Referring to FIG. 1 , a semiconductor transaction system according to an embodiment of the present invention includes a plurality of supplier terminals 100 , consumer terminals 200 , and a server 300 . For reference, in the present invention, a supplier is a supplier that produces and supplies semiconductors, and a consumer is a consumer who wants to purchase semiconductors from the supplier.

Provider terminal 100 is a terminal used by the provider, PC (Personal Computer), notebook computer, mobile phone (mobile phone), tablet PC, navigation (navigation), smart phone (smart phone), smart watch (smart watch), Smart TV (smart TV), PDA (Personal Digital Assistants), etc. may be used.

The server 300 is configured to be wirelessly connected to the supplier terminal 100 and the consumer terminal 200 , and when the supplier terminal 100 and the consumer terminal 200 access the server 300 , the supplier and the consumer It may be configured to provide an interface over the web for convenient use of the system.

For example, the server 300 includes an Internet service unit, and the Internet service unit is configured so that the provider terminal 100 and the consumer terminal 200 are connected on the web, and the supplier and consumer can conveniently use the system on the web. may be configured to provide an interface.

The server 300 may be configured to include a communication unit 310 and a storage unit 320 for the above operation, and the communication unit 310 may include any configuration that enables wired/wireless communication, and storage The unit 320 is a component in which various data and information are stored, and various data and information transmitted by the provider terminal 100 and the consumer terminal 200 may be stored. In addition, the server 300 may be configured to include a control unit 330 capable of controlling the operation of the server 300 itself, the communication unit 310 and the storage unit 320 .

And in the present invention, the server 300 includes a data collection unit 340 for collecting semiconductor product related data; and a block generating unit 350 for generating a block according to the input of the plurality of provider terminals 100; based on the data collected by the data collecting unit 340 and the information recorded in the block and a control unit 330 that determines whether the semiconductor product is genuine or not. That is, in the present invention, while the control unit 330 is in charge of overall control, it is possible to determine whether the semiconductor product is genuine or not based on the data collected by the data collection unit 340 and the information recorded in the block.

The operation of the semiconductor authenticity determination system using block chain and big data according to the present invention will be described.

First, semiconductor product related data may be input through the plurality of provider terminals.

And the data collection unit 340 may be configured to collect the data recorded in the barcode or the data recorded in the QR code provided through the plurality of provider terminals (100).

In addition, the semiconductor product-related data includes the production year, manufacturing region, shipping country, shipping agency, Pb-free, halogen-free, component characteristics, vacuum state, packing date, shipping date, QC inspection date, firmware version, quantity , may be configured to include at least one of a product name, a serial number, and a LOT number.

Such semiconductor product-related data may be recorded in a barcode provided through the plurality of supplier terminals 100 or recorded in a QR code.

That is, in the present invention, the data collection unit 340 is the production year, manufacturing region, shipped country, shipped agency, Pb-free, halogen-free, component characteristics, vacuum state, packing date, shipment date, QC inspection date, Firmware version, quantity, product name, serial number, and LOT number can be collected extensively.

The extensive data collected in this way can assign a unique classification code to the supplier terminal that has input the data, and classify the barcode label type based on the classification code.

By classifying and classifying barcode labels for each semiconductor manufacturer by such a configuration, it is possible to collect a wide range of data and to distinguish by semiconductor manufacturer.

In the present invention, it is possible to operate using a block chain system, and the block generating unit 350 may be configured to generate a block according to an input of the provider terminal 100 .

For example, when a supplier terminal 100, which is a terminal of a semiconductor manufacturer, transmits a corresponding signal to the server 300 while shipping a semiconductor product, the block generating unit 350 may generate a block for the corresponding semiconductor product. have. The blocks generated in this way are connected in the form of a chain, and whenever a predetermined step is performed, they are connected in the form of a chain and can be utilized as a block chain system.

For example, when a semiconductor company called A performs a foundry, the provider terminal 100 of company A transmits a block generation signal to the server 300, and the block generation unit 350 generates a block according to the foundry process. can Then, back-end chip production may proceed. When company B performs back-end chip production, data for the process may be recorded in a block. At this time, blocks can be connected in a chain form.

The assembly test may then proceed, and if the assembly test is performed by Company C, data about the corresponding process may be recorded in the block. At this time, the block can also be connected in the form of a chain.

