Abstract
A storage device of the disclosure includes: a storage section that stores data; a communication section that performs wireless communication with one or a plurality of electronic apparatuses; an interface section that performs exchange of the data with a host apparatus; and a control section that determines a distance to each of the electronic apparatuses through the wireless communication, and controls access to the storage section by the host apparatus, on the basis of the distance and whether the host apparatus is accessing the storage section.
Claims19
A storage device comprising:
- a storage section that stores data;
- a communication section that performs wireless communication with one or a plurality of electronic apparatuses;
- an interface section that performs exchange of the data with a host apparatus;
- and
- a control section that determines a distance to each of the electronic apparatuses through the wireless communication, and controls access to the storage section by the host apparatus, on a basis of the distance and whether the host apparatus is accessing the storage section.
The storage device according to claim l wherein the control section confirms consistency of a file system of the storage section, and determines that the host apparatus is not accessing the storage section in a case where the consistency is provided.
A reader writer comprising:
- a communication section that performs wireless communication with one or a plurality of electronic apparatuses;
- an interface section that performs exchange of data with a host apparatus;
- and
- a control section that determines a distance to each of the electronic apparatuses through the wireless communication, and controls access to a storage section by the host apparatus, on a basis of the distance and whether the host apparatus is accessing the storage section, the storage section storing the data.
An access control system comprising:
- one or a plurality of electronic apparatuses;
- a host apparatus;
- and
- a storage device, wherein
- the storage device includes
- a storage section that stores data,
- a communication section that performs wireless communication with the one or the plurality of electronic apparatuses,
- an interface section that performs exchange of the data with the host apparatus, and
- a control section that determines a distance to each of the electronic apparatuses through the wireless communication, and controls access to the storage section by the host apparatus, on a basis of the distance and whether the host apparatus is accessing the storage section.
An access control method comprising:
- performing wireless communication with one or a plurality of electronic apparatuses to thereby determine a distance to each of the electronic apparatuses;
- and
- controlling access to a storage section by a host apparatus, on a basis of the distance and whether the host apparatus is accessing the storage section.
