Information processing apparatus, method, and non-transitory computer-readable storage medium to encrypt search value for searching job log using first key and server performs search process

A method for an information processing system including an information processing apparatus, an image processing apparatus, and a server, the method comprising:

• executing, by the image processing apparatus, encryption processing on a job log using a first key;
• registering, by the image processing apparatus, a plurality of job logs on which the encryption processing is executed, in the server;
• encrypting, by the information processing apparatus, a value used for searching for the job log using another first key being a duplicate of the first key;
• transmitting, by the information processing apparatus, a search request including the encrypted value to the server via the network;
• executing, by the server, search processing by searching for data corresponding to the encrypted value included in the search request without decrypting the plurality of job logs registered and managed by the image processing apparatus;
• transmitting, by the server, a response indicating a result of the search processing to the information processing apparatus;
• acquiring, by the information processing apparatus, the encrypted job log based on the response from the server;
• and
• executing, by the information processing apparatus, decryption processing for decrypting the encrypted job log.

A method for an information processing apparatus that communicates with a server via a network, the server configured to manage a plurality of job logs on which encryption processing is executed by an image processing apparatus using a first key, the method comprising:

• encrypting a value used for searching for a job log using another first key being a duplicate of the first key;
• transmitting a search request including the encrypted value to the server via the network;
• acquiring an encrypted job log based on a response from the server;
• and
• executing decryption processing for decrypting the encrypted job log,
• wherein the server executes search processing using the encrypted value included in the search request without decrypting the plurality of job logs managed.

A non-transitory computer-readable storage medium having computer executable instructions stored thereon, wherein execution of the instructions by a computer causes the computer, as an information processing apparatus that communicates with a server via a network, the server configured to manage a plurality of job logs on which encryption processing is executed by an image processing apparatus using a first key, to:

• encrypt a value used for searching for a job log using another first key being a duplicate of the first key;
• transmit a search request including the encrypted value to the server via the network;
• acquire an encrypted job log based on a response from the server;
• and
• execute decryption processing for decrypting the encrypted job log,
• wherein the server executes search processing using the encrypted value included in the search request without decrypting the plurality of job logs managed.