For reference, referring to FIG. 2 , in the present invention, a block may include a block header and a block body, and the block header may include a version, a block hash of the previous block, a block creation time, and a verification value.

At this time, the version can be the version of the corresponding block chain system, the block hash of the previous block is the block hash value of the previous block, the block creation time means the time when the corresponding block was created, and the verification value is the block hash value of the block. It is a factor to determine whether it is valid. When determining whether to conclude a transaction using the verification value, if the verification value is smaller than a predetermined value, it can be determined that the transaction is a valid execution, and the block hash value calculated by using the verification value as one of the input values is smaller than a specific number When the value is to lose, it may be determined that the transaction is a valid transaction.

The block body may include the above semiconductor information and other information. The semiconductor information may include data on various processes such as a semiconductor foundry, back-end chip production, and assembly testing.

In addition, since the block according to the present invention is added in the form of a block chain, the block hash is included. The block hash serves as an identifier of the block, and may be calculated by applying a hash function such as the SHA256 hash function, and may be configured to have a numeric value of 32 bytes.

Such semiconductor information is stored in the form of a block, the block is added in the form of a block chain, and can be distributed and stored in nodes connected to a network including the supplier terminal 100 , the consumer terminal 200 and the server 300 . .

Therefore, it becomes practically impossible for suppliers and consumers as well as third parties to arbitrarily modify or change the data stored in the block, and the reliability of the system can be greatly improved.

Based on such reliability, it may be possible to determine the authenticity of a semiconductor inventory product.

For example, the control unit 330 compares the data collected by the data collection unit 340 with information recorded in the corresponding block, and the data collected by the data collection unit 340 matches the information recorded in the block. In this case, the semiconductor product may be determined as a genuine product, and if the data collected by the data collection unit 340 and information recorded in the corresponding block do not match, the semiconductor product may be determined as a fake product.

Also, in the present invention, when a semiconductor-related process is switched from one company to another, a new block for verifying it can be created and managed.

For example, with respect to a semiconductor product called X, when a company A performs a predetermined process and company B performs another process, the terminal of company A (which may be one of the supplier terminals 100) and company B Each of the terminals (which may be one of the provider terminals 100 ) may be configured to transmit a process switching signal to the server 300 .

In this case, the process change signal transmitted by the terminal of the company A may include data on the process that has already been performed and data on the process to be performed in the future. In addition, the process change signal transmitted by the terminal of the company B may include data on the process that has already been performed and data on the process to be performed in the future.

The server 300 compares the data included in the process change signal transmitted by the terminal of the company A and the process change signal transmitted by the terminal of the company B with each other, and when the corresponding data match, the block generating unit 350 generates a new block in the process You can create transition blocks.

Then, if the process is switched from company B to company C, as above, the terminal of company B (which may be one of the provider terminals 100) and the terminal of company C (which may be one of the provider terminals 100) are each a server and send a process switch signal to 300 .

Also, similarly, the process change signal transmitted by the terminal of the company B may include data on the process that has already been performed and data on the process to be performed in the future. In addition, the process change signal transmitted by the terminal of the company C may include data on the process that has already been performed and data on the process to be performed in the future.

At this time, since the process change signal transmitted by the terminal of the company B includes data on the process of the company A that has been carried out in the past, the control unit 330 finds the process change block that has already been created, and then converts the process change block into a chain form. can be connected and managed.

With such a configuration, basic semiconductor information may be recorded in a general block and implemented as a chain system, and information on process change may be recorded and managed in the process change block.

In the present invention, the control unit 330 may be driven to determine the authenticity by comparing the data recorded in the process switching block with the data collected by the data collecting unit 340 when determining whether the product is genuine, if necessary.

In the present invention, since the control unit 330 performs very many roles, it may sometimes be overloaded. In this state, it is necessary to reduce the operation rate of the control unit 330 . When determining whether genuine or not, the operation efficiency of the control unit 330 can be improved by comparing the data collected by the data collection unit 340 only for process conversion blocks having a relatively small amount of data, instead of searching for all general blocks.

Also, in the present invention, a plurality of provider terminals 100 may access the server 300 to register providers. Supplier registration is to register the type, quantity, and unit price of a semiconductor owned by a supplier or a semiconductor that the supplier can produce. The supplier connects to the server 300 using the supplier terminal 100 and then registers the semiconductor or supplier that the supplier owns. You can register the type, quantity, and unit price of semiconductors that can be produced.

