Abstract

PURPOSE:To prevent a received mail from being applied with reception post- processing without permission by providing a means setting it to a mail header as to whether or not the reception post-processing is permitted to a recipient and a means disabling the reception post-processing not permitted for the above to a processor. CONSTITUTION:The processor 200 is provided with a function such as forming a mail, transmission/reception or storage via a terminal device to a system user, a function controlling plural reception post-processings performed by the recipient to the received mail, a function setting it to a mail header of a mail transmitted by a sender as to whether or not the reception post-processing is permitted to the recipient and a function checking the received mail header and disabling the received post-processing not permitted. Whether or not the received post-processing is permitted to the receipient is set to mail headers 380-382 of the mail 300. The number of the received post-processing to be inhibited is set to the 380 and its contents is set to the 381 and succeeding headers.

Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field of the Invention] The present invention relates to an electronic mail system that can prevent a recipient from performing processing on received mail that the sender has not authorized.

[Techniques of Invention - Background and Intervals 44 (, points)] With the development of OA (office automation), e-mail systems for the purpose of sending texts, notes, data, etc. have become popular. This e-mail system sends sending information entered from a terminal etc. as an e-mail to a desired destination via an exchange network or an ID network. Display the content on your device, then print it, save it to the recipient's local file, or edit it and forward it to someone else. The recipient may want to control the processing after reception due to reasons such as I'f'2 confidentiality.

Even if the content of the email is displayed, it is fine, but if it is printed, it will be 1-4%.

In the conventional ``peko mail system'', 1 (tl) In such a case, either include a statement in the email saying, ``I do not want you to do anything other than display it,'' or request it in advance using a communication method other than the e-mail system. There was no other way.

These methods are troublesome and complicated, and there is also a problem in that there is no guarantee that the recipient can be prohibited from processing as desired by the sender.

[Purpose of the invention]

The present invention was created in consideration of these circumstances, and its purpose is to prevent the recipient from performing any processing on received mail that the sender has not previously authorized. Its purpose is to provide an e-mail system.

[Summary of the invention]

The present invention provides an e-mail system in which a processing device includes:
Recipients can view, print, and view received emails.
A means for the sender to set in the email header whether or not the recipient is permitted to perform processes such as saving and sending 5 times (referred to as post-reception processing), and a method for setting the email header of the received email A means for preventing post-reception processing is provided so that the recipient cannot perform post-reception processing on the received e-mail that is not permitted by the sender when receiving the e-mail.

〔Effect of the invention〕

Thus, according to the present invention, it is possible to reliably and easily prevent a recipient from performing a process on a received email that the sender has not authorized, for example, and a great practical effect can be obtained.

FIG. switching network or network 100
Through the processing devices 110, 120 . ...130 are connected, and each processing device has a terminal 111...13, respectively.
2 are connected.

FIG. 2 is a block diagram showing an example of a processing device. The processing device 200 includes a storage device 220 for storing mail management information, etc., and a communication control device 230 connected to a communication circuit 260 and controlling communication with other processing devices. It is composed of a terminal control device 24o to which a plurality of terminals 250 are connected and controls the input/output of the terminals, and a control device 210 that controls each of these devices. functions such as creating, sending, receiving, and storing emails, as well as functions to control multiple post-reception processes that recipients perform on received emails, and a function that allows senders to decide whether or not post-reception processing is permitted for recipients. It provides a function to set the email header of the email you are trying to send, and a function that checks the header of the received email and prevents unauthorized post-reception processing.

FIG. 3 shows an example of the format of mail to be sent and received. The mail 300 is composed of mail headers 310 to 382 that store transmission management information such as destination and transmission mode (regular, urgent, registered mail, etc.), and a mail body 390 that stores information to be sent.

Whether or not post-reception processing is permitted by the recipient is 380-38
Set to 2. Number of post-reception processes prohibited to 380,
381,382. . . K Post-reception processing to be prohibited, for example, 1 printing 1' storage, 11 . . . forwarding, 1 substitute reception l, etc., can be set as many as 380.

When sending an email, the email sender responds as shown in Figure 5 and specifies whether or not processing on the receiving side is prohibited. In Figure 5, display and proxy reception are permitted, but printing and forwarding are prohibited. This designation is set in 388 to 382 of the email header shown in Figure 3.Including this setting, email header, email body creation, and email sending are conventional. The technology proposed by can be applied.

Reception (In IIl+, mail reception (8 recipients respond as shown in Figure 6. This indicates that printing is not possible because the recipient has already given permission.An example of this process on the receiving side is shown in the flowchart in Figure 4.The post-reception process selected by the recipient examines the email header of the received email. If it is prohibited, it will indicate that it is not permitted, and if it is not prohibited, it will execute the selected post-reception process.

In this way, the 5-line e-mail system can reliably and easily prevent recipients from performing processing that the sender has not authorized, such as printing or forwarding, on received mail. You can get amazing effects.

Note that the present invention is not limited to the above embodiments. For example, the post-reception processing is not limited to that shown in FIG. For the processing of creating, sending/receiving, and storing the mail header and mail body of the mail, various methods proposed in the past can be appropriately adopted.
