## Background
CROSS-REFERENCE TO RELATED APPLICATIONS
This application is a Continuation of U.S. application Ser. No. 13/172,894, filed on Jun. 30, 2011.


BACKGROUND
The embodiments disclosed within this specification relate to electronic messaging systems. More particularly, the embodiments relate to selective delivery of content via electronic mail (email).
Email systems are commonly used to facilitate the exchange of content among users, such as information presented in a body of an email or electronic files attached to an email. To mitigate the risk of such documents from being intercepted and viewed by unscrupulous parties, such documents oftentimes are encrypted. For example, documents oftentimes are encrypted with password protection. When a recipient receives such a document, the recipient usually is required to enter a password in order to view the document. Notwithstanding the level of security provided by the use of password protection, security continues to be a significant concern in those organizations that use email to facilitate the exchange of information.

The present invention relates to the sending of content, such as information in the body of an electronic mail (email) or an attachment to an email. More particularly, the present invention provides functionality that enables a user to provide content with an email, and send different versions of the email to different groups of recipients. For example, a first group of recipients can be sent a first email having the content, and such recipients can be provided access to the content. A second group of recipients can be sent a second email, which is different than the first email, that does not include the content. The second email can provide information to the second group of users that pertains to the first email. For example, within the second email, contact information can be provided to indicate to the second group of recipients who those recipients may contact to discuss information to which the email pertains. Further, the second email can indicate a suitable time when the second group of recipients may contact the person to discuss and/or receive information regarding subject matter associated with the first email. In one aspect, for example when there are many users identified in the second group of recipients, the email can be sent to different users, or groups of users, at different times.
FIG. 1 is a block diagram illustrating a system 100 for sending an email 120 comprising content 122 in accordance with one embodiment of the present invention. The system 100 can include a plurality of email clients 102, 104, 106, each of which are communicatively linked to a communication network 110. The communication network 110 can comprise a local area network (LAN), a wide area network (WAN), the Internet, and/or any other communication system through which emails may be communicated. As those skilled in the art will appreciate, the email clients 102-106 can be executed on any suitable devices, for example on computers, personal digital assistance, mobile telephones, or the like.
In operation, via the email client 102, a user can configure a first email 120 to be sent to a plurality of recipients, for example users associated with email clients 104, 106. The email 120 can include content 122. Such content 122 can be information presented in the body of the email 120 or an attachment to the email 120. Information presented in the body of the email can include alphanumeric text, graphics, or any other type of information that may be included within the body of an email. An email attachment can be any electronic file that may be transferred as an attachment to an email. For example, an email attachment can be an electronic document, a file comprising computer program code, etc. The first email 120 can be sent via an email server 130. Email servers are well known to those skilled in the art.
A user composing the email 120 can identify one or more recipients (a first group of recipients) to receive the content 122 and one or more recipients (a second group of recipients) that are not to receive the content 120. Such recipients can be those recipients deemed to be trusted with the content 122 sent with the email 120. As used herein, a recipient is a person to whom an email is directed. For the first group of recipients that are identified to receive the email content 122, the email 120 can be sent to those recipients. In illustration, the email 120 can be sent to email accounts for the first group of recipients, and the email clients 104 can retrieve the emails 120 for presentation to such recipients.
For the second group of recipients identified to not receive the content 122, for example non-trusted recipients, a second email 140 can be automatically composed, either by the email client 102 or the email server 130, and communicated to such recipients. In illustration, the second email 140 can be sent from the email client 102 to email accounts associated with the second group of recipients and the email clients 106 can retrieve the emails 140 for presentation to such recipients.
