Abstract: PROBLEM TO BE SOLVED: To more efficiently sort the private data held by each holder than in the prior art without being known by other holders. SOLUTION: The system sorts a plurality of private data (PD) a plurality of parties hold every kind. Each of the plurality of parties has an encrypt key commutable about the order in a multiple encryption. At every kind of already sorted PD, the system selects typical parties P1, P3 of parties holding the kind of PD, exchanges encrypted data of each party's PD between P1, P3 and a target party P5, encrypts each encrypted data obtained by P5 with an encrypt key of P5 to obtain data 1, further encrypts the encrypted data obtained by P1, P3 to obtain data 2 using encrypt keys of P1, P3, and decides that P1, P3 and P5 have the same kind of PD if the data 1 of P1, P3 agree with the data 2.

Abstract: PROBLEM TO BE SOLVED: To provide a selecting device, a selecting method, a program and a recording medium which solve the problem that it is difficult to appropriately select only desired data when there is a large amount of electronized data even though various data are electronized and used in accordance with the advancement and popularization of computers and can efficiently obtain a set related strongly to a predetermined reference element among a plurality of elements stored in a database or the like.
SOLUTION: This selecting device 10 for selecting an adjacent element set whose strength of a relation to the predetermined reference element satisfies a predetermined condition among the plurality of elements is provided with an adjacent element set candidate selecting part 110 for selecting a set of elements whose relation to the reference element is determined to be stronger among the plurality of elements as each of a plurality of adjacent element set candidates being a plurality of candidates in which the adjacent element sets are different from one another, and an adjacent element set selecting part 130 for selecting a set of elements whose relational strength to the reference element satisfies the predetermined condition as an adjacent element set in a sum of sets of the plurality of adjacent element set candidates.

Abstract: PROBLEM TO BE SOLVED: To provide a mail transmission/reception method and a mail transmission/reception system provided with an affinity to a present mail system and capable of specifying the leakage origin of a mail address. SOLUTION: The mail address configuration method comprises: a stage of transmitting the identifier of a receiver and the identifier of a transmitter to the mail server of the receiver; a stage of having the mail server calculate a value for which the identifier of the receiver, the identifier of the transmitter and a nonce issued by the mail server are ciphered with a secret key that only the mail server knows and transmit it to the receiver; and a stage of imparting the domain name of the receiver to the ciphered value and configuring the mail address (LD address) for sending mail to the receiver by the transmitter. Also, the mail transmission method comprises a stage of transmitting the mail address configured by the mail address configuration method to the transmitter. COPYRIGHT: (C)2006,JPO&NCIPI
