Information processing apparatus, method, and program

An information processing apparatus, comprising:

• at least one memory;
• and
• at least one processor, wherein
• the at least one processor executes
• acquiring an estimated value of a first attribute by inputting body information in which a value of the first attribute is missing to at least one trained model,
• acquiring an estimated value of a second attribute by inputting body information in which a value of the second attribute is missing to the at least one trained model, the second attribute being different from the first attribute, and
• deleting the body information in which the value of the first attribute is missing, the estimated value of the first attribute, the body information in which the value of the second attribute is missing, and the estimated value of the second attribute from the information processing apparatus.

A terminal, comprising:

• at least one memory;
• and
• at least one processor, wherein
• the at least one processor executes
• transmitting body information in which a value of a first attribute is missing to at least one information processing apparatus,
• receiving an estimated value of the first attribute from the at least one information processing apparatus,
• transmitting body information in which a value of a second attribute is missing to the at least one information processing apparatus, the second attribute being different from the first attribute, and
• receiving an estimated value of the second attribute from the at least one information processing apparatus.

A terminal, comprising:
