## Background
RELATED APPLICATION
Under provisions of 35 U.S.C. §119(e), the Applicant claims the benefit of U.S. provisional application Ser. No. 60/212,670, filed Jun. 20, 2000, which is hereby expressly incorporated herein by reference.


TECHNICAL FIELD
The present invention relates to electronic message transmission. More particularly, the present invention, in various specific embodiments, involves methods and systems directed to identifying electronic messages based on a message content identifier or participant code.
BACKGROUND
The United States Postal Service (USPS) is an independent government agency that provides mail delivery and other services to the public. The USPS is widely recognized as a safe and reliable means for sending and receiving physical mail and other items. The USPS also provides electronic mail service. With the advent and steady growth of electronic mail (e-mail) and electronic commerce, e-mail recipients may be constantly bombarded with increasing numbers of electronic messages.
Once an e-mail recipient's address is disclosed, it is possible for the recipient to receive large number of unwanted electronic messages, such as solicitations for all types of e-commerce products. The e-mail recipient's e-mail address may be disclosed by an Internet service provider or by any third party to which the e-mail recipient has sent an electronic message. to decide whether to delete or save the electronic messages once they are received. This tedious process leads to cluttered electronic mailboxes and a resulting loss of time for the e-mail recipient, as the recipient attempts to manage the e-mails within the electronic mailbox. Other existing methods are similarly undesirable.
Thus, there remains a need for efficiently identifying e-mail messages before they are delivered to an e-mail recipient's electronic mailbox, thereby eliminating the clutter of unwanted e-mail messages and the lost of time managing the e-mail messages within the electronic mailbox.
SUMMARY OF THE INVENTION
Consistent with the present invention, an electronic message identification method and system is provided that avoids the problems associated with current systems and methods for identifying and managing electronic messages.
In one aspect, a method consistent with the present invention for sending an electronic file to a customer comprises receiving an approval from the customer indicating acceptable content for electronic files that are sent to the customer; receiving the electronic file from a sender, the electronic file including file content and a message content identifier corresponding to the file content; comparing the message content identifier to the approval from the customer; and delivering the file content to an electronic mailbox of the customer, if the message content identifier is consistent with the approval from the customer indicating acceptable content.
Both the foregoing general description and the following detailed description are exemplary and are intended to provide further explanation of the invention as claimed.

DETAILED DESCRIPTION
Reference will now be made to various embodiments according to this invention, examples of which are shown in the accompanying drawings and will be obvious from the description of the invention. In the drawings, the same reference numbers represent the same or similar elements in the different drawings whenever possible.
System Operation
FIG. 1 is an exemplary embodiment of a message content identifier system (MCIS system) 100 for a mail service. FIG. 1 illustrates a system layout where a mailer sends electronic messages directly to an e-mail system, in which system filtering takes place as a front end function of the e-mail system.
In FIG. 1, an MCIS participating sender or mailer (MPSM) 101 enters MCIS system 100 by registering with MCIS system 100. During the registration process, MPSM 101 is assigned a participant code or standardized content identifier for identification within MCIS system 100. The MCIS participant code, in addition to specifically identifying the industry segment of MPSM 101 and their company, identifies multiple permutations of product type codes or offering codes that are associated with the specific company, so that electronic messages sent by MPSM 101 to MCIS system 100 can be accordingly identified. Once the registration process is complete, these product codes are provided to MPSM 101, with the product type permutations, via some electronic communication, such as an e-mail. The registration process and the MCIS participant code structure and coding process will be described in greater detail below.
Before transmitting the electronic message, MPSM 101 embeds the MCIS participant code into the electronic messages that are generated and transmits the electronic messages through network 102 to MCIS Mailer Interface 104. Network 102 may be the internet or any type of analog or digital communications network. MCIS Mailer Interface 104 communicates with a core application 120 of MCIS system 100. Core application 120 interfaces e-mail system 114 and ICRS system 112 and allows the setup of MPSM 101 on e-mail system 114, using master content ID database 122. Master content ID database 122 contains the codes that core application 120 interrogates and stores for allocating the participant code to each MPSM 101, during the registration process.
To access the e-mail message transmitted by MPSM 101, a customer 106 must register with an e-mail system 114 of MCIS system 100. Using laptop 108, customer 106, through network 110, logs into an Internet customer registration system (ICRS system) 112. Network 110 may be the internet or any type of digital or analog communications network. With ICRS system 112, customer 106 registers and sets up the e-mail account by making selections for message filtering options. For additional information on ICRS system 112, please refer to U.S. application Ser. No. 09/809,328 filed on Mar. 16, 2001.
In this embodiment of the present invention, the filtering selection could occur when a customer registers or it could be an adjunct feature once the actual mailbox is established. When implemented as an adjunct feature, the filters may be set up within the mailbox itself rather than during the process of obtaining the mailbox.
