Device for changing caller ID using encryption algorithm {DEVICE FOR CHANGING CALLER INDENTIFICATION USING ENCRYPTION ALGORITHM}

The present invention relates to a device for changing a calling number using an encryption algorithm, and more particularly, to a device for changing a calling number using an encryption algorithm capable of changing a phone number sent from a user terminal when accessing the user terminal.

In today's situation where smartphones are common, many people check company emails with smartphones or access company intranets, NAS, cloud, etc. to conduct company business.

In general, a mobile terminal such as a smart phone of a mobile communication subscriber has only one phone number. If you want to use two phone numbers for one mobile terminal for personal reasons, subscribe to the two-number service provided by the mobile operator and receive a virtual number as an additional phone number from the mobile operator. Separate phone numbers and use them individually.

On the other hand, in the case of Korea, the time the fire engine leaves the garage in the situation where it is recognized as receiving a 911 report (National Fire Classification It is recommended that the total time from the time of dispatch) to the time of arrival at the site should be less than 5 minutes. This is because the 'flash over' phenomenon, in which the flame explodes due to the accumulated heat after 5 minutes, occurs and the fire reaches its peak.

In other words, the golden hour of fire suppression is 5 minutes, and if 5 minutes have elapsed, there is a risk of enormous damage such as human casualties due to the expansion of combustion. Currently, when a fire is dispatched, golden hour is frequently missed due to illegal parking on a back road or in a curved place.

In addition, if an official using a personal cell phone requests the movement of an illegally parked vehicle, the personal information of the official is leaked, and accident reports or inquiries may be requested through the personal cell phone, causing disruption to work. The situation is that

Therefore, there is a need for a device that can easily notify an emergency situation by changing a caller number while protecting personal information when making an emergency dispatch of a public service performer using a terminal of the public service performer.

Prior to the description of the encryption algorithm according to an embodiment of the present invention described above, the user terminal 10 to which this embodiment is applied will be described.

The user terminal 10 is a portable device supporting a wired/wireless communication function, and may be a smartphone, a tablet PC, or the like. In this embodiment, the software 11 is installed in the user terminal 10, and the software 11 may include a first mode and a second mode. The first mode and the second mode can be selectively changed, and it is possible to switch from the first mode to the second mode by a mode switching signal to be described later.

The first mode is a mode in which the user terminal 10 uses the basic number as the calling number, and the second mode is a mode in which a number different from the basic number becomes the calling number. Here, the basic number refers to the user's phone number assigned by the telecommunication company, and a number different from the basic number refers to numbers such as 112 and 119 displayed when making a call or sending a text message to the owner of an illegally parked vehicle. Hereinafter, a number different from the basic number is referred to as an emergency number.

On the other hand, the software 11 installed in the user terminal 10 to enable switching between the first mode and the second mode calculates the first operation value. The first operation value allows only an authorized user to switch to the second mode and use the user terminal 10 together with a second operation value to be described later, and the user terminal 10 and the calling number change device using this encryption algorithm ( 1000), it is a configuration to check whether there is a match between them.

The connection unit 100 is configured to protrude to a specific length for connection/insertion to an external connection terminal or insertion hole of the user terminal 10 . The present embodiment and the user terminal 10 directly perform data communication through the connection unit 100 . That is, the first operation value of the software 11 , the SIM chip information, the mode switching signal, and the like are performed when the connection unit 100 is connected to the user terminal 10 . The connection unit 100 may be an earphone jack or a 5pin, 8pin, or c-type terminal.

The security unit 200 is configured so that only an authorized user can change the calling number through the first operation value. A certificate is installed in the security unit 200 . This certificate may be issued by a certification authority that has an authentication server. In this embodiment, normal operation is possible only when this certificate is valid.

The security unit 200 may be provided with a smart card (such as a micro SD card). Smart cards are one of the most secure storage media (to store keys and important data for cryptographic operations), and since cryptographic operations are performed on a hardware basis, the confidentiality and integrity of communication data can be guaranteed.

As described above, the first operation value is calculated in the software 11, and the first operation value of the software 11 is stored in the certificate of the security module in advance, which is referred to as a second operation value.

The first operation value and the second operation value may be a Secure Hash Algorithm (SHA). The secure hash algorithm used by the first operation value and the second operation value is a collection of related cryptographic hash functions.

The security unit 200 stores a serial number. That is, in response to the plurality of user terminals 10, a plurality of calling number change devices 1000 using the encryption algorithm according to the present invention are also provided, and different serial numbers are given so that each security unit 200 can be distinguished. and this serial number is stored in the security unit 200 .

