Description

  The present invention relates to an information processing apparatus, an information processing method, and a program.

  In recent years, large-scale information leakage incidents are increasing with the increase in the speed of transmission paths. In addition, the demand for information leakage prevention is increasing due to the establishment of new laws. The cause of information leakage is intentional information leakage, but erroneous transmission due to erroneous operation of e-mail software or an error in the transmission destination accounts for a large percentage.

Various techniques for preventing erroneous transmission have been proposed, and the techniques are mainly divided into two techniques: a technique for detecting an erroneous transmission by inspecting an electronic mail itself and a technique for canceling an erroneously transmitted mail after a transmission instruction.
As a technique for inspecting the e-mail itself, Patent Document 1 searches a keyword (for example, an address) set for an e-mail address designated as a transmission destination, and checks for inconsistency between the address and the keyword depending on the presence or absence of the keyword in the text. However, a technique for preventing erroneous transmission is disclosed.

JP 2007-060157 A

However, in the technique disclosed in Patent Document 1, when a keyword (for example, an address) in the body of an e-mail is associated with a plurality of e-mail addresses (for example, a plurality of e-mail addresses are registered for a person with the same surname). There is a problem that cannot be resolved.
Further, even if an address corresponding to a mail address designated as a transmission destination is searched and inconsistency is checked, an e-mail may not be transmitted (transmission omission) to a destination (transmission destination) to be transmitted.

The present invention has been made in view of such problems, and an object thereof is to resolve ambiguity and prevent erroneous transmission of electronic mail.
Another object of the invention is to prevent omission of e-mail transmission according to a mail address designated as a destination and a keyword in the body of the e-mail.

  Therefore, the present invention searches for address information in which a mail address is associated with a mail address using a mail address specifying means for specifying the mail address from the body of the e-mail and the mail address specified by the mail address specifying means. A mail address specifying means for specifying a mail address corresponding to the address specified by the address specifying means; and a plurality of mail addresses specified by the mail address specifying means, indicating that a plurality of mail addresses are specified. Warning means for displaying a screen including warning information on a display device.

  The present invention is also an information processing method in the information processing apparatus, wherein the address specifying unit of the information processing apparatus specifies an address from the body of an electronic mail, and the mail address specifying unit of the information processing apparatus However, the mail address corresponding to the mail address specified in the mail address specifying step is specified by searching the address information in which the mail address is associated with the mail address using the mail address specified in the mail address specifying step. When a plurality of e-mail addresses are specified in the e-mail address specifying step, an e-mail address specifying step and a warning unit of the information processing apparatus display a screen including warning information indicating that a plurality of e-mail addresses have been specified on the display device And a warning step to be displayed.

According to the present invention, ambiguity can be resolved and erroneous transmission of electronic mail can be prevented.
Further, according to the present invention, it is possible to prevent omission of e-mail transmission according to the e-mail address specified as the recipient and the keyword in the e-mail body.

The mail server 160 transmits an electronic mail transmitted from the information processing apparatus 100 via the network 150 to the outside of the network.

FIG. 3 is a flowchart illustrating an example of basic processing related to prevention of erroneous email transmission in the information processing apparatus. Note that the processing shown in FIG. 3 is executed when transmission is instructed from the editing state of the e-mail.
In step S301, the address specification processing unit 141 scans the body of the e-mail created by the body creating unit 120 to detect the address attribute character string stored in the address book 130, and the position of the address attribute character string. Specify the destination address from the relationship. Details of the processing in step S301 will be described with reference to FIG.

In step S <b> 302, the address address specification processing unit 142 specifies an e-mail address (address address) corresponding to the address specified in step S <b> 301 with reference to the address book 130.
In step S303, the address inspection processing unit 143 checks the consistency between the destination address specified in step S302 and the transmission destination e-mail address (transmission destination address) specified by the transmission destination address specification unit 110. Details of the processing in step S303 will be described with reference to FIG.

  In step 304, the transmission control processing unit 144 determines whether there is a mismatch based on the inspection result in step S303. If it is determined that there is a mismatch, the transmission control processing unit 144 proceeds to step S305, and if it is determined that there is no mismatch, the process proceeds to step S306.

In step S305, the transmission control processing unit 144 displays an error message indicating that the destination address is inconsistent with the text destination, does not send an e-mail, and ends the process shown in FIG.
On the other hand, in step 306, the transmission control processing unit 144 transmits an e-mail and ends the processing shown in FIG.

  Next, as a more specific example, the process of FIG. 3 will be described using an example in which the e-mail shown in FIG. 5 is transmitted using the address book 130 shown in FIG. FIG. 4 is a diagram (part 1) illustrating an example of an address book. FIG. 5 is a diagram (part 1) illustrating an example of an electronic mail.

  In step S301, the address specification processing unit 141 performs the character string 502 ("Uneven Trading"), the character string 503 ("Sato"), and the character string 504 ("Δ □ Industrial" shown in FIG. ") And three addressing attribute character strings are detected. Then, the address specification processing unit 141 specifies the address of {character string 502 (“uneven trading”), character string 503 (“Sato”)} from the positional relationship of the detected address attribute character strings. A method for specifying the address will be described later.

