FIG. 4 is a diagram illustrating a third embodiment in which the information processing device is applied to the system in FIG. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0010] Hereinafter, an embodiment of the present invention will be described with reference to the drawings.

[0011] FIG. 1 is a schematic diagram illustrating an example of an overview of a system to which an information processing device according to an embodiment of the present invention is applied. 1, the information processing device is a wireless terminal that performs wireless communication according to a predetermined wireless communication method, and is a user terminal 2, for example, a smartphone, used by a user U. This information processing device integrally includes a camera 21, a sensor 22, a data file 23, and a blockchain node (hereinafter referred to as a "BC node") in order to realize advanced information processing and secure communication.

[0012] The camera 21 is capable of acquiring high-definition image data and performing face recognition processing, and provides an advanced recognition function when combined with an image processing engine. The microphone for collecting voice, which is one of the sensors 22, has high sensitivity for collecting sound. The acceleration sensor and magnetic sensor detect the precise movement and orientation of the terminal. The GPS sensor enables highly accurate acquisition of location information, and the biometric authentication sensor accurately detects biometric information such as fingerprints and irises. A light sensor, an altimeter, a pressure sensor, a temperature and humidity sensor, and a vibration sensor are implemented to acquire environmental data, and these sensors realize comprehensive monitoring of the surrounding environment.

[0013] The BC nodes in this system shown in Figure 1 adopt a three-tiered structure according to security level and function. The full node at the top holds all the data of the blockchain and provides the computational processing function for generating blocks and the complete storage function for data. This full node functions as the core of the blockchain network and plays an important role in ensuring the integrity and availability of data.

[0014] The light nodes, which are located in the middle layer, are designed as lightweight nodes that perform part of the computational processing and data storage functions. These light nodes can be efficiently implemented as chips and programs, achieving a balance between resource saving and functionality on mobile terminals.

[0015] The lowest-level ultra-light nodes function as the lightest nodes that only perform data transfer functions with the blockchain network. These nodes do not have the computational processing function or data storage function related to block generation, thereby minimizing the resource consumption of the terminal and providing the minimum necessary blockchain connection function.

[0016] The user terminal 2 may be implemented as a full node, or may be designed to operate as a light node or ultra-light node in consideration of security and resource efficiency. This design to operate as a light node or ultra-light node enables operation without storing data in the terminal, and can significantly reduce the risk of information leakage when the terminal is stolen.

[0017] The blockchain network (hereafter referred to as "BCN") shown in Figure 1 adopts a configuration in which more than half of the network is made up of blockchain full nodes (which can be called cloud full nodes because they exist in the cloud) in order to ensure stability and reliability. As shown in Figure 1, the blockchain network BCN has four blockchain full nodes (hereafter referred to as BC full nodes 4). This configuration improves the fault tolerance of the network and guarantees the permanence and availability of data. The BC full nodes 4 ensure redundancy for stable operation of the network and guarantee its reliability as a distributed system.

[0018] The user terminal 2 securely links the blockchain account with its own device identification information and manages it. The own device identification information includes a user account, a smartphone ID, a telephone number, a device number, or SIM card information, and this information is managed in an encrypted state. A network ID, genesis block information, and block connection information are used to manage network connections, and a secure and appropriate network connection is realized by using this information.

[0019] The system related to the user terminal 2 overcomes an important technical constraint in conventional blockchain systems. Conventionally, one BC node was restricted to only be able to connect to a single blockchain network. This restriction made it difficult to link data and share information between different blockchain networks, significantly limiting the flexibility and scalability of the system.

[0020] The system related to the user terminal 2 solves this technical problem and realizes the function that one node can connect to multiple blockchain networks simultaneously. This function is realized by an advanced connection management system that utilizes network IDs and genesis block information. Each network ID uniquely identifies an individual blockchain network, and the genesis block information clearly defines the block that is the starting point of each network.

[0021] The system related to the user terminal 2 uses this identification information to dynamically manage connections to multiple blockchain networks. Each connected network is identified by its own network ID and genesis block information, and the system performs appropriate synchronization processing and data management based on this information. This function enables seamless data integration and information sharing between different blockchain networks.

[0022] The user terminal 2 acquires image data from the camera, sensing data from various sensors, and data files as processing targets, and performs advanced encryption processing on these data. In particular, as authentication data, the analysis results from face recognition, biometric information from biometric sensors, and multi-factor authentication information are processed in an integrated manner to achieve a high level of security.

[0023] Encrypted data is securely recorded via BC nodes. Transactions contain blockchain destination information, network ID, genesis block information, and block connection information, which ensures data integrity and traceability. This security mechanism prevents data tampering and unauthorized access, enhancing the reliability of the entire system. Transactions represent various actions, for example, they are digitally signed, sent to the blockchain network, and added to a block, and the block is linked to the blockchain to finalize the various actions.