In another embodiment, rather than the email client 102 sending the second email 140 to the non-trusted recipients, trusted recipients who receive the first email 120 can elect to forward the email 120 to the non-trusted recipients. In illustration, when a trusted recipient chooses to forward the first email 120 to non-trusted recipients, the second email 140 can be automatically generated and sent to the non-trusted recipients in lieu of the first email 120. In one arrangement, any recipient to whom the first email is being forwarded can be considered a non-trusted recipient. In another arrangement, potential recipients of forwarded emails can be assigned security credentials. When the email 120 is to be sent to a recipient, the recipient's security credentials can be accessed. Based on the security credentials, a determination can be made as to whether the recipient is categorized as being trusted or being non-trusted. If the recipient is trusted, the first email 120 can be forwarded to the recipient. If the recipient is non-trusted, the second email 140 can be forwarded to the recipient. The second email 140 can be generated by the email client 104 of the user who chooses to forward the email, or by the email server 130. Moreover, the email client 104 or the email server 130 can determine whether a recipient of a forwarded email 120 is trusted or non-trusted.
The second email 140 need not include the content 122. Instead, the second email 140 can include information 142 that pertains to the first email 120. The information 142 can include contact information that indicates to the second group of recipients who may be contacted to discuss the email 140, or related matters. For example, if the content 122 is a new version of a computer program, the new version can be sent to only those users who are authorized to evaluate the new version. Nonetheless, via the email 140, other users can be informed that the new version of the computer program has been sent to those who will be evaluating it. Moreover, the email 140 can indicate to the other users who they may contact if they wish to participate in the evaluation process. In this regard, those wishing to participate may be asked to execute a confidentiality agreement prior to being given access to the computer program.
Further, the second email 140 can indicate a suitable time when the second group of recipients may contact the person to discuss and/or receive information to which the email 140 pertains. Notably, the recipients receiving the email 120 do not own or control the content 122. In this regard, other than the information provided in the second email 140, the second group of recipients will not be able to access the content 122, or any information related to the content 122, via the email 140.
In one aspect, for example when there are many users identified in the second group of recipients, the email 140 can be customized to indicate to a first subgroup of the users to contact the person at a first time, indicate to a second subgroup of the users to contact the person at a second time, indicate to a third subgroup of the users to contact the person at a third time, and so on. The subgroups can be defined in any suitable manner. For example, each of the recipients that are members of the second group of recipients can be assigned to a subgroup based on the recipient's respective level within an organizational hierarchy. In this regard, the second email 140 can be configured to automatically add a calendar entry pertaining to the information into respective electronic calendars of the second group of recipients.
Further, the second email 140 can be sent to different recipients, or subgroups of recipients, at different times. In illustration, recipients that are members of the second group of recipients can be classified into a plurality of subgroups. The email 140 can be sent to a first subgroup of recipients at first time, a second subgroup of recipients at a second time, and a third subgroup of recipients at a third time. Further the second email 140 can assign each subgroup of recipients a particular time at which to contact the person who is authorized to provide further information regarding the email 140. Thus, the risk of recipients inundating a person to be contacted in response to the email 140 being received can be minimized.
By controlling how the content 122 is distributed as described herein, the present invention mitigates the risk of unauthorized information leaks, thereby improving the security of electronic data.
FIG. 2 depicts a view 200 presented in an email client in accordance with another embodiment of the present invention. In the view 200, a user (e.g., an email sender) can be presented a number of options for composing an email, such as the email 120 of FIG. 1. At least one of the options can pertain to attaching an electronic file to the email so that the electronic file will be sent with the email. For example, an “Attach” selectable object 202 (e.g., a button or icon) can be presented in the view 200. The “Attach” selectable object 202 can be presented with text, graphics, or in any suitable manner. When a user selects the “Attach” selectable object 202, a menu (not shown) can be presented in the view 200, or over the view 200, to facilitate user selection of one or more electronic files to attach to the email. In response to the user selecting one or more electronic files, such electronic file(s) can be attached to the email. “Attach” selectable objects are well known to those skilled in the art. In another arrangement, the user can drag one or more user interface objects representing electronic files over the view 200 to cause such electronic files to be attached to the email, as also known to those skilled in the art.
In addition to conventional recipient fields, such as a “To” field 204, a “Cc” field 206, and a “Bcc” field 208, the view 200 can include a “FYI” field 210. In the “FYI” field 210, the user can identify e-mail recipients who are to receive the email, but not receive the content. E-mail recipients identified in the fields 204-208 can receive the content, however. In illustration, the email recipients identified in the fields 204-208 can receive the email as the email is originally composed by the sender of the email, including the content. E-mail recipients identified in the field 210 can be sent a second email that does not include the content. Further, the second email can include information relating to the first email. Such information can indicate who is to be contacted to receive further information regarding the first email and/or the content sent with the first email.
