An operating server and its operating method for providing a safe phone service using a QR code without exposing personal information by granting a communication permission level according to the nickname {OPERATING SERVER FOR PROVIDING A SAFE PHONE SERVICE USING QR CODE WITHOUT EXPOSING PERSONAL INFORMATION BY GRANTING A COMMUNICATION AUTHORITY LEVEL ACCORDING TO NICKNAME AND ITS OPERATION METHOD}

The present invention relates to a phone service, and more specifically, to an operation server and method of operating the same for providing a safe phone service using a QR code without exposing personal information by granting a communication authority level according to a nickname.

As information and communication technology develops, mobile terminals capable of online two-way communication have become widely available to most consumers.

For this reason, mutual phone calls are made using the phone number assigned to the mobile terminal, but the side effects that occur as the phone number for communication is exposed to the outside world are increasing.

For example, if the phone number is displayed or written on a business card, shopping mall, car, etc., it is used as a marketing tool by a third party and continuous marketing contact is received, or as personal information for a third party who has never provided the phone number, as a means of transaction. This can also happen.

In addition, as an individual's phone number is indiscriminately used for various illegal loans or other illegal purposes, the individual's anxiety is increasing, resulting in voice phishing and other types of financial and psychological damage.

As such, because phone numbers are treated as important personal information in modern society, there is a need for a way to make phone calls and other online communications without exposing the phone number, which is a piece of personal information.

The purpose of the present invention to solve the above problems is to provide an operating server and operating method for providing a safe phone service using a QR code without exposing personal information by granting a communication authority level according to the nickname.

In order to achieve the above object, the present invention provides an operating server for a safe phone service using a QR code.

The operating server includes at least one processor; and a memory storing instructions that instruct the at least one processor to perform at least one operation.

The at least one operation may include receiving, from the first user terminal, a second unique value and a second nickname indicated through a QR code identified in the first user terminal; Verifying the validity of the QR code using the received second unique value and the second nickname; Identifying a network address of a second user terminal using the second unique value of the validated QR code; transmitting a call request message to the second user terminal using the identified network address; and receiving a call acceptance message from the second user terminal, and creating an online communication channel between the first user terminal and the second user terminal in response to receiving the call acceptance message.

The at least one operation may include, before receiving the second unique value and the second nickname from the first user terminal, a first nickname set by a first user of the first user terminal from the first user terminal. It further includes receiving, assigning a first unique value to the first user terminal, and registering the first user using the first nickname and the first unique value.

The at least one operation may include receiving a modification request message for the second nickname from the second user terminal; Verifying the validity of the second unique value corresponding to the second user terminal that transmitted the modification request message in response to the received modification request message; and checking whether the validated second unique value is matched with the second nickname and stored in a matching table, and matching the second nickname confirmed to match the second unique value in the matching table. It further includes an operation of modifying the matching table.

The at least one operation includes, after verifying the validity of the QR code, adding the second nickname indicated by the QR code to the friend list of the matching table as a friend for the first nickname. Includes more.

The step of verifying the validity of the QR code includes obtaining the communication authority level of the second nickname indicated through the QR code, determining a unique value generation method according to the obtained communication authority level, and generating the determined unique value. The validity of the QR code is verified using the method.

When using the operating server and operating method for a safe phone service using a QR code according to the present invention as described above, online communication can be easily performed simply by recognizing the QR code without exposing various personal information including phone number. there is.

In addition, since a communication channel is created using only QR code-based nicknames and unique values and this supports online communication between terminals, personal information about terminal users is not stored in the operation server 100, and communication Data transmitted and received, such as voice or text, is also transmitted through the P2P method and is not stored on the operating server, so security and confidentiality can be guaranteed.

Figure 1 is a conceptual diagram for explaining the operation of an operation server for a safe phone service using a QR code according to an embodiment.

Referring to FIG. 1, the operation server 100 for a safe phone service using a QR code includes a first user terminal 200 owned by a first user who wishes to contact a second user online and a second user. A safe phone service can be provided by linking with the second user terminal 300 owned by the user.

