Description

Convolutional Neural Network (CNN)-based image value judgment and distributed storage method of data using blockchain technology {Method for saving to distributed data employing image value deciding based in CNN and blockchain driving}

The content disclosed in this specification relates to data storage and management technology using blockchain. More specifically, when information that a customer wants to store is stored and managed through blockchain, the information is stored safely on blockchain. , to maintain excellent security.

Unless otherwise indicated herein, the material described in this section is not prior art to the claims of this application, and is not admitted to be prior art by inclusion in this section.

In general, for example, videos of specific individuals stored on a customer's mobile terminal, etc. need to be protected as personal information in a situation where a lot of information is viewed, searched, used, etc., and the copyright, portrait rights, etc. of such videos are required. It also protects.

In addition, for this purpose, it is determined whether the video violates copyright/portrait rights and is harmful, and the analysis results and video can be stored on a blockchain server.

And in these cases, blockchain has high information availability because other devices continue to operate even if there is a power outage or a failure in the connection between devices.

On the one hand, these blockchains use an existing centralized information storage service method, which protects the data of many individuals. And, upon closer inspection, it is known that there is a risk of losing all data if a problem occurs in the central server itself.

So, for this purpose, an information sharing service was created, and this sharing service allows users to upload files to a shared server on the web and then upload the files to the shared server using a computer or mobile communication terminal at home or work. Allows you to open, edit, and save. Alternatively, music files or video files stored on a shared server can be downloaded or viewed through streaming. This allows various devices such as personal PCs and smartphones to be used as terminals, and also has the advantage of keeping user data safe by storing it on a highly reliable server.

And, according to conventional sharing services, a common method for users to access data on a server is to install a general-purpose disk sharing application and then log in. In other words, the user downloads and installs the disk sharing application provided by the sharing service provider on a personal PC and/or smartphone or mobile phone, then logs in by entering the already set ID and password. You can access the disk space allocated to your account on the server not only on your smartphone or mobile phone when you are on the move, and you can upload or download files to this space. And anyone can freely download and install the disk sharing application provided by the sharing service provider. In this case, the right to access the user's data is protected only by 'ID and password'.

Prior art documents against this background include the patent documents below.

(Patent Document 1) KR102008757 Y1

For reference, similar to this specification, the technology of Patent Document 1 relates to a blockchain-based data security method.

In addition, this method includes the steps of generating information, encrypting it, and storing it in local storage, determining the data to be distributed and processed for the stored information according to setting conditions, and dividing the determined information into several pieces according to setting conditions. Security processing is carried out, including the partitioning step.

The disclosed content is a convolutional neural network-based image value judgment and data storage using blockchain technology that maintains excellent security by safely storing information on a blockchain when personal video information, etc., is stored on a blockchain server. We want to provide a distributed storage method.

The convolutional neural network-based image value judgment and distributed storage method of data using blockchain technology according to the embodiment are:

When storing information that you wish to protect as personal video information on a blockchain server, excellent security is maintained by storing personal information or files in a blockchain-based storage format.

Also, in this case, unlike existing centralized storage systems, information or files are encrypted and stored and recorded on multiple distributed computers, thereby improving the advantage of decentralization and availability, thereby permanently storing data stably and efficiently. Do it as

Specifically, the distributed storage method for such data is,

When the information the customer wants to store is stored and managed through blockchain, the control unit of the service information processing device that will connect to the blockchain network uploads the information desired by the customer through the customer terminal and uploads it to the blockchain network, thereby securing security. In terms of how to manage it,

When storing information or files desired by a customer through the blockchain, the ChainDrive format that encrypts and stores the information or files in a number of different distributed storages is preset and registered,

The chain drive format is,

A third step of not executing the Chain Drive format if the customer information is not registered customer information; and

When the ChainDrive format is started to be executed, a fourth step of uploading the customer's desired information (or file) from the ChainDrive format, uploading it to the registration blockchain network, encrypting and storing it in a number of different distributed storages; It is characterized by including.

According to embodiments, when information desired to be protected as personal video information is stored on a blockchain server, excellent security is maintained by storing personal information or files in a blockchain-based storage format.

