The email delivery apparatus 200 may determine the type of resource to be extracted from the email sent from the originating terminal, or convert the email into an image. It is used to determine whether or not. The email viewing method may include three types of methods, for example, a 'text' method, a 'text & image' method, and an 'image' method. The 'text' method extracts only text from an email containing various multimedia resources, and the 'text & image' method extracts only text and images from an email. Lastly, the 'image' method refers to converting an email in HTML format including various resources as well as tables and images into images and adjusting them to the resolution of the mobile terminal 400. The e-mail viewing method for the mobile terminal 400 may be basically set at the time of production of the mobile terminal 400, and may be changed later by a user of the mobile terminal 400.

The email delivery device 200 may provide an email delivery service to the mobile terminal 400 subscribed in advance. Here, the e-mail delivery service refers to extracting a specific resource from the e-mail sent from the originating terminal or converting the e-mail into an image suitable for the receiving terminal according to the e-mail viewing method set for the receiving terminal, and then providing it to the receiving terminal. Say service.

For this processing, the e-mail delivery device 200 may acquire information of the receiving terminal from the storage device 100, convert the e-mail into an image, or block e-mail based on the obtained information. . Here, the e-mail delivery device 200 will be described in more detail with reference to FIG. 2.

2 is a view schematically showing the configuration of the email delivery device 200 according to an embodiment of the present invention. As shown in FIG. 2, the email delivery device 200 includes an external device interface unit 240, a collection unit 230, a processing unit 220, a terminal interface unit 210, and a storage unit 250. can do.

The external device interface unit 240 may be responsible for transmitting and receiving data or control signals between the email delivery device 200 and the external device. Here, the external device may be an originating terminal that has sent an email or an external mail server that temporarily stores an email sent from the originating terminal.

The collection unit 230 may collect information necessary for processing an email received from an external device. The information may be collected from the storage device 100. Examples of the collected information may include hardware information of a receiving terminal, software information of a receiving terminal, information on whether a receiving terminal subscribes to an email delivery service, and a receiving terminal. For example, information on how email is set up.

The processor 220 may process an email received from an external device based on the information collected by the information collector 230. Looking at the operation of the processor 220 in more detail, the processor 220 may first determine whether the receiving terminal is a mobile terminal 400 subscribed to the email delivery service. As a result of the determination, if the receiving terminal is not subscribed to the email delivery service, the processor 220 may provide the email to the receiving terminal as it is. If the receiving terminal is subscribed to the email delivery service, the processor 220 may check whether abnormal data is included in the email. In detail, the processor 220 may determine whether an abnormal key, virus, or malicious script is included in the email.

As a result of checking whether there is abnormal data, if an abnormal key, virus, malicious script, etc. are included in the e-mail, the processor 220 checks whether they can remove them. If the abnormal data can be deleted, the processor 220 may delete them, and if it is impossible to delete the processor 220, the processor 220 may block an e-mail containing the abnormal data. Then, the blocking result may be provided to the receiving terminal.

After deleting the abnormal data from the e-mail, the processor 220 may check whether the e-mail includes a resource that cannot be expressed in the receiving terminal. To this end, the processor 220 may refer to software information of the receiving terminal.

As a result of the check, if the resource that cannot be expressed in the receiving terminal is not included in the e-mail, that is, only the resources that can be expressed in the receiving terminal are included in the e-mail, the processor 220 is based on the e-mail viewing method set for the receiving terminal. E-mail can be processed. For example, if the email viewing method in the receiving terminal is set to the 'text' method, the processor 220 may extract only text from the email. If the email viewing method in the receiving terminal is set to the 'text & image' method, the processor 220 may extract the text and the image from the email in order. In this case, the extracted images may have various sizes, and the processor 220 may adjust images of various sizes appropriately for the receiving terminal.

On the other hand, if it is confirmed that the e-mail includes a resource that cannot be expressed in the receiving terminal, the processing unit 220 refers to the hardware information of the receiving terminal, regardless of the e-mail viewing method set for the receiving terminal, to send the e-mail. You can convert it to an image.

Specifically, the processor 220 may change the layout of the email in consideration of the size and / or resolution of the LCD provided in the receiving terminal, and then convert the email with the changed layout into an image.

As described above, the processing unit 220 may process the email received from the external device based on the information collected by the information collecting unit 230, or after the transmission of the processed email is completed, the request of the receiving terminal. Therefore, the email received from the external device can be further processed. For example, when the user of the receiving terminal changes the e-mail viewing method while checking the e-mail, the processor 220 may process the e-mail received from the external device according to the changed e-mail viewing method. Here, reference will be made to FIG. 3 to help understand the operation of the processor 220.

When the e-mail viewing method requested by the receiving terminal is the 'text & image' method, it can be seen that only text and images are extracted purely from various resources included in the e-mail. Then, it can be seen that the extracted text and images are arranged in the order contained in the email before processing. When the email viewing method requested by the receiving terminal is the 'image' method, it can be seen that an email including various resources is converted into an image 310. At this time, the image 310 output from the processing unit 220, as compared to the email 300 input to the processing unit 220, it can be seen that the overall size is reduced to match the resolution of the receiving terminal. In addition, the text 311 and the image 312 included in the image 310 output from the processor 220 are as fine as the text 301 and the image 302 included in the e-mail 300 before processing. Instead of expressing otherwise, it can be seen that the location of text 311 and image 312 is similar to the location of text 301 and image 302 included in email 300 before processing. As such, not only the layout of the e-mail is changed in consideration of the size of the LCD provided in the receiving terminal, but also the corresponding e-mail is converted into an image optimized for the resolution of the LCD provided in the receiving terminal, so that the user of the receiving terminal is an e-mail sender. In other words, you can see at a glance what the sender is trying to convey via email.

Referring back to FIG. 2, the terminal interface unit 210 may be responsible for transmitting and receiving data or control signals between the email delivery device 200 and the mobile terminal 400. For example, the terminal interface unit 210 may transmit an email or an image processed by the processing unit 220 to the receiving terminal. In addition, when the user of the receiving terminal changes the e-mail viewing scheme, the terminal interface unit 210 may receive a control signal related thereto from the receiving terminal.
