7 is a process flow diagram illustrating the operation of the vehicle license plate management system using RFID according to an embodiment in order.

As shown in FIG. 7 , the system of one embodiment first collects monitoring information by being installed for each of a plurality of different places in the video surveillance device 100 . In particular, when collecting such monitoring information according to an embodiment, information of the corresponding reader is radiated as monitoring information from an antenna unit interlocking with the built-in RFID reader, and external RFID information is converted into an input signal of the reader.

And, in this case, each RFID license plate is installed on a vehicle passing through each place. These license plates have a built-in RFID module to write vehicle information corresponding to each of a number of different vehicle types according to user definition including license plate form and color. On the other hand, additionally, vehicle information may be added with a printed QR code separately. That is, vehicle information is added and provided in correspondence with each of a plurality of different vehicle types according to user definition including the license plate form and color with the above code.

Meanwhile, the VMS 200 interlocks with the video monitoring device 100 and the RFID license plate unit at a remote location, and monitors vehicle information and information for each location as RFID information of the RFID license plate unit by the video monitoring device 100. Information is collectively collected and displayed and managed.

Specifically, the VMS 200 operates as follows.

1) First, vehicle information and illegal acts of the owner and vehicle-related information (including license plate information) are set and registered for each of a number of different vehicle types.

And, in this case, the illegal acts include occupying a vehicle lane, driving on a red light, driving in the opposite direction, and violating a forbidden lane.

2) Next, when the vehicle information and monitoring information are collected, vehicle license plate information is recognized from the vehicle information, and the recognized vehicle license plate information and monitoring information are combined and matched to determine whether or not the setting constitutes an illegal act.

3) As a result of the above determination, if it does not fall under the setting illegal act, the normal state is maintained, and if it falls under the setting illegal act, it is reported to the registration reporting center.

So, through this, when monitoring a vehicle, one embodiment solves the lack of existing basic information from the customer's demand analysis information, sharing operation for registration and submission work, prevention of identification forgery, management of obscured or damaged license plates, and Provides seamless on-site law enforcement, etc.

As described above, an embodiment first includes management and operation for basic information registration, and, for example, builds a registration/report management operation plan (form and operation, etc.) make it convenient based on In this case, various registration modes are provided for simple vehicles such as motor vehicles, suitable vehicles, and industrial vehicles, for example, motorbikes and bicycles, for each of various types of vehicles.

In addition, regarding the license plate sharing operation, specifically, the built-in RFID chip and QR code are printed so that information on the necessary vehicle can be opened according to demand.

In addition, for quick and convenient on-site law enforcement, it is solved by monitoring violations of video surveillance and license plate recognition through RFID. And, in addition, violations include, for example, occupancy of a vehicle lane, driving on a red light, driving in the opposite direction, violation of a prohibited lane, etc., thereby obtaining off-site evidence of these matters.

Therefore, through this, when monitoring a vehicle, one embodiment solves the lack of existing basic information from the customer's demand analysis information, sharing operation for registration and submission work, prevention of identification forgery, management of obscured or damaged license plates, and Provides seamless on-site law enforcement, etc.

On the other hand, additionally, this configuration allows for more effective recognition by performing object recognition from the following method when monitoring in this way.

a) First, in the case of monitoring an object in this way, if there is a setting object to be monitored in the corresponding information, the object is set in a setting format for each corresponding monitoring object for each of a number of different monitoring locations or objects corresponding to each monitoring object type It is recognized based on its unique structure/shape.

In this case, the base of the structure/shape is performed by a simple vehicle such as a motorbike or bicycle type for each vehicle type, and includes appearance, location, and movement characteristics.

b) Therefore, when the corresponding object is recognized, location information of the recognized object is extracted.

c) Therefore, through this, the location information of the corresponding object is provided to the registration management information processing device.

d) Here, the basis of the structure/shape is as follows.

1) In other words, looking at the characteristics, first, the corresponding appearance is defined for each of a number of different object types.

2) Also, in order to add such external information, a specific external appearance is selected and separately registered by contents including color, shape, and type, and provided as learning information.

And, the format is as follows.

1) That is, when monitoring the object, if there is manager setting information that includes the object, it is recognized that the information includes the appearance, location, and movement.

2) Additionally, when monitoring the object, a method of classifying and learning by different place types is determined based on information including appearance, location, and motion information corresponding to each different object type in the monitoring information. Meanwhile, as in the past, the basic object recognition operation is the same, and a description thereof is omitted here.

3) Next, a dataset representing features of information including appearance, location, and motion is extracted for each of a number of different places and object types.

4) Then, by using the extracted data set, the properties of the information, including appearance, location, and movement, are determined for each different method.

5) So, the determined information is regularly processed.

6) Based on the normalized information, properties of information including appearance, location, motion, etc. are set for each method.

Through this, independent variables for recognizing objects for each of a plurality of different places and object types and dependent variables for each place and object type are respectively set.

7) Accordingly, the information set above is used as learning and training data.

Additionally, these formats are also:

First, since the attribute state is slightly different for each situation, for example, normal times and sparsely populated situations, or busy and complex situations, different methods are created for each situation. And you can make this method for each place, or you can set a standard and make it into several groups. This makes it possible to determine the appropriate method according to the characteristics of the information.

In addition, when information is received to make a method in this way, there are cases where a large number of information is not collected due to errors in equipment, etc., or an outlier is detected, and the information must be removed. So, after creating a basic information set through this, add properties for additionally necessary information.

In addition, if some information is not collected due to the occasional disconnection of information, the information is removed.

So, next, valid properties are determined for each method, and independent and dependent variables are determined after normal values are created.

On the other hand, additionally, when objects are re-recognized in this way, objects to be monitored are determined differently according to the purpose of monitoring for each location, thereby making object recognition and management smoother.