In addition, unlike existing centralized storage systems, this blockchain-based storage format encrypts and stores and records information or files on multiple distributed computers, providing the advantage of decentralization and increasing availability, allowing data to be stored reliably and efficiently. Store permanently.

And, for example, by providing a paid service for the application to individual users (B2C), we can provide a service that allows customers to safely retain their images in the form of paying a user fee. Sometimes it happens.

Furthermore, in connection with this content, it is possible to determine whether images owned by individual users have copyright, portrait rights, and whether or not they are trendy, thereby ensuring that specific images of such individuals can be safely stored. In addition, we provide a content management solution that safely manages numerous contents generated from work, such as photos, videos, and documents.

Figure 1 is a diagram conceptually illustrating a method for determining image value based on a convolutional neural network and distributed storage of data using blockchain technology, according to an embodiment.

As shown in Figure 1, the distributed storage method of data in one embodiment is to store personal information or files in a blockchain-based storage format when information that is desired to be protected as personal image information is stored in a blockchain server. By doing so, excellent security is maintained (see a).

Also, in this case, unlike existing centralized storage systems, information or files are encrypted and stored and recorded on multiple distributed computers, thereby improving the advantage of decentralization and availability to permanently store data stably and efficiently.

This distributed storage method of data provides the following features.

1) As a decentralized service, it minimizes concerns about data loss by excluding concerns about service interruption.

2) Materials such as documents and photos can be permanently recorded and easily managed.

In addition, if we look at a use case for this distributed storage method of data, in the case of a content business operator, the content can be used at any time by storing it according to this embodiment. In addition, in the case of small and medium-sized businesses, important business files can be backed up and used permanently according to one embodiment.

In addition, sole proprietors can store valuable customer information, and in the case of a one-person business, there is no additional cost to store files, making it more efficient than other services. And in the case of publishing & design, we also provide solutions for managing copyrighted works and portfolios.

Additionally, this method of distributed storage of data effectively provides services in the following situations, for example (see b).

Specifically, video (image) information is uploaded through a specific app in the customer's mobile terminal, feature vectors of the uploaded video are extracted from a server in one embodiment, and whether the video is infringed on copyright/portrait rights and whether it is harmful is determined. , the analysis results and images are saved as files. To elaborate, this image information also represents the customer's face information, etc. In addition, the value of these customer face images is judged as individual information and stored with high security.

And, for example, this method uses a convolutional neural network to determine whether a photo violates copyright and portrait rights and whether it is harmful.

Therefore, in order to ensure the stability of the image information analyzed in this way, it is moved to the aforementioned storage and stored and stored safely.

In this case, once recorded in the storage, excellent security is maintained as the information cannot be tampered with, and unlike existing centralized storage configurations, the information can be encrypted and stored and recorded on multiple distributed computers, providing decentralization. It stores information reliably and efficiently by increasing its advantages and availability.

Therefore, through this, the existence of copyright, portrait rights, and prevalence of images owned by individual users are determined, and the specific images of such individuals are safely stored. In addition, we provide a content management solution that safely manages numerous contents generated from work, such as photos, videos, and documents.

In addition, it automatically filters and classifies problematic content such as copyright and confidential information to enable safe storage and management of information. And in these cases, the value of the image is judged and provided to the consumer.

Figure 2 is a diagram illustrating the overall system applying a convolutional neural network-based image value judgment and a distributed data storage method using blockchain technology according to an embodiment.

As shown in FIG. 2, the system of one embodiment includes a plurality of different customer terminals 100, a web server 200 (i.e., service information processing device) equipped with a distributed data storage method of one embodiment, and storage. .

Additionally, the system according to one embodiment performs services through external linkage in conjunction with the web server 200, and includes a troubleshooting center information processing device (not shown).

Additionally, at this time, each device connects to each other through its own network. In this case, they connect to each other using TCP/IP, etc., and use Wi-Fi or LTE wirelessly with mobile terminals among customer terminals.

