Abstract
An information management method according to an aspect of the present disclosure includes disclosing, by a computer, a second parameter obtained by irreversibly converting a first parameter and disclosing, by the computer, the first parameter simultaneously with disclosing the second parameter or after disclosing the second parameter.
Claims7
An information management method comprising:
- acquiring a first parameter from an optical device that includes identification information that identifies the optical device;
- generating a second parameter by irreversibly converting the first parameter;
- causing the optical device to display an image that includes a mark that represents the second parameter;
- generating a token that includes the first parameter and the second parameter;
- and
- registering the token in order to disclose the first parameter and the second parameter in the token, wherein disclosure of the first parameter in the token enables an outsider to specify the second parameter using the mark that represents the second parameter.

A display apparatus comprising:
- an optical device;
- and
- a controller programmed to execute
- acquiring a first parameter from the optical device that includes identification information that identifies the optical device;
- generating a second parameter by irreversibly converting the first parameter;
- causing the optical device to display an image that includes a mark that represents the second parameter;
- generating a token that includes the first parameter and the second parameter;
- and
- registering the token in order to disclose the first parameter and the second parameter in the token, wherein disclosure of the first parameter in the token enables an outsider to specify the second parameter using the mark that represents the second parameter.

A non-transitory computer-readable storage medium storing a program, the program causing a computer to execute:
- acquiring a first parameter from an optical device that includes identification information that identifies the optical device;
- generating a second parameter by irreversibly converting the first parameter;
- causing the optical device to display an image that includes a mark that represents the second parameter;
- generating a token that includes the first parameter and the second parameter;
- and
- registering the token in order to disclose the first parameter and the second parameter in the token, wherein disclosure of the first parameter in the token enables an outsider to specify the second parameter using the mark that represents the second parameter.