To this end, this configuration processes objects suitable for the place according to the monitoring purpose, type of monitoring location, and monitoring target from registration information set by differently responding to the monitoring purpose, type of monitoring location, and monitoring target for each of a number of different places. By doing so, object recognition and the like are made easy.

For example, the purpose of surveillance is general surveillance and protection, surveillance of high-crime areas, intensive surveillance, etc., and the surveillance places are also general surveillance places, high-crime surveillance places, and surveillance places such as passages/structures. Additionally, in this case, the object to be monitored is determined differently according to the purpose of monitoring and the type of the monitoring place so as to facilitate object recognition.

On the other hand, in addition to this, in the method according to another embodiment, when an object is re-recognized in this way, each of the above-described devices, that is, a video monitoring device, a VMS, a management information processing device, etc. has the same registration information and monitoring information, deal with it quickly

a) To this end, first, a number of different registration information including device registration information such as a video surveillance device, a VMS, a management information processing device, etc., and a table storing monitoring information are equally provided, and a matching relationship for the tables is additionally added. Register in advance.

b) Then, when the corresponding information is changed in the video surveillance device and the VMS, the information in the table is identically changed according to the matching relationship to keep the information consistent between the devices.

c) Additionally, in case of keeping information consistent among these devices, matrix processing of each I/O port configuration for each of a number of different VMS, etc. from the set I/O port format is made multidimensional.

Therefore, whenever such information is kept consistent, information input/output is performed in multiple ways by collectively performing a change operation for each different VMS or the like from the I/O port configuration.

On the other hand, this configuration enables the administrator to smoothly receive information from the following method by securely receiving information from the video surveillance device in a cryptographic manner or providing it to the management information processing device, that is, the administrator, when monitoring is performed in this way.

That is, in this method, when information is first collected or provided, for example, n pieces of distributed information are created by using the corresponding secret key and exclusive OR feature for each number of monitoring devices or managers to collect or deliver information.

For example, video surveillance devices are classified according to each different location or type, or according to the purpose of monitoring. In addition, the management device is also a management information processing device (remote ground), a manager terminal, and a management information processing device at the work site.

Therefore, n partial secret keys are generated using this information, and encrypted distribution information and partial secret keys are stored in each of the n partial keys, thereby encrypting. In this case, the distribution information is also classified according to the number of each device.

Briefly explaining this background, as terminals become high-performance/high-capacity, the importance of protecting and managing important data inside the terminal is emerging.

In order to protect and manage such important data, a method of encrypting important data of a terminal and storing them in an external storage device for backup has been conventionally used.

However, when important data is stored in one external storage device, a problem in which important data is easily leaked may occur if the storage device is hacked.

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

On the one hand, in particular, and also, in this case, the method of inputting an arbitrary initial value and secret key is blocked by using scramble, thereby performing distributed storage more effectively.

To this end, first, in the case of encryption in this way, information is encrypted from the encryption configuration below and provided to the corresponding device.

In addition, the encryption configuration is as follows.

a) In other words, when receiving information to be monitored, a different secret key is selected according to the shape or length of the plain text based on the AES (Advanced Encryption Standard) encryption method.

In addition, cipher text is obtained by repeatedly executing one of a plurality of different rounds selected according to the size of the secret key.

In addition, the function for each round applies ARIA (Academy Research Institute Agency) encryption format including round key addition, permutation layer, and spreading layer.

b) Therefore, before performing the round key addition operation through this, modulation is performed by first performing an exclusive OR with n-1 scramblers (n is each number) from the plaintext and the secret key.

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

d) Therefore, when the modulation is performed in this way, the cipher text is obtained by repeatedly executing a round-by-round function including round key addition operation of one round according to the size of the secret key.

And, whenever the cipher text (format) is obtained, the scrambler systematically disappears in the round key addition operation, and the operation result is obtained in the same format as commercial AES.

On the other hand, in addition to this point, in the case of encryption in this way, the distributed storage method utilizes the prior art as another example to perform distributed storage from the following configuration, thereby enabling effective distributed storage in other ways.

For example, in this configuration, n-1 scrambles are first made, that is, a secret key is formed by subtracting one from the number of objects, and n pieces of distributed information are created using the secret key.

More specifically, a t-1 order random polynomial (f(x)) with a constant term as secret information is selected, and a value from 1 to n is given to x of the t-1 order random polynomial (f(x)) By substituting, n variance information can be created. In this case, t represents the number of pieces of distributed information required to recover secret information.

Then, a specific secret key is constructed.

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

Then, this information can be set as n partial secret keys, and one different partial secret key can be transmitted to each of the n objects.

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

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

Therefore, prior to transmitting the encrypted distributed information, a process of authenticating whether n objects are legitimate users may be performed.

On the other hand, for reference, if this method is encrypted in this way, the process of restoring the distributed and stored information will be described here.

First, when a request for recovery of secret information is received, encrypted distributed information is received from at least t number of administrators among n objects. In this case, prior to receiving encrypted distributed information, an authentication process with t objects may be performed.

And construct the secret key

For example, if a secret key is stored inside, this secret key is used, otherwise, a secret key is constructed separately. And in this case, if the secret key cannot be configured internally, the secret key can be obtained through n objects.

Obtaining a secret key through n objects involves receiving partial secret keys from n objects by authenticating with each of the n objects, and bitwise XORing all of the received n partial secret keys to obtain a secret secret. key can be generated. This method is additionally used together with the two methods described above.

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

And also, secret information is recovered using t pieces of distributed information.

To explain the secret information recovery process in more detail, the t-1 order random polynomial (f(x)) is recovered using t variance information, and the constant term of the t-1 order random polynomial (f(x)) , and the constant term can be recovered as secret information.
