Abstract:
The shortcomings of the prior art are overcome and additional advantages are provided by securing display of sensitive messages to prevent third parties from viewing sensitive content. For one or more incoming messages designated as sensitive, substitute content to be displayed in place of sensitive content is received from a message recipient. Alternatively or additionally, an indicia to be displayed with any incoming message designated as sensitive is received from the message recipient. A message having sensitive content is designated as sensitive by a sender, a recipient, or an intermediate system. Upon receipt of a message designated as sensitive, a message window is displayed that includes substitute content different from the sensitive content. The substitute content includes an indicia that the sensitive content is not displayed.

       BACKGROUND OF THE INVENTION 
       [0002]    1. Field of the Invention 
         [0003]    The present invention relates generally to electronic messaging and, more specifically, to methods and computer program products for securing display of instant message and email content to prevent third parties from viewing sensitive content. 
         [0004]    2. Description of Background 
         [0005]    Various software programs exist for providing electronic messaging functionality. For example, in response to an incoming instant message, an Internet browser may cause a pop-up window to appear on a recipient&#39;s computer screen. The pop-up generally displays all or a portion of the contents of an instant message. From time to time, the recipient may receive a sensitive or private instant message while away from their computer screen or while a third party is present. Depending on the contents of the message, the recipient may experience subsequent job loss or, at the very least, significant embarrassment. 
         [0006]    Existing techniques for protecting the privacy of messages include keeping message content hidden or minimized until an explicit request is issued to view the message, displaying the message content in garbled form until a recipient interacts with an instant messaging or email program, or forcing the recipient to authenticate before displaying the message. For example, U.S. Publication No. 2003/0023695 describes a system for sending secure messages whereby the recipient, as well as possible third party onlookers, are presented with a visual indicator that the message includes secure content to be retrieved. If the recipient wishes to view the secure content, the message must be authenticated using procedures that are determined by the message sender. Unfortunately, none of the aforementioned prior art techniques are suitable where the message recipient is in the presence of a third party. These techniques are conspicuous, causing the third party to speculate as to why the message recipient is attempting to conceal the contents of the incoming message. 
         [0007]    Accordingly, what is needed is a technique for securing display of message content while, at the same time, not providing an indication to any observing third party that a sensitive or private message has been received. 
       SUMMARY OF THE INVENTION 
       [0008]    The shortcomings of the prior art are overcome and additional advantages are provided by securing display of sensitive messages to prevent third parties from viewing sensitive content. For one or more incoming messages designated as sensitive, substitute content to be displayed in place of sensitive content is received from a message recipient. Alternatively or additionally, an indicia to be displayed with any incoming message designated as sensitive is received from the message recipient. A message having sensitive content is designated as sensitive by a sender, a recipient, or an intermediate system. Upon receipt of a message designated as sensitive, a message window is displayed that includes substitute content different from the sensitive content. The substitute content includes an indicia that the sensitive content is not displayed. 
         [0009]    Computer program products corresponding to the above-summarized methods are also described and claimed herein. 
         [0010]    Additional features and advantages are realized through the techniques of the present invention. Other embodiments and aspects of the invention are described in detail herein and are considered a part of the claimed invention. For a better understanding of the invention with advantages and features, refer to the description and to the drawings. 
       TECHNICAL EFFECTS 
       [0011]    As a result of the summarized invention, technically we have achieved a solution wherein, upon receipt of a message designated as sensitive and including original content, a message window is displayed that includes substitute content different from the original content. The substitute content includes an indicia that the original content is not displayed.

       DETAILED DESCRIPTION OF THE INVENTION 
       [0016]      FIG. 1  illustrates an exemplary method for securing display of sensitive messages received from third parties. These messages may include instant messages, email messages, other types of electronic messages, or various combinations thereof. The procedure commences at block  101  or block  103 . Only one block of blocks  101  and  103  may be performed, or blocks  101  and  103  may both be performed. If blocks  101  and  103  are both performed, these blocks can be performed substantially simultaneously or in any sequence. 
         [0017]    At block  101 , a message recipient specifies substitute content to be displayed in place of sensitive content for any incoming message designated as sensitive. Illustratively, the recipient specifies substitute content that is not readily discernable as such by potential third party observers. The substitute content may, but need not, be selected in accordance with the recipient&#39;s immediate surroundings and may, but need not, represent a phrase or sentence that would be innocuous, irrelevant, trivial, vague, or meaningless to third party observers. For example, if the recipient is working in a large office complex, the recipient may specify substitute content such as “Where is Charlie&#39;s office located?”, “I can&#39;t find that invoice”, or “How is your project coming along?”. These phrases would be unlikely to arouse the attention of onlookers in an office environment. On the other hand, if the recipient is working at home, the recipient may specify different substitute content such as “How about those Yankees?” or “The Beerworth Proposal needs more work” so as to not arouse the attention of family members. 
