Abstract:
A sever receives data from a sender to be dispatched to a recipient. Before dispatching the data to the recipient the server sends a message to the sender&#39;s email address requesting a response which will confirm the sender&#39;s authorship of the data. Upon receiving the confirmation about sender&#39;s authorship of the data, the server transmits the data together with an identification of the sender to the recipient.

       [0001]    This application claims the benefit of priority from Provisional Application Nos. 61/538,669 and 61/538,772 filed Sep. 23, 2011, each of which is incorporated by reference in its entirety. 
     
    
     FIELD OF DISCLOSURE 
       [0002]    The present disclosure relates to the field of transmission of messages, particularly email messages from sender(s) to receiver(s). More particularly this disclosure relates to authenticating the sender of the data prior to transmitting the data to intended recipient(s). This disclosure also relates to a system and method whereby the recipient verifies the origin of a message and authenticity of the sender before receiving a message from the sender. 
       BACKGROUND 
       [0003]    In recent years e-mail has transformed into an indispensable business tool. Email once used as a mode of personal communication has extended its reach to a plurality of diversified segments including business administration, human resources management and marketing management, to name a few. Existing email functions also provide some sort of proof of delivery of the mail to the intended recipient. For example, in certain email systems senders are provided with the option of obtaining notifications about the status of their messages. i.e., when a message is delivered to the intended recipient, the sender gets a notification stating that the message has been delivered to the intended recipient. Alternatively, if the sender requests for delivery notification, the email system might provide a delivery notification to the sender. Even though the aforementioned feature (delivery reports corresponding to emails) is not mandatory, some of the email systems provide this facility. Since accountability for transmitted email is non-existent or minimal, senders are wary of the fact that their confidential emails may be delivered to non-intended recipients, and recipients are wary of the fact that they might receive emails from unidentified/unknown sources. 
         [0004]    Therefore there is a need for an email system/method that can scrutinize the identity of at least the sender before sending the email generated by the sender. 
         [0005]    To resolve the accountability issue, some email service providers came up with the concept of third party notifications wherein a third party would act as an intermediary between the sender and receiver. The third party would monitor the status of emails transmitted from a sender and intended for a recipient/receiver. The third party was supposed to accordingly update on the status of email to the sender. However, one of the primary disadvantages of the third party notification concept is that the email and the corresponding attachments were to be loaded on to the third party website. Such a necessity resulted in a communication method that was slow and cumbersome. Moreover, the third party systems did not have any mechanism to authenticate the sender of the message and verify that the sender is the owner of the email being transmitted. Therefore, there was felt a need for a system/method that overcame the aforementioned disadvantages. The present invention satisfies these, and other needs. 
       SUMMARY OF THE INVENTION

     DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS 
       [0026]    The system and method of the present invention is explained with reference to email messages and network architecture necessary for the implementation of email system. It is to be understood that such an explanation is only for the purpose of illustration. The system and method envisaged by the present disclosure can be applied to other protocols and other message types without departing from the scope of the disclosure. 
         [0027]    It will be understood by those skilled in the art of message and data transmission over networks that the various embodiments of the present invention may be implemented using servers, processors, data storage and various software programs, such as email systems, network protocols and the like as are known by those skilled in the art. For example, a server such as is described below will typically include one or more processors that are controlled by software programs to carry out the various steps described. Such a server will include communication ports for communication of data to and from the server. The communication port may also allow for information to be stored by the processor of server onto a data storage device, which may be any data storage or memory device known in the art. The processor may also communicate over a network, which may be wired or wireless, so as to implement the various embodiments of the present invention. 
         [0028]    Referring to  FIG. 1 , there is shown a server  10 . The server primarily acts as the outgoing mail transfer agent (MTA) for a message sender&#39;s mail user agent (MUA)  12 . The MUA  12  is utilized by a sender to create an email message (electronic data). Possible MUAs&#39; include client side email programs, server-side email programs, web based email programs and HTML pages submitted through websites/web services. The intended recipient/addressee/receiver of the message is denoted as the recipient  14 . In accordance with this disclosure, the server  10  receives a message that is to be transmitted to a recipient. On receiving a message to be transmitted, the sever locally stores the message in a repository  16  and subsequently creates a plurality of fields corresponding to the message, in the repository  16 . The fields created by the server include but are not restricted to the time at which the message was received, name of the attachments of the message, and the number of addresses of the message. 
         [0029]    For every destination mentioned in the received message, the server  10  records at least the name of the destination, internet address of the destination, and the time at which the message was delivered to the destination&#39;s mail server. These records are subsequently stored in the repository  16 . 
         [0030]    Subsequent to receiving a message to be transmitted to a recipient, the MTA of the server  10  transmits another message, also referred to as a ‘notification’ to the corresponding sender asking for sender&#39;s confirmation of the ownership of the message. Typically the notification is sent in the form of an email message to the corresponding sender from the server  10 , in order to confirm the ownership of the message that is needed to be transmitted from the server to an intended recipient. The server  10  modifies certain headers of the notification message in order to make sure that the sender&#39;s reply to the notification is sent to a place from where the server  10  can access and process the replays, and also to ensure that an appropriate reply is elicited from the sender. For example, if the name of the sender is ‘john smith’, and his web address is ‘johnsmith@adomain.com’, the server sends the notification to ‘johnsmith@adomain.com’. The address of john smith is included in the ‘TO’ column of the notification message. Further, the server  10  automatically modifies some of the headers of the notification message to ensure that the reply from john smith is always accessible to the server  10  for processing. The notification message is sent to john smith&#39;s MUA (Mail User Agent) which is in turn requested to send the reply from john smith to an address specified by and accessible to the server  10  for processing. 
         [0031]    Subsequently, the creator of the message (sender) replies to the notification message sent by the server, and confirms his/her ownership of the message that needs to be transmitted to an intended recipient. The ownership is confirmed by the sender typically via an email. Subsequent to receiving the confirmation of the ownership of the sender, the server  10  transmits the message received from the sender to the intended recipient. Along with the message, the proof of identity and proof of ownership of the sender is also embedded by the server  10 . The proof of identity and proof of ownership of the sender may be embedded into the message, or may be included as a separate attachment to the message. Bothe message with the embedded content, or the message with an attachment containing the identity of the sender and proof ownership by be encrypted for secure transmission over a network, such as the Internet. 
         [0032]    When a message intended for a particular recipient is received by the server  10 , the server  10  stores a local copy of the message in the repository  16 . The server may also optionally modify the received message. For example, after the end of the message body, a web link or a web page address can be inserted by the server. The intended recipient may click on or otherwise activate the link to confirm the receipt of the message. 
         [0033]    Further, the message may also be modified by the server in such a way that the message enables the recipient to go to a website by clicking on a hyperlink available as a part of the message, and subsequently compose a new message or reply to the received message, thereby confirming his/her identity. 
         [0034]    In one embodiment, for every outgoing message, i.e., for every message sent from server  10  to the intended recipient, the server  10  creates a unique code/unique identification number corresponding to the message. The unique code can be a timestamp indicating the time at which the message was sent from the server  10 . The unique code may also be stored in the repository  16  for future reference. Optionally, the unique code/identification number can also be embedded in the message that is sent to the recipient from the server  10 . For example, the “FROM” field of the message can be augmented to contain the unique code of the message along with the address of the recipient of the message. Optionally, the unique code/identification number can also be included in the message when the message is received from the sender at the server. Optionally, the unique code/identification number can also be embedded in a web link or a web address that is sent as a part of the notification message, from server  10  to the sender. 
         [0035]    The notification message transmitted from the server  10  to the sender may also prompt the sender to provide indications of his/her identity and also indication of the ownership of the message transmitted from the sender to the server  10 . The sender could indicate his identity and ownership of the transmitted message by drawing/creating a digital signature on a user interface made available to the sender. The digital signature created by the sender is stored in the repository for further process and verification. Optionally, subsequent to transmitting the email message the intended recipient of the message can also be prompted to prove his/her identity. The recipient can also be prompted to draw a digital signature on a web interface made available to the recipient. Subsequently, the digital signature of the recipient is compared with signatures previously stored in the repository  16 , and only on finding a match, the recipient is provided access to the email message sent by the server  10 . 
         [0036]    In another embodiment, the timestamp denoting the date and time at which the email message is transmitted from the server to the recipient is created and stored for further reference. Further, the date and time at which the sender provides indications of his identity and ownership, is also converted into a timestamp and is used as a confirmation of authorship/ownership of the user. This timestamp is also attached to the email message being sent from the server to the recipient, in order to assure the recipient of authenticity of the email message. 
         [0037]    The indications of identity and ownership of the transmitted email message are embedded with the email message being transmitted to the recipient. This procedure is followed in order to assure the recipient that the message is from an authentic and genuine source. In an alternate embodiment of the present invention, the recipient of the message can also specify the indications of identity and ownership, required to be provided by the sender. In such cases the email message being sent to the recipient is augmented with the sender&#39;s indication of identity and ownership of the transmitted message. 
         [0038]    In one embodiment of the present invention, the email message is transmitted in an encrypted format from the server  10  to the recipient. Any of the well-known public cryptography techniques can be utilized to encrypt the message sent from the server  10  to the recipient. The receiver, using any of the well-known techniques, decrypts the encrypted message. 
         [0039]    Referring to  FIG. 2 , there is shown a flowchart corresponding to an embodiment of a method for authenticating a sender of electronic data to a recipient. 
         [0040]    In box  100 , electronic data including at least email address of the sender, is received from the sender at a server remote from the sender. In box  102 , a message is transmitted from the server to the sender&#39;s email address, wherein the message requests confirmation of the sender&#39;s ownership of the transmitted electronic data. 
         [0041]    A confirmation of the sender&#39;s ownership of the transmitted electronic data is received at the sender in box  104 , wherein the confirmation is in response to the message sent from the server to the sender&#39;s email address  104 . A copy of the electronic data generated by the sender, and a confirmation of the identity of the sender of the electronic data is transmitted from the server to the recipient in box  106 . 
         [0042]    In another embodiment, the method further includes the step of transmitting the electronic data from the sender to the server, in the form of an email message. In still another embodiment, the method further includes the step of transmitting the electronic data received from the sender to an internet web server for the purpose of delivery to the recipient.