  In step S302, the address address specification processing unit 142 selects an address that matches the attribute included in the address of {character string 502 ("uneven trading"), character string 503 ("Sato")} as shown in FIG. Acquired from the book 130. More specifically, the address address specification processing unit 142 performs the address address 401 (“sato.kazuo@dekoboko.jp”) corresponding to the address {attribute 402 (“uneven trading”), attribute 403 (“Sato”)}. ) Is identified and acquired. In other words, the address address identification processing unit 142 uses a character string 502 (“uneven trading”) and a character string 503 (“Sato”), which are character strings included in the address, to generate a plurality of address attributes, e-mail addresses, Are searched for the address book 130 associated with. The address address identification processing unit 142 then sends the mail address of the address information in which the character string 502 (“uneven trading”) and the character string 503 (“Sato”) match all or some of the plurality of address attributes. ("Sato.kazuo@dekoboko.jp") is specified.

  In step S <b> 303, the address inspection processing unit 143 acquires the transmission destination address (“sato.kazuo@dekoboko.jp”) specified by the transmission destination address specifying unit 110. Then, the address inspection processing unit 143 compares the destination address (“sato.kazuo@dekoboko.jp”) with the destination address 401 (“sato.kazuo@dekoboko.jp”), and checks the consistency. .

In step S304, the transmission control processing unit 144 determines that there is no inconsistency as a result of the inspection in step S303, and moves the process to step S306.
In step S306, the transmission control processing unit 144 transmits the email shown in FIG. 5 and ends the process shown in FIG. Note that the transmission control processing unit 144 sends a combination of the destination address of the e-mail and the e-mail when the e-mail instructed to be transmitted has a specific attribute or an unspecified attribute described later before transmitting the e-mail. The group address (character string) in the body of the mail is stored in a transmission result table to be described later.

Next, details of the address specifying process in step S301 will be described with reference to FIG. FIG. 6 is a flowchart illustrating a detailed example of address identification processing according to the first embodiment.
In step S <b> 601, the address specification processing unit 141 empties the address storage area secured on the RAM 203.

In step S <b> 602, the address specification processing unit 141 clears the address buffer secured on the RAM 203.
In step S603, the address specification processing unit 141 sets the head of the text string (text text string) acquired from the text creation unit 120 as the scanning position.

In step S <b> 604, the address specification processing unit 141 starts a process of repeating until the scanning position comes to the end of the text string acquired from the text creation unit 120.
In step S605, the address specification processing unit 141 searches the address attribute character strings included in the address book 130 for an address attribute character string that matches a partial character string starting from the scanning position of the text character string.

  In step S606, the address specification processing unit 141 determines whether there is an address attribute character string that matches the character string starting from the scanning position of the text string in step S605 (whether it has been detected). If there is an address attribute character string that matches the character string starting from the scanning position, the address specification processing unit 141 proceeds to step S607, and there is no address attribute character string that matches the character string starting from the scanning position. If so, the process moves to step S611.

  In step S607, the address specification processing unit 141 determines whether the address buffer is empty or the address attribute character string detected in step S605 can be connected to the address buffer. If the address buffer is empty or the address attribute character string can be connected to the address buffer, the address specification processing unit 141 proceeds to step S608. If the address buffer is not empty and the address attribute character string is not connectable to the address buffer, the address specification processing unit 141 proceeds to step S613.

Here, a method for determining whether or not an address attribute character string can be connected to the address buffer will be described. FIG. 7 is a diagram (part 1) illustrating an example of a connection order table in which attribute connection orders in the address buffer are defined. For example, the connection order table is stored in the external memory 211 or the like.
When registering the address attribute character string in the address buffer, the address specification processing unit 141 stores the attribute connection order for the address attribute character string registered in the address buffer last time and the attribute connection order for the address attribute character string to be registered. , Compare.
The address specification processing unit 141 determines that connection to the address buffer is possible if the attribute connection order for the address attribute character string to be registered is greater than or equal to the attribute connection order for the previously registered address attribute character string. .

Returning to the description of FIG. 6 again, in step S608, the address specification processing unit 141 adds the address attribute character string detected in step S605 to the address buffer.
In step S609, the address specification processing unit 141 advances the scan position by the length of the processed character string. More specifically, when the address identification processing unit 141 detects an address attribute character string in step S605, the address specification processing unit 141 advances the scanning position by the length of the detected address attribute character string in step S609. If the address attribute character string is not detected in step S605, the address specification processing unit 141 advances the scanning position by one character.

In step S610, the address specification processing unit 141 returns the process to step S604 if the scanning position is not the end of the text. On the other hand, if the scanning position is the end of the text, the address specification processing unit 141 proceeds to step S615.
In step S611, the address specification processing unit 141 acquires one character from the scanning position, and determines whether or not the acquired character is a preset non-target character. The address specification processing unit 141 proceeds to step S609 if the character is not a target character, and moves to step S612 if the character is not a target character. Examples of non-target characters include a space character, a tab character, and a line feed character.

In step S612, the address specification processing unit 141 determines whether the address buffer is empty. If the address buffer is empty, the address specification processing unit 141 proceeds to step S609, and if not, the process proceeds to step S613.
In step S613, the address specification processing unit 141 adds the contents of the address buffer as one address to the address storage area secured on the RAM 203, and emptys the address buffer. The address specification processing unit 141 does not add the contents of the address buffer to the address storage area when there is no address attribute character string in which “required” of the attribute of the address attribute character string registered in the address buffer is TRUE. .

