Communication device, communication method, communication system and service issuing method

A communication system comprising:

• a communication device including:
• a communication unit for transmitting and receiving signals with a service issuing terminal,
• a recording unit recorded with data, and also recorded with a pattern in which information specifies an access attribute indicating a permission about a readout process and a write process, and
• a control unit for, when receiving information specifying a region of the data from the service issuing terminal via the communication unit, recording the received information specifying the region of the data in the recording unit to determine the access attribute information corresponding to the specified region of the data;
• and
• a service issuing terminal including:
• a communication unit for transmitting and receiving signals with the communication device, and
• a processing unit for transmitting the information specifying the region of the data recorded in the recording unit of the communication device via the communication unit.

A service issuing method by a communication system comprising a communication device including a communication unit for transmitting and receiving signals with a service issuing terminal, and a recording unit recorded with data, and also recorded with a pattern in which information specifies an access attribute indicating a permission about a readout process and a write process, and the service issuing terminal including a communication unit for transmitting and receiving signals with the communication device, and a processing unit, the method comprising:

• transmitting, from the service issuing terminal, the information specifying a region of the data recorded in the recording unit of the communication device via the communication unit;
• and
• receiving, at the communication device, the information specifying the region of the data from the service issuing terminal via the communication unit;
• and
• recording the received information specifying the region of the data to determine the access attribute information corresponding to the specified region of data.

A communication method comprising:

• transmitting signals from a communication device to a service issuing terminal;
• receiving signals at the communication device from the service issuing terminal, wherein the communication device includes a recording unit recorded with data, and also recorded with a pattern in which information specifies an access attribute indicating a permission about a readout process and a write process;
• and
• when receiving information specifying a region of the data from the service issuing terminal, recording the received information specifying the region of the data in the recording unit to determine the access attribute information corresponding to the specified region of the data.
