Abstract

PROBLEM TO BE SOLVED: To store a received document in a box and notify the stored document if the URL is set to be notified by e-mail even if a password is set in the box. There is a fear. In addition, when the received document is secure, it is a problem if the URL is accessed and the document is referred to unless the document is referred to while maintaining security.
E-Mail transmission is performed by encrypting a URL of a stored document.

Description

  The present invention relates to a system for accumulating received data in a storage device in the system in accordance with system settings, and notifying the accumulation of documents to a notification destination designated in advance.

  A digital multi-functional peripheral having a document box storage function and a transmission / reception means is exemplified. In such a system, it is possible to print a document read by a document reading device and stored in a box, or to store a received document in a designated box.

  In addition, when an image is stored in a specific box, an e-mail is sent to the mail address set in the box, and the storage position information of the document described in URL (Uniform resource Locator) is notified. Things are also done. In this case, the receiving side that receives the notification mail refers to the described URL and refers to the stored document using a Web browser or the like.

  Further, from the viewpoint of maintaining confidentiality during communication, communication is performed by encrypting the contents during communication. An example of such encrypted communication is e-mail transmission using SMIME. If encrypted transmission is instructed during transmission, the transmission data is encrypted and transmitted. If the received data is encrypted, the receiving device performs a decryption process so that it can be visualized at the time of printing or transferring.

For example, Patent Document 1 and Patent Document 2 can be cited as conventional examples.

  In the system, a means for encrypting the notification information and a means for storing a password for encrypting the notification information are provided, and when it is determined that the stored document is a confidential document, the document to be notified to the designated destination As a result, the location information is encrypted and the notification information is encrypted with the specified password, and the notification is sent to the set destination. When notified by e-mail, the received document has been encrypted from the security point of view, if the communication path is encrypted or the document itself is encrypted, even if the document is accessed by accessing a URL, security is maintained. You can refer to it in a lean state.

  Further, by encrypting the notification mail, it is possible to prevent the mail from being looked into and the document stored.

  Hereinafter, it will be described in detail with reference to the drawings.

  FIG. 1 shows a block diagram of a composite device to which this embodiment is applied.

  The composite device includes an image forming unit 101, a control unit 102, a finisher 103, a scanner unit 104, an operation unit 105, a plurality of reception interfaces 106, and a plurality of transmission interfaces 107. It is connected. The control unit 102 includes a central processing unit 108 and a storage device 109.

  FIG. 2 is a flowchart showing the processing of this embodiment.

  First, a document is received via the reception interface 106 (S201), and the setting being received stored in the storage device 109 is acquired (S202).

  Subsequently, the central processing unit determines whether or not the document received in S201 is set to be stored in the box (S203). If the determination in S203 is Yes, the document received in S201 is stored in the designated area on the storage device 109 according to the reception setting acquired in S202 (S204), and if No, the received received document is stored in the image forming unit 101, Printing is performed using the finisher 103 (S212), and the process ends.

  After the accumulation process in S204 is completed, the central processing unit 108 determines whether it is necessary to notify the accumulation of the document (S205). If the determination in S205 is Yes, the central processing unit 108 further encrypts and transmits the data itself, such as a document received and stored by encrypting the communication path, or SMIME e-mail. It is determined whether or not the document is a confidential document considering security (S206). If the determination in S205 is No, the process ends.

  If the determination in S206 is Yes, a URL accessible by HTTPS is generated as the position information of the document accumulated in S204 (S207), and if No, a URL accessible by HTTP is generated (S211).

  After S207 or S211, the notification destination set in the storage box is acquired (S208), the notification mail body is created (S209), and the storage notification mail is sent to the destination acquired in S208 (S210 ), The process ends.

  FIG. 4 shows a user box selection screen for storing documents, which is applied to this embodiment. A list of user boxes that can be used is displayed, and an item that is set to notify the accumulation of documents is displayed with an arrow icon indicating the user box.
