A first embodiment of the present invention will be described below with reference to the accompanying drawings.
FIG. 1 shows a system configuration for controlling and executing determination as to whether or not content can be transmitted and received as a portable terminal of the present invention. In FIG. 1, the portable terminal of the present invention includes a memory 1, a DB 2, a determination controller 3, a mail transmission unit 4, a mail reception unit 5, a DB 6, and a display controller 7. DB represents a database.

  The memory 1 temporarily stores content contents to be transmitted / received. DB2 holds keywords that are considered harmful. The determination controller 3 confirms the presence / absence of a keyword that is considered harmful from the content. The mail transmission unit 4 notifies that harmful information is accessed. The mail receiving unit 5 receives an access permission determination. As a result, the DB 6 holds an e-mail address recognized as harmful and a URL (Uniform Resource Locator) of the Web site. The display controller 7 determines whether or not harmful information can be displayed.

  In the portable terminal of the present invention, the memory 1 for temporarily storing the contents of contents to be transmitted / received may be secured in the form of being temporarily shared with the memory work area for storing the contents of the normally transmitted e-mail. Alternatively, the DB that holds the mail address determined to be harmful may be secured by adding a property such as a transmission permission flag to the telephone directory DB that is normally held in the mobile terminal.

  That is, the memory 1 stores information (contents content) of an e-mail or website received by the mobile terminal. At this time, the memory 1 is connected to a communication unit (not shown) that acquires e-mail or Web site information from the outside. The communication unit includes any or all of a communication interface, an antenna, and a transmission / reception data conversion circuit included in the mobile terminal. However, it is not limited to the above example. Note that the memory 1 may be connected to the mail receiver 5.

  The keywords held in DB2 are registered in advance. Alternatively, when the memory 1 acquires the e-mail or Web site information, the corresponding e-mail address or Web site URL is notified to the notification target through the mail transmission unit 4 unconditionally. If access is rejected by the access permission determination received by the mail receiving unit 5 in response to the notification, a predetermined word included in the title (subject name), body, email address, URL of the email or website All words are automatically extracted, and the extracted words are stored in the DB 2 as keywords. The word extraction is performed by a CPU (not shown) executing a word extraction processing program. This word extraction process can also be realized by a known technique or a known technique. For example, if an expected keyword is included, it is extracted. Alternatively, the word is extracted by breaking the syntax into words. In addition, you may make it receive a predetermined word with access permission judgment.

  The determination controller 3 monitors the memory 1 and refers to the keyword held in the DB 2 when some data is stored in the memory 1, and the content corresponding to the keyword in the data temporarily stored in the memory 1. Make sure that is not included. If it is included, the e-mail transmission unit 4 is notified.

  A target to be notified by the mail transmission unit 4 is a mobile phone or a personal computer of a third party who is a contractor of the mobile terminal, or other communication terminal capable of receiving e-mail. The partner who receives the notification is basically preferably a contractor of the portable terminal, but it may be changed to notify the other partner by setting. The notification means is not limited to electronic mail, but may be a short message service (SMS) or other notification means equivalent thereto. In addition, an option or button indicating “OK (access granted)” or “NG (access denied)” is displayed on the screen of a third-party communication terminal that is a contractor of the mobile terminal by the notification from the mail transmission unit 4 You may make it do. In this case, “OK (access permitted)” or “NG (access denied)” is selected by a third party who is a contractor of the mobile terminal, and the mail reception unit 5 receives the selection result as an access permission determination. To do. This can be realized by notifying by mail using a structured document (for example, an HTML document).

  Further, as another example of the access permission determination received by the mail receiving unit 5, it is considered that a person who has received the notification by the mail transmitting unit 4 describes and transmits information indicating the access permission determination in the reply mail for the notification. It is done. Alternatively, when the mail receiving unit 5 receives the reply mail in response to the notification from the mail transmitting unit 4, it is determined that the access is rejected regardless of the content of the reply mail. In this case, the reply mail may be a blank mail (mail without subject / text). If access is determined to be impossible as a result of the access permission determination, the CPU (not shown) may delete the contents stored temporarily in the memory 1.

  The e-mail address and the URL of the Web site stored in the DB 6 are not complete (full text), and a part of the e-mail address or URL can be used. For example, only the domain part of the e-mail address, that is, the part after the at sign (@) is used. Conversely, the account part, that is, the part before the at sign (@) may be used. Similarly, in the case of a URL, only the domain portion (eg, the “xxx” part of “http://www.xxx.com/”) is used. Alternatively, only the account / directory part (for example, “xxx” part of “http://www.xxx.com/xxx/”) is used. In many cases, the e-mail address and the URL of the Web site are common except for the characteristic part, and only the characteristic part data is retained, and other general parts are ignored. By doing so, it is possible to reduce the amount of data held in the DB 6.

  The display controller 7 controls the display screen of the mobile terminal. Therefore, after determining whether or not harmful information can be displayed, the display-permitted e-mail or website is displayed on the display screen. E-mails or Web sites that cannot be displayed are not displayed. Alternatively, a display indicating that it is not displayed or an error display is displayed. Here, the display-permitted e-mail or website is an e-mail or website that does not correspond to the data held in the DB 6. Conversely, an e-mail or website that cannot be displayed is an e-mail or website that corresponds to the data stored in the DB 6.

Next, the operation of the embodiment of the present invention will be described in detail with reference to the flowchart of FIG. FIG. 2 is a flowchart of an embodiment that takes up the case where transmission control of an e-mail created by a child is performed.

  The portable terminal of the present invention implements at least one of e-mail transmission control, e-mail reception control, and Web site access control shown in FIGS. Basically, it is desirable to implement everything.

Note that the mobile terminal of the present invention is not limited to a mobile terminal for children, but may be used for a company mobile terminal. For example, when a company has a mobile terminal contracted with a telecommunications carrier (carrier) to an employee of the company, the mobile terminal of the present invention can send and receive content including a keyword that is considered harmful to the employee. It becomes possible to restrict implementation.
As another example, if a keyword related to the business content is registered, if the employee transmits / receives the content content including the keyword related to the business content, the fact that the content content related to the business content is transmitted / received. It becomes possible to notify a third party (for example, a supervisor or superior). At this time, the contents may be notified together. This makes it possible for the company to grasp the transmission and reception of emails related to the work performed by the employees without waiting for reports from the employees. In addition, it is possible to prevent the transmission / reception of the mail related to the business contents to the unintended partner.

  As described above, the mobile terminal of the present invention has a DB that holds keywords (including e-mail addresses and URLs) regarded as harmful. It also has a function to update harmful keywords from outside the terminal. In addition, a determination controller is provided for confirming the presence / absence of a keyword that is harmful from the content of the content to be transmitted / received. Furthermore, it has a function of notifying (in advance) outside the terminal that harmful information is transmitted and received.
