## Background
CROSS-REFERENCE TO RELATED APPLICATION
This application is a Continuation of U.S. application Ser. No. 13/747,879, filed on Jan. 23, 2013, the disclosure of which is incorporated herein in its entirety by reference.


TECHNICAL FIELD
The field generally relates to systems and methods for obfuscation during communications and, in particular, to systems and methods for temporary obfuscation during collaborative communications.
BACKGROUND
Sometimes during an electronic communication, such as an instant messaging or email conversation, a section of text or media in the communication may be inappropriate for certain audiences. If the recipient or sender wishes to alert the other party to the communication of, or otherwise hide the content, there are presently no effective means for accomplishing this task. As a result, a user is typically resigned to closing a chat window or message thread, and/or deleting the history of the communication including the potentially inappropriate subject matter.
Some known methods for addressing sensitive information relate to allowing a user to unobscure selected pages of an online document upon receipt of authentication information, but do not relate to obscuring an entire or part of a message in a collaborative communication, such as an instant message, or a message sent via, for example, a smartphone, using short message service (SMS) or multimedia messaging service (MMS). Other known methods relate to encryption and decryption, where users can encrypt messages, and a receiver identified as an authorized user can decrypt and read the messages.
None of the known methods for obfuscating electronic content provide a temporary obfuscating method for collaborative communications, which can inform recipients of the sensitivity of the content, while still allowing the recipients to easily lock, unlock and view the sensitive content.

DETAILED DESCRIPTION OF EXEMPLARY EMBODIMENTS
Exemplary embodiments of the invention will now be discussed in further detail with regard to systems and methods for obfuscation during communications and, in particular, to systems and methods for temporary obfuscation during collaborative communications. This invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein.
Disclosed are systems and methods for obfuscating sensitive material temporarily until unlocked by the receiver. Referring to FIG. 1, a method for temporary obfuscation during collaborative communications implemented on a sender side, according to an embodiment of the present invention is shown. At block 101, the sender enters a comment or media in a collaborative communication that could be sensitive. At block 103, the content is marked as sensitive. According to embodiments of the present invention, content may be marked as sensitive by, for example, highlighting the content, highlighting the content and performing a mouse operation, such as a right click, allowing a sender to click on “sensitive” as an option, highlighting the content and clicking on a menu option from a toolbar to mark the content as sensitive, and/or tagging all or part of the comment or media with meta data. According to an embodiment, as an alternative, or in addition to marking the sensitive content by highlighting the sensitive content, the sender could choose a flag, such as, for example, an all or nothing flag, which, for example, marks all graphics sent, and/or marks all messages including certain meta data, keywords or phrases (e.g., “confidential”) as potentially sensitive. In addition, content may be deemed sensitive based on certain predetermined preference rules such as time of day the message is being sent. According to an embodiment, when content is marked as sensitive on the sender side, the content remains visible on the sender side, and will be obfuscated on the receiver side. However, it should be noted that embodiments of the present invention also allow the marked content to be obfuscated on the sender side, if, for example, criteria (e.g., preference rules) for obfuscating the content is met on the sender side. For example, a sender can send some content that certain individuals should not see. The content may also be obfuscated on the sender side if, for example, those individuals enter into the proximity of the sender's device, the device detects that others are around the device, and then obfuscates the content from the sender's device.
At block 105, the sender optionally provides details, which will be transmitted to the recipient, as to why, where and/or when the content is sensitive. According to embodiments of the present invention, such details may include, for example, the nature of the message, for who the message might be sensitive (e.g., customers, etc.), a time period when the content is sensitive (e.g., from 8 am-5 pm not sensitive, from 5 pm on, it could be sensitive, location where allowed (e.g., Bob cannot view the message while at the customer headquarters and/or in a public place). According to an embodiment, some of the details may be automatically generated, if, for example, the sensitivity is based on the use of certain keywords or key phrases, or based on predetermined preference rules for which a pre-formatted details message can be used. At block 107, the message including the sensitive content and details is sent via a network, at block 109, the receiver's system intercepts the message including the sensitive information and details, and at block 111, the receiver's system obfuscates the sensitive content and provides the additional information (if any provided) to the user. In accordance with an embodiment, the receiver's system may provide the receiver with a specialized notification that the message includes sensitive content. The specialized notification may be, for example, in the form of a sound byte. According to an embodiment, at block 113, the receiver can request additional information about the content if the receiver determines that there was not enough information provided. At block 115, the receiver determines if he/she wishes to open/view the sensitive information, and opens/views the sensitive information. According to an embodiment, opening/viewing the sensitive information can be performed by, for example, a right-click mouse operation. According to embodiments of the present invention, an obfuscated message or image can be, for example, hidden from view, grayed out, blacked out with an icon specifying that the content is locked, mosaicked or otherwise garbled to hide the content but still be present to tell the user that the content is there.
An example of a sender side implementation may be a situation where sender sends an instant message to receiver. Sender knows that receiver is on assignment at a customer and therefore confidential material sender is sending should not be viewed in front of any of the customers. Sender, therefore, marks the content as sensitive and sends an instant message. Receiver receives the message and the sensitive information is obfuscated on the receiver side until the receiver performs the necessary actions (e.g., a right-click mouse operation) to reveal the sensitive information.
