Description

[0001] The present invention relates to a system for selling used goods and a system for trading used goods using the same,

The present invention relates to a used goods sales system, a security information deletion system for a used article, an intermediary system for a used article, a reserve operation system, a used article management system, and a transaction system for a used article using the same.

With the establishment of the Internet based on TCP / IP (Transport Control Protocol / Internet Protocol), various communication networks are being integrated around the Internet worldwide, and the number of types of services provided on the Internet is rapidly increasing along with the surge of Internet users. In addition, according to the recent popularization of smart phones, services provided only on PCs are now being provided in various ways by providing various services by using smart phones.

Generally, the transaction structure of goods sells new products and provides A / S after a certain period of use. Since there is no recycling and recycle structure for products, There is a problem.

If a person sells a used electronic product by using a direct transaction such as a used country, a website that does not receive goods even after paying for the used electronic product, or builds the price information of the used electronic product in a database and provides information (Web Site) and application services of mobile communication devices, there is always a problem of security in the transaction such as the case where the user is sold at a low price.

Also, if you want to purchase new electronic products at the same time as you sell used electronic products, it is troublesome to purchase new products after sales by using second-hand sales site (site). Also, If there is a large demand, there is no way to cope with it, which causes a problem of lowering the customer's satisfaction.

On the other hand, it is an important asset for companies and individuals who store and manage businesses and individuals on hard disks such as servers and PCs. In particular, data stored in a storage medium such as a hard disk is very important as an asset because it contains important security data such as information on development of core technology, sales information, customer information, and personal information.

However, such important information can be easily leaked to other people through the storage medium, which is recognized as a serious problem. For example, if an employee who worked in a company returns a computer that was used at the time of leaving the company, or if a computer used by a company or an individual is sold as a used one, and the hard disk is transferred to another person, However, it is often the case that the stored data is retained or deleted, and only the location information about the data is deleted.

Since security data is often exposed to other people or other companies through a storage medium leaked to another person, it is necessary to delete a recoverable deletion file so that it can not be restored. This is because in the modern society where security data management becomes increasingly important It is very important for companies.

In addition, important information contained in storage media such as smart phones and computers sold in the discarded or used market can be restored by a general deletion method. As a result of the anxiety of the sellers, the sales or recycling of smart phones or computers It is important to make sure that the data stored on the smartphone or computer storage medium is completely erased so that the seller can use it safely.

Conventionally, many methods for deleting data stored in a storage medium have been used. However, it is difficult for the seller to confirm whether the security data of the seller has been deleted securely or to prevent the seller from worrying about leakage of security data. There is no sale of used sales.

On the other hand, the general article management structure is a structure that only manages the product name with a value such as 100 in the product name without identifying the identification tag of each product. It records detailed records of each of a number of identical products at the time of goods entry and exit, If there is a problem that can not be solved and there are a plurality of the same products, there is a problem that the products may be mixed unless the products are checked immediately after the products are repaired.

In addition, the product can be checked only through the PC's inventory management system when moving the logistics. In the logistics center, there is a case where the logistics moving line is processed and the computer input is performed. Since there are many kinds of products to be sold and the quantity that each product should have as a basic item is different, there is a problem that the basic inventory can not be adjusted frequently even though the person in charge of inventory management is a specialist. Is causing consumers to receive bad quality services with internal mistakes.

In addition, when the product is shipped at the time of shipment, there is a problem that the shipment of the product is different from the purchased product sometimes because the shipment of the product is made directly, and when the input / output quantity of the product can not be seen at a glance, a screen in the form of a dashboard There is a problem in that it is difficult to intuitively grasp the inventory and there is an insufficient problem in establishing an efficient sales strategy of the product.

8, an electronic device information deletion system 2000 according to an exemplary embodiment of the present invention includes an electronic device 210 having a storage medium 211 storing security data and deletion means 212, The electronic device 210 and the deletion management server 220 are capable of transmitting and receiving data through a communication network and are capable of transmitting and receiving security data in an electronic device including a storage medium, The file is deleted.

The electronic device 210 is collectively referred to as a device having a storage medium 211 in which data can be stored, such as a PC, a smart phone, or a tablet. The storage medium 211 collectively refers to a storage means in which security data desired to be deleted by a user is stored and includes storage means such as an HDD, an SSD, a memory, etc. stored in a computer, or a smart phone, a tablet, .

