Communication system and method, information processing terminal and method, and information processing device and method
First Claim
1. An information processing apparatus comprising;
- a storing unit for storing first identification information, wherein the first identification information includes a first number;
an acquiring unit for acquiring second identification information from another information processing apparatus by short distance wireless communication, wherein the second identification information includes a second number; and
an establishing unit for establishing wireless communication with the other information processing apparatus,wherein the establishing unit establishes wireless communication by sending a request to the other information processing apparatus when the first identification information is determined to be greater than the second identification information based on a comparison of the first and second numbers, andwherein the establishing unit establishes a wireless communication based on a request from the other information processing apparatus when the second identification information is determined to be greater than the first identification information based on the comparison of the first and second numbers.

Abstract
The present invention relates to a communication system and method, an information processing terminal and method, and an information processing device and method which enable simple and secure restricted access. When a PDA 11 is brought close, a reader 2 of a personal computer 1 reads a device ID form an IC tag 12. The personal computer 1 registers device IDs on a connection permission list, and permits only devices registered on the list to connect. When being instructed to perform accessing, the PDA 11 controls a communication unit to access the personal computer 1 and to transmits its device ID. The personal computer 1 determines whether or not the transmitted ID is registered on the connection permission list, and permits the connection when determining that the ID is registered. The present invention can be applied to various information processing devices such as a personal computer and a PDA.