In step S614, the address specification processing unit 141 adds the address attribute character string detected in step S605 to the address buffer when there is an address attribute character string (that is, in the case of branching from step S607).
In step S615, the address specification processing unit 141 determines whether the address buffer is empty. If the address buffer is empty, the address specification processing unit 141 ends the process illustrated in FIG. 6. If the address buffer is not empty, the address specification processing unit 141 proceeds to step S616.
In step S616, the address specification processing unit 141 adds the contents of the address buffer as one address to the address storage area secured on the RAM 203, and ends the process shown in FIG. The address specification processing unit 141 does not add the contents of the address buffer to the address storage area when there is no address attribute character string in which “required” of the attribute of the address attribute character string registered in the address buffer is TRUE. .

As a more specific example, the process of FIG. 6 will be described by taking the case of sending the e-mail of FIG. 5 as an example.
First, the address specification processing unit 141 executes the processing from steps S601 to S604.
In step S605, the address identification processing unit 141 obtains the attribute 402 (“convex and traded”) that is a matching address attribute character string because the scanning position is at the head position of the character string 502 (“convex and traded”). Therefore, in step S606, the address specification processing unit 141 determines that there is an address attribute character string, and moves the process to step S607.

In step S607, the address specification processing unit 141 moves the process to step S608 because the address buffer is empty.
In step S608, the address specification processing unit 141 adds an attribute 402 (“uneven trading”), which is an address attribute character string, to the address buffer, and the process proceeds to step S609.
In step S609, the address specification processing unit 141 advances the scanning position by the length of the character string 502 (“uneven trading”), and moves to step S610.
In step S610, the address identification processing unit 141 proceeds to step S605 because the scanning position is not the end of the text.

In step S605, the address specification processing unit 141 cannot obtain a matching address attribute character string because the scanning position is a line feed character.
Therefore, in step S606, the address specification processing unit 141 determines that there is no address attribute character string, and moves the process to step S611.
In step S611, the address identification processing unit 141 determines that the character at the scanning position is a line feed character, and thus determines that the character is not a target, and moves the process to step S609.
In step S609, the address specification processing unit 141 advances the scanning position by one character and moves to step S610.
In step S610, the address identification processing unit 141 proceeds to step S605 because the scanning position is not the end of the text.

In step S605, the address identification processing unit 141 obtains the attribute 403 (“Sato”) that is the matching address attribute character string because the scanning position is at the head position of the character string 503 (“Sato”). Therefore, in step S606, the address specification processing unit 141 determines that there is an address attribute character string, and moves the process to step S607.
In step S <b> 607, the address specification processing unit 141 indicates that the address buffer is not empty, the attribute 402 (“convex trading”) that is the address attribute character string added to the previous address buffer, and the address attribute character string to be added. The connection order of the attribute 403 (“Sato”) is compared. The attribute 402 (“Uneven Trading”) is “organization” and the connection order is 1, the attribute “Last Name” is the attribute 403 (“Sato”), and the connection order is 3. Therefore, the address identification processing unit 141 determines that connection is possible, and moves the process to step S608.

In step S608, the address specification processing unit 141 adds the attribute 403 (“Sato”), which is an address attribute character string, to the address buffer, and moves the process to step S609.
In step S609, the address specification processing unit 141 advances the scanning position by the length of the character string 503 (“Sato”), and moves to step S610.
In step S610, the address specification processing unit 141 moves the process to step S605 because the scanning position is not the end of the text.

In step S605, the address specification processing unit 141 cannot obtain a matching address attribute character string because the scanning position is the next character ("like") after the character string 503 ("Sato").
Therefore, in step S606, the address specification processing unit 141 determines that there is no address attribute character string, and moves the process to step S611.
In step S611, the address specification processing unit 141 determines that the character at the scanning position is “like” and is not a non-target character, and the process proceeds to step S612.
In step S612, the address specification processing unit 141 proceeds to step S613 because the address buffer is not empty.

In step S613, the address specification processing unit 141 adds the contents of the address buffer ({attribute 402 ("uneven trading"), attribute 403 ("Sato")}) to the address storage area on the RAM 203 as the address, and the address buffer. And the process proceeds to step S614.
In step S614, the address specification processing unit 141 does not perform any processing since it is not a branch from step S607, and moves on to step S609.

Thereafter, the same processing is executed, and when the scanning position is the head position of the character string 504 (“Δ □ industrial”), the address specifying processing unit 141 stores {attribute 404 (“Δ □ industrial” in the address buffer). Add ")}. Further, the address identification processing unit 141 executes the process of step S613 or step S616. However, at this time, the address attribute character string stored in the address buffer is only {attribute 404 (“Δ □ industry”)}. Since the “attribute” of {attribute 404 (“Δ □ industry”)} is an organization and the “required” item is FALSE from the connection order table, the address specification processing unit 141 uses {attribute 404 (“Δ □ industry”). Do not add ")} to the address storage area.
Therefore, in the example of sending the e-mail of FIG. 5, when the processing of FIG. 6 is completed, the address ({attribute 402 ("convex trading"), attribute 403 ("Sato")}) is stored in the address storage area. It is remembered.

  The address specification processing unit 141 may handle a title or title as a special address attribute character string. For example, scan the name of the last name or the first name followed by a character string such as “sama” or “dono”, or the title of a title such as “director”. If there is a title or title, the address buffer is stored in the address storage area. If there is no title or title, a process for emptying the address buffer may be added. In this way, for example, the electronic mail in FIG. 5 will be described as an example. Even when there is no character string 502, character string 503, etc., the character string 505 ("Yamada") is stored in the address storage area as the address. Can be prevented. That is, by doing in this way, when there is no character string 502, character string 503, etc., it can be set as an error by processing as shown in Drawing 9 mentioned below.

