## Background
The specification relates to social networks. In particular, the present specification relates to privacy settings on social networks. The present specification also relates to generating and sending a notification to a first social network user when the user's privacy settings of the first social network differ from the user's privacy settings in at least one other social network.
BACKGROUND
Social networks are becoming an increasingly popular way for people to stay connected. This increasing popularity of social networks has given rise to social network services that have developed various ways users of the social network can communicate and share information. Users within a social network can send each other messages, view other users' activities and share personal information, including personal photographs and videos. Social networking services can provide a forum for users to remain in close contact despite geographic distance or uncoordinated schedules. Social network users are typically able to adjust the amount and type of information they choose to share and how and with whom that information is shared. However, for users belonging to multiple social networks, it may be difficult for the users to monitor the privacy settings of each social network, remember the different privacy settings of each social network, or even realize that each social network's privacy settings are different.
SUMMARY OF THE INVENTION
The deficiencies and limitations of the prior art at least in part are overcome by providing a system and method for notifying a first social network user when one or more of the user's privacy settings differ from the user's privacy settings in at least one other social network.
A system and method are provided for generating a notification of privacy settings difference. In one embodiment the system includes a request receiver engine, privacy settings retrieval engine, privacy settings differentiator engine, differentiation display engine and an optional privacy settings adjustment engine. The request receiver engine for receives a request. The privacy settings retrieval engine receives a first set of privacy settings of a user from a first social network and a second set of privacy settings of the user from at least one other social network. The privacy settings differentiator engine compares the privacy settings of the first social network to those of the of the at least one other social network and, responsive to detecting a difference between the first set of privacy settings and the second set of privacy settings, prompts the differentiation display engine to generate a notification. The notification is sent to the user for display and includes an indication that the difference has been detected.
In one embodiment, the request is the user's login request that is sent to the first social network. In another embodiment, the request is the user's request to edit one or more privacy settings of the first social network. In yet another embodiment, the request is the user selecting a button or hypertext link on the first social network. In one embodiment, the difference exists when the privacy setting of the first set of privacy settings is less restrictive than the privacy setting of the second set of privacy settings.
The notification may include a variety of information and features. In one embodiment, the notification identifies at least one other social network having the detected difference from the first social network. In another embodiment, the notification includes the detected difference between the first set of privacy settings and the second set of privacy settings. In one embodiment, the notification allows the user to request to view, or edit, one or more of the privacy settings of the first social network. In one such embodiment, the privacy settings adjustment engine receives the user's request to view, or edit, the privacy settings of the first social network; and sends the user to a webpage on the first social network where the privacy settings are typically displayed, or edited. In another such embodiment, the privacy settings adjustment module receives the user's request to edit and one or more edits to the user's privacy settings of the first social network; and updates the privacy settings of the first social network according to the edits received from the user.

In the following description, for purposes of explanation, numerous specific details are set forth in order to provide a thorough understanding of the embodiments. It will be apparent, however, to one skilled in the art that the embodiments can be practiced without these specific details. In other instances, structures and devices are shown in block diagram form in order to avoid obscuring the embodiments. For example, the present embodiments are described in one embodiment below with reference to user interfaces and particular hardware. However, the present embodiments apply to any type of computing device that can receive data and commands, and any peripheral devices providing services.
Reference in the specification to “one embodiment” or “an embodiment” means that a particular feature, structure, or characteristic described in connection with the embodiment is included in at least one embodiment. The appearances of the phrase “in one embodiment” in various places in the specification are not necessarily all referring to the same embodiment.
Some portions of the detailed descriptions that follow are presented in terms of algorithms and symbolic representations of operations on data bits within a computer memory. These algorithmic descriptions and representations are the means used by those skilled in the data processing arts to most effectively convey the substance of their work to others skilled in the art. An algorithm is here, and generally, conceived to be a self consistent sequence of steps leading to a desired result. The steps are those requiring physical manipulations of physical quantities. Usually, though not necessarily, these quantities take the form of electrical or magnetic signals capable of being stored, transferred, combined, compared, and otherwise manipulated. It has proven convenient at times, principally for reasons of common usage, to refer to these signals as bits, values, elements, symbols, characters, terms, numbers or the like.
