An information processing terminal, a status notifying system and a status notifying method wherein when a status of an information processing terminal is notified to a server, both the privacy and the security can be maintained at the same time. An information processing terminal (10) comprises a publication determining part (1001) that determines the other end of possible notifying communication for each of entries; a log concealing part (1002) that conceals the entries; a multiple log determining part (1003) that instructs hash updating for a plurality of other ends of notifying communication; a log constituting part (1004) that constitutes a log for the other end of notifying communication and causes a signature to be written; a verification requesting part (1005) that requests a verification; a policy storing means (1006) that stores a policy used in determining the other end of possible notifying communication; and a log storing means (1007) that stores the entries. The information processing terminal (10) instructs an accumulation of entries, in which processings, such as suitable concealment processing, have been done for each of the other ends of notifying communication, using hashes.