  The address specification processing unit 141 may specify an address using a morphological analysis, an analyzer using a regular expression, or the like.

Next, the address address specifying process in step S302 will be described.
The address address specification processing unit 142 specifies an address for each address stored in the address storage area on the RAM 203 by the address specification processing unit 141.
More specifically, the address address specification processing unit 142 acquires, from the address book 130, addresses having all attribute character strings included in the address as address addresses. The address address specification processing unit 142 stores the acquired address address in association with the address stored in the address storage area on the RAM 203. In addition, when there are two or more (that is, a plurality of) address addresses corresponding to one address, the address address specifying processing unit 142 gives an ambiguous attribute to the address.

  Here, another example of the address book 130 is shown in FIG. FIG. 8 is a second diagram illustrating an example of an address book. In the case of the address book 130 of FIG. 8, the address address specification processing unit 142 uses the address ({attribute 402 (“uneven trading”), attribute 403 (“Sato”)}) to address address 401 corresponding to the address. And a destination address 801 are specified. Since there are two address addresses, the address address specification processing unit 142 assigns an ambiguous attribute to the address ({attribute 402 (“uneven trading”), attribute 403 (“Sato”)}).

  Suppose that the address is {attribute 402 ("uneven trading"), attribute 403 ("Sato"), attribute ("sales department")}, or {attribute 402 ("uneven trading"), attribute 403 ("Sato"), Attribute (“Kazuo”)}. Then, the address address specification processing unit 142 specifies one address address 401 (“sato.kazuo@dekoboko.jp”) from the address book of FIG. 8, and therefore does not give an ambiguous attribute to the address.

Next, the address inspection process in step S303 will be described with reference to FIG. FIG. 9 is a flowchart illustrating a detailed example of the address inspection process according to the first embodiment.
In step S <b> 901, the address inspection processing unit 143 empties the error area secured on the RAM 203.
In step S <b> 902, the address inspection processing unit 143 starts the iterative processing for the address stored in the address storage area on the RAM 203 associated with the address specified by the address address specifying processing unit 142.

In step S903, the address inspection processing unit 143 determines whether or not an ambiguous attribute is given to the address. If the ambiguous attribute is assigned, the address inspection processing unit 143 moves the process to step S904, and if the ambiguous attribute is not given, moves the process to step S905.
In step S <b> 904, the address inspection processing unit 143 adds an ambiguous error to the error area secured on the RAM 203.

  On the other hand, in step S905, the address inspection processing unit 143 determines whether the address address associated with the processing target address is not in the e-mail destination address specified by the destination address specifying unit 110. judge. If the address address associated with the address to be processed is not included in the e-mail transmission destination address specified by the transmission destination address specifying unit 110, the address inspection processing unit 143 moves the process to step S906. If the address address associated with the processing target address is in the e-mail transmission destination address designated by the transmission destination address designation unit 110, the address inspection processing unit 143 moves the process to step S907.

In step S <b> 906, the address inspection processing unit 143 adds a destinationless error to the error area secured on the RAM 203.
In step S907, the address inspection processing unit 143 determines whether the address address associated with the processing target address is in the address specified in the BCC field of the email by the transmission destination address specifying unit 110. To do. If the address address associated with the address to be processed is in the address specified in the BCC field of the e-mail by the destination address specifying unit 110, the address inspection processing unit 143 moves the process to step S908. On the other hand, if the address address associated with the address to be processed is not in the address specified in the BCC field of the e-mail by the destination address specifying unit 110, the address inspection processing unit 143 performs the process in step S909. Transfer.

In step S908, the address inspection processing unit 143 adds a BCC error to the error area secured on the RAM 203.
In step S909, if there is an unprocessed address stored in the address storage area on the RAM 203, the address inspection processing unit 143 proceeds to step S903. If the address stored in the address storage area on the RAM 203 does not have an address that has not been processed, the address inspection processing unit 143 ends the repetitive processing and moves the process to step S910.

In step S <b> 910, the address inspection processing unit 143 starts the iterative process for the transmission destination address specified by the transmission destination address specifying unit 110 (that is, the addresses specified in the To field, CC field, and BCC field). .
In step S911, the address inspection processing unit 143 determines whether the transmission destination address to be processed is included in the address address associated with the address stored in the address storage area on the RAM 203. If it is not included in the address, the address inspection processing unit 143 moves the process to step S912. If it is included in the address, the address check processing unit 143 moves the process to step S914.

  In step S912, the address inspection processing unit 143 determines whether or not the transmission destination address to be processed is an address in the address specified in the BCC field of the email by the transmission destination address specifying unit 110. If the destination address to be processed is an address that is in the address specified in the BCC field of the email by the destination address specifying unit 110, the address inspection processing unit 143 moves the process to step S914. On the other hand, if the destination address to be processed is an address not included in the address specified in the BCC field of the electronic mail by the destination address specifying unit 110, the address inspection processing unit 143 moves the process to step S913.

In step S <b> 913, the address inspection processing unit 143 adds an addressless error to the error area secured on the RAM 203.
In step S914, if there is an unprocessed transmission destination address among the transmission destination addresses specified by the transmission destination address specifying unit 110, the address inspection processing unit 143 moves the process to step S911. If there is no unprocessed transmission destination address among the transmission destination addresses specified by the transmission destination address specifying unit 110, the address inspection processing unit 143 ends the repetitive processing and ends the processing shown in FIG.