The customer terminal 100 goes through a login process to be authenticated as a member in order to access the blockchain server, that is, the web server. In general, the login process is performed by entering one ID and one password for one member account. In contrast, in one embodiment, this authentication is a two-step procedure for accessing the disk space allocated to the member account. In other words, first, the customer terminal uses the authentication information to authenticate the member, and after the connection step using this authentication information, the user logs in by entering a password. Grant access to disk space. Here, the member ID may be the member's email address. Meanwhile, a specific customer terminal may be, for example, a user's mobile phone or smartphone, and the unique identification information may be a terminal device with unique identification information such as a mobile phone unique terminal number (IMEI; International Mobile Equipment Identify) or a mobile phone number. Since the terminal number is assigned to the terminal by the manufacturer of the terminal device, each terminal can be uniquely identified. Additionally, the mobile phone number, that is, the mobile phone number, is also used as information to uniquely identify the terminal in the case of a terminal that includes a mobile phone function. Therefore, through this, one authentication information and two or more multiple passwords are registered for each member, and access rights to disk space are differentially granted to the terminals of users logged in through each password. Therefore, it reduces the risk that information shared on the private disk space of the blockchain server will be exposed to unwanted third parties. Furthermore, the server's disk space can be shared only between terminals that have installed the application including the user's specific terminal and authentication information consisting of unique identification information for this specific terminal. Therefore, this provides effects such as reducing the risk of information shared on the server being exposed to unwanted third parties.

The web server (i.e., service information processing device) 200 is a main server that provides blockchain services and can be configured to include a blockchain that provides personal disk space accessible to members. And, according to one embodiment, when storing personal video information, etc. on a blockchain server, the web server 200 stores personal information or files in a blockchain-based storage format to maintain excellent security. do. Also, in this case, unlike existing centralized storage systems, information or files are encrypted and stored and recorded on multiple distributed computers, increasing the advantage of decentralization and availability to permanently store data stably and efficiently.

The storage allocates personal disk space to each member account, and this personal disk space is used like disk space in a customer terminal when running a blockchain-based service.

Figure 3 is a block diagram showing the configuration of a service information processing device used in a convolutional neural network-based image value judgment and a distributed storage method of data using blockchain technology according to an embodiment.

As shown in FIG. 3, the service information processing device 200 of one embodiment includes an I/F unit 201 for transmitting and receiving various information to and from the outside, a main processing unit 202 and a database 203 for controlling the same. do.

Additionally, the service information processing device 200 according to one embodiment includes a key signal input unit 204 that receives various setting information according to the user's key operation and a display unit 205 that displays various monitoring information.

The I/F unit 201 is connected to the external customer terminal 100 and storage to transmit and receive customer information (company name or business number) and data distribution information such as video information or files that the customer wants to store. .

First, as before, when the main processing unit 202 stores and manages the information desired by the customer through blockchain, it connects to the corresponding blockchain network and uploads the information desired by the customer through the customer terminal and uploads it to the blockchain network. By doing so, security management is carried out. In this state, according to one embodiment, when the main processing unit 202 first stores information or files desired by the customer through the blockchain, the information or files are encrypted and distributedly stored in a number of different distributed storages. Register the chain drive format in advance. And, the chain drive format is as follows, for example. That is, a) First, query each storage for the available job list. b) And, as a response to the query, task information including a task ID, distributed task ID, and Merkle root (merkle_root) is obtained from each storage. c) So, after classifying the available information according to the above work information, the information or files are distributed and encrypted differently according to the available storage information (including the number), and also the hash required to prove the hash of the Merkle root It is composed and provided separately. Therefore, the main processing unit 202 uploads the information (or files) desired by the customer from the ChainDrive format to the customer terminal 100, uploads it to the registration blockchain network, encrypts and stores it in a number of different distributed storages. do. For reference, more specific points are explained in detail below.

The database 203 stores and manages customer information, storage registration information, image information desired by the customer, etc. under the control of the main processing unit 202.

FIG. 4 is a flow chart sequentially showing a method of determining image value based on a convolutional neural network and distributing data using blockchain technology according to an embodiment (see FIG. 3).

As shown in Figure 4, the method of one embodiment is to first store and manage the information that the customer wants to store through blockchain as before, then connect to the blockchain network and upload the information that the customer wants through the customer terminal. Receive it and upload it to the blockchain network for security management.

