Abstract: Provided is a technology for performing flexible access control to permit decoding of secret information exclusively with a specific user in a case where secret splitting is hierarchically executed. There is provided an information processing apparatus including a control unit that generates, from a first key with which first data is decodable, a plurality of shares based on the first key in response to a first-key generation request, restores the first key from the shares based on the first key in response to a second-key generation request, encrypts, with the first key, a part of a plurality of shares based on a part or all of the first key as a second key with which second data is decodable, and generates a plurality of shares based on the second key.

Abstract: [Problem] It is desirable to provide a technology for performing the flexible access control to permit the decoding of secret information exclusively with a specific user in a case where secret splitting is hierarchially executed. [Solution] There is provided an information processing apparatus including a control unit that generates, from a first key with which first data is decodable, a plurality of shares based on the first key in response to a first-key generation request, restores the first key from the shares based on the first key in response to a second-key generation request, encrypts, with the first key, a part of a plurality of shares based on a part or all of the first key as a second key with which second data is decodable, and generates a plurality of shares based on the second key.

Abstract: In one example embodiment, a microscope control device a controller configured to store a plurality of images having different depth positions. In one example embodiment, the microscope control device divides the plurality of images into a plurality of sub-regions. In one example embodiment, the microscope control device, for each sub-region, generates in-focus position information which corresponds to a depth position.