More specifically, the address address 401 (“sato.kazuo@dekoboko.jp”) is assigned to the address ({attribute 402 (“uneven trading”), attribute 403 (“Sato”)}) according to the address book of FIG. The process of FIG. 9 will be described by taking as an example a case in which the
First, the address inspection processing unit 143 executes processing from steps S901 to S902.

  In step S903, the address inspection processing unit 143 determines an ambiguous attribute for the address ({attribute 402 ("uneven trading"), attribute 403 ("Sato")}). Since the address is associated with one address, the ambiguous attribute is not given, and the address check processing unit 143 moves the process to step S905.

In step S <b> 905, the address inspection processing unit 143 determines whether or not the destination address 401 (“sato.kazuo@dekoboko.jp”) is specified as the transmission destination address by the transmission destination address specification unit 110.
If the destination address 401 is not specified as the transmission destination address by the transmission destination address specifying unit 110, the address inspection processing unit 143 adds a transmission destination no error to the error area secured on the RAM 203 in step S906.

When the destination address 401 is specified in the transmission destination address specifying unit 110, the address inspection processing unit 143 determines whether or not the destination address 401 is specified in the BCC field in step S907. If the destination address 401 is specified in the BCC field by the transmission destination address specifying unit 110, the address inspection processing unit 143 moves the process to step S908. In step S908, the address inspection processing unit 143 adds a BCC error to the error area secured on the RAM 203.
If the destination address 401 is not specified in the BCC field by the transmission destination address specifying unit 110, the address inspection processing unit 143 moves the process to step S909. In step S909, the address check processing unit 143 moves the process to step S910 because there is no unprocessed address in the address storage area on the RAM 203.
The subsequent description is omitted.

Next, according to the address book of FIG. 8, for the address ({attribute 402 ("uneven trading"), attribute 403 ("Sato")}), the address address 401 ("sato.kazuo@dekoboko.jp") and the address The process of FIG. 9 will be described by taking as an example the case where the address 801 (“sato.kazuko@dekoboko.jp”) is associated.
First, the address inspection processing unit 143 executes processing from steps S901 to S902.

In step S903, the address inspection processing unit 143 determines an ambiguous attribute for the address ({attribute 402 ("uneven trading"), attribute 403 ("Sato")}). Since the address has two address addresses associated with it, an ambiguous attribute is given, and the address inspection processing unit 143 moves the process to step S904.
In step S <b> 904, the address inspection processing unit 143 adds an ambiguous error to the error area secured on the RAM 203.
The subsequent description is omitted.

Next, the error display process in step S305 will be described.
In step S305, the transmission control processing unit 144 displays a warning screen including warning information (warning message) as shown in FIG. 10, for example, according to the error type stored in the error area secured on the RAM 203. FIG. 10 is a diagram illustrating an example of a warning screen. FIG. 11 is a diagram for explaining an error type and an example of a warning message corresponding to the error type.

  The warning screen shown in FIG. 10 shows an example of a warning screen when the error type is an ambiguous error. FIG. 10 shows a part of a plurality of address attributes (namely, first name and last name) associated with address information in the mail address “sato.kazuo@dekoboko.jp” specified by the address address specifying processing unit 142. Is displayed. FIG. 10 also shows a part of a plurality of mail address attributes (namely, surname and name) associated with the mail address “sato.kazuko@dekoboko.jp” identified in the mail address identification processing unit 142 in the address information. Name) is displayed. In FIG. 10, as an example, only a part of the plurality of address attributes associated with the email address and the address information is displayed, but all of the plurality of address attributes (for example, last name, first name, organization, department, E-mail address) may be displayed.

  In addition, when the error type is an ambiguous error, as shown in FIG. 10, the warning screen is an example of a selection designation unit that can select a person to whom the address is to be transmitted in order to resolve the ambiguity. A radio button is displayed. In response to a selection instruction via a radio button or the like on the warning screen, the transmission control processing unit 144 uses an e-mail address uniquely specified from all or some of the plurality of selected address attributes as an e-mail transmission destination. Set.

  As described above, according to the present embodiment as described above, ambiguity can be resolved and erroneous transmission of electronic mail can be prevented. In addition, according to the present embodiment, it is possible to prevent erroneous transmission of an e-mail by detecting a state where the correspondence between the address and the destination address cannot be obtained and prompting the user to confirm. In addition, according to the present embodiment, information leakage is suppressed by detecting that the address corresponding to the address specified in the BCC field is included in the body of the e-mail and prompting the user to confirm. Can do.

<Embodiment 2>
In the second embodiment, an address indicating a specific number or unspecified number such as “relationships” or “customers” is set as a group address, and the information processing apparatus 100 performs processing for each specified / unspecified group address Will be explained. In the present embodiment, differences from the first embodiment will be mainly described.

FIG. 12 is a diagram illustrating an example of the group address table. The group address table shown in FIG. 12 is stored in the external memory 211, for example.
The group address character string cannot be connected to any attribute character string including the group address character string itself. Further, it is assumed that the group address character string is established as a single address.
For the group address character string, either a specific attribute or an unspecific attribute is given based on the group address table. Here, the unspecified attribute is an attribute relating to a group that is set so as not to disclose the mail address between the groups. The specific attribute is an attribute related to a group that is set to open a mail address between groups.

