The controller manages to store the biometric data of each user in the same storage area using the unique tag number. ## Claims ### Claim 1 A shared vehicle management server of a vehicle sharing system configured to allow a plurality of users to share and use a vehicle, the shared vehicle management server comprising: an interface configured to receive biometric data from the plurality of users; a storage device configured to store the biometric data received through the interface; and a controller configured to assign a unique tag number to each of the plurality of users and to manage the biometric data of each of the plurality of users using the unique tag number, wherein the controller is configured to store the biometric data of each of the plurality of users in a same storage area of the storage device using the unique tag number. ### Claim 2 (depends on 1) The shared vehicle management server of claim 1, wherein the controller is configured to identify whether newly input biometric data is biometric data of a registered user. ### Claim 3 (depends on 2) The shared vehicle management server of claim 2, wherein the controller is configured to determine, when the newly input biometric data is the biometric data of the registered user, whether a tag number generated from the corresponding biometric data is present. ### Claim 4 (depends on 3) The shared vehicle management server of claim 3, wherein the controller is configured to perform a write operation or a read operation on a storage area of the storage device, to which a tag number is assigned, when the tag number generated from the corresponding biometric data is present. ### Claim 5 (depends on 4) The shared vehicle management server of claim 4, wherein the storage area is one or more memory blocks. ### Claim 6 (depends on 3) The shared vehicle management server of claim 3, wherein the controller is configured to assign a tag number and a storage area, and perform a write operation or a read operation on the assigned storage area when the tag number generated from the corresponding biometric data is not present. ### Claim 7 (depends on 1) The shared vehicle management server of claim 1, wherein the controller is configured to perform a migration operation using a same tag number when the biometric data of each of the plurality of users stored in the same storage area becomes invalid and new valid data is input. ### Claim 8 (depends on 7) The shared vehicle management server of claim 7, wherein the controller is configured to store a tag number and biometric data in another storage area through the migration operation. ### Claim 9 (depends on 1) The shared vehicle management server of claim 1, wherein the storage device comprises: a basic information storage area configured to store the biometric data and the tag number; a user information storage area configured to store data identification information and user data information; and a temporary information storage area used to perform a migration operation. ### Claim 10 (depends on 1) The shared vehicle management server of claim 1, wherein the storage device is a flash storage device. ### Claim 11 A method of operating a shared vehicle management server, the method comprising: receiving biometric data from a plurality of users; storing the received biometric data in a flash storage device; and assigning a unique tag number to each of the plurality of users and managing the assigned unique tag number, wherein the biometric data of each of the plurality of users is stored in a same storage area using the unique tag number. ### Claim 12 (depends on 11) The method of claim 11, further comprising: identifying whether newly input biometric data is biometric data of a registered user. ### Claim 13 (depends on 12) The method of claim 12, further comprising: determining, when the newly input biometric data is the biometric data of the registered user, whether a tag number generated from a corresponding biometric data is present. ### Claim 14 (depends on 13) The method of claim 13, further comprising: performing a write operation or a read operation on a storage area, to which a tag number is assigned, when the tag number generated from the corresponding biometric data is present; and assigning a tag number and a storage area when the tag number generated from the corresponding biometric data is not present, and performing the write operation or the read operation on the assigned storage area. ### Claim 15 (depends on 11) The method of claim 11, further comprising: performing a migration operation using a same tag number when the biometric data of each of the plurality of users stored in the same storage area becomes invalid and new valid data is input. ### Claim 16 A user data management server configured to use biometric information to provide vehicle sharing service, the user data management server comprising: an interface configured to receive biometric data and user data from a user; a storage device configured to store the biometric data, a tag number, and the user data received from the interface; and a controller configured to manage the user data using the biometric data and the tag number of the storage device, wherein the storage device comprises: a basic information storage area configured to store the biometric data and the tag number; a user information storage area configured to store data identification information and user data information; and a temporary information storage area used to perform a migration operation, wherein the user information storage area comprises one or more blocks, the one or more blocks comprise one or more pages, and a write operation and a read operation are performed in units of a page and an erase operation is performed in units of a block. ### Claim 17 (depends on 16) The user data management server of claim 16, wherein the tag number is a single number assigned to a single piece of biometric data. ### Claim 18 (depends on 17) The user data management server of claim 17, wherein the tag number is an address value of a block or a page in which the data identification information and the user data information are stored. ### Claim 19 (depends on 18) The user data management server of claim 18, wherein the user information storage area is configured to store the data identification information on a single piece of biometric data and the user data information in a single block or a single page. ### Claim 20 (depends on 19) The user data management server of claim 19, wherein the controller is configured to perform a read operation once on a single piece of biometric data to read all user data.