Once MPSM 101 is registered as a participating mailer and customer 106 has signed up with MCIS system 100, then when MPSM 101 sends e-mail directly to the front end of e-mail system 114 via network 102 and MCIS filter 116, MCIS filter 116 checks the MCIS participant code against the preferences that the specific customer has indicated and executes appropriate routing.
At this point, MCIS filter 116 may either route the electronic message and deliver it to the customer's mailbox within e-mail system 114 or reject the electronic message and notify MPSM 101 that the message has been rejected. As a third option, MCIS filter 116 may deliver the electronic message into a generic pool instead of an identified specific MCIS filtered mail folder within the customer's mailbox. Customer 106 would then know that this electronic message did not meet the filtering criteria to be delivered to the mailbox, but it was sorted as it entered the box and was rejected. In any event, feedback is provided to MPMS 101 as notification of the outcome of the attempt, either successful or unsuccessful. Customer 106 then may enter his e-mail box 118 within e-mail system 114, using laptop 108 and network 110, and view the MCIS filtered electronic messages, non-filtered electronic messages, or another functional segments of the E-mail box 118.
FIG. 1 as previously described, focuses on the system layout and flow where the mailer is sending electronic messages directly or attempting to send electronic messages directly to customer 106. FIG. 2 is an alternative embodiment where MPSM 101 may submit electronic files containing physical addresses, and possibly electronic addresses, and message content that contains MCIS participant coding. The service provided by this alternative embodiment may be implemented as a separate intermediate service.
In this alternative embodiment, a physical address mailing list file 202 is uploaded, using a program, from MPMS 101 to an e-address processor 206. E-address processor 206 will be described in greater detail below. E-address processor 206 queries an ICRS customer database 208. As a result, ICRS customer database 208 outputs the customer's e-address and filtering preferences. ICRS customer database 208 contains the data supplied when customer 106 registered and set up the virtual e-addressing account with the mail service and initially recorded the filtering preferences.
The query executed by E-address processor 206 may be implemented by several different means. For example, the query may be based on the physical address, codes that are associated with the physical address, the customer's name, or account numbers associated with the customer. The query uses one or more of the above mentioned components to translate the physical address mailing list file 202 to an electronic address.
Furthermore, in this alternative embodiment, message content with MCIS coding 204 is also uploaded, using a program, to e-addressing processor 206, where the e-addressing information, message content and the MCIS coding are combined and the electronic message is created. The electronic message with the embedded coding is then sent to the MCIS filter 116 of FIG. 2, where the customer preferences are identified. The electronic message is subsequently sent into an e-mail message routing system 210 for delivery into electronic mailbox repository 212. Then, return statistics are sent to MPSM 101 via an e-address status reporting module 214.
Before describing, in FIG. 3, the internal details of e-addressing processor 206, it is important to emphasize that the filtering executed by MCIS filter 116 may be implemented as part of the ICRS database query. Because the customer preferences may be stored on ICRS customer database 208, the filtering may take place as part of the querying process. The filtering process may also be implemented within e-address processor 206. The filtering process may be implemented in either fashion, that is, as part of the query of ICRS customer database 208, or by referencing back to the mail merge processor within e-address processor 206. The mail merge processor provides the function of creating the electronic message and will be discussed in the description of the internals of e-addressing processor 206.
In the case where the message filtering is performed during the querying of ICRS customer database 208, the e-mail message does not have to run through the entire system before the filtering may take place. Processing may occur at the ICRS customer database 208 to identify those customers that in fact will accept the message content. Using this approach, message routing/handling decisions may be made upstream versus downstream in the process, and the message may be delivered directly to the e-mail message routing system 210 for delivery into electronic mailbox repository 212.
FIG. 3 is a block diagram of the internal processes within the e-addressing processor 206. The numbers used in FIG. 3 correspond to the numbering system that is used in FIG. 2. FIG. 3 illustrates that physical address mailing list file 202 may be uploaded to an address matching system 302. In address matching system 302, the physical addresses are parsed and match codes are constructed for interrogating a match directory, within the address matching system, to obtain a match directory address associated with the input physical address. If a match is obtained, then the zip plus 4 code and all the other associated information contained within the address matching system for the associated physical address is fed into a key generation and e-addressing query function 304, which in turn feeds a query to ICRS customer database 208.
As a result of the database query, an output is provided from the ICRS customer database 208 to e-addressing processor 206. The output is an electronic address mailing list file 306, which is fed into a mail merge processor 308. Mail merge processor 308 receives message content with MCIS coding 204 and creates the electronic message. The resulting electronic message is then transferred to MCIS filter 116, where the customer preferences are identified. The electronic message is subsequently sent into e-mail message routing system 210 for delivery into electronic mailbox repository 212.