The communication network connecting the electronic device 210 with the deletion means 212 and the deletion management server 220 may be a WAN (Wide Area Network), a LAN (Local Area Network), a wireless such as 3G, 4G, It is an i-bimnet that can use a mobile communication network and provide a data service with high capacity data transmission and reception through Internet Protocol (IP) which performs such functions. It can be an All IP network which is an integrated i-bimetal network. In addition, the communication network may be one of a wired communication network, a mobile communication network, a Wibro (Wireless Broadband) network, a HSDPA (High Speed Downlink Packet Access) network, a satellite communication network and a WiFi (WI-FI) network.

The deletion unit 212 may be an erase program installed in the PC 210a when the electronic device is a PC or an erase application installed in the smartphone 210b when the electronic device is a smart phone. The deletion unit 212 includes a security class designation module 21 for setting a security level of the data file, a security data management module 22 for designating a storage location of the security data file, a secure data deletion module (23).

The security level designation module 21 determines the security level of each data file stored in the storage medium 211. In this case, the security level can be determined as a file that requires or does not have security, or it can determine the importance level such as level 1, level 2, and level 3 according to the level.

The security level assignment module 21 can determine the security level according to the file attribute predetermined by the user. At this time, the file attribute may be an extension, a creation date, an author, a file size, a password file, etc. of a file that a user has specified in advance. For example, it is possible to determine a data file requiring security for a file having a specific extension, or to designate a security level such as determining a security level according to the length of a password or the size of a file with respect to a file in which a password is generated, You can decide how you want to make a variety of assignments depending on your needs and needs.

In addition, the security level designation module 21 may be determined as a security level directly input by the user of the electronic device. For example, when storing the data file, the security class designation module 21 pops up a message for confirming whether to designate the data file as a file requiring security or a security level selection message to determine security or security level.

The security data management module 22 classifies the data file designated as data requiring security into a designated data storage location and separately stores and manages the data file. That is, regardless of the location where the user stores the data file, data requiring security is actually stored in a predetermined position. This is particularly useful when the storage medium is a solid state disk (SSD), so that only the data stored in the designated storage location can be selectively deleted or the virus can be infected.

In addition, the security data management module 22 generates a shortcut for executing the data file stored in the designated storage location, so that data requiring security is stored at a substantially designated storage location regardless of the location where the user stores the data file It is possible to increase the reliability of deletion of the security data file by blocking the storage or copying in the other space.

The secure data deletion module 23 deletes the virus-infected security data file by the data infection unit 221 to be described later, and the data deletion can be performed in various ways. In one embodiment, a method of overwriting and deleting arbitrary data in a storage location where a data file is stored may be introduced. That is, any data is overwritten on the storage medium 211 to make it impossible to restore the existing security data.

Depending on the security level set in the data file, the number of overwriting times can be automatically determined from several to several tens of times, and in some cases the user can adjust the number of overwriting times. It is preferable that the overwritten arbitrary data is overwritten in the entire storage area by overwriting the storage capacity of the secure data storage location or the storage capacity of the storage medium 211. [

As another embodiment of the secure data deletion, the data file classified into the third level is set to be overwritten by a basic security data deletion method under a certain number of times, and the second level is set to be higher than the third level security If the security data deletion method is performed, the overwriting is performed more than a certain number of times and then the encryption key deletion step is additionally set. In the case of the first level, Is performed more than a specific number of times and the encryption key deletion step is repeatedly performed several times.

However, as described later, in the present invention, the secure data deletion module 23 can reduce the number of overwriting of data because the data file requiring security is executed after infecting the virus.

The deletion management server 220 includes a data infection unit 221 for injecting a virus (Cryptovirus) using an encryption algorithm into a data file in response to a request from the deletion unit 212, a cryptographic key deletion unit 222, and a deletion authentication unit 223.

The data infection unit 221 infects and infects a data file designated by the security level designation module 21 that requires security through the communication means or a data file stored at a specific storage location by the data management module 22. Cryptoviruses can only be recovered if they have a cryptographic key to encrypt the data file and decrypt it. Unlike other viruses, in the case of cryptovirus, only information necessary for decryption is stored in the deletion management server 220.

For example, in the case of Ransomware, which is a kind of cryptovirus, the data infection unit 221 generates a public key and a private key, stores the private key, and distributes the virus storing the public key. When the virus is activated, it generates a random secret key and encrypts the data with a block cipher.

In addition to cryptovirus, other viruses can be injected. For example, a sandbox tool uses malicious code that repeatedly overwrites arbitrary data hundreds of millions of times, erasing security data, and then formatting it so that the security data can not be recovered. However, when the SSD is applied as a storage medium, if a sandbox tool is injected into the SSD and repeatedly overwritten hundreds of millions of times, there is a problem that the internal data is worn out and the security data can not be recovered. On the other hand, it is also possible to apply other kinds of malicious codes as long as it is possible to prevent the security data recovery by forcibly converting the extension of the executor file of the data.