The first user terminal 200 is a terminal of a user who attempts to contact using a QR code (QR) disclosed by another person (referred to as the second user throughout the specification) and is a nickname registered to the user of the first user terminal 200. is the first nickname, and the unique value assigned to the first user terminal 200 may be referred to as the first unique value.

The second user terminal 300 is a second user terminal that generates a QR code and discloses it to the outside. The nickname registered to the user (second user) of the second user terminal 300 is the second nickname, and the second user terminal 300 is the second user terminal. The unique value assigned to the user terminal 300 may be referred to as a second unique value.

In one embodiment, the first user terminal 200 may identify a QR code (QR) generated by the second user using the second user terminal 300. To this end, the first user terminal 200 may have a built-in camera capable of capturing images, and when a QR code (QR) is captured using the built-in camera, the first user terminal 200 may capture images. You can identify the QR code (QR).

When the corresponding QR code (QR) is identified, the first user terminal 200 can connect to the operation server 100 by running the application indicated by the identified QR code (QR).

At this time, if the application specified in the QR code (QR) is not installed on the first user terminal 200, the first user terminal 200 can access the URL (Uniform resource locator) indicating the installation address of the application. You can. The first user terminal 200 can install the application by downloading the installation file of the application from the connected URL and executing the installation file through the first user's operation input.

When the first user terminal 200 is connected to the operation server 100, the first user terminal 200 encrypts the unique value and nickname indicated by the identified QR code (QR) and transmits it to the operation server 100. You can.

In one embodiment, the unique value is a value uniquely assigned by the operation server 100 to the second user terminal 300 and may be generated as a random value (hereinafter, a first unique value generation example). In this case, separately from the unique value, the IP address or MAC address of the second user terminal 300 may be matched with the unique value and additionally stored in the matching table.

In addition, the nickname is a unique name registered in the operation server 100 for the second user, who is a user of the second user terminal 300, and is a name that uniquely identifies the second user by replacing the second user's phone number. It can be utilized.

In one embodiment, unique values may be generated using nicknames. For example, a unique value can be generated by converting the nickname using a preset conversion process (hereinafter, a second unique value generation example). Specifically, the unique value can be generated by converting the nickname using a hash function.

In another embodiment, the unique value may be the IP address or MAC address of the second user terminal 300, or a unique identifier previously assigned to the terminal in the product manufacturing stage (hereinafter, a third unique value generation example).

In another embodiment, the unique value is a combination of at least one or more of the IP address of the second user terminal 300, the MAC address, and a unique identifier previously assigned to the terminal in the product manufacturing stage, and a preset conversion tool. It may be a value converted using (hereinafter, fourth eigenvalue generation example). Here, the conversion tool may be a hash code generation tool. In a specific implementation example, the operation server 100 binarizes the IP address of the second user terminal 300, the MAC address, and the unique identifier previously assigned to the terminal in the product manufacturing stage, and then binarizes the IP address and MAC address of the second user terminal 300 into 3. Among the values, the binarization unit size is matched by adding a padding value (for example, 0) to the smaller values based on the value with the largest binarization unit size, and the binarized IP address and MAC address are XORed with each other. The logical result is generated by ANDing the operation result with the unique identifier given to the relevant terminal in advance at the product manufacturing stage, and the generated logical result is converted using a known hash function to create a unique value. can be created.

In one embodiment, the operation server 100 initially generates and manages a unique value for the initial user as an example of generating a first or second unique value, and when the usage history of the user is accumulated, the communication permission level of the user is changed. You can generate a unique value by applying the unique value generation example according to and use it to create a QR code.

When receiving the encrypted unique value and nickname, the operation server 100 decrypts the received unique value and nickname to identify the unique value and nickname, and uses the identified unique value and nickname to check the validity of the QR code (QR). can be verified.

When the validity of the QR code (QR) is verified, the operation server 100 identifies the network address (e.g., IP address or MAC address) of the second user terminal 300 using the unique value of the QR code, and , a call request message can be transmitted to the second user terminal 300 using the identified network address.

