(s) can be edit(s) received in step 308. In some implementations, edit(s) can be associated with one or more identifiers, such as user and/or device identifiers, for example. In the present example, identifier(s) can be included in a cookie placed on a computer device in step 304. The cookie or identifier(s) included in the cookie can be used by a server for storing related edit(s) in a database, for example.
The process 300 can include a step 312 for providing content. For example, content can be provided by a server associated with the system 100 to a computer device associated with the system 100. In some implementations, a method for determining the content that can be provided to a device can take into account information associated with a user and/or a device as well as edit(s) to the information, such as edit(s) stored in step 310, for example. In the present example, provided content can include text, video, animation, sound, and/or interactive elements, to name a few possibilities. Here, for example, content can be associated with one or more providers, interests, presentation styles and formatting types. In some implementations, a determination of content to be provided to a user and/or a device can be based at least in part on stored information and/or edit(s) associated with the user and/or the device. For example, a server such as a server in the system 100 can compare the content with the information and/or edit(s) and can determine whether characteristics of the content match preferences expressed in the information and/or edit(s). In some implementations, a server can take into account one or more preferences expressed in the information and/or edit(s) associated with a set of users and/or devices related to a user and/or device when determining which content to provide. For example, a user can be identified as having a positive or negative interest in sports by considering information and/or edit(s) associated with the user. Here, for example, a server can provide content preferred by one or more other users with a similar interest in sports.
In some implementations, provided content can include advertising content for presentation in a web browser, for example. In some implementations, provided content can include entertainment and/or information content, such as music, video, animation, news, and/or gaming content, to name a few examples. The content can be presented by a web browser or a non-browser application running on a computer device, for example. In some implementations, content can be presented on a device in communication with the computer device, such as peripheral video and/or sound devices, or another computer device, to name a few examples.

Suitable processors for the execution of a program of instructions include, by way of example, both general and special purpose microprocessors, and the sole processor or one of multiple processors of any kind of computer. Generally, a processor will receive instructions and data from a read-only memory or a random access memory or both. The essential elements of a computer are a processor for executing instructions and one or more memories for storing instructions and data. Generally, a computer will also include, or be operatively coupled to communicate with, one or more mass storage devices for storing data files; such devices include magnetic disks, such as internal hard disks and removable disks; magneto-optical disks; and optical disks. Storage devices suitable for tangibly embodying computer program instructions and data include all forms of non-volatile memory, including by way of example semiconductor memory devices, such as EPROM, EEPROM, and flash memory devices; magnetic disks such as internal hard disks and removable disks; magneto-optical disks; and CD-ROM and DVD-ROM disks. The processor and the memory can be supplemented by, or incorporated in, ASICs (application-specific integrated circuits).
To provide for interaction with a user, the features can be implemented on a computer having a display device such as a CRT (cathode ray tube) or LCD (liquid crystal display) monitor for displaying information to the user and a keyboard and a pointing device such as a mouse or a trackball by which the user can provide input to the computer.
The features can be implemented in a computer system that includes a back-end component, such as a data server, or that includes a middleware component, such as an application server or an Internet server, or that includes a front-end component, such as a client computer having a graphical user interface or an Internet browser, or any combination of them. The components of the system can be connected by any form or medium of digital data communication such as a communication network. Examples of communication networks include, e.g., a LAN, a WAN, and the computers and networks forming the Internet.
The computer system can include clients and servers. A client and server are generally remote from each other and typically interact through a network, such as the described one. The relationship of client and server arises by virtue of computer programs running on the respective computers and having a client-server relationship to each other.
A number of implementations have been described. Nevertheless, it will be understood that various modifications may be made without departing from the spirit and scope of this disclosure. Accordingly, other implementations are within the scope of the following claims.