It should be borne in mind, however, that all of these and similar terms are to be associated with the appropriate physical quantities and are merely convenient labels applied to these quantities. Unless specifically stated otherwise as apparent from the following discussion, it is appreciated that throughout the description, discussions utilizing terms such as “processing” or “computing” or “calculating” or “determining” or “displaying” or “comparing” or identifying” or the like, refer to the action and processes of a computer system, or similar electronic computing device, that manipulates and transforms data represented as physical (electronic) quantities within the computer system's registers and memories into other data similarly represented as physical quantities within the computer system memories or registers or other such information storage, transmission or display devices.
The present embodiments also relate to an apparatus for performing the operations herein. This apparatus may be specially constructed for the required purposes, or it may comprise a general-purpose computer selectively activated or reconfigured by a computer program stored in the computer. Such a computer program may be stored in a computer readable storage medium, such as, but is not limited to, any type of disk including floppy disks, optical disks, CD-ROMs, and magnetic disks, read-only memories (ROMs), random access memories (RAMs), EPROMs, EEPROMs, magnetic or optical cards, flash memories including USB keys with non-volatile memory or any type of media suitable for storing electronic instructions, each coupled to a computer system bus.
The embodiments can take the form of an entirely hardware embodiment, an entirely software embodiment or an embodiment containing both hardware and software elements. A preferred embodiment is implemented in software, which includes but is not limited to firmware, resident software, microcode, etc.
Furthermore, one embodiment can take the form of a computer program product accessible from a computer-usable or computer-readable medium providing program code for use by or in connection with a computer or any instruction execution system. For the purposes of this description, a computer-usable or computer readable medium can be any apparatus that can contain, store, communicate, propagate, or transport the program for use by or in connection with the instruction execution system, apparatus, or device.
A data processing system suitable for storing and/or executing program code will include at least one processor coupled directly or indirectly to memory elements through a system bus. The memory elements can include local memory employed during actual execution of the program code, bulk storage, and cache memories which provide temporary storage of at least some program code in order to reduce the number of times code must be retrieved from bulk storage during execution.
Input/output or I/O devices (including but not limited to keyboards, displays, pointing devices, etc.) can be coupled to the system either directly or through intervening I/O controllers.
Network adapters may also be coupled to the system to enable the data processing system to become coupled to other data processing systems or remote printers or storage devices through intervening private or public networks.

In the illustrated example, the notification 604 notifies the first social network user that the user's first social network uses less restrictive privacy settings than the user's other social network 101b/101n; however, as previously discussed, the notification 604 can contain different/other information. According to one embodiment, the notification requires user to confirm the receipt of the notification 604 by using the user input device 608 to select a confirmation button 610. According to one embodiment, the notification 604 gives the user the option to edit the user's privacy settings by linking them to the privacy settings edit page, which is accomplished by the “Edit” button 612 in the illustrated embodiment.
FIG. 7 is a graphic representation of a user interface 700 displaying a notification 703 on a separate social networking page 702. In the illustrated embodiment, the notification 703 notifies the user that the first social network's 101a privacy settings differ from those on one or more of the user's other social networks 101b, 101n. As previously discussed, according to one embodiment, the notification 703 can include information about which privacy settings differ and what those settings are. In the illustrated embodiment, table 704 includes information about which privacy settings differ and what each of those settings is. Table 704 includes column 706, which contains the one or more features associated with privacy settings that differ between the user's first social network 101a and at least one other social network 101b, 101n according to one embodiment. Table 704, according to one embodiment, includes column 708, which contains the first social network's 101a privacy settings associated with each of the one or more features in column 706. Table 704, according to one embodiment, includes column 710, which contains the privacy settings associated with each of the one or more features in column 706 in a first different social network 101b/101n to which the user also belongs. Table 704, according to one embodiment, includes column 712, which contains the privacy settings associated with each of the one or more features in column 706 in a second different social network 101b/101n to which the user also belongs. In one embodiment, the user is notified which privacy settings are different and how those settings are different by reading across a row in table 704. For example, row 705 notifies the user that the privacy setting for the user's “First/Last Name” varies because the user's first social network has a privacy setting that makes that data and information public, “Other Social Network 1” has a different setting, and “Other Social Network 2's” privacy setting matches that of the first social network in one embodiment. In the illustrated example, box 714 is left empty. In one embodiment, a box is left empty when the privacy setting for that feature on that social network matches the privacy setting for that feature on the user's first social network.