The encryption unit 300 is configured to prevent information of the user terminal 10 from being leaked through an encryption algorithm. The encryption unit 300 receives the first operation value from the software 11 and receives the second operation value and the serial number from the security unit 200 .

The encryption unit 300 has a predetermined encryption algorithm, and through this encryption algorithm, the first operation value and the second operation value, and the vehicle number or photo file, location information, etc. received from the user terminal 10 are encrypted. The encryption algorithm encrypts the above-described information by using the information of the security unit 200 . Specifically, each security unit 200 is assigned a serial number, and each security unit 200 encrypts using the assigned serial number. Encrypted information is called code information.

The decoder unit 400 may identify information on the SIM chip included in the user terminal 10 . For example, the decoder unit 400 may obtain user information and caller number information stored in the SIM chip.

The processing unit 500 transmits the code information and the serial number to the authentication server. The serial number is not included in the code information. That is, since the serial number is a tool used by the encryption unit 300 for encryption, it is not encrypted. In other words, the serial number is unencrypted information.

The authentication server receives the code information and the serial number from the processing unit 500 and decrypts the encrypted code information. The authentication server decrypts the code information by using the information of the security unit 200 . The tool that the authentication server uses to decrypt is the serial number. That is, the serial number is a tool used by the encryption unit 300 to encrypt information and a tool used to decrypt code information.

The authentication server decrypts the code information, and when the first operation value and the second operation value match, it is determined that the user terminal 10 and the calling number change device 1000 using the encryption algorithm according to the present embodiment match each other do. That is, when the first operation value and the second operation value match, it is determined that the corresponding smart phone and the calling number change device 1000 using the encryption algorithm are connected, and an authorized person sets the user terminal 10 to the second It decides that you want to use it by switching to the mode. If the first calculated value and the second calculated value are different from each other, it is determined that a device for changing the calling number that does not match the user terminal 10) is connected, which may mean loss or the like.

The authentication server transmits an authentication signal to the processing unit 500 when the first operation value and the second operation value match from the decoded code information.

The processing unit 500 transmits a mode change signal to the software 11 of the user terminal 10 when receiving the authentication signal. When the mode change signal is transmitted to the user terminal 10, it is provided to be converted to the second mode when the user touches it.

The location information analysis unit 600 receives location information of the user terminal 10 . Specifically, location information or GPS information is acquired from the GPS module built into the user terminal 10 . In addition, the work area data is stored in advance in the location information analysis unit 600 . The business area data means the business area of the user who uses the calling number change device. Accordingly, by comparing the work area data received from the user terminal 10 with each other, the processing unit 500 transmits the code information and the serial number to the authentication server only when the user is within the work area. This is to prevent abuse of authority by excluding the possibility of users using it outside of work.

The memory unit 700 is configured to store a communication record generated after mode change. For example, when an outgoing signal is transmitted from the user terminal 10 to the receiving terminal 20, the memory unit 700 provides information on the time, location, and the receiving terminal 2, which are information on the transmission time of the outgoing signal. It is possible to store the recipient number, which is information. Alternatively, when the user terminal 10 transmits a text message to the receiving terminal after the mode change, the message information may be stored in the memory unit 700 .

Meanwhile, the processing unit 500 transmits the vehicle number or photo file to the authentication server upon receiving from the user terminal 10 in which the software 11 is driven. If a user encounters a problem, such as an illegally parked vehicle interfering with an emergency response, contact the vehicle owner. However, if the contact information of the owner cannot be confirmed in the vehicle, the vehicle may be photographed by inputting the vehicle number into the software 11 or through a photographing function provided in the software 11 . The input vehicle number or photographed picture is transmitted to the processing unit 500 , and the processing unit 500 transmits it to the authentication server.

The authentication server is provided with a vehicle number and a database in which contact information of the owner corresponding to the vehicle number is previously stored. In addition, the authentication server may receive the photo file from the user terminal 10 to read the license plate information of the vehicle included in the photo file. When the authentication server confirms the vehicle number or reads the vehicle number information from the photo file, the authentication server transmits the contact information of the owner from the corresponding information to the processing unit 500 .

The processing unit 500 receives the contact information and transmits it to the software 11 , and when the mode switching signal is received together, it is transmitted to the software 11 together.

In this case, when the user touches it, it is converted to the second mode and at the same time makes contact with the corresponding contact information.