In this state, the method according to one embodiment sets and registers the chain drive format as described above in advance (S401).

And, in this case, when the ChainDrive format first stores information or files desired by a customer through blockchain, the information or files are encrypted and distributed and stored in a number of different distributed storages.

And, specifically, the chain drive format is as follows.

a) First, query each storage for the available job list.

For example, when first querying each storage for a list of available tasks through the ChainDrive format, the most previously registered task ID and distributed processing ID in the corresponding storage are found and queried.

b) And, as a response to the query, task information including a task ID, distributed task ID, and Merkle root (merkle_root) is obtained from each storage.

c) So, after classifying the available information according to the above work information, the information or files are distributed and encrypted differently according to the available storage information (including the number), and also the hash required to prove the hash of the Merkle root It is composed and provided separately.

Next, with this ChainDrive format registered, when customer information is input through the customer terminal (S402), the customer information is connected to the registered ChainDrive access address (S403) and the ChainDrive format is executed.

Additionally, in this case, for example, access rights to access the blockchain space are granted by logging in using the password entered by the customer as described above.

In addition, this corresponding authentication information is configured only for one member account, and includes unique identification information including the customer's ID, terminal number, or mobile communication phone number.

In addition, the password ensures that there are at least two different passwords for one member account, and each password is differentially granted access to content stored in each storage.

So, through this, under a blockchain situation, users can use only the content materials they select among the content materials stored in the disk space allocated to them, reducing exposure to unwanted third parties.

Meanwhile, when connecting to the Chain Drive access address like this, the customer information is compared with the registered customer information, and if the customer information is registered customer information, it is confirmed that the customer is a normal customer (S404) and the Chain Drive format is executed. Begin.

On the other hand, if the customer information is not registered customer information, the Chain Drive format is not executed.

So, when this ChainDrive format is started, the customer's desired information (or file) is uploaded from the ChainDrive format (S405), uploaded to the registered blockchain network, encrypted and stored in a number of different distributed storages. Do it (S406).

As described above, in one embodiment, when storing personal video information, etc. on a blockchain server, excellent security is maintained by storing personal information or files in a blockchain-based storage format.

Also, in this case, unlike existing centralized storage systems, information or files are encrypted and stored and recorded on multiple distributed computers, thereby improving the advantage of decentralization and availability to permanently store data stably and efficiently.

Therefore, through this, one embodiment allows, for example, to provide paid services of the application to individual users (B2C), allowing customers to safely retain their images in the form of paying a user fee. It also allows us to provide services.

Furthermore, in connection with this content, one embodiment determines whether an image possessed by an individual user has copyright, portrait rights, and whether or not it is trendy, thereby enabling the safe storage of the individual's specific image. In addition, we provide a content management solution that safely manages numerous contents generated from work, such as photos, videos, and documents.

In addition, it is possible to safely store and manage information by automatically filtering and classifying problematic content such as copyright and confidential information. In this case, the value of the image can be judged and provided to consumers.

Meanwhile, in addition to this, this method of distributed storage of data further includes the following configuration to distribute information to each storage and store it with encryption in such cases, thereby enabling distributed storage of data to be more effective.

Specifically, when encrypting data for distributed storage, this configuration generates n (number of storage) pieces of distributed information using the secret key and exclusive OR characteristics. Then, n partial secret keys are generated using this information, and the encrypted distributed data and partial secret key are stored in each of the n storages, thereby performing encryption.

To briefly explain this background, as terminals become more high-performance and high-capacity, the importance of protecting and managing important data inside the terminal is emerging.

To protect and manage such important data, a method of backing up the important data of a terminal by encrypting it and storing it in an external storage device has been used in the past.

However, if important data is stored in an external storage device, a problem may arise where important data is easily leaked if the storage device is hacked.

Therefore, when storing important data in an external storage device, a more secure method is required.

On the other hand, in this case, the method of entering random initial values and secret keys is blocked by using scrambling, thereby performing distributed storage of data more effectively.

To this end, first, when encrypting in the Chain Drive format, information or files are encrypted using the encryption configuration below and provided to each storage.

