## Background
BACKGROUND OF THE INVENTION
1. Field of Invention
This invention generally relates to systems and methods for uniformly identifying digital files.
2. Description of Related Art
High value information is frequently inaccessible to users of wireless-enabled and/or web-enabled personal digital assistants, web-enabled cell phones and the like, which are generally referred to herein as mobile information devices (MID), because this information is embedded as an e-mail attachment inaccessible to software installed on the mobile information device. Mobile information devices include handheld devices that combine computer applications with telephony and/or remote networking features. A mobile information device may be equipped with a hypertext-markup-language (HTML) or wireless access protocol (WAP) browser and/or an e-mail reader.
E-mail attachments may be in any number of file formats, such as, for example, spreadsheet, word processing, or high resolution graphical files. Software applications which can interact with the data format of the attachment file are frequently not installed on the mobile information device. Instead, these applications are installed only on a remote mobile document access server, while the attachments are stored in some repository that is accessible to the server. Therefore, the user of the mobile information device cannot easily access the information embedded in these attachments. The access server allows a remote user to fax, print, and view information stored in corporate repositories. In response to a command issued at the mobile information device, the access server can prepare the attachment for printing or faxing, and may additionally dispatch the prepared attachment to a remote location.
SUMMARY OF THE INVENTION
The document creator applications, e-mail software, communication software, and mobile information device-resident browsers come from various suppliers. Existing methods for accessing the attachments are ad-hoc, and do not work for many combinations of these components.
As outlined above, conventional e-mail attachment identification techniques are typically proprietary and dissimilar. Moreover, conventional methods for accessing e-mail attachments do not work for many software component combinations.
This invention provides systems and methods for uniformly identifying e-mail attachments.
This invention separately provides systems and methods for uniformly identifying e-mail attachments from mobile information devices.
In various exemplary embodiments according to this invention, an electronic file is identified by a record including a unique identifier field and/or a user-friendly textual field. The unique identifier field may be any alphanumeric string that can uniquely identify the document. In various exemplary embodiments, the unique identifier is a uniform resource locator. In various other exemplary embodiments, the unique identifier is an integer. This alphanumeric string may be generated using any known technique. For example, a unique integer identifier may be generated by adding a value incrementor to a previous unique identifier.
In various exemplary embodiments of the systems and methods according to this invention, the user-friendly text is the name of the electronic file. In various other exemplary embodiments, the user-friendly text is a title or text string obtained or extracted from the document, where the title or text string is different from the name of the document.
In various exemplary embodiments of the systems and methods according to this invention, the uniform identifier record is appended to an electronic file to which the file identified by the uniform identifier record is associated. The electronic file may be e-mail. The associated file may be an e-mail attachment.
These and other features and advantages of this invention are described in or apparent from the following detailed description of the systems and methods according to this invention.

DETAILED DESCRIPTION OF EXEMPLARY EMBODIMENTS
FIG. 1 illustrates one exemplary embodiment of a uniform identifier record 100 according to this invention. As shown in FIG. 1, the uniform identifier record 100 comprises one or both of a unique identifier field 110 and a user-friendly text field 120. The uniform identifier record 100 is generated by a software application or component located at a mobile document access server. The unique identifier (UID) located in the unique identifier field 110 may be a uniform resource locator (URL) specifying the location of the attachment file on the Internet or some other distributed network. Alternately, the unique identifier located in the unique identifier field 110 may be numeric or alphanumeric in nature. Thus, the unique identifier located in the unique identifier field 110 may be a globally unique identifier (GUID). The unique identifier located in the unique identifier field 110 may also be an integer value where each new unique identifier is created by adding a constant to a predecessor unique identifier value.
The user-friendly text field 120 is able to contain any textual information usable to appropriately identify the attachment file. Thus, the text string in the user-friendly text field 120 can be the name of the attachment file. Alternatively, the text string in the user-friendly text field 120 can be the title or any other text string of the document, where the title or other text string can be obtained or extracted from the attachment file and is different from the name of the document.
In various exemplary embodiments, the uniform identifier record 100 is a character string. The unique identifier field 110 and the user-friendly text field 120 portions of the uniform identifier record 100 are delimited by any known or later-developed text delimiter, such as, for example, commas, tabs or any other appropriate non-printing character combinations.
In various exemplary embodiments, the uniform identifier record 100 is appended to the message body of the e-mail file associated with the identified attachment. FIG. 2 illustrates one exemplary embodiment of an e-mail file 200 modified in accordance with the invention to include one exemplary embodiment of a uniform identifier record. As shown in FIG. 2, the e-mail file 200 includes the uniform identifier record 100 appended to the original e-mail body 210. More than one uniform identifier record 100 may be appended to the e-mail body 210 when the e-mail file 200 contains more than one attachment.
