Abstract

A portable device and an information management method are provided whereby personal information can be safely shared between two systems. Each entry of telephone directory information includes callee identification information identifying a callee to be called by mobile phone function and is readable from and updatable by an information processor. Use restriction information shows availability of each telephone directory information entry and includes read permission information indicating whether each telephone directory information entry can be read out or not. When a request to read out an entry of the telephone directory information is received from another information processor, a use restriction processor looks up the use restriction information corresponding to the requested entry of the telephone directory information and, if readout of the requested entry is permitted, permits the requested entry of the telephone directory information to be read out and provided to the information processor.