Thereafter, the consumer terminal 200 may access the server 300 , select at least one of the registered suppliers, and transmit a request for quotation for semiconductor supply. For example, the consumer may access the server 300 , view registered suppliers or a list of registered suppliers, and select a supplier that has the type and quantity of semiconductors he/she wants or can produce. When the consumer selects a supplier in this way, the consumer may transmit a request for quotation for semiconductor supply to the server 300 through the consumer terminal 200 , which is his/her terminal. The quotation request signal may include information on the type, quantity, and unit price of the semiconductor desired by the consumer.

After the consumer transmits the quotation request signal through the consumer terminal 200 , the server 300 transmits the quotation request signal to the selected supplier terminal 100 , and the selected supplier sends the quotation request signal from the server 300 . is transmitted through the consumer terminal 200 . Then, the selected supplier may generate a quotation corresponding to the quotation request signal through the supplier terminal 100 , which is its own terminal, and transmit it to the server 300 . The quotation may include information on the type, quantity, and unit price of the semiconductor included in the quotation request signal.

According to an embodiment of the present invention, the supplier may generate a quotation in response to the consumer's quotation request signal on the web through the supplier terminal 100 and transmit it to the server 300 .

When the server 300 receives the quotation, it transmits the received quotation to the consumer terminal 200 . In addition, when the consumer receives the quotation through the consumer terminal 200 , it may transmit an order request signal corresponding to the quotation to the server 300 through the consumer terminal 200 . The order request signal may include information on the type, quantity, and unit price of the semiconductor included in the quotation.

The server 300 transmits the order request signal to the selected supplier terminal 100 , and the selected supplier receives the order request signal through the supplier terminal 100 . After receiving the order request signal, the supplier (that is, the selected supplier) can supply the semiconductor corresponding to the order request when receiving the order request signal through the supplier terminal 100, and the semiconductor is supplied to the consumer from the supplier. Through this process, the transaction for semiconductors between the supplier and the consumer can be completed.

As such, when the semiconductor is supplied from the supplier to the consumer, the selected supplier may transmit a transaction completion request signal to the server 300 through the supplier terminal 100 . And when the consumer terminal 200 receives the transaction completion request signal through the server 300 , the consumer checks whether the semiconductor corresponding to the order request is supplied, and a transaction completion confirmation signal through his or her consumer terminal 200 . may be transmitted to the server 300 .

Also, when the server 300 receives the transaction completion confirmation signal, the semiconductor transaction system according to an embodiment of the present invention may store transaction completion confirmation data for confirming that the transaction is completed. In this case, the server 300 may store the transaction completion confirmation data in the storage unit 320 , and unlike this, a separate DB for storing the transaction completion confirmation data may be configured to be included in the server 300 .

In addition, in the semiconductor transaction system according to an embodiment of the present invention, the server 300 accumulates and stores the transaction completion confirmation data, analyzes the accumulated transaction completion confirmation data, and a plurality of supplier terminals 100 and consumer terminals 200 ) can be configured to transmit

Also, according to an embodiment of the present invention, a plurality of provider terminals 100 transmit a provider authentication request signal to the server 300, and the server 300 indicates that the authentication condition included in the provider authentication request signal satisfies a predetermined condition. When the provider authentication confirmation signal is generated, it may be configured to be transmitted to a plurality of provider terminals 100 . This allows only certified suppliers to supply semiconductors, thereby securing the reliability of transactions to consumers.

According to an embodiment of the present invention, as an authentication condition included in the supplier authentication request signal, at least one or more of a business registration certificate, official agency documents, certificate documents, and details on company evaluation may be included as an authentication condition, and the server 300 performs supplier authentication As a predetermined condition for generating the confirmation signal, at least one of a business registration certificate, official agency documents, certificate documents, and details on company evaluation may be included.

Also, according to an embodiment of the present invention, when the consumer selects at least one of the registered suppliers and transmits a request for quotation for semiconductor supply, the block may be generated.

The block generator 350 is configured to add the block to the block chain when the consumer terminal 200 receives the transaction completion request signal through the server 300 and then confirms that the semiconductor corresponding to the order request is supplied by the consumer. can

For example, when a transaction between one supplier and one consumer is completed, the consumer first selects at least one of the registered suppliers and transmits a quotation request signal for semiconductor supply to the server 300 through the consumer terminal 200 . Then, the block generating unit 350 may generate a block. In this case, the generated block may record information about the request for quotation of the consumer.

