Abstract: A personal information anonymization method is disclosed. Each of a plurality of data including personal information is classified into any one of a plurality of groups based on a degree of commonality of the personal information. An anonymization process, that standardizes the personal information of each of data belonging to each of the groups, is performed for each of the groups. A total number of the data belonging to each of the groups is calculated for each of the groups. The plurality of the groups are classified based on the total number of the sets of the data. A classification result is output.

Abstract: A mail monitoring system comprises a mail communications apparatus and a control server that controls a log relating to operation of the apparatus. The apparatus includes a detector that detects transmission of an e-mail, a log generation unit that determines whether to generate a transmission log based on a set policy, and generates the transmission log, a mail creating unit that determines whether to store mail information based on the set policy, and generates the mail information, and a transmitter that transmits the mail information and the transmission log to the server, and transmits the e-mail to a mail server designated as a transmission destination of the e-mail. The server includes a receiver that receives the transmission log and the mail information and a storage unit that stores therein the transmission log and the mail information when the receiver receives the transmission log and the mail information.

Abstract: An access filtering device includes a receiving unit that receives a URL of a prohibited site or a prohibited page; an executing unit that accesses the page by using the URL; an acquiring unit that acquires page information corresponding to the URL; a prohibited site list that includes character strings of prohibited sites and prohibited pages; a determining unit that determines whether the URL is a character string of a prohibited site or a prohibited page; a display control unit that, when the URL is a character string of a prohibited site or a prohibited page, displays the page in a decreased page-readability state, i.e., in a transparent state.

Abstract: A terminal apparatus generates a hash value from a sequence number based on a predetermined hash algorithm, and creates identification information from an IP address and/or a MAC address and the generated hash value based on a predetermined creation algorithm. Moreover, at the time of processing for shutdown or reboot, the terminal apparatus stores the current recording device information into a hard disk, and when booted next time, determines whether or not the current recording device information and the recording device information stored in the hard disk match with each other. Further, when booted, the terminal apparatus requests a response from another terminal apparatus in the network segment, and when there is not a response from another terminal apparatus, creates management information of terminal apparatuses including itself having been booted in the network segment.

Abstract: An electronic security information management method and recording medium using an IC card to prevent data leaks by a dishonest third party who is carrying, a secret data recorded on an information processing apparatus, such as a computer, integrated circuit card, floppy disk, or other recording medium to the outside of an organization. The electronic security information management method and recording medium can deter the use of the data copied to a recording medium by the dishonest third party and will also record and allow for later inspection the processes used for copying the data to the recording medium.