Further, when a trusted recipient who received the first email chooses to forward the first email to one or more non-trusted recipients, for example by selecting a “Forward” user interface object 212, the second email can be automatically generated and sent to the non-trusted recipients in lieu of the first email. The second email can be generated by the email client of the user who chooses to forward the email, or by the email server.
In one embodiment, at least part of the information provided in the second email can be automatically generated, for example by the email client 102 or the email server 130 depicted in FIG. 1. In illustration, rather than sending the body of the originally composed email, a new email body 214 can be automatically composed for the second email. The automatically composed email body 214 can indicate to the recipients of the second email who those recipients may contact to discuss the subject matter identified in the second email. The automatically composed email body 214 also can indicate to the recipients of the second email at what time they may contact the designated person. As noted, different recipients may be provided different contact times to ensure that the contact person is not inundated with information requests.
The second email can indicate recipients identified in the “To” field 204 and “Cc” field 206, though this need not be the case. Further, the second email also can indicate the recipients identified in the “FYI” field 210, but this also is not required.
FIG. 3 is a flow chart illustrating a method 300 of sending content via email in accordance with an embodiment of the present invention. At step 302, a first email addressed to two groups of recipients can be identified. The first email can comprise content. At step 304, the first email can be communicated to a first group of recipients. The first group of recipients can include recipients that are trusted recipients. At step 306, a second email can be generated. The second email can be different than the first email and not include the content. Further, the second email can comprise information that indicates a contact that a second group of recipients are to contact regarding subject matter associated with the first email.
At decision box 308, a determination can be made as to whether a number of members in a second group of recipients exceeds a threshold value. The second group of recipients can be non-trusted recipients. If so, at step 308 members of the second group of recipients can be classified into a plurality of subgroups. For example, each of the members in the second group of participants can be associated with a respective level of an organization hierarchy, and the each subgroup can include members that are associated with a particular level. At step 310, a time at which contact is to occur can be determined based on the classification of the second group of recipients within the respective subgroups. Such time can be included within the second emails sent to the second group of recipients. More particularly, the second email can be customized for each subgroup to indicate to the members of that subgroup when they should establish contact with the designated entity (e.g., a person designated to be the contact). In one embodiment, the second email can be configured to automatically add a calendar entry corresponding to the time at which the contact is to occur into an electronic calendar of the non-trusted recipient.
Regardless of whether the members of the second group of participants are classified into a plurality of subgroups, at step 312 the second email can be sent to the second group of participants. In one embodiment, the second email can be sent to different subgroups at different times. In illustration, a subgroup comprising recipients who rank high in an organizational hierarchy can first receive the second emails, a subgroup comprising next highest ranking recipients can receive the second emails at a later time, and so on.
FIG. 4 is a flow chart illustrating a method 400 of sending content via email in accordance with another embodiment of the present invention. At step 402, a request from a trusted recipient to forward a first email to a non-trusted recipient can be identified. The first email can comprise content. At step 404, a second email different than the first email, and not comprising the content, can be generated. The second email can comprise information that indicates a contact that the non-trusted recipient is to contact regarding subject matter associated with the first email. The second email further can comprise information that indicates a time at which to the contact is to occur. The contact can be a designated entity, such as a person who is designated to be the contact. At step 406. The second email can be communicated to the non-trusted recipient. In one embodiment, the second email can be configured to automatically add a calendar entry corresponding to the time at which the contact is to occur into an electronic calendar of the non-trusted recipient.
FIG. 5 is a block diagram illustrating a system 500 for sending content via email in accordance with an embodiment of the present invention. The system 500 can include at least one processor 505 coupled to memory elements 510 through a system bus 515. As such, the system 500 can store program code within the memory elements 510. The processor 505 can execute the program code accessed from the memory elements 510 via the system bus 515.
