An information terminal of a user B who permits a user A to search the person B calculates a calculation result G(Pa′, Pb) by using information Pa′ related to the user A and information Pb of the user B, both Pa′ and Pb being stored in the information terminal of the user B and transmits to a server the calculation result G(Pa′, Pb). Further, the information terminal of the user B receives trust information expressing that Pb is authenticated and calculates a calculation result F(Pb) and transmits to the server. The information terminal of the user A calculates G(Pa, Pb′) and transmits it to the server. When the server receives G(Pa, Pb′) from the information terminal of the user A, the server searches G(Pa′, Pb) which matches G(Pa, Pb′) and the search result with F(Pb) to the information terminal of the user A. The information terminal of the user A calculates F(Pb′) and compares it with F(Pb) which is sent by the server.

A private communication network through which a plurality of member users communicate using the public switched telephone network (PSTN) is disclosed herein.

The private communication network includes network call manager having a telephone network interface for establishing a telephone connection with each of a plurality of telephone lines of the PSTN. Each of the plurality of telephone lines is associated with one of the plurality of member users. The network call manager further includes a switch matrix, coupled to the telephone network interface, for providing an information signal received from an active member user over a selected telephone line to the remaining non-active member users. A network call manager controller identifies the active member user the basis of push-to-talk (PTT) request signals received from the member users'telephones over the plurality of telephone lines. The telephone set of each member user will typically be capable of both standard telephone operation as well as of PTT operation over the private communication network. The security of the PTT private network may be enhanced by configuring each telephone set for encryption of all such reverse link transmissions, as well as for corresponding decryption of the forward link information from the active member user.

A method and system for file-system based caching can be used to improve efficiency and security at network sites. In one set of embodiments, the delivery of content and storing content component(s) formed during generation of the content may be performed by different software components. Content that changes at a relatively high frequency or is likely to be regenerated between requests may not have some or all of its corresponding files cached. Additionally, extra white space may be removed before storing to reduce the file size. File mapping may be performed to ensure that a directory within the cache will have an optimal number of files. Security at the network site may be increased by using an internally generated filename that is not used or seen by the client computer. Many variations may be used is achieving any one or more of the advantages described herein.
