Information processing apparatus, information processing method, and recording medium

A non-transitory computer-readable recording medium storing stores computer-readable instructions that, when executed by a computer, cause the computer to perform a method comprising:

• creating an encryption key on a basis of a first type key stored in advance in an imaging apparatus, a second type key different from the first type key, and a third type key that is different from the first type key and the second type key and is a key multiplied with the second type key to create a combination key stored in the imaging apparatus, or is a key stored in the imaging apparatus together with the second type key, as an encryption key used by the imaging apparatus for encryption of artificial intelligence (AI) software including at least software of an artificial intelligence model;
• performing, by the imaging apparatus, image recognition processing using the artificial intelligence model on a captured image obtained by capturing an image of a subject;
• and
• creating, in response to specification of a key derived from new information different from original information as the third type key, a new encryption key based on the third type key derived from the new information, the first type key, and the second type key on a basis of the new information, the new information including new key-generation information and the original information being original key-generation information.