         [0018]    At block  103 , a message recipient specifies an indicia to be displayed with any incoming message designated as sensitive. Illustratively, the recipient specifies an indicia that is not readily discernible as such by potential third party observers. For example, using an indicia in the form of a pop-up window with a bright red background might be too conspicuous in many real-world situations, as would displaying a message in the form of random characters or symbols. Adopting either of these examples, an onlooker would readily discern that a recipient is receiving a sensitive message. On the other hand, italicizing one or more characters or punctuation marks of a displayed message, displaying the message using a different font or font size, or transposing two letters in a word, all represent suitable indicia to be displayed with any incoming message designated as sensitive. 
         [0019]    At block  105 , a message having sensitive content to be secured from third parties is designated as sensitive by a message sender, a message recipient, or an intermediate system. For example, a message recipient could specify that all messages originating from a specific email address or instant messaging screen name be designated as sensitive, or an intermediate system such as an email server at an internet service provider can designate some or all messages processed by the intermediate system as sensitive. Next, at block  107 , an incoming electronic message is received. This message may represent, for example, an email message, an instant message, another type of electronic message, or any of various combinations thereof. 
         [0020]    A test is performed at block  109  to ascertain whether or not the received message was designated as sensitive by at least one of the message sender, the message recipient, or an intermediate system. If not, the procedure progresses to block  113  where a message window is displayed that includes original content from the received message. The procedure then loops back to block  107 . The affirmative branch from block  109  leads to block  111  where a message window is displayed that includes substitute content different from the sensitive content. If block  101  was previously performed, this substitute content was specified by the message recipient. Otherwise, substitute content may be automatically generated or retrieved for display at block  111 . 
         [0021]    The procedure advances to block  115  where a test is performed to ascertain whether or not an indication is received from the message recipient indicating that the sensitive content is to be displayed. This indication may be received in the form of the message recipient clicking on one or more characters of the message window containing substitute content, highlighting one or more characters of the message window, entering a predetermined key sequence, right-clicking to cause a pop-up menu to appear with an option “display original message”, or performing another action. If an indication is not received, the procedure loops back to block  111 . The affirmative branch from block  115  leads to block  117  where a message window is displayed that includes the sensitive content as present in the received incoming electronic message. The procedure then loops back to block  107 . 
         [0022]      FIGS. 2A and 2B  set forth an illustrative example by which display of sensitive information is secured using the procedures of  FIG. 1 . The example commences at block  201  where Alice composes an instant message as follows: “Bob, we really need to talk about your problem with commitment”. Assume that Bob has been engaged to Alice for the past five years with no wedding date planned. Further assume that Bob is working in a busy office environment presently surrounded by several co-workers gazing at a presentation on Bob&#39;s computer screen. If these co-workers were to view Alice&#39;s instant message to Bob, this would cause Bob much embarrassment and might even lead to Bob&#39;s unemployment. 
         [0023]    At block  203 , Alice designates her instant message as including sensitive content. Next, Alice sends the instant message to Bob (block  205 ). Bob receives Alice&#39;s instant message (block  207 ). However, using the approach described in connection with  FIG. 1 , Bob&#39;s computer screen displays an instant message pop-up window including substitute content “Can you tell me where Charlie sits?” (block  209 ). Bob observes that the instant message pop-up window includes a sensitive message indicia in the form of an italicized question mark (block  211 ). Accordingly, Bob composes an instant message response: “I&#39;m in a meeting, will get back to you soon” (block  213 ). Bob sends the composed instant message to Alice (block  215 ). 
         [0024]    After some time has elapsed, Bob&#39;s meeting is finally over and Bob&#39;s co-workers return to their respective offices (block  217 ). Bob control-clicks over the italicized question mark in the message pop-up window (block  219 ). Alice&#39;s original message appears in the pop-up window: “Bob, we really need to talk about your problem with commitment” (block  221 ). 
         [0025]    The capabilities of the present invention can be implemented in software, firmware, hardware or some combination thereof. As one example, one or more aspects of the present invention can be included in an article of manufacture (e.g., one or more computer program products) having, for instance, computer usable media. The media has embodied therein, for instance, computer readable program code means for providing and facilitating the capabilities of the present invention. The article of manufacture can be included as a part of a computer system or sold separately. 
         [0026]    Additionally, at least one program storage device readable by a machine, tangibly embodying at least one program of instructions executable by the machine to perform the capabilities of the present invention can be provided. 
         [0027]    The diagrams depicted herein present illustrative examples. There may be many variations to these diagrams or the steps (or operations) described therein without departing from the spirit and scope of the invention. For instance, the steps may be performed in a differing order, or steps may be added, deleted or modified. All of these variations are considered a part of the claimed invention. 
         [0028]    While the preferred embodiment to the invention has been described, it will be understood that those skilled in the art, both now and in the future, may make various improvements and enhancements which fall within the scope of the claims which follow. These claims should be construed to maintain the proper protection for the invention first described.