At this time, the call request message may include a first nickname preset for the first user who is the user of the first user terminal 200.

The operation server 100 may receive a call acceptance message from the second user terminal 300, and in response to receiving the call acceptance message, the first user terminal 200 and the second user terminal 300 An online communication channel can be created between

Here, the online communication channel is a P2P communication channel between the first user terminal 200 and the second user terminal 300, and may include at least one of a voice communication channel, a video communication channel, and a chat communication channel, but is limited thereto. It doesn't work.

For example, the operation server 100 may support a phone number-based voice call between the first user terminal 200 and the second user terminal 300 in response to receiving a call acceptance message. For example, the operation server 100 obtains a phone number corresponding to the nickname of the second user terminal 300 based on the matching table, encrypts the obtained phone number, and transmits it to the first user terminal 200. , the received phone number can be decrypted using an application running on the first user terminal 200, and a voice call can be requested to the second user terminal 300 using the decrypted phone number.

Examples of the first user terminal 200 and the second user terminal 300 include a desktop computer, a laptop computer, a laptop, a smart phone, and a tablet PC capable of communication. (tablet PC), mobile phone, smart watch, smart glass, e-book reader, PMP (portable multimedia player), portable game console, navigation device, digital camera ( digital camera), DMB (digital multimedia broadcasting) player, digital audio recorder, digital audio player, digital video recorder, digital video player, PDA ( Personal Digital Assistant), etc.

In this way, the operation server 100 according to an embodiment of the present invention discloses the QR code (QR) previously generated by the second user to the outside offline and transmits it to the outside through the first user terminal 200 of the first user. The first user can support online communication with the second user simply by recognizing the corresponding QR code (QR).

Accordingly, it may be possible for the first user and the second user to communicate with each other online without any personal information, including the second user's phone number, being exposed to the first user.

FIG. 2 is a block diagram showing the functional portion of an operation server for a safe phone service using a QR code according to FIG. 1.

Referring to FIG. 2, the operation server 100 uses a user register 101 that registers a user using a nickname set by the user, a nickname set by the user, and a unique value assigned to the user's user terminal. A QR code generator 102 that generates a unique QR code for the user, a validation unit 103 that verifies the validity of the QR code by verifying the unique value, and at least one individual matched to the user's nickname It may include a matching table management unit 104 that indicates information.

The user registration unit 101 may register nicknames of the first user and the second user in conjunction with the first user terminal 200 of the first user and the second user terminal 300 of the second user.

Specifically, the user registration unit 101 receives the first nickname set by the first user from the first user terminal 200, assigns a first unique value to the first user terminal 200, and 1 The first user can be registered using the nickname and the first unique value. Here, 'registration' may refer to the operation of matching the first nickname and the first unique value and storing them in the internal storage of the operation server 100.

The user registration unit 101 receives a second nickname set by the second user from the second user terminal 300, assigns a second unique value to the second user terminal 300, and stores the second nickname and the second unique value. A second user can be registered using a unique value.

The QR code generator 102 may receive a QR code creation request from the second user terminal 300. The QR code generator 102 may generate a QR code unique to the second user using the second unique value and the second nickname assigned to the second user terminal 300.

For example, a QR code may indicate a second unique value and a second nickname. Additionally, the QR code may indicate a running command for a pre-designated application, an installation access address for the application, or communication permissions allowing contact with the second user.

The validity verification unit 103 can verify the validity of the QR code. For example, when the QR code is photographed by the first user terminal 200 and transmitted to the operation server 100, the validity verification unit 103 can verify the validity of the QR code.

In one embodiment, the validity verification unit 103 may verify the validity of the QR code using the nickname and unique value indicated by the QR code.

When the unique value is a value uniquely assigned by the operation server 100 to the second user terminal 300 and is generated as a random value (hereinafter, first unique value generation example), the validation unit 103, The presence or absence of the unique value and nickname is checked by referring to the matching table in which the unique value and the nickname are matched. When the unique value and nickname are confirmed in the matching table, the validation unit 103 checks the unique value and the corresponding QR code. can be determined to be valid.