FIG. 3 is a flowchart outlining one exemplary embodiment of a method for processing an e-mail attachment at an access server under the direction of a remote user. As shown in FIG. 3, operation of the method begins in step S1000, and continues to step S1100, where an e-mail file associated with an attachment file and addressed to a remote user, who is accessing the e-mail using a mobile information device, is modified to include a uniform identifier record according to this invention and is sent to the mobile information device. Then, in step S1200, the user-friendly attachment identifier and an action to be performed on the attachment are selected. The selected action may be faxing, printing, and/or any other appropriate known document processing task. Next, in step S1300, the attachment identifier and an action identifier identifying the selected action are transmitted to the server. Then, in step S1400, the server retrieves the attachment identified by the attachment identifier and executes the action identified by the action identifier against the attachment. Operation then continues to step S1500, where operation of the method ends.
FIG. 4 is a flowchart outlining in greater detail one exemplary embodiment of a method for generating the uniform identifier and transmitting the modified e-mail file to the mobile information device of step S1100. As shown in FIG. 4, operation of the method begins in step S1100, and continues to step S1110, where an e-mail file is received at an access server, or at some other repository on a network accessible to an access server. The e-mail is addressed to a remote user. Then, in step S1120, the e-mail is inspected to determine whether an associated file is attached to the email. Next, in step S1130, a determination is made as to whether the received email file is associated with an attachment file. If not, operation jumps to step S1170. Otherwise operation continues to step S1140.
In step S1140, a unique identifier is generated for the attachment file. Next, in step S1160, a user-friendly description is generated for the attachment file. Then, in step S1170, the unique identifier and user-friendly description are inserted as a uniform identifier record into the message body of the e-mail file. Operation then continues to step S1170.
In step S1170, the e-mail file is sent to the mobile information device being used by the remote user to access the e-mail. Then, in step S1180, operation of the method returns to step S1200. It should be appreciated that, in various exemplary embodiments, the user-friendly text field 120 may not be appended to the email body since its purpose is merely to aid the human user of the mobile information device in distinguishing one attachment from another. In particular, when an email message has no more than one attachment, a user-friendly text field may be deemed unnecessary, and therefore omitted. In this case, step S1150 is skipped or omitted. Then, in step S1160, only the generated one of the unique identifier field 110 or the user-friendly text 120 is inserted into the email.
It should be appreciated that, in various exemplary embodiments of the invention, the user-friendly description may be a unique identifier for the attachment file. In these exemplary embodiments, the user-friendly description is a unique identifier at least in the context of the mobile document access server.
FIG. 5 is a flowchart outlining in greater detail one exemplary embodiment of the method for processing the uniform attachment identifier at a mobile information device of step S1200. As shown in FIG. 5, operation of the method begins in step S1200, and continues to step S1210, where a modified e-mail file is received at the mobile information device. Next, in step S1220, the user-friendly description of the attachment is displayed in a manner associating the attachment file with the received e-mail. The user-friendly description may be displayed iconically, in tabular format, or as a description embedded in and/or following the main e-mail file body. Operation progresses from step S1220 to step S1230, and remains in step S1230 until the user indicates a selection. Once a selection is indicated, operation continues to step S1240.
In step S1240, the current selection is retrieved. Next, in step S1250, a determination is made whether the selection contains or is associated with a valid unique identifier. If not, operation returns to step S1230. Otherwise, operation continues to step S1260.
In step S1260, an action identifier associated with the selected action is retrieved. The action identifier may be a character string similar or identical to the menu selection of the action selected. Alternately, the action identifier may be a numeric identifier associated with the action. Then, in step S1270, operation of the method returns to step S1300.
The unique identifier determined in step S1250 may be stored in a database local to the mobile information device. In various exemplary embodiments, the unique identifier is removed or copied from the e-mail file before the attachment information is displayed. Alternately, in various other exemplary embodiments, the unique identifier may be retrieved from the e-mail file itself after the attachment is selected. In these exemplary embodiments, the unique identifier is not displayed with the user-friendly text. In still other exemplary embodiments, the unique identifier is user-friendly text.
The action determined in step S1260 may be any action that may be appropriately invoked against the selected file. For example, the file can be faxed to any location. Alternatively, the file can be printed. Moreover, the file can be e-mailed to another user. In most cases, this will involve gathering further information from the user, i.e., having the user supply and/or identify further information. For example, to fax the attachment, the user will need to supply the phone number of a receiving fax machine. In various exemplary embodiments, the information is gathered when the user indicates that an action is to be performed on the attachment. In various exemplary embodiments, the further information is gathered, for example, using a pop-up dialog box or other user-interface widget or mechanism appropriate to the mobile information device involved.
FIG. 6 is a flowchart outlining in greater detail one exemplary embodiment of the method for processing at an access server an attachment file identified by a uniform identifier of step S1400. As shown in FIG. 6, operation of the method begins in step S1400, and continues to step S1410, where the unique identifier and an associated action identifier are received at an access server. Then, in step S1420, the attachment file identified by the unique identifier, (or alternatively or additionally by the user-friendly text string) is retrieved. Next, in step S1440, the attachment file is processed according to the action identified by the action identifier. Thus, for example, if the action is to fax the document, a software fax application is executed from the access server, the attachment file is instantiated, and then the identified document is faxed by the application. Then, in step S1450, the operation of the method returns to step S1500.