Referring to FIG. 2, a method for temporary obfuscation during collaborative communications implemented on a receiver side, according to an embodiment of the present invention is shown. At block 201, a receiver receives a message that was not marked as including sensitive content (e.g., did not use implementations as set forth in FIG. 1). At block 203, the receiver makes a determination that all or part of the message is sensitive. At block 205, the receiver marks the message or part of the message as sensitive using the same or similar techniques to those described in connection with block 103 in FIG. 1, such as highlighting the content and/or tagging all or part of the content with meta data. According to an embodiment, as an alternative or in addition to a receiver making a determination as to whether the content or message is sensitive and a receiver marking the sensitive content, the receiver could choose an all or nothing flag, which, for example, marks all graphics received, and/or marks all messages including certain meta data, keywords or phrases (e.g., “confidential”) as potentially sensitive. At block 207, it is queried whether there are any preference rules. If the answer is no at block at 207, the marked content is obfuscated at block 209. As described above, obfuscated could mean, for example, hidden from view, grayed out, blacked out with an icon specifying that the content is locked, and/or mosaicked or otherwise garbled. According to an embodiment, the mode of obfuscation can be set up by a user prior to receiving messages. In the receiver side implementation case, according to an embodiment, the content deemed sensitive by the receiver will be obfuscated on the receiver side, but not on the sender side.
According to an embodiment, prior to obfuscation, the system may perform a check to determine whether any preference rules have been implemented (as per block 207), which may put conditions on whether content is obfuscated. For example, preference rules may be based on location, time, and/or proximity of other people. Example preference rules include, for example, obfuscate messages while at home, but not in the office, obfuscate the messages after 5 pm, only show the messages if no other people are in the proximity, and keep the message obfuscated until a receiver unlocks it. According to an embodiment, the preference rules can be set up by a user prior to receiving messages. It the answer is yes at block 207, the system applies the preference rules at block 211 which may result in obfuscation at block 209, or no obfuscation at block 213.
In connection with a preference rule based on proximity of other people, the devices on which the messages are received, processed and/or displayed can include hardware and/or software to detect multiple devices in the area using, for example, BLUETOOTH type technology, in turn, inferring that there are multiple people in the area, or to detect multiple people in the proximity with biometric sensors, such as eye detectors, cameras, voice detectors, such as microphones, heat sensors, or other sensors that can detect human presence. Also, preference rules based on location may be tied in with information on location provided by global positioning systems, Wi-Fi and/or Wi-Fi type connections. According to embodiments of the present invention, preference rules are applied whether looking at a message in real time, or reviewing the history of a message that occurred in the past. For example, if a user is reviewing a message that occurred in the past during times or at a location where preference rules state that the sensitive content be obfuscated, the sensitive content from the past message is obfuscated according to those preference rules.
Referring, for example, to FIGS. 3A-3C, which are screen shots for illustrating implementation of an embodiment of the present invention, a sample collaborative messaging scenario is shown between two individuals (e.g., “Bob” and “Sue”). Referring to FIG. 3A, the first screen shot 300 shows potentially sensitive content 301 coming from Sue. The potentially sensitive content can include, but is not necessarily limited to, an animated gif, still images, words or phrases, confidential information, etc. In this example, we will assume that the sensitive content 301 is an animated gif, Bob is in a public place with many people nearby and does not want people passing by to see this type of graphic. According to embodiments of the present invention, Bob or Sue can mark the graphic as potentially sensitive. Once marked, Bob may see an image 311 such as what is shown in screen shot 310 in FIG. 3B. According to an embodiment, referring to the screen shot 320 in FIG. 3C, Bob can move his cursor or pointer over the image 311 to reveal further information 321 about the sensitive content and learn more about why this content is obfuscated. In addition, by, for example, clicking his mouse on the image 311, Bob can unlock the potentially sensitive gif once he is no longer in the public place and/or no other people are in the area. Sue's version of the conversation shows the sensitive content. However, as described, above, embodiments of the present invention also allow the marked content to be obfuscated on Sue's side, if, for example, criteria (e.g., preference rules) for obfuscating the content is met on Sue's side.
Referring to FIG. 4, which is a high-level diagram of a system for temporary obfuscation during collaborative communications according to an exemplary embodiment of the invention, a system 400 includes messaging devices 401 and 421 for users A and B, respectively. The messaging devices 401, 421 can be, for example, desktop computers, laptops, mobile phones, such as smartphones, personal digital assistants (PDAs), or any other device capable of receiving and sending collaborative messages, such as instant messages or text and multimedia messages sent using SMS and/or MMS. Depending on the situation, users A and B can be either senders or receivers of messages, or both. For purposes of discussion and explanation, user A will be referred to as the sender, and user B as the receiver, but are not limited thereto. The messaging devices are connected to each other via a network 450, which can include but is not limited to, for example, a local area network (LAN), wide area network (WAN), cellular network, satellite network and the Internet.