And also, the encryption configuration is as follows.

a) When the customer receives the desired information (or File -> plain text format), a different secret key is selected depending on the shape or length of the plain text.

Also, according to the size of the secret key, one of a number of different rounds is selected and executed repeatedly to obtain the ciphertext.

In addition, the function for each round applies the ARIA (Academy Research Institute Agency) encryption format, which includes round key addition, substitution layer, and diffusion layer.

b) Therefore, before performing the round key addition operation, the plaintext and the secret key are modulated by first performing exclusive OR with n-1 scramblers (n is the number of storage).

c) Then, set this falsification information into n partial secret keys, and provide one different partial secret key to each of the n storages.

d) So, when the modulation is performed in this way, the ciphertext is obtained by repeatedly executing it as a function for each round including one round of round key addition operations according to the secret key size.

And, whenever the ciphertext (format) is acquired (including storage), the scrambler systematically destroys the round key addition operation and the operation result is obtained in the same format as the commercial AES (Advanced Encryption Standard).

Meanwhile, in addition to this, the above distributed data storage method, when encrypted in this way, enables distributed storage of data in the following configuration, thereby enabling effective distributed storage in another aspect.

For example, this configuration first constructs a secret key equal to n-1 scrambles, that is, the number of storage minus one, and creates n distributed data using this secret key.

To explain more specifically, a t-1st order random polynomial (f(x)) with a constant term as secret data is selected, and values from 1 to n are assigned to x of the t-1st order random polynomial (f(x)). By substituting, n pieces of distributed information can be generated. At this time, t represents the number of distributed data required to recover secret data.

Then, configure a specific secret key.

Next, n-1 random keys, that is, n-1 scrambles, are generated, and both the secret key and the n-1 random keys are bitwise XORed.

Then, this information can be set into n partial secret keys, and a different partial secret key can be transmitted to each of the n storages.

Then, each of the n pieces of distributed data is encrypted with a secret key to generate n pieces of encrypted distributed information.

Then, n pieces of encrypted distributed data are each transmitted to the corresponding n pieces of storage and stored. For reference, this method is also used in the same way as the above method.

Therefore, before transmitting encrypted distributed data, a process can be performed to verify whether n storage units are legitimate users.

Meanwhile, this method explains the process of recovering the distributed and stored data when encrypted in this way.

First, when receiving a request to recover secret data, encrypted distributed data is received from at least t of the n storages. In this case, before receiving encrypted distributed data, an authentication process with t storage units can be performed.

Then, configure the secret key

For example, if a secret key is stored internally, this secret key is used, and if not, a secret key is created separately. And in this case, if the secret key cannot be configured internally, the secret key can be obtained through n storages.

Obtaining a secret key through n storages involves authenticating with each of the n storages, receiving n partial secret keys from the n storages, and performing a bitwise exclusive OR (Bitwise XOR) on all the n partial secret keys received. ) to create a secret key. This method may additionally be used together with the two methods described above.

Then, t pieces of encrypted distributed data are decrypted with a secret key to generate t pieces of distributed data.

And also, the secret data is recovered using t distributed data.

To explain the process of recovering secret data in more detail, a t-1st order random polynomial (f(x)) is recovered using t distributed data, and the constant term of the t-1st order random polynomial (f(x)) is You can check and recover the constant term as secret data.

Additionally, during the process of distributing and storing secret data in this method, the process of generating distributed data is explained a little further as follows.

First, n pieces of distributed data (S1, S2, ...Sn) are created using the secret data to be distributed and stored.

Then, in order to generate n distributed data, a t-1st order random polynomial (f(x)) with a constant term as secret data is selected, and the x of the t-1st order random polynomial (f(x)) is divided from 1 to n. You can generate n distributed data (S1, S2, …Sn) by substituting values up to . At this time, t represents the number of distributed data required to recover secret data.

And, distributed information is also stored in the blockchain. In this case, the distributed information may include user identification information, the master storage selected by the user, a list of n storages selected by the user, and the number (t) of distributed data required for recovery.

Additionally, you can request a secret key for the distributed storage service by performing the master storage authentication process.