  In the second embodiment, the address specification processing unit 141 also detects the group address in step S605 of FIG.

FIG. 13 is a flowchart illustrating a detailed example of the address checking process in the second embodiment. In FIG. 13, steps similar to those in FIG. 9 are assigned the same step numbers as in FIG. 9, and descriptions thereof are omitted.
In step S1101, the address inspection processing unit 143 determines whether the address stored in the address storage area on the RAM 203 is a group address. The address inspection processing unit 143 moves the process to step S1102 if the address is a group address, and moves the process to step S903 if the address is not the group address.

In step S1102, the address inspection processing unit 143 determines that the e-mail to be transmitted is addressed to a specific or unspecified sender based on the specification or unspecified attribute of the group address character string corresponding to the group address. Is stored in the RAM 203.
In step S1103, the address inspection processing unit 143 determines whether the transmission destination address to be processed is set in the To field or the CC field. If it is set in the To field or the CC field, the address inspection processing unit 143 moves the process to step S1104. If it is not set in the To field or the CC field, the address inspection processing unit 143 moves the process to step S911.

In step S1104, the address inspection processing unit 143 determines whether or not an unspecified attribute is set in step S1102 for the transmission destination address to be processed. When the unspecified attribute is set for the processing destination address, the address inspection processing unit 143 moves the process to step S1105, and the unspecified attribute is not set for the processing destination address. If so, the process moves to step S911.
In step S <b> 1105, the address inspection processing unit 143 adds an unspecified address error to the error area secured on the RAM 203.

In step S1106, the address inspection processing unit 143 determines whether or not a specific attribute is set in step S1102 for the transmission destination address to be processed. If the specific attribute is set for the processing destination address, the address inspection processing unit 143 moves the process to step S1107, and if the specific attribute is not set for the processing destination address, The process moves to step S912.
In step S1107, the address inspection processing unit 143 determines whether the domain of the transmission destination address to be processed is the same as the domain of the e-mail address of the transmission source. If the domain of the destination address to be processed is the same as the domain of the source e-mail address, the address inspection processing unit 143 moves the process to step S914, and if not, moves the process to step S913. .

In step S1108, the address inspection processing unit 143 determines whether or not an unspecified attribute or a specific attribute is set in step S1102 for the transmission destination address specified by the transmission destination address specifying unit 110. If the unspecified attribute or the specific attribute is set in step S1102 for the transmission destination address specified by the transmission destination address specifying unit 110, the address inspection processing unit 143 advances the processing to step S1109. On the other hand, if the unspecified attribute or the specific attribute is not set in step S1102 for the transmission destination address specified by the transmission destination address specifying unit 110, the address inspection processing unit 143 ends the processing illustrated in FIG. .
In step S1109, the address inspection processing unit 143 determines whether or not there is a transmission record in the past with respect to the combination (combination) of the transmission destination addresses specified by the transmission destination address specification unit 110. As a result of the determination, If there is no transmission record, an error process is executed.
Details of the processing in step S1109 will be described with reference to FIG.

FIG. 14 is a flowchart illustrating a detailed example of the transmission performance inspection process.
In step S2101, the address inspection processing unit 143 searches the transmission result table for the same combination as the combination (combination) of the transmission destination addresses specified by the transmission destination address specifying unit 110. Here, FIG. 15 is a diagram illustrating an example of a transmission record table. If the group's address (e.g., each) is included in the body text of the email, the transmission result table includes a set of email addresses set as the destination of the email and the address in the body of the email. It is a table for associating each other and storing it as transmission record information. As shown in FIG. 15, the transmission record table has “transmission destination” and “group address character string” as items. “Destination” stores a set of email addresses set as destinations of emails transmitted in the past. The “group address character string” stores the address of the group in the body of the e-mail.

  Returning to the description of FIG. 14 again, in step S2102, if the address inspection processing unit 143 searches the transmission record table for the same combination as the combination of the destination addresses of the e-mail as a result of the search in step S2101, the process proceeds to step S2103. Move processing. On the other hand, if the same combination as the destination address group does not exist in the transmission record table, the address inspection processing unit 143 moves the process to step S2104.

In step S2103, the address inspection processing unit 143 sends the group address corresponding to the group of addresses searched in step S2101 to the group address in the body of the e-mail instructed to transmit (to be transmitted). It is determined whether or not it matches the character string. If the group address (character string) matches, the address inspection processing unit 143 ends the process shown in FIG. 14. If the group address (character string) does not match, the address inspection processing unit 143 proceeds to step S2104.
In step S <b> 2104, the address inspection processing unit 143 adds an error with no transmission record to the error area secured on the RAM 203.

  Next, as a more specific example, the process of FIG. 13 will be described with reference to an example in which the electronic mail shown in FIG. 16 is to be transmitted. FIG. 16 is a second diagram illustrating an example of electronic mail. When the e-mail in FIG. 16 is about to be transmitted, the address specification processing unit 141 and the address address specification processing unit 142 start from the text string 1201 (“relationship level”) to the address ({group attribute (“relationship level”, Get "specific")}).

In step S <b> 902, the address inspection processing unit 143 starts processing for the address ({group attribute (“relationship”, “specific”)}).
In step S1101, the address inspection processing unit 143 determines that the address ({group attribute (“relationship”, “specific”)}) is a group address, and the process proceeds to step S1102.