Then, when the supplier transmits the quotation to the server 300 through the supplier terminal 100 , information on the quotation may be added and recorded in the generated block.

Then, when the consumer transmits an order request signal to the server 300 through the consumer terminal 200, information on the order request signal may be added and recorded in the generated block.

Then, when the provider transmits a transaction completion request signal to the server 300 through the provider terminal 100, information on the transaction completion request signal may be added and recorded in the generated block.

Then, the consumer transmits a transaction completion confirmation signal to the server 300 through the consumer terminal 200, and information on the transaction completion confirmation signal may be added and recorded in the generated block. When information on the transaction completion confirmation signal is added in this way, the block generating unit 350 may add the block to the block chain. At this time, when the block generating unit 350 adds a block to the block chain, it may determine whether the transaction is a valid transaction (ie, whether the block is a valid block). Such determination may be made in the block generator 350 or in the controller 330 .

In this way, if the transaction is valid, the block is added to the block chain to continue, and if the transaction is invalid, the block can be discarded without adding the block to the block chain.

According to an embodiment of the present invention, it may be configured so that only authorized participants can access the block, not anyone who accesses the block. If the block is configured so that anyone can access it, the speed of adding blocks may be unnecessarily fast, which may make the block chain unnecessarily long, which in turn may lead to deterioration of the system's performance. In the present invention, it is possible to prevent system performance degradation by preventing unnecessary block addition speed by being configured so that only authorized participants can access the block.

In addition, according to an embodiment of the present invention, it is configured so that only approved participants can access the block and can have the same form as a private block chain. An attempt to add a block may be attempted by judging it as a fastening, and such an attempt may cause a problem in which the entire system collapses.

However, according to an embodiment of the present invention, at least one of the plurality of provider terminals 100 and consumer terminals 200 transmits a permission request signal including a unique identification code to the server 300, and the server 300 is configured to transmit the permission approval signal to the participant terminal that has transmitted the permission request signal in which the unique identification code does not overlap, thereby preventing any one supplier or consumer from securing a plurality of nodes to prevent the above problems in advance. can

In order to prevent any one participant from securing a plurality of nodes, when the permission request signal is transmitted by at least one of the plurality of provider terminals 100 and consumer terminals 200, the server 300 is It may be configured to generate one public key corresponding to the identification code, store the public key only when the public key does not overlap, and transmit the permission approval signal to the terminal that has transmitted the permission request signal. In this case, the server 300 may be configured to generate a private key corresponding to the public key and decrypt it through an RSA public key encryption algorithm.

In addition, the semiconductor transaction system according to the present invention may proceed with a vote to determine whether the transaction is valid, and each node connected to the network may be configured to exercise one vote.

It may be configured to determine that the transaction is valid when more than half of the voting result votes to be a valid transaction for determining whether the transaction is valid. At this time, each of the plurality of provider terminals 100 and consumer terminals 200 operates as one node, and only the terminal receiving the permission approval signal can be configured to exercise the voting right.

For example, when a semiconductor transaction is made by two participants (one supplier and one consumer) and the block generating unit 350 generates a block corresponding to the transaction, it is determined whether the block is valid. , it can be determined by voting on whether the transaction conclusion is valid.

At this time, both the provider terminal 100 and the consumer terminal 200 that have received the permission approval signal may be configured to become voters, and may be configured so that only voters can vote by performing a separate voter registration procedure. At this time, since the server 300 is also one node included in the network, it may be configured to become a voter.

For example, if the provider terminal 100 and the consumer terminal 200 that have received the permission approval signal are configured to be voters, the sum of the provider terminal 100, the consumer terminal 200, and the server 300, that is, the node When more than half voted that the transaction was valid based on the total sum of

If the transaction is determined to be valid, the block is added to the block chain, and if the transaction is not determined to be invalid because a majority is not obtained, the block is discarded.

According to the present invention, semiconductor information is stored in block form, blocks are added in block chain form, and distributed and stored in nodes connected to a network including the supplier terminal 100 , the consumer terminal 200 and the server 300 . can be

Accordingly, it becomes practically impossible for suppliers and consumers as well as third parties to arbitrarily modify or change data stored in blocks, thereby greatly improving the reliability of the semiconductor transaction system according to the present invention.
