Hereinafter, embodiments will be described in detail with reference to the accompanying drawings.

1 is a diagram showing that values for information are determined differently according to a coordinate system.

1 (a) shows an image 110 in which information 111, 112, 113, and 114 of a plurality of parameters are stored. Within the image 110, the information 111, 112, 113, 114 for each parameter is in bar form. The information 111 for the first parameter is shorter than the information 112 for the second parameter and the information 112 for the second parameter is shorter than the information 113 for the third parameter. The information 113 for the third parameter is shorter than the information 114 for the fourth parameter.

However, the values of each parameter can not be determined accurately by the information included in FIG. 1 (a). In order to accurately determine the value of each parameter, information about the coordinate system related to each parameter as well as the information 111, 112, 113 and 114 for each parameter is required.

FIG. 1 (b) shows information 121, 122, 123, 124 about several parameters and information 125 and 126 about a coordinate system associated with the parameter. Although not shown in FIG. 1 (b), information on the scale of each coordinate axis (for example, whether it is a linear scale or a log scale) may be added to the information 125 and 126 for each coordinate system. In addition, information indicating which position of each coordinate axis corresponds to which value of the parameter (for example, information on the position of '0' or the position of '1' on the coordinate axes) may be added.

According to one aspect, the information 111 for the first parameter may be 50 pixels in the vertical direction, and the information 112 for the second parameter may be 100 pixels in the vertical direction. In addition, the information 113 for the third parameter may be 150 pixels in the vertical direction, and the information 114 for the fourth parameter may be 200 pixels in the vertical direction. As shown in FIG. 1 (b), when the coordinate systems are orthogonal to each other and linear scale, the value of each parameter may be proportional to the vertical length of the information on the pyrameter. For example, the value of the first parameter may be determined to be 50, the value of the second parameter may be determined to be 100, the value of the third parameter may be determined to be 150, and the value of the fourth parameter may be determined to be 200. [

In FIG. 1 (b), the case where the coordinate systems are orthogonal to each other is shown, but in some cases, the respective coordinate systems may not be orthogonal to each other.

FIG. 1C shows information about the coordinate systems 135 and 136 that are not orthogonal to each other, and information 131, 132, 133, and 134 about several parameters.

1C, the information 131, 132, 133, and 134 for each parameter may be in contact with the first coordinate axis 135 and the second coordinate axis 136. In this case, the decoding apparatus for determining the parameter values by referring to the information on the parameters 131, 132, 133, and 134 and the coordinate systems 135 and 136 includes a first coordinate axis 135 and a second coordinate axis 136, The intersecting point can be interpreted as a vanishing point in FIG. 1 (c), and the first coordinate axis 135 and the second coordinate axis 136 can be interpreted as lines extending from the vanishing point.

In this case, the parameters between the specific coordinate axes 135 and 136 may all be determined to be the same value. That is, even if the information 131, 132, 133, 134 of the respective parameters have different lengths, the respective parameters may be determined to be the same value.

According to one aspect, the value of each parameter can be determined by considering the location of information about the parameter in the coordinate system. As shown in FIG. 1 (c), when the information 131, 132, 133, and 134 of the parameters are located near the origin of the coordinate axis, the values of the parameters can be determined to be large values. However, if the information 131, 132, 133, 134 for the parameters are located far from the origin of the coordinate axis, the values of the parameters can be determined to be small values. 1C, the parameter values are largely determined when the parameter information 131, 132, 133, and 134 are located near the origin of the coordinate axes. However, the coordinate axes are located near the origin of the coordinate axes The values of the parameters may be determined to be small.

As shown in Fig. 1, the value of each parameter can not be determined only by information on each parameter. In order to determine the value of each parameter, information on each parameter as well as information on the coordinate system associated with each parameter is required.

Referring to FIG. 1, when a specific parameter is encrypted, information on parameters generated by encrypting the parameter can be stored or transmitted without information on the coordinate system as shown in FIG. 1 (a). Even if the information on the parameter is exposed by the hacker or the like, the hacker can not decode the information on the parameter into the parameter without the information on the coordinate system. Therefore, the parameter can be encrypted by a simple method and the security can be improved.

