Managing privacy settings for a social network

## Abstract

Methods for managing privacy settings for a social network using an electronic computing device are presented including: causing the electronic computing device to receive a triggering event on the social network; and causing the electronic computing device to determine a number of privacy indices in response to the triggering event, where the number of privacy indices correspond with at least one target user, where the number of privacy indices are normalized from a summation of a number of privacy scores, where the number of privacy scores are each derived from a sum of attribute scores, and where the sum of attribute scores are each derived from a weighted sensitivity value of an attribute and a user relationship distance value of a user and the target user.

## Background
BACKGROUND
As social networking becomes more prevalent across the Internet, more user information is potentially exposed across a wide variety of sites. While social networking applications have empowered users to share friends, music, and numerous aspects of their personalities, they have also raised numerous privacy concerns. Many users may wish to freely share information between close associates, but would also prefer to keep sensitive personal information safe from other third parties whose interest in such information may not be in a user's best interest.
Most social networks utilize varying degrees of privacy protection. User logon and password authentication are the most common. However, this first level of protection only ensures that the person having the password has the right to be on the network. One approach utilized to increase security in some social networks is to establish preferences that correspond with privacy settings. However, this coarse granularity in privacy settings may not adequately protect sensitive information. For example, preferences may be established for a social network in which a user has close friends as well as casual acquaintances. In those cases, utilizing a preference model may be too broad to protect an individual user's privacy interests.
Another issue confronting privacy is that some privacy settings schemes are simply too complex for users to easily navigate. In those examples, schemes requiring multiple levels of security may result in users ignoring settings altogether or inadvertently exposing sensitive information. As such, managing privacy settings for a social network are provided herein.

Application server 110 may be configured with a number of components for enabling embodiments described herein. As illustrated, application server 110 may include controllers 112 for enabling interactions between privacy manager 120, user interface (UI) 114, and models component 116. UI 114 and models component 116 may be configured to cooperatively and graphically display privacy settings as determined by privacy manager 120 on an electronic computing device. A user interface embodiment, such as may be displayed on a computing device, may be configured to display current and recommended privacy settings. As such, a user may, in embodiments, utilize UI 114 to select either current privacy settings, recommended privacy settings. In addition, UI 114 may be configured to accept custom user privacy settings in some embodiments. Displaying privacy settings on an electronic computing device will be discussed in further detail below for FIG. 4. Models component 116 may be configured to manage visualization of any discretionary privacy settings available to a user for modification utilizing embodiments described herein.
Application server 110 further includes privacy manager 120. Privacy manager 120 may include several modules for enabling embodiments described herein. Privacy score calculator module 122 may be configured to determine a number of privacy indices in response to some triggering event associated with social network 102. Furthermore, privacy score calculator module 122 may be configured to implement any range of privacy score calculations. Privacy scores indicate a level of privacy or security. As utilized herein, a privacy score is an aggregation of all attribute scores of a user or target. In embodiments, a high privacy score is indicative of a more secure privacy setting. Likewise, in embodiments, a low privacy score is indicative of a weaker privacy setting. Privacy scores will be discussed in further detail below for FIG. 2. Privacy score calculator module 122 may be further configured to calculate a privacy index. As utilized herein, privacy indices are normalized from a summation of privacy scores of a user or target. In embodiments, a high privacy index is indicative of a more secure privacy setting. Likewise, in embodiments, a low privacy index is indicative of a weaker privacy setting. Privacy indices will be discussed in further detail below for FIG. 2.
Privacy manager 120 may further include privacy enforcer module 124. In embodiments, privacy manager 120 may be configured to manage conflicts associated with accepting privacy recommendations. As may be appreciated, in utilizing embodiments described herein, conflicts may arise in managing privacy settings. For example, in a preferred embodiment, a conflict will always be resolved to a more secure privacy setting. However, in other embodiments, conflicts may be resolved in any arbitrary fashion without limitation. Privacy manager 120 may further include privacy model module 126. In embodiments privacy model module 126 may be configured to manage a user relationship. A user relationship may be utilized to determine a user relationship distance value, which may be characterized as a quantification of trust between a user and target. In some embodiments, user relationships may include without limitation: a close friend relationship, a friend relationship, a friend of a friend relationship, an acquaintance relationship, a group relationship, and a network relationship. Each of these relationships defines a level of trust. For example, a close friend relationship may be more “trustworthy” than a network relationship. Thus, a user having a close friend relationship with a first target might logically be more inclined to share more sensitive information with the first target than with a second target where the second target has a network relationship with the user.
