System and method for controlling access to subject data using location data associated with the subject data and a requesting device

A data processing method of controlling a data access operation of a data processing apparatus, comprising:

• a first obtain step of obtaining first location data which indicates a current location of the data processing apparatus;
• a storing step of storing, in a storing means, a plurality of subject data, wherein respective second location data is added to each of the plurality of subject data indicating an accessible location of the respective subject data;
• a second obtain step of obtaining the respective second location data corresponding to a desired one of the subject data to be accessed from the storing means;
• and
• a determining step of determining whether or not an access to the desired subject data is to be permitted in accordance with the first location data and the respective second location data.

A data processing system where a second data processing apparatus provides data in response to a data request sent by a first data processing apparatus, comprising:

• first obtain means for obtaining first location data in accordance with a current location of said first data processing apparatus;
• storing means for storing a plurality of subject data, wherein respective second location data is added to each of the plurality of subject data indicating an accessible location of the respective subject data;
• transmission means for transmitting the first location data to said second data processing apparatus along with an access request for a desired one of the subject data;
• second obtain means for obtaining the respective second location data corresponding to the desired subject data to be accessed from said storing means;
• and
• determination means for receiving the access request transmitted by said transmission means, and determining whether or not an access to the desired subject data is to be permitted for said first data processing apparatus in accordance with the first location data and the respective second location data.

A computer readable memory which stores program codes for controlling a data access operation of a data processing apparatus, comprising:

• program codes for a first obtain step of obtaining first location data which indicates a current location of the data processing apparatus;
• program codes for a storing step of storing, in a storing means, a plurality of subject data, wherein respective second location data is added to each of the plurality of subject data indicating an accessible location of the respective subject data;
• program codes for a second obtain step of obtaining the respective second location data corresponding to a desired one of the subject data to be accessed from the storing means;
• and
• program codes for a determining step of determining whether or not an access to the desired subject data is to be permitted in accordance with the first location data and the respective second location data.