In addition, the value of the parameter can be determined in consideration of the color of the information about the parameter. For example, information about parameters may be encrypted with various colors such as green, yellow, and red. In this case, the information on the parameter indicated in green may be determined to have a value twice as large as the value determined in consideration of the coordinate axes, and the information on the parameter indicated in yellow may be three times the value determined in consideration of the coordinate axes . In this case, information on the parameter can be additionally encrypted using a predetermined color table, and the hacker has to grasp all of the information on the parameter, the information on the coordinate axes, and the color table to determine an accurate value of the parameter The security for the parameter is improved.

Therefore, the value of the parameter can be determined in consideration of the number of pixels constituting the information on the parameter, the position of the information about the parameter on the coordinate axis, the kind of the coordinate axis, the color of the information about the parameter,

2 is a block diagram illustrating the structure of an encryption apparatus according to an exemplary embodiment.

The encryption apparatus 200 according to the exemplary embodiment includes a first storage unit 210 and a second storage unit 220.

The encryption apparatus 200 encrypts the parameter to generate information about the parameter. According to one aspect, the encryption apparatus 200 sets a coordinate system as shown in Fig. 1 (b) or Fig. 1 (c) for encrypting the parameters. The encryption apparatus 200 determines information on the parameter from the parameter with reference to the set coordinate system.

The first storage unit 210 stores information on parameters. According to one aspect, the first storage unit 210 may store information about a parameter as an image. In this case, the number of pixels constituting the information on the parameter in the image can be determined according to the value of the information on the parameter. For example, if the value of the information on the parameter is 100, the information on the parameter may be composed of 100 pixels in the image. Or information about the parameter may occupy a length corresponding to 100 pixels in the image.

The second storage unit 220 stores information on the parameter and information on the coordinate system associated with the parameter, separately from information on the parameter. According to one aspect, information about the coordinate system can also be stored as an image. The configuration for storing the information about the parameter and the information about the coordinate system related to the parameter separately from each other will be described with reference to FIG.

FIG. 3 is a diagram showing that information on the parameters and information on the coordinate system are stored separately.

3 (a) is a diagram showing that the first storage unit 210 stores information 311, 312, 313, and 314 about the parameters in the first image 310. FIG.

3B shows that the second storage unit 220 stores information about the coordinate systems 321 and 322 related to the information 311, 312, 313 and 314 on the parameters in the second image 320 Respectively. As shown in FIG. 3, the information on the parameters can be stored in different images separately from the information on the coordinate system. In this case, the encryption apparatus 200 transmits the first image 310 including the information about the encrypted parameter to the decryption apparatus via the first path, and the second image 320 including the information about the coordinate system To the decoding apparatus through the second path. Since the hacker hacking all of the first image 310 transmitted through the first path and the second image 320 transmitted through the second path, the hacker needs to hack the information about the parameter and the coordinate system If you store the information separately, it is safer to hack outside.

The decoding apparatus receives both the first image 310 transmitted through the first path and the second image 320 transmitted through the second path to generate a third image 330 as shown in FIG. Can be generated. The decoding apparatus can determine the value of the parameter by referring to the information 331, 332, 333, 334 on the parameter and the information 335, 336 on the coordinate system. In this case, the decoding apparatus can determine the value of the parameter by referring to the number of pixels constituted by the information 311, 312, 313, and 314 about the parameter in the first image 310.

In this case, the value of the parameter can be determined in consideration of the position of the information on the parameter in the coordinate system.

According to yet another embodiment, the information about the coordinate system can be stored in the same image as the information about the parameter. In this case, the image may comprise a plurality of layers. Information about the parameters is stored in the first layer of the image, and information about the coordinate system can be stored in the second layer of the image. The configuration for storing the information about the parameter and the information about the coordinate system in the same image will be described with reference to FIG.

4 is a diagram illustrating storing information on a parameter and information on a coordinate system in an image including a plurality of layers.

The first storage unit 210 stores information on parameters in the first layer 410 of the image.

