Latest Patents

Okamoto's latest patents include an outgoing email check system, a check data providing apparatus, a check data inspecting apparatus, and an outgoing email check method. These innovations allow for the inspection of whether a security check of a planned outgoing email is completed. The outgoing email check system stores check information distributed from a check information management apparatus. It appends check data generated based on this information to the header of a checked planned outgoing email and transmits the email to an email transmitting apparatus. The check data inspecting apparatus inspects the check data extracted from the planned outgoing email based on the check information. It determines whether the transmission is permitted or rejected based on the match of check data with the check information. The email transmitting apparatus executes the transmission process only for emails that are permitted.

Another significant invention is the email wrong transmission preventing apparatus and method. This apparatus calculates memory ratios of email addresses in a transmission log, compiles these ratios for each destination, and sets weights recorded in a user weight list. When a planned outgoing email is received, the apparatus compares the weight of the destination with a predetermined threshold. If the weight exceeds the threshold, the destination is deemed 'reliable'. If not, the apparatus prompts the sender to check the address before proceeding with the transmission.
