Abstract

A sharing system includes a sharing device arranged in a shared subject and a valet key that is allowed to operate the shared subject. The sharing system further includes a portable terminal that obtains key information required to use the shared subject and is allowed to operate the shared subject when the key information is authenticated through communication with the sharing device. The sharing system further includes a privilege granting unit that grants privilege to operate the shared subject from the portable terminal to the valet key, and a restriction imposing unit that imposes a restriction on use of the portable terminal when the operation privilege for the shared subject is granted from the portable terminal to the valet key.