In step S1102, the address inspection processing unit 143 sets the specific attribute for the mail to be transmitted because the address ({group attribute ("relationship", "specific")}) has the specific attribute. Remember above.
Thereafter, processing is executed in the same manner as in the first embodiment up to S909.
In step S <b> 910, the address inspection processing unit 143 starts processing for the transmission destination address 1202 (“yamamoto.keiko@sankaku.jp”) that is the transmission destination.

In step S1103, the address inspection processing unit 143 proceeds to step S1104 because the transmission destination address 1202 (“yamamoto.keiko@sankaku.jp”) is specified in the To field.
In step S1104, the address inspection processing unit 143 determines that there is no unspecified attribute for the processing destination address (or e-mail) on the RAM 203, and moves the process to step S911.

In step S911, the address inspection processing unit 143 moves the process to step S1106 because the transmission destination address 1202 (“yamamoto.keiko@sankaku.jp”) to be processed is not in the address.
In step S1106, the address inspection processing unit 143 determines that the specific attribute for the electronic mail is set (or stored) on the RAM 203, and the process proceeds to step S1107.

In step 1107, the address inspection processing unit 143 determines that the domain of the transmission destination address 1202 (“yamamoto.keiko@sankaku.jp”) is equal to the transmission source address 1205 (“nakakata.hideyoshi@sankaku.jp”), The process moves to step S914.
Thereafter, the address inspection processing unit 143 performs the same process on the transmission destination address 1203 (“yamada.jiro@sankaku.jp”).

After that, in step S910, the address inspection processing unit 143 starts processing on the transmission destination address 1204 ("suzuki.daisuke@dekobo.jp") that is the transmission destination.
In step S1103, the address inspection processing unit 143 moves the process to step S1104 because the transmission destination address 1202 (“suzuki.daisuke@dekoboko.jp”) is specified in the To field.

In step S1104, the address inspection processing unit 143 determines that there is no unspecified attribute for the transmission destination address (or e-mail) to be processed in the RAM 203, and moves the process to S911.
In step S911, the address inspection processing unit 143 moves the process to step S1106 because the transmission destination address 1204 (“suzuki.daisuke@dekobo.jp”) to be processed is not in the destination address.

In step S1106, the address inspection processing unit 143 determines that the specific attribute for the electronic mail is set (or stored) on the RAM 203, and the process proceeds to step S1107.
In step 1107, the address inspection processing unit 143 determines that the domain of the transmission destination address 1204 ("suzuki.daisuke@dekoboko.jp") is different from the transmission source address 1205 ("nakata.hideyoshi@sankaku.jp"), The process moves to step S912.

In step S912, the address inspection processing unit 143 determines that the processing destination address 1204 ("suzuki.daisuke@dekoboko.jp") is not an address specified in the BCC field of the email. Then, the process proceeds to step S913.
In step S <b> 913, the address inspection processing unit 143 adds an addressless error to the error area secured on the RAM 203 with respect to the transmission destination address 1204 (“suzuki.daisuke@dekoboko.jp”).
In step S914, the address check processing unit 143 moves the process to step S1108 because there is no unprocessed destination address.

In step S1108, the address inspection processing unit 143 determines that the specific attribute for the electronic mail is set (or stored) on the RAM 203, and the process proceeds to step S1109.
In step S1109, the address inspection processing unit 143 starts processing from step S2101 in FIG. 14 in order to execute transmission performance inspection processing.
In step S2101, the address inspection processing unit 143 transmits the destination, destination address 1202 ("yamamoto.keiko@sankaku.jp"), and destination address 1203 ("yamada.jiro@sanku. jp ") and the transmission address including the transmission destination address 1204 (" suzuki.daisuke@dekoboko.jp ") are searched from the transmission result table.

In step S2102, the address inspection processing unit 143 moves the processing to step S2103 because there is a transmission record having the same combination as the combination of e-mail destination addresses in the transmission result table as a result of the search in step S2101.
In step S2103, the address inspection processing unit 143 terminates the processing because the group address in the email to be transmitted matches the group address character string in the transmission record searched in step S2101 and is in the same relationship. .

  As described above, according to the above-described embodiment, it is possible to suppress information leakage due to the fact that the address corresponding to the address specified in the BCC field is included in the text. In addition, according to the present embodiment, when mail transmission is performed with an unspecified number as a destination, the possibility of disclosing each other's e-mail address to the unspecified number can be reduced.

<Embodiment 3>
In the third embodiment, a process in which the information processing apparatus 100 sets a scanning range and identifies an address will be described. In the present embodiment, differences from the above-described embodiment will be mainly described.

FIG. 17 is a flowchart illustrating a detailed example of address identification processing according to the third embodiment.
In step S1301, the address specification processing unit 141 sets a scanning range (range setting). More specifically, the address specification processing unit 141 designates the scanning range by the number of lines from the top of the text, the number of characters, or the like. The number of lines or the number of characters may be described in advance in a file or the like stored in the external memory 211, or the address identification processing unit 141 may determine the number according to the number of destination mail addresses. Good. For example, the address specification processing unit 141 sets the scanning range by multiplying the number of destination mail addresses by a certain number (for example, two lines).