When the unique value is generated using a nickname (hereinafter, a second unique value generation example), the validation unit 103 generates a unique value using the nickname of the QR code, and stores the generated unique value in the QR code. When the validity of the unique value is verified by comparing it with the unique value, and the validated unique value and the nickname of the QR code are confirmed in the matching table, the validity verification unit 103 may determine that the corresponding QR code is valid.

If the unique value is the IP address or MAC address of the second user terminal 300, or a unique identifier previously assigned to the terminal in the product manufacturing stage (hereinafter, third unique value generation example), the validation unit 103 communicates with the second user terminal 300 to obtain an IP address, MAC address, or a unique identifier previously assigned to the terminal in the product manufacturing stage, and compares the obtained information with the unique value to determine the validity of the unique value. is verified, and if the validated unique value and the nickname of the QR code are confirmed in the matching table, the validity verification unit 103 may determine that the corresponding QR code is valid.

The unique value is a value obtained by combining at least one or more of the IP address of the second user terminal 300, the MAC address, and a unique identifier previously assigned to the terminal in the product manufacturing stage and converted using a preset conversion tool. In this case (hereinafter referred to as the fourth unique value generation example), the validation unit 103 communicates with the second user terminal 300 and uses the IP address, MAC address, or unique identification previously assigned to the terminal in the product manufacturing stage. Obtain the symbol, use the obtained information to generate a unique value in the same way as the unique value generation described above, compare it with the unique value of the QR code to determine if it is the same, and if they are the same, determine that the validity of the unique value has been verified. , when the validated unique value and the nickname of the QR code are confirmed in the matching table, the validity verification unit 103 can determine that the corresponding QR code is valid.

The validity verification unit 103 may determine which unique value generation method among the first to fourth unique values to verify the validity of the QR code according to the communication authority level, which will be described later.

For example, the validity verification unit 103 can verify the validity of the QR code in a manner corresponding to the fourth unique value as the communication authority level is higher, and as the communication authority level is lower, the validity of the QR code can be verified in a manner corresponding to the first unique value. You can verify the validity of the QR code using this method. (That is, the second eigenvalue has a higher communication authority level than the first eigenvalue, the third eigenvalue has a communication authority level higher than the second eigenvalue, and the fourth eigenvalue has a higher communication authority level than the third eigenvalue. It can be set to .)

To this end, the validity verification unit 103 acquires the communication permission level of the nickname indicated through the QR code, determines a unique value generation method according to the obtained communication permission level, and uses the determined unique value generation method to generate the QR code. The effectiveness of can be verified.

The matching table management unit 104 may create a matching table that matches a nickname with a unique value assigned to a user terminal of the nickname, and periodically update and modify the created matching table.

The matching table is a data table that matches registered nicknames and unique values and can be stored in advance in internal storage.

The matching table management unit 104 may create a matching table by matching the registered nickname and additionally matching the unique value with the corresponding phone number of the user terminal.

Here, the phone number of the user terminal matched in the matching table can be used to support phone number-based voice calls rather than voice communications based on mobile communication data, including LTE, among voice communication channels.

The matching table management unit 104 receives a modification request message for a specific nickname from a user terminal, verifies the validity of a unique value corresponding to the user terminal that transmitted the modification request message in response to the received modification request message, You can check whether the validated unique value matches the corresponding nickname and is stored in the matching table, and the nickname that is confirmed to match the unique value in the matching table can be modified and stored in the matching table. For this purpose, the modification request message may include a nickname after modifying a specific nickname. Through this, the user of the user terminal can edit the nickname at any time, and by simply editing the nickname, future contacts can be easily blocked through the QR code generated through the existing nickname.

The matching table management unit 104 may manage the matching table by adding the nickname indicated by the validated QR code as a friend for the first nickname of the first user who photographed the QR code.

