Information processing apparatus, illegal picture-taking operation preventing method, and illegal picture-taking operation prevention program

An information processing apparatus including a picture-taking function, capable of taking a picture of an object on which a wireless IC tag is loaded, comprising:

• a picture-taking object check signal generating unit generating, when the picture-taking function is activated, a picture-taking object check signal checking whether the wireless IC tag is loaded on the picture-taking object;
• a signal transmitting/receiving unit transmitting a picture-taking object check signal and receiving a response signal from the wireless IC tag;
• a response time measuring unit measuring a response time between transmission of the picture-taking object check signal and reception of the response signal;
• a distance calculating unit calculating a distance between the wireless IC tag and the information processing apparatus, on the basis of the response time;
• and
• a control unit comparing the distance calculated with the distance calculating unit with a picture-taking action limiting distance of the wireless IC tag, and controllably permitting the picture-taking function when the distance is larger than the picture-taking action limiting distance and controllably inhibiting the picture-taking function when the distance is smaller than the picture-taking action limiting distance.

An illegal picture-taking preventing method controlling picture-taking of an object on which a wireless IC tag is loaded, comprising:

• activating a picture-taking function to take a picture of said object;
• generating a picture-taking object check signal checking whether the wireless IC tag is loaded on the picture-taking object;
• transmitting the picture-taking object check signal;
• and
• controlling the picture-taking function on the basis of a received response signal.

An illegal picture-taking preventing method controlling picture-taking of an object on which a wireless IC tag is loaded, comprising:

• activating a picture-taking function for taking a picture of the object;
• generating a picture-taking object check signal checking whether the wireless IC tag is loaded on the picture-taking object;
• transmitting the picture-taking object check signal;
• measuring a response time between transmission of the picture-taking object check signal and reception of the response signal;
• calculating a distance between the wireless IC tag and the information processing apparatus on the basis of the response time;
• and
• comparing the distance with a picture-taking limiting distance of the wireless IC tag and controllably permitting the picture-taking function when the distance is larger than the picture-taking limiting distance, and controllably inhibiting the picture-taking function when the distance is smaller than the picture-taking limiting distance.

A computer readable storage medium storing an illegal picture-taking preventing program causing a computer to control picture-taking of an object on which a wireless IC tag is loaded, by:

• activating a picture-taking function to take a picture of the object;
• generating a picture-taking object check signal to check whether the wireless IC tag is loaded on the picture-taking object;
• transmitting the picture-taking object check signal;
• and
• controlling the picture-taking function on the basis of a received response signal.