In step S1302, the address specification processing unit 141 determines whether the scanning position is outside the scanning range set in step S1302. If the scanning position is out of the range, the address identification processing unit 141 interrupts the repeated scanning of the body text, moves the process to step S615, and moves the process to step S1303 if it is within the range.
In step S1303, the address identification processing unit 141 determines whether or not the scanning position (scanning position symbol or character) is a quotation mark (exclusion symbol). If the scanning position is a quotation mark, the address specification processing unit 141 proceeds to step S1304, and if the scanning position is not a quotation mark, the address specification processing unit 141 proceeds to step S605. For example, the address specification processing unit 141 determines whether the scanning position is a quotation mark based on whether the scanning position is the beginning of a line and a quotation mark character (for example, “>”).

In steps S1304 and S1305, as in steps S612 and S613, the address specification processing unit 141 adds the contents of the address buffer to the address storage area and empties the address buffer when the address buffer is not empty.
In step S1306, the address specification processing unit 141 advances the scanning position to the end of the current line, and advances the process to step S610. That is, when there is a quotation mark (exclusion symbol), the address specification processing unit 141 excludes a line including the quotation mark from the scanning range.

Next, as a more specific example, the process of FIG. 17 will be described by taking the case of trying to send the e-mail shown in FIG. FIG. 18 is a third diagram illustrating an example of an electronic mail. For the electronic mail in FIG. 18, it is assumed that the sender does not attempt to send an electronic mail to the address “sato.kazuo@dekoboko.jp”. However, according to the first embodiment, the text character string 1404 (“Uneven Shoji Sato”) is determined to be the address, and thus is erroneously transmitted to the address “sato.kazuo@dekoboko.jp”.
In step S1301, the address specification processing unit 141 reads a value stored in advance in the external memory 211 as a scanning range. Here, the read value indicates four rows.

The address specification processing unit 141 specifies an address for the text string 1402 (“Δ □ Industrial Nakata”) as in the first embodiment.
Thereafter, the processing is continued, and the address specification processing unit 141 shifts the processing from step S604 to step S1302 because the scanning position becomes the text position 1403.
In step S1302, the address identification processing unit 141 interrupts the scanning process and moves the process to step S615 because the scanning position exceeds the value (four rows) read in step S1301.

  As a result, the body text string 1404 (“Uneven Shoji Sato”) is not determined to be an address, and in the subsequent processing, the information processing apparatus 100 warns that there is no address at the address “sato.kazuo@dekoboko.jp”. The

Next, a case where the electronic mail shown in FIG. 19 is to be transmitted will be described. FIG. 19 is a diagram (part 4) illustrating an example of an electronic mail. Note that it is assumed that the sender of the electronic mail in FIG. 19 does not send an electronic mail to the address “sato.kazuo@dekoboko.jp”. However, according to the first embodiment, the text character string 1504 (“Uneven Shoji Sato”) is determined to be the address, so that it is erroneously transmitted to the address “sato.kazuo@dekoboko.jp”.

In step S1301, the address specification processing unit 141 reads a value stored in advance in the external memory 211 as a scanning range. Here, the read value indicates four rows.
The address specification processing unit 141 specifies an address for the text string 1502 (“Δ □ Industrial Nakata”) as in the first embodiment.
Thereafter, the processing is continued, and the address specification processing unit 141 shifts the processing from step S604 to step S1302 because the scanning position becomes the text position 1503.

In step S1302, the address identification processing unit 141 moves the process to step S1303 because the scanning position does not exceed the value (four lines) read in step S1301.
In step S1303, the address specification processing unit 141 determines that the scanning position is a quotation mark, and moves the process to step S1304.
In step S1304, the address identification processing unit 141 proceeds to step S1306 because the address buffer is empty.

In step S1306, the address specification processing unit 141 advances the scanning position to the end of the line. The scanning position is located behind the text string 1504 (“Uneven Trading Sato”).
As a result, the text string 1504 (“Uneven Shoji Sato”) is not determined to be an address, and in the subsequent processing, the information processing apparatus 100 warns that there is no address at the address “sato.kazuo@dekoboko.jp”. The

  As described above, according to the above-described embodiment, it is possible to specify the scanning range of the text of the email to be targeted in advance, or to specify the scanning range of the text of the targeted email according to the destination address. it can.

FIG. 21 is a diagram (part 3) illustrating an example of an address book. The expansion of the address book is realized by automatically generating a notation in which the first character is written in parentheses for the attribute “name” and the attribute “department”.

In the present embodiment, the information processing apparatus 100 determines that the notation “(sum)” is an attribute “name”, and therefore can correctly specify the address even for the notation such as “Sato (wa)”. .
Further, the address book extension unit 145 automatically generates an extended connection order table as shown in FIG. 22 with respect to the connection order table shown in FIG. 7 of the first embodiment. The information processing apparatus 1 uses a connection order table as shown in FIG. 22 instead of the connection order table as shown in FIG. FIG. 22 is a diagram (part 2) illustrating an example of a connection order table defining attribute connection orders in the address buffer.
As described above, according to the present embodiment, when an e-mail transmission instruction is received, a character string related to the address attribute is detected from the body of the e-mail, the address (character string) is specified from the detected character string, and the e-mail The address information in which the address and the address (character string such as name) are associated is searched, the e-mail address corresponding to the specified address is specified, and the specified e-mail address is sent It is determined whether or not the instructed e-mail is set as a transmission destination, and when it is determined that the e-mail address is not set as the e-mail transmission destination, warning information is output. Thereby, omission of transmission of the e-mail can be prevented, and the e-mail can be transmitted to a destination (transmission destination) to be transmitted.