Privacy manager 120 may further include privacy elections module 128. In embodiments, privacy elections module 128 may be configured to designate a user relationship between a user and a target. As noted above, a user relationship may be utilized to determine a user relationship distance value, which may be characterized as a quantification of trust between a user and target. Privacy elections module 128 may be configured to establish what level of relationship is appropriate. In some embodiments, privacy elections module 128 may be configured to receive input from a user. In other embodiments, privacy elections module 128 may be configured to receive input from social network 102. Privacy manager 120 may be further configured to access repository 118. Repository 118 may be configured to store non-transient data associated with privacy manager 120. In some embodiments, repository 118 may include a database that is accessible via a database management system (DBMS). In other embodiments, repository 118 may include a hardware storage medium. In still other embodiments, repository 118 may be located locally or remotely and may be accessible through any method known in the art without limitation.
FIG. 2 is an illustrative flowchart 200 of methods for managing privacy settings for a social network in accordance with embodiments of the present invention. At a first step 202, the method receives a triggering event. A triggering event as utilized herein is merely an event that initiates methods described herein. In embodiments, triggering events may include without limitation: a user creates a group, a user joins a group, a user leaves a group, a group adds a group member, a group changes status, a user creates a network, a user joins a network, a user leaves a network, a network adds a network member, a network changes status, a user adds a friend, a user removes a friend, a friend adds a user, a friend removes a user, a user initiates an account, a user adds an application, a user removes an application, and a periodic timer elapses. In embodiments, periodic timers may be set for any range or dependency without limitation. In addition, in embodiments, triggering events may be processed individually upon event occurrence, processed by batch, or processed randomly without limitation. Triggering events may be processed, in some embodiments, in a manner as to limit network traffic caused by processing methods described herein.
At a next step 204, the method determines privacy indices related to a triggering event. As noted above, privacy indices are normalized from a summation of privacy scores of a user or target. In embodiments, a high privacy index is indicative of a more secure privacy setting. Likewise, in embodiments, a low privacy index is indicative of a weaker privacy setting. Determination of privacy indices will be discussed in further detail below for FIG. 3. At a next step 206, the method calculates recommended privacy settings. Recommended privacy settings are based on privacy indices that are determined in a previous step. In embodiments, a more secure privacy setting is calculated from a high privacy index. Likewise, in embodiments, a weaker privacy setting is calculated from a low privacy index. In a preferred embodiment, a recommended privacy setting is always a more secure (or higher) privacy setting. However, recommended privacy settings may be calculated from other privacy indices having weaker privacy settings in other embodiments without limitation.
At next steps 208 and 210, the method displays current privacy settings and recommended privacy settings. As noted above for FIG. 1, a UI 114 may be configured to display current privacy settings on an electronic computing device. As such, in embodiments, UI 114 may be configured to display current privacy settings, recommended privacy settings, or both current privacy settings and recommended settings. Displaying privacy settings on an electronic computing device will be discussed in further detail below for FIG. 4. Returning to FIG. 2, at a next step 212, the method determines whether recommended privacy settings are greater (or higher) than current privacy settings. If the method determines as a step 212 that recommended privacy settings are not greater than current privacy settings, the method continues to a step 218 to keep optionally current privacy settings. In some embodiments, when recommended privacy settings are not greater than current privacy settings, then no recommendation is made.
If the method determines as a step 212 that recommended privacy settings are greater than current privacy settings, the method continues to a step 214 to determine whether to optionally change privacy settings. If the method determines at a step 214 not to change privacy settings, the method continues to a step 218 to keep current privacy settings. If the method determines at a step 214 to change privacy settings, the method continues to a step 216 to change current privacy settings to recommended privacy settings. In some embodiments, changing to higher recommended privacy settings may be enforced automatically. In other embodiments, a user may choose whether or not to select recommended privacy settings. In still other embodiments, a user may change current privacy settings to include a subset of recommended privacy settings resulting in higher or lower privacy settings independent of recommended privacy settings. The method then ends.
FIG. 3 is an illustrative flowchart 300 of methods for calculating a privacy index in accordance with embodiments of the present invention. In particular, FIG. 3 is an illustrative flowchart 300 of a step 204 (see FIG. 2). At a first step 302, a target is selected. A target, as utilized herein, is another user under inspection. In embodiments, a target may be a member of a group or network without limitation. At a next step 304, a user attribute is selected. A user attribute is some characteristic defined by a model in a social network. For example, if a model on a social network is contact information, then one attribute might be a last name. In embodiments, models may have any number of attributes and social networks may have any number and type of models. Furthermore, attributes may be shared based on a user's preferences as embodied in a privacy setting. Thus, a user not wishing to share any contact information may be denoted as having a high privacy index, whereas a user sharing all contact information may be denoted as having a low privacy index. In embodiments, attributes may include without limitation: a personal data attribute, a contact data attribute, an education data attribute, a business data attribute, a hobby data attribute, an interest data attribute, and a user relationship data attribute.
