Communication control apparatus, communication control method, and non-transitory computer readable medium for controlling transmission of a message that includes an attached file

A communication control method of controlling transmission of a message including an attached file, when the message is transmitted from an information processing apparatus to one or more destinations via a network, comprising;

• with a computer,
• determining whether the message to be transmitted from the information processing apparatus include at least one attached file;
• acquiring approval of transmission of said at least one attached file from an approver, when the message to be transmitted includes said at least one attached file;
• transmitting the message including said at least one attached file to said one or more destinations, on condition that approval of transmission of said at least one attached file has been received from the approver;
• storing, in a level storage, confidential levels indicating disclosure levels for confidential information for predetermined destinations;
• discriminating each of the one or more destinations as to whether the one or more destinations are at a confidential level requiring approver's approval when the at least one attached file is transmitted, based on the confidential levels stored in the level storage, when the message to be transmitted includes said at least one attached file, wherein the method includes transmitting said at least one attached file for which approval has been acquired from the approver with the approval section at least to the one or more discriminated destinations as a destination being at the confidential level requiring approval;
• storing, in a rule storage, at least a transmission rule indicating whether approval by the approver is required for transmission of the at least one attached file;
• decide whether approval by the approver is required, based on the transmission rule stored in the rule storage, for said at least one attached file to be transmitted to the one or more discriminated destinations as the destination being at the confidential level requiring approval;
• and
• transmitting the at least one decided attached file as an attached file requiring approval by the approver, on condition that approval has been acquired,
• wherein
• the rule storage stores the transmission rule in accordance with confidential properties of the at least one attached file, the confidential properties being values specified from file property information and enabling specification of data contents of the at least one attached file without determining the data contents of the at least one attached file included in the message, items “approval is required”, “encryption is required”, and “transmission is impossible” being provided in association with the confidential properties with which the at least one attached file may be a confidential file with disclosure restriction, the items being provided for each of the at least one attached file, and
• the computer decides whether the at least one attached file matches any of the confidential properties in the transmission rule, for each of said at least one attached file to be transmitted to the one or more destinations, and decides that the at least one attached file requires approval by the approver when the attached file matches any of the confidential properties.

A non-transitory computer readable medium storing a computer program that causes a processor included in a communication control apparatus, to:

• determine whether a message to be transmitted from an information processing apparatus include at least one attached file;
• acquire approval of transmission of said at least one attached file from an approver, when the message to be transmitted includes said at least one attached file;
• and
• transmit the message including said at least one attached file to said one or more destinations, on condition that approval of transmission of said at least one attached file has been received from the approver;
• store, in a level storage, confidential levels indicating disclosure levels for confidential information for predetermined destinations;
• discriminate each of the one or more destinations as to whether the one or more destinations are at a confidential level requiring approver's approval when the at least one attached file is transmitted, based on the confidential levels stored in the level storage, when the message to be transmitted includes said at least one attached file, wherein the method includes transmitting said at least one attached file for which approval has been acquired from the approver with the approval section at least to the one or more discriminated destinations as a destination being at the confidential level requiring approval;
• store, in a rule storage, at least a transmission rule indicating whether approval by the approver is required for transmission of the at least one attached file;
• decide whether approval by the approver is required, based on the transmission rule stored in the rule storage, for said at least one attached file to be transmitted to the one or more discriminated destinations as the destination being at the confidential level requiring approval;
• and
• transmit the at least one decided attached file as an attached file requiring approval by the approver, on condition that approval has been acquired,
• wherein
• the rule storage stores the transmission rule in accordance with confidential properties of the at least one attached file, the confidential properties being values specified from file property information and enabling specification of data contents of the at least one attached file without determining the data contents of the at least one attached file included in the message, items “approval is required”, “encryption is required”, and “transmission is impossible” being provided in association with the confidential properties with which the at least one attached file may be a confidential file with disclosure restriction, the items being provided for each of the at least one attached file, and
• the processor decides whether the at least one attached file matches any of the confidential properties in the transmission rule, for each of said at least one attached file to be transmitted to the one or more destinations, and decides that the at least one attached file requires approval by the approver when the attached file matches any of the confidential properties.
