The user terminal 32 may receive a result of performing a search in an arbitrary node 51 through the dApp 42 for the user. The user terminal 32 displays the received search result to the user.

The user may select the shared resource 10 from the list of shared resources 10 provided as a search result and request to acquire the right to use the shared resource 10 . The user terminal 32 may request the smart contract 41a for the manager of the blockchain network 50 to obtain the right to use the shared resource 10 selected by the user through the dApp 42 for the user.

The manager smart contract 41a determines whether the shared resource 10 is available or not, upon receiving a request for obtaining the right to use the shared resource 10 received from the dApp 42 for the user. Availability of the shared resource 10 may be determined based on conditions included in the request for obtaining the right to use the shared resource 10 . It is possible to determine whether there is another user who has already been reserved at the time requested by the user, and whether the user is a person who is not entitled to acquire the right to use because the user is registered in the blacklist. The manager smart contract 41a records in the block chain 60 that when the requested shared resource 10 is available, it grants the use right to the user terminal 32 that has requested the use right. That is, the manager smart contract 41a shares the content that the user terminal 32 has the right to use at the requested time to the block chain network 50, and the block chain network 50 through verification and consensus It stores in block 61 that the user has been granted the right to use. The manager smart contract 41a may provide that the use right is granted to the user terminal 32 through the user dApp 42 .

When the user terminal 32 acquires the use right, the user may unlock the composite IoT device 20 through the user terminal 32 and start using the shared resource 10 . The use start step (S30) is a step in which the user terminal 32 requests the lock-opening of the composite IoT device 20 based on the usage right to the blockchain network 50 through the dApp 42 for the user, the composite IoT device (20) determining whether the user terminal 32 is located within a predetermined distance, when the composite IoT device 20 and the user terminal 32 are located within a predetermined distance, the composite IoT device 20 and the user terminal ( 32) each requesting execution of a one-time authentication protocol from the blockchain network 50, the blockchain network 50 generates a one-time key according to the one-time authentication protocol to generate a one-time key for the composite IoT device 20 and the user transmitting each to the terminal 32, and when the one-time key received by the composite IoT device 20 matches the one-time key received from the user terminal 32, the right to use the user terminal 32 Determining that there is a lock may include the step of opening the lock.

The user may request a lock open from the composite IoT device 20 coupled to the shared resource 10 that has obtained the right to use it through the user terminal 32 . The user terminal 32 may request unlocking of the lock from the composite IoT device 20 directly or through a dApp or blockchain network 50 .

Upon receiving the lock open request, the composite IoT device 20 may determine whether the user terminal 32 is located within a predetermined distance. If the user terminal 32 opens the lock module 21 based on the use right while the user terminal 32 is not near the shared resource 10, there is a risk that others without the use right will use the shared resource 10, It is determined whether the user is located within a predetermined distance to the shared resource 10 . Since the determination of proximity is described in the process of describing the controller module 23 of the composite IoT device 20, overlapping content will be omitted. The user terminal 32 may transmit/receive a signal to/from the composite IoT device 20 using short-distance communication such as Wi-Fi, bluetooth, or NFC. The user terminal 32 transmits its GPS coordinates to the composite IoT device 20 to enable the composite IoT device 20 to perform proximity determination.

When it is determined that the user terminal 32 is located within a predetermined distance to the composite IoT device 20 , the composite IoT device 20 may provide a signal indicating that the proximity determination has been passed to the user terminal 32 . When the proximity determination is passed, the composite IoT device 20 and the user terminal 32 may request the blockchain network 50 to execute a one-time authentication protocol. When the execution request of the one-time authentication protocol received from the composite IoT device 20 and the user terminal 32 matches, the blockchain network 50 executes the one-time authentication protocol.

The one-time authentication protocol searches the record of the usage right stored in the block chain 60, determines whether the user terminal 32 has the right to use the shared resource 10 at a predetermined time, and if the use right exists, the one-time authentication protocol generates and provides a one-time key to the composite IoT device 20 and the user terminal 32 . The one-time key may be an arbitrarily generated value, and may be transmitted after being encrypted with the public key of each of the composite IoT device 20 and the user terminal 32 . When the one-time key received by the composite IoT device 20 is matched with the one-time key received by the user terminal 32, the composite IoT device 20 determines that the user terminal 32 has the right to use the lock module (21) can be unlocked. The user can use the shared resource 10 when the lock module 21 is opened. When the lock module 21 is coupled to the existing locking device of the shared resource 10 in an add-on method, the composite IoT device 20 provides the password of the existing locking device to the user terminal 32, and the user uses the user terminal ( The shared resource 10 can be used by inputting the password displayed in 32) into the existing locking device.

The gateway module 27 may monitor the state of the shared resource 10 while the user uses the shared resource 10 . When the shared resource 10 is a space such as a conference room or accommodation facility, when the lock module 21 is opened, the gateway module 27 can sense whether a person enters or leaves the space that is the shared resource 10 . . The gateway module 27 may sense the usage state of the shared resource 10 continuously at a predetermined period or when the lock module 21 is opened. The gateway module 27 may transmit the usage state of the shared resource 10 to the composite IoT device 20 .

The manager terminal 31 may perform an access management function of the shared resource 10 through the manager dApp 41 . The manager terminal 31 can monitor information about users who have applied for use of the shared resource 10 , information about the usage status of the shared resource 10 , usage records and reservation records of the shared resource 10 , etc. there is. The manager dApp 41 may request the manager smart contract 41a to monitor the current state of the shared resource 10, and the manager smart contract 41a is provided by the gateway module 27 from the composite IoT device 20 The use state of one shared resource 10 may be received and provided to the manager terminal 31 through the manager dApp 41 .

The user stops using the shared resource 10 when the usage time based on the usage right is over. The composite IoT device 20 receives information on the usage state of the shared resource 10 from the gateway module 27 when the usage time based on the usage right ends, and operates the lock module 21 to operate the shared resource ( 10) is judged to be blocked. For example, when the shared resource 10 is a space such as a conference room or accommodation facility, the gateway module 27 may sense whether a user exists in the space that is the shared resource 10 , and the space that is the shared resource 10 . When the user does not exist therein, the composite IoT device 20 may perform a use termination step (S40) of controlling the lock module 21 to be locked.

When the user's use is terminated by controlling the composite IoT device 20 to lock the locking module 21 , the composite IoT device 20 transmits the fact of termination to the blockchain network 50 . The user's usage record may be stored in the block chain 60 .