The intelligence from within mail merge processor 308 may be returned to the ICRS customer database 208 and messages may be tagged with appropriate routing information for historical information tracking.
MCIS Participating Sender or Mailer (MPSM) Processing
FIG. 4 illustrates the process for applying the participant coding or standard content identifier to the message content. MPSM 101 inputs a message content 402 to a content coding program 404, where message content 402 is coded with a participant coding or standard content identifier 406. The participant code or standard content identifier may be inserted into the header section of an electronic message. Then, the electronic message is sent to E-mail system 114 via MCIS filter 116.
Next, FIG. 5 illustrates that the electronic message, including content 402, participant or standardized content identifier 406, and a recipient address 502, is received and submitted to filters 504. The recipient address 502 may be the customer's electronic mail box address. Filters 504, in turn, identify the customer's preferences, which were setup during the registration process, and apply the preferences to participant or standardized content identifier 406. Then, according to the identified preferences that are consistent with the participant or standardized content identifier 406, the electronic messages are delivered to the appropriate folders. For example, bills are delivered to a folder 510, secure mail may be delivered to a folder 512, advertisements may be delivered to a folder 514, and e-mail may be delivered to a folder 516. For additional security, security features 506 and 508 are applied before bills and secured mail are delivered to their appropriate folders. The security features (506 and 508) may be a type of electronic security message, protocol, or handshake used to distinguish between authorized and unauthorized system users. For example, the security features (506 and 508) may be a fire wall.
Participant Code or Standard Content Identifier
MCIS system 100 provides a standardized method for electronic messages and their content to be identified and subsequently filtered (accepted or rejected), based upon on the MCIS participant code or standardized content identifier 406. As described above, MCIS participating sender or mailer (MPSM) 101 is provided with content coding program 404 (FIG. 4) to provide associated product type identifiers that may be incorporated into MCIS system 100.
Once established as an MCIS system 100 participant, MPSM 101 provides this participant code or standardized content identifier 406 as part of all submitted messages for potential electronic delivery by the mail service or by other private commercial electronic message services licensed by the mail service to provide MCIS system messages to their customers.
The participant code or standardized content identifier may be implemented with the following MCIS code format:
NNNNNNMAAAANNNNNNC
N=Numeric (0-9)
A=Alpha (A-Z)
C=Modulus 10 check digit
The MCIS code format is 18 characters in length plus a check digit and is divided into three segments:
I. The first six characters (NNNNNN) identify the industry segment and is based upon the North America Industry Classification System (NAICS);
II. The next six characters of the code (AAAAAA) specifically identify a company within the industry segment and is based on the Address Change Service (ACS) participant code, which is describe in the publication of Appendix A (United States Postal Service, Address Change Service, Publication 8 (July 1998));
III. The last six characters (NNNNNN) are used to identify a specific product type or offering by a company;
IV. The last digit (C) is used to ensure the integrity or accuracy of the preceding 18 characters;
For example, the MCIS participant code or standardized content identifier may be 721191BRXJKT5011521. The component parts are:
I. 721191—the NAICS code that identifies the industry segment for Bed-and-Breakfast Inns;
II. BRXJKT—identifies a specific Bed-and-Breakfast Inn (e.g., XYZ Bed-and-Breakfast in Anytown, USA);
III. 501152—identifies the contents of the messages as being an advertisement for discount offers for rooms booked 60 days in advance for stays during the month of July;
IV. 1—identifies the check digit that ensures the integrity or accuracy of the preceding 18 characters.
Method of Operation
FIG. 6 is a flow diagram of a method 600 used by MPSM 101 to send electronic messages to a recipient's mailbox. To initiate the transfer of information, method 600 starts, the sender applies a standard coding to the message content to be delivered to the recipient, and the recipient specifies the type of content to be received and/or identifies the approved senders. (Stage 602-606).
Once the mail service receives the content with the standard coding from MPSM 101, the mail service reads the standard coding and compares the standard code to the recipient's preferences (Stage 608). The recipient's preferences specify the content that the recipient wishes to receive and/or identifies the approved senders. (Stage 610). If the standard code from MPSM 101 is inconsistent with the recipient's preferences, the mail service does not route the message content to the recipient's mailbox, and may notify MPSM 101 of non-delivery. (Stage 614). Then, the method ends. (Stage 620).
If the standard code from MPSM 101 is consistent with the recipients specification, the mail service routes the content to the appropriate folder in the recipient's mailbox, and may notify the sender of the delivery. (Stage 616 and 618). Then, the method ends. (Stage 620).
In view of the foregoing, it will be appreciated that the present invention provides a system and method directed to identifying electronic messages based on a message content identifier or participant code. Still, it should be understood that the foregoing relates only to the exemplary embodiments of the present invention, and that numerous changes may be made thereto without departing from the spirit and scope of the invention as defined by the following claims.
