Abstract: A communication terminal includes: an update section that obtains software via a communication network from a predetermined provider so as to update the software; and a failure monitor section that monitors whether there is a failure to interfere with an update of the software by the update section. The communication terminal further includes an update record section that records, if there is the failure and the update becomes an incomplete update on an occasion of the update by the update section, the presence of the incomplete update; and an update prompting section that prompts, if a monitor result by the failure monitor section changes from that there is a failure to that there is no failure, performing by the update section the update whose presence is recorded by the update record section.

Abstract: Disclosed is a FAX communication system for improving security and reliability of FAX communication. A FAX receiver receives FAX data and transmission source information. A transmission destination designation information acquisition section obtains transmission destination designation information during indirect communication of FAX data. A transmission destination number extraction section extracts stored and managed transmission destination numbers using the obtained information. An encryption processor extracts stored and managed serial numbers using the obtained information and encrypts identification data containing at least one of the transmission source information and serial number related to FAX data for transmission to generate encrypted data. An encrypted data attaching section attaches the encrypted data to FAX data for transmission to generate FAX data with encrypted data. A FAX transmitter transmits the FAX data with encrypted data to the transmission destination number.

Abstract: An information input method inputs certain information and probability information having uncertainty. The information input method displays a plurality of candidates with respect to the probability information that is input, and selects and fixes one of the plurality of displayed candidates in response to the certain information that is input.
