Information processing apparatus, information processing method, and information processing program

An information processing apparatus comprising:

• at least one memory operable to store program instructions;
• at least one processor operable to read said program instructions and operate according to said program instructions, said program instructions including:
• authentication information obtaining instructions configured to cause at least one of said at least one processors to obtain authentication information including a plurality of codes and conforming to a predetermined requirement of complexity;
• cost obtaining instructions configured to cause at least one of said at least one processors to obtain a cost of inputting each of the plurality of codes;
• calculating instructions configured to cause at least one of said at least one processors to calculate an input cost of the authentication information based on the obtained costs;
• and
• determining instructions configured to cause at least one of said at least one processors to determine propriety of the authentication information based on the input cost.

An information processing method executed by a computer, comprising:

• obtaining authentication information including a plurality of codes and conforming to a predetermined requirement of complexity;
• obtaining a cost of inputting each of the plurality of codes;
• calculating an input cost of the authentication information based on the obtained costs;
• and
• determining propriety of the authentication information based on the input cost.

A non-transitory computer readable medium storing thereon an information processing program, the information processing program causing a computer to:

• obtain authentication information including a plurality of codes and conforming to a predetermined requirement of complexity;
• obtain a cost of inputting each of the plurality of codes;
• calculate an input cost of the authentication information based on the obtained costs;
• and
• determine propriety of the authentication information based on the input cost.
