Email wrong transmission preventing apparatus and method
First Claim
1. An email wrong transmission preventing apparatus that prevents wrong transmission of email, the apparatus comprising:
- an email storage unit that stores a planned outgoing email;
a transmission log storage unit that stores a transmission log including a sender, a destination, and a transmission date/time of a planned outgoing email transferred to a transmission server;
a user weight list generating unit that acquires the transmission log from the transmission log storage unit, uses an expression indicating a model in which values decline in accordance with tracking back in the transmission order from the latest in the process to calculate memory ratios of addresses of emails in the transmission log, and creates a user weight list recording values, which are obtained by compiling the calculated memory ratios for each destination, as weights of the destinations;
a user weight list storage unit that stores the user weight list;
an email receiving unit that acquires the planned outgoing email transmitted from a client and that holds the planned outgoing email in the email storage unit;
an address determination unit that refers to the user weight list, specifies the weight of the destination of the planned outgoing email, compares the specified weight of the destination with a predetermined threshold, and determines that the destination is not reliable if the weight is equal to or smaller than the threshold;
an address checking unit that outputs information related to an address check of the planned outgoing email and that receives an input of “
checked”
for the destination if the address determination unit determines that the destination is not reliable;
an email transmitting unit that transfers the planned outgoing email to the transmission server after the address checking unit receives the input of “
checked”
; and
a transmission log acquisition unit that stores the transmission log of the transferred planned outgoing email in the transmission log storage unit.

Abstract
An email wrong transmission preventing apparatus calculates memory ratios of addresses of emails in a transmission log by a model expression in which the memory ratios decline over time, compiles the memory ratios of the emails for each destination to set weights, and records the weights in a user weight list. When receiving a planned outgoing email, the apparatus compares the weight of the destination of the planned outgoing email obtained by referring to the user weight list with a predetermined threshold and determines that the destination is “reliable” only if the weight is over the threshold. If even one of the destinations of the planned outgoing email is not “reliable”, the apparatus causes a sender terminal to display an address check screen to prompt address checking. When “checked” is inputted, the apparatus transfers the planned outgoing email to an email transmission server.
