Network system based on blockchain and Artificial Intelligence

Abstract

The present invention relates to a blockchain and artificial intelligence-based network system that blocks abnormal information access from an external network other than that of a registered user in a home network environment and notifies the user of this. If the user's MAC is not authenticated by a blockchain-based program used by the user, traffic is blocked to restrict access by a person other than the user.

Description

Technology Field

[0001] The present invention relates to a blockchain and artificial intelligence-based network system that blocks abnormal access to information from an external network other than a registered user in a home network environment and notifies the user of this. Background Technology

[0002] The problem with current in-home network systems is that privacy is unintentionally exposed through CCTVs or home cameras installed for caring for infants, the elderly, or pets.

[0003] If in-home network systems (refrigerators, lights, etc.) evolve into smart systems that are monitored and controlled, controlling and monitoring these systems from the outside can cause serious problems in terms of personal information protection and privacy.

[0004] Currently, external access to each system (CCTV, home cameras) is controlled using passwords, but if the password is exposed or easily cracked, protection is practically impossible.

[0005] Accordingly, the inventors have conducted research on a home network technology that can prevent unauthorized leakage of user data by performing user authentication based on blockchain (IOTA) in the home network and monitoring traffic using artificial intelligence to block abnormal access (unknown traffic types). Prior art literature

[0007] The present invention aims to provide a blockchain and artificial intelligence-based network system that can prevent unauthorized leakage of user data by performing user authentication based on blockchain (IOTA) in a home network and monitoring traffic using artificial intelligence to block abnormal access (unknown traffic types). means of solving the problem

[0008] According to one aspect of the present invention for achieving the above-mentioned purpose, a blockchain and artificial intelligence-based network system that blocks abnormal information access from an external network other than a registered user in a home network environment and notifies the user of this is implemented to restrict access by a person other than the user by blocking traffic if the user's MAC is not authenticated by a blockchain-based program used by the user. Effects of the invention

[0009] The present invention has the effect of preventing unauthorized leakage of user data by performing user authentication based on blockchain (IOTA) in a home network and monitoring traffic using artificial intelligence to block abnormal access (unknown traffic types). Brief explanation of the drawing

[0010] FIG. 1 is a flowchart of the operation of a blockchain and artificial intelligence-based network system that blocks abnormal information access from an external network other than a registered user in a home network environment according to the present invention and notifies the user of this. Specific details for implementing the invention

[0011] The foregoing and additional aspects are embodied through embodiments described with reference to the attached drawings. It is understood that the components of each embodiment may be combined in various ways within the embodiment or with components of other embodiments, unless otherwise stated or contradicted. Based on the principle that the inventor may appropriately define the concepts of terms to best describe his invention, the terms used in this specification and claims shall be interpreted in a meaning and concept consistent with the description or proposed technical idea.

[0012] Blocks referred to as 'circuits' in this specification may be composed of hardware such as dedicated semiconductors, gate arrays, FPGAs, or parts thereof. One or more blocks may be implemented as a single piece of hardware. As another example, these blocks may be implemented in software as an information processing device in which a computing element executes program instructions stored in a memory element. Multiple blocks may be implemented as part of a program executed on the same computing element.

[0013] As another example, these blocks may be implemented in a hybrid form where part of the individual circuit is hardware and part is software. Additionally, in the software implementation, the computational elements may include digital signal processors, dedicated computational processors, artificial intelligence processing engines, dedicated AI processors, and graphics processors, or a combination thereof to the extent possible.

[0014] Hereinafter, the present invention will be described in detail through preferred embodiments described with reference to the attached drawings so that those skilled in the art can easily understand and reproduce it. Although specific embodiments are illustrated in the drawings and detailed descriptions are provided, this is not intended to limit the various embodiments of the present invention to a specific form.

[0015] In describing the present invention, if it is determined that a detailed description of related known functions or configurations could unnecessarily obscure the essence of the embodiments of the present invention, such detailed description will be omitted.

[0016] When it is stated that one component is "connected" or "joined" to another component, it should be understood that while it may be directly connected or joined to that other component, there may also be other components in between.

[0017] On the other hand, when it is stated that one component is "directly connected" or "directly coupled" to another component, it should be understood that no other component exists in between.

[0018] FIG. 1 is a flowchart of the operation of a blockchain and artificial intelligence-based network system that blocks abnormal information access from an external network other than a registered user in a home network environment according to the present invention and notifies the user of this.

[0019] A blockchain and artificial intelligence-based network system according to the present invention, which blocks abnormal information access from an external network other than a registered user in a home network environment and notifies the user of this, blocks traffic and restricts access by a person other than the user if the user's MAC is not authenticated by a blockchain-based program used by the user.

[0020] A blockchain and artificial intelligence-based network system according to the present invention, which blocks abnormal information access from an external network other than that of a registered user in a home network environment and notifies the user of this, typically contacts a stored contact when accessing with a MAC other than the MAC of the user's PC or smartphone, since the user usually uses their own PC or smartphone.

[0021] A blockchain and artificial intelligence-based network system according to the present invention, which blocks abnormal information access from an external network other than a registered user in a home network environment and notifies the user thereof, installs a blockchain-based program on network equipment at the wireless AP (Access Point) and edge to perform user authentication, and operates a Watch Dog program capable of analyzing traffic patterns using artificial intelligence, and if the traffic pattern is not normal, blocks it and outputs a message to the user that there is an attempt to leak data.

[0022] The authentication program is an IOTA-based authentication program that receives and stores the user's MAC address internally, thereby storing and managing information about terminals that have undergone legitimate procedures.

[0023] The AI-based Watch Dog program periodically searches the system's ARP table to check if any unauthorized MAC addresses are registered, and performs monitoring of communication between MACs that come in via WiFi.

[0024] Typically, communication between WiFi clients does not occur, and cases where printers or servers are connected wirelessly are excluded, as most printers or servers exist on wired networks. AI-based abnormal network traffic pattern analysis analyzes traffic flow, including DOS and DDOS.

[0025] Accordingly, access by unauthorized terminals can be blocked, designated users can be warned about unwanted access attempts, and the integrity of personal data can be guaranteed.

[0026] By implementing it in this way, the present invention can prevent unauthorized leakage of user data by performing user authentication based on blockchain (IOTA) in a home network and monitoring traffic using artificial intelligence to block abnormal access (unknown traffic types).

[0027] The various embodiments disclosed in this specification and drawings are provided merely as specific examples to aid understanding and are not intended to limit the scope of the various embodiments of the invention.

[0028] Accordingly, the scope of the various embodiments of the present invention should be interpreted as including all modifications or variations derived based on the technical concept of the various embodiments of the present invention, in addition to the embodiments described herein. Industrial applicability

[0029] The present invention is industrially available in the field of in-home network technology and the field of application technology thereof. Explanation of the symbols