Specifically, the matching table management unit 104 searches the matching table for the first unique value of the first user terminal 200 that captured and transmitted the QR code, and creates a friend list of nicknames that match the searched first unique value ( Alternatively, it may be referred to as a contact list) can be created in a matching table, and a nickname indicated by a validated QR code can be added to the created friend list.

The communication channel creation unit 106 uses the nickname added to the friend list at any time at the request of the user terminal having the corresponding friend list, and obtains the unique value matched with the nickname by referring to the matching table, and obtains the unique value obtained. A communication channel can be created between the user terminal corresponding to the value and the user terminal whose nickname has the corresponding friend list.

Through this, the advantage is that contact or marketing services such as various online consultations and meetings (chat), courier and quick delivery services, car purchase consultation, finding elderly people with dementia, finding lost items, and finding dogs are possible without exposing phone numbers through the friend list. there is.

The operation server 100 may further include a communication permission management unit 105 that sets and manages communication permissions of users whose nicknames are registered.

The communication authority management unit 105 can monitor the usage status according to the nickname stored in the matching table and the unique value of the user terminal, and set the communication authority level for each nickname.

For example, the communication authority management unit 105 may count the number of changes to the nickname that matches a specific unique value in the matching table, and set the communication authority level higher as the number of changes increases. In other words, the more times a nickname is changed, the lower the possibility of the user contacting other users, and the higher the communication permission level is set, considering that the user has a high level of security requirements.

The communication authority management unit 105, for each nickname in the matching table, records the number of times a communication channel was created with another user, the number of times the creation of a communication channel was rejected, and the number of nicknames of other users for whom a communication channel was created (here, communication with the same nickname) If the channel occurs multiple times, the number of nicknames exceeds one and is not counted), the more times a communication channel is created, the higher the communication permission level is set, and the more times the creation of a communication channel is rejected, the higher the communication permission level is. If you set it low and the number of nicknames of other users for whom communication channels are created is high, you can set the communication permission level low as a user contacts a lot of unspecified people.

At this time, the greater the number of times a communication channel is created with other users, the more the user is actively communicating with other users. Such users can be viewed as a positive factor up to an appropriate number of times, so the communication permission level is set high. It is desirable to do so, but if there are too many, the user may contact unwanted users, so it may be desirable to lower the communication permission level again.

Considering these circumstances comprehensively, the communication authority management unit 105 can determine the standard value of the communication authority level according to Equation 1 below.

In Equation 1, TL _nick is the reference value of the communication permission level of the nickname user (nick), cm is the variance of the number of times all nickname creation users created communication channels with other users, and cavg is the number of times all nickname creation users created communication channels with other users. is the average of the number of times a communication channel was created with other users, cc is the number of times the user with that nickname created a communication channel with other users, cd is the number of times the user with that nickname was denied the creation of a communication channel, and cs is the number of times the user with that nickname was denied the creation of a communication channel with other users. and is the number of nicknames of other users for whom a communication channel was created, k1 is a threshold value that imposes a penalty on the number of communication channel rejections, and k2 is a threshold value that imposes a penalty on the number of nicknames of other users for which a communication channel was created. . The lower k1 and k2 are set, the lower the overall communication authority level can be managed, and can be set by the administrator.

When the standard value of the communication authority level is calculated, the communication authority management unit 105 divides the distribution of the calculated standard values for each nickname into preset stages (for example, four stages) in order from high to low. And from the level corresponding to the lowest value, the value of the communication permission level is assigned one by one from 1 to the level corresponding to the highest value (e.g. level 4). The communication permission level value (e.g. between 1 and 4) The value corresponding to the natural number of can be determined.

The operation server 100 creates a communication channel between the second user terminal 300 with the second nickname indicated in the QR code and the first user terminal 200 with the first nickname that photographs and transmits the QR code. It may further include a channel creation unit 106.

