Description

Electronic devices and operating methods for an event data management system using distributed ledger technology

[0001] The present invention relates to electronic devices and their operating methods. More specifically, the present invention relates to electronic devices and their operating methods for an event data management system using distributed ledger technology.

[0002] With the advancement of information technology, including artificial intelligence, the importance of data security technology is increasing. Research is underway on distributed ledger technologies like blockchain, which can verify data integrity to prevent data forgery and manipulation. However, blockchain technology has limitations in applying it to event data management, which requires rapid data sharing, due to the significant time required to propagate data across multiple nodes and verify data integrity. Therefore, it is necessary to develop an event data management system utilizing distributed ledger technology that can secure data integrity while enabling rapid data sharing among nodes.

[0003] The problem to be solved by the present invention is to provide electronic devices and operating methods for an event data management system that can quickly share event data between nodes while ensuring data integrity, thereby enabling safe and rapid event response and action.

[0004] According to one embodiment of the present invention, an autonomous vehicle for an event data management system using distributed ledger technology includes a sensing unit, a storage unit, a communication unit, and a processor, wherein the processor monitors whether an event has occurred from sensing data acquired through the sensing unit, controls the storage unit to store first event data for the first event when a first event has occurred, selects one of nodes constituting a distributed network based on a location where the first event has occurred, and controls the communication unit to transmit the first event data to the selected node.

[0005] According to one embodiment of the present invention, an organization node for an event data management system using distributed ledger technology includes a storage unit, a communication unit, and a processor, wherein the processor controls the storage unit to store the event data when receiving event data including a location where an event occurred from a first node among nodes constituting a distributed network, selects a second node among nodes constituting the distributed network based on the location where the event occurred, and controls the communication unit to transmit the event data to the second node.

[0006] According to one embodiment of the present invention, a method for operating an autonomous vehicle for an event data management system using distributed ledger technology may include a step of monitoring whether an event has occurred from sensing data, a step of storing first event data for a first event when a first event has occurred, a step of selecting one of nodes constituting a distributed network based on a location where the first event has occurred, and a step of transmitting the first event data to the selected node.

[0007] According to one embodiment of the present invention, an operation method of an organization node for an event data management system using a distributed ledger technology may include, when event data including a location where an event occurred is received from a first node among nodes constituting a distributed network, a step of storing the event data, a step of selecting a second node among nodes constituting the distributed network based on the location where the event occurred, and a step of transmitting the event data to the second node.

[0008] According to one embodiment of the present invention, a non-transitory computer-readable medium storing computer instructions that, when executed by a processor of an electronic device, cause the electronic device to perform an operation, the operation may include a step of monitoring whether an event has occurred from sensing data, a step of storing first event data for the first event when a first event has occurred, a step of selecting one of nodes constituting a distributed network based on a location where the first event has occurred, and a step of transmitting the first event data to the selected node.

[0009] According to one embodiment of the present invention, a non-transitory computer-readable medium storing a computer instruction that, when executed by a processor of an electronic device, causes the electronic device to perform an operation, the operation may include: when event data including a location where an event occurred is received from a first node among nodes constituting a distributed network, storing the event data; selecting a second node among the nodes constituting the distributed network based on the location where the event occurred; and transmitting the event data to the second node.

[0010] According to one embodiment of the present invention, data integrity can be ensured using distributed ledger technology. According to one embodiment of the present invention, when an autonomous vehicle detects an event, it transmits event data to some nodes, and the node receiving the event data transmits the event data to at least one other node. This allows the event data to be shared with the nodes more quickly than when the autonomous vehicle detects the event directly transmits the event data to all nodes. Furthermore, since the event data sharing target is limited to nodes determined based on the location where the event occurred, the time required for event data sharing can be shortened compared to when the event data is shared with all nodes. Therefore, according to one embodiment of the present invention, data integrity can be secured while enabling rapid event data sharing, thereby enabling a safe and rapid response to events such as traffic accidents or emergency patient occurrences.

[0027] Hereinafter, the operating principles of preferred embodiments of the present invention will be described in detail with reference to the attached drawings. Furthermore, when describing embodiments of the invention, detailed descriptions of related known functions or configurations will be omitted if they are deemed to obscure the gist of the present disclosure. Furthermore, the terms used below are defined based on their functions in the present invention and may vary depending on the intent or custom of the user or operator. Therefore, the definitions of the terms used should be interpreted based on the contents and corresponding functions throughout this specification.

[0028] FIG. 1 is a conceptual diagram schematically illustrating an event data management system (10) using distributed ledger technology according to one embodiment of the present invention.

[0029] Referring to FIG. 1, the event data management system (10) may include a distributed network (DN) comprising a plurality of nodes. The plurality of nodes may include autonomous vehicles (100A to 100C) and agency nodes (200A to 200D). Although FIG. 1 illustrates the distributed network (DN) as comprising three autonomous vehicles (100A to 100C) and four agency nodes (200A to 200D), the number of nodes included in the distributed network (DN) is not limited thereto. Each node may also be referred to as an electronic device.