At a next step 306, the method gets a weighted sensitivity value of a user attribute. A weighted sensitivity value of a user attribute is a numeric representation of the sensitivity of the attribute to a user. For example, an attribute such as social security number may have a high weighted sensitivity value representing highly sensitive information where another attribute such as first name may have a low weighted sensitivity value representing non-sensitive information. Weighted sensitivity values may be gathered from any source without limitation without departing from the present invention. At a next step 308, the method determines a user relationship distance value, which is a numeric representation of the distance between a user and a target. As may be appreciated, a close relationship generally equates with more trust while a further relationship generally equates with less trust. In embodiments, relationship may include without limitation: a close friend relationship, a friend relationship, a friend of a friend relationship, an acquaintance relationship, a group relationship, and a network relationship.
At a next step 310, the method calculates an attribute score. An attribute score is calculated from a weighted sensitivity value and a relationship distance value. In a preferred embodiment, the weighted sensitivity value is multiplied by the distance value to generate an attribute score. In other embodiments, an arithmetic value is generated. At a next step 312, the method determines whether an attribute under inspection is a last attribute. If the method determines at a step 312 that the attribute under inspection is not a last attribute, the method continues to a step 304 to select another attribute for inspection. In this manner the method iterates through all attributes. If the method determines at a step 312 that the attribute under inspection is a last attribute, the method continues to a step 314 to calculate a privacy score for the target. As may be appreciated, a privacy score, as utilized herein, incorporates both a relative sensitivity value of the attribute and a relationship component with a target under inspection. In embodiments, a privacy score is the sum of all attribute scores for a particular target. At a next step 316, the method calculates a privacy index. In embodiments, a privacy index is a privacy score normalized to a range of approximately 0 to 100. In other embodiments, a privacy index is a privacy score normalized to a range of approximately 0 to 10. As such, a lower index indicates a lower risk of privacy exposure whereas a higher index indicates a higher risk of privacy exposure. At a next step 318, the method determines whether a target under inspection is a last target. If the method determines at a step 318 that the target under inspection is not the last target, the method continues to a step 302 to select another target. In this manner, the method iterates until all members (or targets) of a group are inspected. If the method determines at a step 318 that the target under inspection is the last target, the method continues to a step 206.
FIG. 4 is an illustrative representation of a graphical user interface (UI) 400 utilized for managing privacy settings for a social network in accordance with embodiments of the present invention. In particular, FIG. 4 is an illustrative embodiment of UI 114 (FIG. 1). It is noted that this illustration is presented for clarity in understanding embodiments of the present invention and should not be construed as limiting with respect to layout, design, color, or content. Indeed, any number of UIs may be presented which may be enabled for embodiments described herein. As illustrated, UI 400 may include privacy bar 402. Privacy bar 402 may be configured to indicate privacy settings relative to a continuum. In some embodiments, scroll bar 404 may be dragged only to recommended settings indicator 406. Upon dragging scroll bar 404 to recommended settings indicator 406, a user's privacy settings will be changed to reflect the recommended settings.
In some embodiments, UI 400 may include privacy graph 408. Privacy graph 408 may be utilized to easily indicate relative strength of privacy settings. In this example, privacy graph 408 indicates a privacy index of 30 out of 100, which is on a lower end of privacy indices. As noted above, in embodiments, a privacy index is a privacy score normalized to a range of approximately 0 to 100. In other embodiments, a privacy index is a privacy score normalized to a range of approximately 0 to 10. Privacy graph 408 may be further configured, in some embodiments, with color indicators indicating levels of risk. In one embodiment, red indicates a high level of risk and green indicates a low level of risk.
Further illustrated are current privacy settings 410 and recommended privacy settings 420. Privacy settings may include any number of attributes for a social network model. For example, business data attribute 412 is a description and business data attribute 414 is a time period. A checked attribute such as attribute 412 indicates that the attribute is not shared while a non-checked attribute such as attribute 414 indicates that the attribute is shared. In some embodiments, a checked attribute is shared and a non-checked attribute is not shared. Thus, checking or non-checking is merely an indication of whether or not an attribute is shared and should not be construed as limiting. In some embodiments, recommended privacy settings 420 include checked attributes such as attribute 422 which are not checked in current privacy settings. In some embodiments, recommended privacy settings 420 included non-checked attributes such as attribute 424 which are also non-checked in current privacy settings. In this manner, a user may quickly and easily determine which attributes have the same privacy settings between current and recommended privacy settings. In some embodiments, a user may select a subset of recommended privacy settings by checking or un-checking attributes on the UI.
While this invention has been described in terms of several embodiments, there are alterations, permutations, and equivalents, which fall within the scope of this invention. It should also be noted that there are many alternative ways of implementing the methods and apparatuses of the present invention. Furthermore, unless explicitly stated, any method embodiments described herein are not constrained to a particular order or sequence. Further, the Abstract is provided herein for convenience and should not be employed to construe or limit the overall invention, which is expressed in the claims. It is therefore intended that the following appended claims be interpreted as including all such alterations, permutations, and equivalents as fall within the true spirit and scope of the present invention.