Each messaging device 401 and 421 is equipped with the same or similar modules for performing the processes associated with the embodiments of the present invention. For example, each messaging device includes one or more input devices 403, 423, which interface with a user interface 405, 425, such as a graphical user interface (GUI). The input devices 403, 423 include, for example, virtual and/or physical keyboards, mice, touchscreens, and/or voice input devices. Each device 401, 421 further includes a content module 407, 427, a message analyzer module 409, 429, a preference rule module 411, 431, a detection module 413, 433 and one or more sensors 415, 435.
According to an embodiment, the sender (e.g., user A) enters a comment or media via input device 403 and user interface 405 that could be sensitive. Using the input device 403, user A is able to instruct the system to mark the content as sensitive by, for example, highlighting the content and selecting a menu option to mark the content as sensitive. User A's selection of sensitive content is transmitted to content module 407. According to an embodiment, as an alternative, or in addition to the user instructing the system to mark the sensitive content, the message analyzer module 409 connected to the content module 407 analyzes the message to determine the presence of any graphics and/or meta data, keywords or phrases. If the message analyzer module 409 finds any graphics, meta data, keywords or key phrases, the message analyzer module 409 communicates this result to the content module 407 to apply, for example, an all or nothing flag, which marks all graphics, and/or marks all messages or parts of a message including certain meta data, keywords or phrases as potentially sensitive. In addition, depending on certain pre-defined settings, the content module 407 can receive input from the preference rules module 411 that instructs that the message or parts of the message be deemed sensitive based on certain predetermined preference rules such as, for example, the time of day the message is being sent. According to an embodiment, the content module 407, based on input from the user, the message analyzer module 409 and/or the preference rule module 411, marks content in the message as sensitive on user A's side. The content remains visible on user A's side, and will be obfuscated on user B's side. However, as described above, embodiments of the present invention allow the marked content to also be obfuscated on user A's side, if, for example, criteria (e.g., preference rules) for obfuscating the content is met on user A's side.
User A can provide details via the input device 403, which will be transmitted to user B, as to why, where and/or when the content is sensitive. According to embodiments of the present invention, as described above, such details may include, for example, the nature of the message, for who the message might be sensitive, a time period when the content is sensitive, and/or location where message viewing is allowed. As stated above, according to an embodiment, some of the details may be automatically generated by the content, message analyzer and/or preference rules modules 407, 409, 411, if, for example, the sensitivity is based on the use of certain keywords or key phrases, or based on predetermined preference rules for which a pre-formatted details message can be used. The marked message and explanations, if any, are sent to user B's device 421 via the network 450. The device 421 receives the marked message and explanations at the content module 427, which can obfuscate the sensitive content, alert user B of the sensitivity of the content, and provide the additional information (if any provided) to user B via the user interface 425. According to an embodiment, user B can request additional information from user A about the content via the user interface 425 if user B determines that there was not enough information provided about the sensitivity. If user B determines that he/she wishes to open/view the sensitive information, user B opens/views the sensitive information via user interface 425 and input device 423.
If user B receives a message that was not marked as sensitive, user B can make a determination that all or part of the message is sensitive, and instruct the system to mark the message or part of the message as sensitive using the same or similar techniques to those described in connection with user A instructing the system to mark a message. Also, as an alternative or in addition to user B instructing the system to mark the sensitive content, the message analyzer module 429 connected to the content module 427 analyzes the message to determine the presence of any graphics and/or meta data, keywords or phrases. If the message analyzer module 429 finds any graphics, meta data, keywords or key phrases, the message analyzer module 429 communicates this result to the content module 427 to apply, for example, an all or nothing flag, which marks all graphics, and/or marks all messages or parts of a message including certain meta data, keywords or phrases as potentially sensitive. The marked content can be obfuscated by the content module 427. According to an embodiment, the mode of obfuscation can be set up by user B prior to receiving messages.
According to an embodiment, prior to obfuscation, the preference rule module 431 can perform a check to determine whether any preference rules have been implemented, which may put conditions on whether content is obfuscated. For example, as described above, preference rules may be based on location, time, and/or proximity of other people. As described above, example preference rules include, for example, obfuscate messages while at home, but not in the office, obfuscate the messages after 5 pm, only show the messages if no other people are in the proximity, and keep the message obfuscated until a receiver unlocks it. According to an embodiment, the preference rules can be set up by user B prior to receiving messages.
In connection with a preference rules based on proximity of other people and/or location, the devices 401, 421 on which the messages are received, processed and/or displayed include a detection module 413, 433 to detect location, multiple devices and/or multiple people in an area using, for example, sensors 415, 435. The sensors 415, 435 can include BLUETOOTH type technology sensors or receivers detecting multiple user devices in the area to infer multiple people in an area, biometric sensors, such as eye detectors, cameras, voice detectors, such as microphones, heat sensors, or other sensors that can detect human presence, and GPS, Wi-Fi or Wi-Fi type devices which can determine location based on a GPS signal, Wi-Fi or Wi-Fi type connection. As stated above, according to embodiments of the present invention, preference rules are applied whether looking at a message in real time, or reviewing the history of a message that occurred in the past.