[0030] Here, an event may refer to the occurrence of various emergency situations, including traffic accidents, fires, occurrence of critical patients, discovery of wanted vehicles, natural disasters, and crimes. The agency nodes may include nodes of various agencies responding to such events, such as a hospital node (200A), an insurance company node (200B), a police station node (200C), a fire station node (200D), and a Road Traffic Authority node. In other words, the types of nodes constituting the distributed network (DN) may include, for example, autonomous vehicles, hospital nodes (200A), insurance company nodes (200B), police station nodes (200C), and fire station nodes (200D).

[0031] A plurality of nodes (100A to 100C and 200A to 200D) may be capable of communicating with each other. The autonomous vehicles (200A to 200C) may collect sensing data through a sensing unit and monitor whether an event occurs from the sensing data. The autonomous vehicles (200A to 200C) may store event data regarding the event when an event occurs. The autonomous vehicles (200A to 200C) may transmit the event data to at least one of the sharing target nodes so that the event data is shared among the sharing target nodes determined based on the location where the event occurred among the plurality of nodes (100A to 100C and 200A to 200D). In one embodiment, the autonomous vehicles (200A to 200C) may store the event data when receiving event data from another node and transmit the event data to at least one of the sharing target nodes so that the event data is shared among the nodes determined based on the location where the event occurred.

[0032] When the organization node (200A to 200D) receives event data, it can store the event data and transmit the event data to at least one of the sharing target nodes so that the event data is shared among the sharing target nodes determined based on the location where the event occurred.

[0033] In one embodiment, the sharing target node may be determined by considering not only the location where the event occurred, but also the type of event. In one embodiment, when nodes (100A to 100C and 200A to 200D) transmit event data to other nodes, they may additionally transmit additional event data about the events they have collected to the event data receiving node. In one embodiment, unlike a blockchain, nodes (100A to 100C and 200A to 200D) may verify the integrity of the event data using a directed acyclic graph.

[0034] FIG. 2 is a conceptual diagram schematically illustrating event data propagation between nodes constituting a distributed network of an event data management system using distributed ledger technology according to one embodiment of the present invention.

[0035] Referring to FIG. 2, an example is illustrated in which a second autonomous vehicle (100B) detects an event, and the event data (E1) is shared with a first autonomous vehicle (100A), an insurance company node (200B), a police station node (200C), and a fire station node (200D). In one embodiment, the sharing target node may be determined based on the jurisdiction of the agency node in the case of an agency node, or based on the driving route in the case of an autonomous vehicle. For example, the sharing target node may be an agency node that has jurisdiction over the location where the event occurred, or an autonomous vehicle whose driving route is within a predetermined distance from the location where the event occurred. In one embodiment, the sharing target node may additionally be determined based on the type of event. For example, if the event type is the discovery of a wanted vehicle, the sharing target node may include a police station node (200C) that has jurisdiction over the location where the event occurred. For another example, if the event type is an emergency patient occurrence, the sharing target nodes may be a hospital node (200A) that has jurisdiction over the location where the event occurred, a police station node (200C), a fire station node (200D), and an autonomous vehicle (100A) whose driving path is within a predetermined distance from the location where the event occurred.

[0036] The second autonomous vehicle (100B) can select one of the sharing target nodes and transmit event data (E1) to the selected node. In one embodiment, the second autonomous vehicle (100B) can randomly select one of the sharing target nodes at predetermined time intervals and transmit event data (E1) to the selected node until the event data is shared across all sharing target nodes. For example, the second autonomous vehicle (100B) can transmit event data (E1) to a police station node (200C) and then, after a predetermined time has elapsed, transmit event data (E1) to an insurance company node (200B).

[0037] The police station node (200C) that receives the event data (E1) may select one of the sharing target nodes and transmit the event data (E1) to the selected node. In one embodiment, the police station node (200C) may randomly select one of the sharing target nodes at predetermined time intervals and transmit the event data (E1) to the selected node until the event data is shared across all sharing target nodes. For example, the police station node (200C) may transmit the event data (E1) to the fire station node (200D) and, after a predetermined time has elapsed, transmit the event data (E1) to the first autonomous vehicle (100A). In one embodiment, the police station node (200C) may additionally transmit additional event data (E1') containing additional information about the event to the fire station node (200D). The additional event data (E1') may include information that the organization possesses, creates, or collects on its own in relation to the event. For example, the police station node (200C) can additionally transmit additional event data (E1') containing information on the scale of the fire obtained through CCTV to the fire station node (200D).

The directed acyclic graph can represent the history of event data transmission between multiple nodes. For example, if a first node transmits event data to a second node, the directed acyclic graph can represent this transmission action as a first vertex corresponding to the first node, a second vertex corresponding to the second node, and an edge connecting the first vertex and the second vertex. In one embodiment, the storage unit (110) can store sensing data acquired through the sensing unit (140). The storage unit (110) can store, for example, an operating system and application programs.

[0048] In one embodiment, the location where the second event occurred may be located within a predetermined distance from the driving path of the autonomous vehicle.

[0049] In one embodiment, each of the first node and the second node may be an agency node that governs the location where the second event occurred or another autonomous vehicle whose driving path is within a predetermined distance from the location where the second event occurred.

[0050] In one embodiment, the first event data may include the location where the first event occurred, the time the first event occurred, and the type of the first event.