[0064] Although one embodiment of the present invention has been described above, the present invention is not limited to the above-described embodiment, and modifications, improvements, etc. within the scope that can achieve the object of the present invention are considered to be included in the present invention.

[0065] Although the information processing device has been described above, the present invention is not limited to a personal computer or a server device, and can be realized as a chip, which is an electronic component, and can be easily incorporated into various conventional devices. For example, in the above-described embodiment, various information is stored in the blockchain network BCN, but this is not particularly limited, and it is sufficient that the information is stored using the blockchain network or distributed management ledger technology.

[0066] For example, the system configuration shown in FIG. 1 and the hardware configuration of the user terminal 2 shown in FIG. 2 are merely examples for achieving the object of the present invention, and are not particularly limited.

[0067] In addition, the functional block diagram shown in Fig. 3 is merely an example and is not particularly limited. In other words, it is sufficient that the information processing system in Fig. 1 is provided with a function capable of executing the above-mentioned series of processes as a whole, and the functional blocks and databases used to realize this function are not particularly limited to the example in Fig. 3.

[0068] Furthermore, the locations of the functional blocks are not limited to those shown in Fig. 3 and may be arbitrary. For example, at least some of the functional blocks arranged in the user terminal 2 may be provided in another information processing device.

[0069] Furthermore, the above-described series of processes can be executed by hardware or software. Furthermore, one functional block may be configured as a single piece of hardware, a single piece of software, or a combination of both.

[0070] When the series of processes is executed by software, the program constituting the software is installed into a computer or the like from a network or a recording medium. The computer may be a computer implemented with dedicated hardware. Furthermore, the computer may be a computer capable of executing various functions by installing various programs thereon, such as a server, a general-purpose smartphone, or a personal computer.

[0071] A recording medium containing such a program may be composed not only of a removable medium (not shown) that is distributed separately from the device main body in order to provide the program to the user, but also of a recording medium that is provided to the user in a pre-installed state in the device main body.

[0072] In this specification, the steps of describing a program to be recorded on a recording medium include not only processes that are performed chronologically according to the order, but also processes that are not necessarily performed chronologically but are executed in parallel or individually.

[0073] In summary, the information processing device and information processing system to which the present invention is applied are only required to have the following configuration, and can take various forms.

[0074] An information processing device (e.g., the user terminal 2 in FIG. 1) is connected to a predetermined network including a plurality of nodes capable of storing information using a blockchain network or a distributed management ledger technology, functions as one node of the predetermined network, and includes a node function means (e.g., the node function unit 101 in FIG. 3) that executes control to transmit and receive information to and from the predetermined network according to the predetermined wireless communication method; The information processing device includes a predetermined network linking means (for example, the predetermined network linking unit 102 in FIG. 3) that links and manages predetermined network identification information capable of identifying the predetermined network and self-identification information capable of identifying the information processing device or its user. This makes it possible to securely protect information during transmission from wireless terminals. It also eliminates the conventional restriction of only being able to connect to a single blockchain network, making it possible to connect to multiple networks.

[0075] The information processing device includes a processing object acquisition means (e.g., a processing object acquisition unit 103 in FIG. 3 ) that acquires, as processing object data, at least a part of image data obtained as a result of imaging by a predetermined camera, sensor data indicating a sensing result of a predetermined sensor, and a predetermined data file; a transaction issuance request unit (e.g., the transaction issuance request unit 104 in FIG. 3) for requesting the issuance of a predetermined transaction based on the data to be processed; The node function means (for example, node function unit 101 in FIG. 3) receives the request and executes control to issue the predetermined transaction. This allows various types of data to be securely captured and recorded using the blockchain.

[0076] In the information processing device, the data stored as the specified transaction using the blockchain or distributed management ledger technology includes at least one of a connection destination or synchronization destination in the specified network, information capable of identifying the specified network, genesis block information, and block connection information. This makes it possible to properly manage connections to multiple blockchain networks and achieve synchronization with each network.

[0077] In the information processing device, the node function means (for example, node function unit 101 in FIG. 3) functions as a node that does not hold data, as the one node of the predetermined network. This makes it possible to minimize the risk of information leakage even if the device is stolen or lost.

[0078] In the information processing device, the processing target acquisition means (for example, the processing target acquisition unit 103 in FIG. 3) further acquires, as the processing target data, one of an analysis result by face authentication or recognition using a camera and biometric information by a biometric information sensor, and other multi-factor authentication information; The node function means (for example, the node function unit 101 in FIG. 3) further encrypts the data to be processed and executes control to store the data using the block chain or the distributed management ledger technology. This makes it possible to safely manage highly confidential data such as biometric information and realize an advanced authentication system combined with multi-factor authentication.

[0079] The information processing device includes a transaction issue request means (for example, the transaction issue request unit 104 in FIG. 3), and judges whether the acquired information is appropriate as a record target. This makes it possible to properly distinguish between important information that should be recorded and information that is not, thereby achieving efficient information management.