The encryption key deletion unit 222 performs encryption key deletion. The encryption key deletion unit 222 deletes the unique encryption key that can recover the encrypted data file, thereby preventing the data file infected with the virus from being permanently restored. For example, in the case of Ransomware, it permanently deletes the private key used to decrypt the secret key or the secret key used for the block encryption to make the data file irrecoverable. The deletion of the encryption key by the encryption key deletion unit 222 may be performed by setting a time or by an instruction of a user.

The deletion authentication unit 223 transmits information confirming deletion of the data file to the requestor through communication after deletion of the security data file is completed. The deletion authentication unit 223 is provided with various security data deletion processes for verifying that the data file and the encryption key have been deleted from the data deletion module 23 and the encryption key deletion unit 222, The deletion certificate in which the disk information and the serial number are written is created. It is also possible for the person in charge to additionally write such description, and to automatically write the process of operating the deletion management server 220. An electronic signature may be written in the created deletion certificate so as to prevent forgery and falsification of the certificate.

The deletion management server 220 stores the deletion authentication details in the database 230. The user accesses the deletion management server 220 at any time via the communication network and receives a deletion certificate on the web or mobile, Can be viewed.

The deletion authentication details stored in the database 230 through the deletion management server 220 are issued to the personal PC 210a or the portable terminal 210b via the communication network and are transmitted to the personal PC 210a or the portable terminal 210b And the user can confirm the stored deletion certificate. Also, the deletion management server 220 may issue another deletion certificate in addition to the storage medium on which the secure data deletion is completed through the connector.

The deletion management server 220 is connected to the personal terminal such as the personal PC 210a and the portable terminal 210b through the communication network to receive the deletion authentication stored in the deletion management server 220 if the user desires, So that deletion history information of the storage medium can be browsed on the web.

The security level designation step S2 is a step of determining whether the security of the data file is required and the security level after the installation step S1. The security level may be determined automatically by the deletion unit 212 according to the file attribute of the data file or may be determined manually by the user upon inquiry of the security level and security level to the user upon storage of the data file.

The request step S4 is a step of requesting the deletion management server 220 to delete the security data through the communication network when the deletion of the security data is requested by the user, And requests the deletion management server 220 for virus infection using the encryption algorithm.

If the deletion of the security data is requested by the request step, the data file infection step (S5) searches the data file classified as a data file requiring security through the security level designation step (S2) Injecting the virus through the communication means and deleting the encryption key of the virus. A step of injecting a virus (cryptovirus) using a cryptographic algorithm, a random software such as a cryptovirus, a sandbox tool, a malicious code and the like into the data requiring security by the security class designation step S2.

In addition, the data file infection step (S5) includes encrypting a data file that requires security by infecting a virus, and then deleting the only encryption key that can recover the encrypted data file, thereby preventing the data file infected with the virus from being permanently recovered .

The data deletion step (S6) is a step in which the deletion means (212) deletes the infected data file. The data deletion step S6 may overwrite and delete arbitrary data in the storage medium in which the data file is stored. The number of overwriting times of several to several decades may be determined and deleted according to the security level. The data file requiring security may be deleted after the virus infection in the data file infection step (S5), thereby reducing the overwriting frequency of the data.

The method for deleting information of an electronic device according to an embodiment of the present invention further includes a step S3 of storing a data file requiring security determined by the security level designation step S2 in a predetermined storage location of the storage medium 211 can do. The data file designated by the data requiring security is classified into the designated data storage location regardless of the location where the user stores the data file and is separately stored and managed to selectively infect the virus or infect the virus easily in the data file infection step S5 It is possible to selectively delete only the data stored in the data storage location designated in S6. This is particularly useful when the storage medium is a solid state disk (SSD).

Further, the information deletion method of an electronic device according to an embodiment of the present invention may further include a deletion authentication step (S7) for deleting the encryption key of the virus and the authentication of the deleted information of the infected data file after the data deletion step (S6) . A step of transmitting to the requester information confirming deletion of the data file after the deletion of the security data file is completed; various security data deletion processes for proving that the data file and the encryption key have been deleted; a person in charge, a deletion time, Information, hard disk information, serial number, and the like.

The deletion authentication step S7 includes issuing the deletion authentication details to the personal PC 210a or the portable terminal 210b via a communication network and storing the deletion authentication details in the personal PC 210a or the portable terminal 210b And issuing and issuing another deletion certificate in addition to the storage medium on which the secure data deletion is completed through the connector.