Then, if authentication is successful, the master storage verifies the record of distributed information stored in the blockchain.

Meanwhile, in addition to this, the process of generating encrypted distributed data during the process of distributing and storing secret data in this method is explained as follows.

First, the master storage then generates a secret key (V) and generates n partial secret keys (V1, V2, ...Vn) using the secret key (V).

Master storage generates n-1 random keys, sets the n-1 random keys to n-1 partial secret keys (V1, V2, …Vn-1), and combines the secret key and n-1 random keys. A partial secret key (Vn) is generated by performing bitwise exclusive OR (Bitwise XOR). So, finally, n partial secret keys (V1, V2, …Vn) are generated.

Then, the master storage transmits the generated secret key and records the transmission of the secret key to the blockchain.

Additionally, when a secret key is received from the master storage, each of the n pieces of distributed data (Si) is encrypted with the secret key to generate n pieces of encrypted distributed data (Ti).

On the other hand, during the process of distributing and storing secret data in this method, the process of transmitting encrypted distributed data to storage devices and completing distributed storage is explained.

First, an authentication procedure is performed with a storage device that does not transmit encrypted distributed data among n storage devices.

Then, the encrypted distributed data corresponding to the authenticated storage is transmitted to the authenticated storage device. That is, the i-th encrypted distributed data (Ti) is transmitted to the i-th storage device.

When the i-th storage device receives the i-th encrypted distributed data (Ti), it records in the blockchain that it has received the i-th encrypted distributed data (Ti) and sends the ith partial secret key (Vi) to the master storage. request.

When the master storage receives a request for the i-th partial secret key (Vi), it transmits the i-th partial secret key (Vi) among the n generated partial secret keys to the i-th storage device.

When the i-th storage device receives the i-th partial secret key (Vi), it records in the blockchain that it has received the i-th partial secret key (Vi).

These operations are performed for each n storage units. That is, it is repeated n times.

The master storage verifies that n storage units have received the partial secret key through the blockchain and records it on the blockchain, confirming whether the storage of the encrypted distributed data has been completed. And, when completed, it reports that distributed storage of secret data has been completed.

On the other hand, in addition, the distributed storage method of data using blockchain drive technology maintains mutual database consistency when transmitting and receiving various types of information, thereby providing services quickly and conveniently.

For this purpose, the service information processing device performs the following operations.

a) First, tables storing device registration information and data of customer terminals or customer mobile terminals are provided identically to each other, and matching relationships for the tables are set and registered in advance.

b) So, when changing information in a table, the tables are synchronized according to the matching relationship.

c) And, when synchronizing the tables, the databases are consistent by diversifying information for each data type for multiple different device (or service) types.

On the other hand, additionally, this method of distributed data storage secures a connection to a customer's mobile terminal in the vicinity when transmitting various information, etc., thereby allowing the information to be transmitted quickly and easily.

To this end, the service information processing device performs the following operations.

a) First, when communicating with a registered customer mobile terminal, the service information processing device first checks whether the registered local communication network is connected, and if the local communication network is connected as a result of the confirmation, the service information processing device first checks whether the local communication network is connected, Connect as the corresponding settings administrator public account.

b) If, as a result of the above confirmation, the local communication network is not connected, the connection to the registered wireless communication network is secondarily checked. If the confirmation result is that the wireless communication network is connected, the connection is made to an individual IP address.

c) Therefore, as a result of the above confirmation, if the wireless communication network is not connected, the connection is made using the terminal identification number of the registered mobile communication network, thereby securing the connection with the customer's mobile terminal.