At this time, the QR code may indicate a plurality of nicknames and unique values corresponding to each of the plurality of nicknames. In this case, the communication channel creation unit 106 is between the second user terminals of each of the plurality of second nicknames indicated in the QR code and the first user terminal 200 of the first nickname that captured and transmitted the QR code. You can also create a many-to-one communication channel. Even when the QR code indicates a plurality of nicknames and unique values, the above-described explanation regarding validation of the QR code, etc. can be equally applied.

The communication channel creation unit 106 creates a communication channel using only a QR code-based nickname and unique value and supports online communication between terminals through this, so personal information about the user of the terminal is stored in the operation server (100). ), and data transmitted and received during communication, such as voice or text, is also transmitted in a P2P manner and is not stored on the operation server 100, so security and confidentiality can be guaranteed.

Figure 3 is a diagram showing a service screen provided by the operation server for the safe phone service using the QR code according to Figure 1.

Referring to FIG. 3, you can see an exemplary screen of the safe phone service provided by the operation server 100.

Specifically, the operation server 100 can receive the name of a communication channel from a user terminal connected to the operation server 100, and create a communication channel for the user terminal with the input name.

At this time, the communication channel is a P2P communication channel between the first user terminal 200 and the second user terminal 300, and includes a voice communication channel (VOICE CHAT), a video communication channel (VIDEO CHAT), and a chat communication channel (FILE CHAT) may be included.

Additionally, the operation server 100 may support the function of transmitting and receiving data files to each other through a chat communication channel (FILE CHAT).

The operation server 100 may receive a nickname (NICK) input from the user of the user terminal and register the input nickname.

In addition, the operation server 100 uses the nickname (NICK) provided from the user terminal and the unique value of the user terminal to create a QR code (QR ID as shown in FIG. 3) uniquely assigned to the nickname (NICK) and unique value. -CARD) can be created.

The operation server 100 can generate a shared link for the generated QR code, and when the generated shared link is requested from the user terminal, the image of the QR code generated through the shared link is displayed on the screen. It can be transmitted to the user terminal and output from the user terminal.

Meanwhile, in Figure 3, only the most basic functions are shown by way of example, but it is not limited thereto and should be construed as being capable of providing various other functions described throughout the specification.

Figure 4 is a diagram illustrating a method of managing communication permissions through a QR code according to an embodiment.

Referring to FIG. 4, the QR code generator 102 may indicate, in addition to the nickname and unique value described above, the number of times contact is allowed, whether friend registration is permitted, and the communication permission level to allow contact. To this end, the QR code generator 102 receives and stores the number of contacts allowed, whether friend registration is permitted, and the communication permission level for contact in advance from the user terminal requesting QR code creation, and when receiving the QR code creation request. You can create a QR code so that the QR code indicates the number of contacts allowed, whether friend registration is allowed, and the communication permission level to allow contact.

The allowed number of contacts is the limit number of times to create a communication channel with the nickname indicated through the corresponding QR code, and the communication channel creation unit 106 exceeds the permitted number of contacts indicated by the corresponding QR code and If a communication channel is created between a user with a nickname different from the indicated nickname, the creation of a communication channel using the corresponding QR code can be stopped.

In addition, the matching table management unit 104 checks whether friend registration indicated by the validated QR code is permitted, and only when friend registration is permitted, matches the nickname indicated by the QR code to the corresponding QR. You can manage the matching table by adding the nickname of the user who took the code as a friend.

Specifically, the matching table management unit 104 searches the matching table for the unique value of the user terminal that captured and transmitted the QR code, and creates a friend list (or may also be referred to as a contact list) of nicknames that match the searched unique value. You can create a matching table and add a nickname indicated by a validated QR code to the created friend list.

The communication channel creation unit 106 checks the communication permission level indicated by the validated QR code and determines the communication permission level granted to the nickname that matches the unique value of the user terminal that provided the QR code. If the decision is made and the determined communication authority level exceeds the communication permission level allowed for contact, a communication channel can be created.

Figure 5 is a diagram illustrating the hardware configuration of an operating server according to an embodiment.

Referring to FIG. 5, the operating server 100 stores at least one processor 110 and instructions that instruct the at least one processor 110 to perform at least one operation. May include memory 120.