On the other hand, when connecting to a customer's mobile terminal in this way, an IP table is used to monitor registered IPs and manage monitoring (or logs) according to access by unauthorized persons to ensure security of the connection.

a) Specifically, for this purpose, an IP table is first configured in advance, registering the administrator public account of the local communication network and the individual IP address of the wireless communication network.

b) Then, when an alarm is provided to the administrator terminal in this way, a HELLO message of the corresponding communication network is transmitted and the next hop switch IP address in the response result is extracted.

c) Next, check the switch IP address that is the same as this next hop switch IP address in the switch neighbor connection relationship list.

d) As a result of the above confirmation, if there is a switch IP address that is the same as the next hop switch IP address, it is checked whether the corresponding administrator public account or individual IP address is also in the IP table, and thus whether an unauthorized person is connected is checked.

e) As a result of the above confirmation, if the corresponding administrator public account or individual IP address is also in the IP table, a JOIN/PRUNE message is sent, thereby connecting to the corresponding communication network.

a) When the customer inputs the desired information (or File -> plain text format), select a different secret key depending on the shape or length of the plain text,
Also, according to the size of the secret key, one of a number of different rounds is selected and executed repeatedly to obtain the ciphertext,
In addition, the function for each round applies the ARIA (Academy Research Institute Agency) encryption format, which includes round key addition, substitution layer, and diffusion layer.
b) Before performing the round key addition operation, modulate the plaintext and the secret key by first performing exclusive OR with n-1 scramblers (n is the number of storage),
c) setting the modulation information to n partial secret keys, and providing one different partial secret key to each of the n storages,
d) When the above modulation is performed, the ciphertext is obtained by repeatedly executing it as a round-by-round function including one round of round key addition operations according to the secret key size,
Each time the ciphertext is acquired (including storage), the scrambler systematically destroys the round key addition operation and the operation result is obtained in the same format as the commercial AES (Advanced Encryption Standard); A convolutional neural network-based image value judgment and distributed storage method of data using blockchain technology. In claim 1,
The first step is,
When first querying each storage for a list of available tasks through the ChainDrive format, the most previously registered task ID and distributed processing ID in the corresponding storage are searched and queried.

Meanwhile, and also the second step is,
By logging in using the password entered by the customer, you are granted access to the blockchain space.
The relevant authentication information must be configured only for one member account, and includes unique identification information including the customer's ID, electronic serial number (ESN), or mobile phone number.
The password ensures that there are at least two different passwords for one member account, and each password is differentially granted access to content stored in each storage; A convolutional neural network-based image value judgment and distributed storage method of data using blockchain technology. In claim 2,
The first step is,
A 1'-1 step of providing identical tables for storing customer terminal and device registration information and data, and presetting and registering matching relationships for the tables;
When information in a table is mutually changed, a 1'-2 step of synchronizing the tables according to the matching relationship; and
When synchronizing the table, steps 1'-3 of matching databases by diversifying information for each data type for a plurality of different devices or service types; Including,

After the fourth step above,
A fifth step of notifying the fact that information has been saved to the registered customer's mobile terminal; It further includes,
The fifth step is,
When notifying information to the customer's mobile terminal, first check whether the registered local communication network is connected, and if the local communication network is connected as a result of the confirmation, the system connects as a setting administrator public account corresponding to each different administrator work location. Step 5-1;
A 5-2 step of secondarily checking whether a registered wireless communication network is connected if the local communication network is not connected as a result of the verification, and connecting to an individual IP address if the verification result is that the wireless communication network is connected;
As a result of the confirmation, if the wireless communication network is not connected, the connection is made using the terminal identification number of the registered mobile communication network, so a 5-3 step of securing the connection with the customer mobile terminal; Including,

In step 5-2,
Step 5-2-1 of pre-configuring an IP table registering the administrator public account of the local communication network and the individual IP address of the wireless communication network;
When providing a notification to the customer's mobile terminal, step 5-2-2 of extracting the next hop switch IP address in the response result by sending a HELLO message of the corresponding communication network;
Step 5-2-3 of checking the switch IP address that is the same as the next hop switch IP address in the switch neighbor connection relationship list;
As a result of the confirmation, if there is a switch IP address that is the same as the next hop switch IP address, it is checked whether the corresponding administrator public account or individual IP address is also in the IP table, so 5-2- to check whether an unauthorized person is connected. Step 4; and
As a result of the confirmation, if the corresponding administrator public account or individual IP address is also in the IP table, a JOIN/PRUNE message is sent, so step 5-2-5 of connecting to the corresponding communication network; A convolutional neural network-based image value judgment and distributed storage method of data using blockchain technology.