The second storage unit 220 stores information on the coordinate system in the second layer 420 of the image.

As shown in FIG. 4, when the information about the parameter and the information about the coordinate system are stored in different layers of the same image, the decoding apparatus receives only one file, The parameter values can be easily determined using the information and information about the coordinate system .

According to another embodiment, the image shown in FIG. 4 may include a plurality of layers 420, 430 that store information about a coordinate system. In this case, the second storage unit 220 stores the information on the first coordinate system related to the parameter information in the second layer 420, and the information on the second coordinate system related to the information on the parameters, And can be stored in the writer 430.

In this case, the decoding apparatus can select information on any one of the coordinate systems among the information on the plurality of coordinate systems. The decoding apparatus can determine the value of the parameter using information on the selected coordinate system.

According to one aspect, the decoding apparatus can select at least one coordinate system from information on a plurality of coordinate systems in accordance with a predetermined time or a predetermined order. If the hacker hackes the image file shown in Fig. 4 to obtain information on parameters and information on all coordinate systems, but does not know information on the time or order of selecting the coordinate system, Parameters can not be decoded. Thus, the parameters can be more strongly encrypted.

In addition, the value of the parameter can be determined by referring to the color of the information about the parameter. For example, the decoding apparatus may multiply a value determined in consideration of a coordinate axis with a value described in a predetermined color table, or additionally determine a final value of the parameter.

5 is a block diagram showing a structure of a decoding apparatus according to an exemplary embodiment.

The decoding apparatus 500 according to the exemplary embodiment includes a first reading unit 510, a second reading unit 520, and a decoding unit 530.

The first reading unit 510 reads information about the parameter. According to one aspect, information about the parameters may be stored in the image. In this case, the first reading unit 510 can calculate the number of pixels constituted by the information on the parameter on the image and read the information on the parameter.

The second reading unit 520 reads information on the coordinate system associated with the information on the parameter. Here, the coordinate system associated with the information on the parameter may be stored separately from the parameter or separately. For example, if information about a parameter is stored in the first image, the coordinate system associated with the information about the parameter may be stored in the second image.

Or information about the parameter is stored in the first layer of the image, the coordinate system associated with the information about the parameter may be stored in the second or third layer of the same image. In this case, the first reading unit 510 reads information on the parameters stored in the first layer, and the second reading unit 520 reads information on the coordinate system stored in the second layer or the third layer.

According to one aspect, in association with information on one parameter, information on a plurality of coordinate systems can be read out. For example, information about a parameter is stored in a first layer of an image, and information about a coordinate system is stored in a second layer and a third layer. In this case, the second reading unit 520 may read both the information on the first coordinate system stored in the second layer and the information on the second coordinate system stored in the third layer.

The decoding unit 530 can determine the value of the parameter by referring to the information on the parameter and the information on the coordinate system. For example, the decoding unit 530 may determine the value of the parameter by considering the position of the information on the parameter in the coordinate system. When the second reading unit 520 reads information on a plurality of coordinate systems, the decoding unit 530 obtains information on at least one coordinate system among information on a plurality of coordinate systems at a predetermined time or in a predetermined order You can choose. The decryption unit 530 can determine the value of the parameter using information on the selected coordinate system.

The decryption unit 530 can determine the value of the parameter by referring to the color of the information about the parameter. For example, the decoding unit 530 may multiply the value determined in consideration of the coordinate axes with a value described in the predetermined color table, or add the value to determine the final value of the parameter.

FIG. 6 is a flowchart illustrating a step-by-step description of the encryption method according to the exemplary embodiment.

In step 610, the encryption device stores information about the parameters. Here, the information on the parameter may be a value determined by encrypting the parameter. For example, the encryption apparatus can determine the coordinate system shown in Figs. 1B, 1C, and so on to encrypt the parameters. The encryption apparatus can determine information about the parameter by referring to the determined coordinate system. Even if the values of the parameters are the same, the information about the parameters can be changed according to the selection of the coordinate system, which has already been described with reference to FIG. 1, so that a detailed description thereof will be omitted.

According to one aspect, information about the parameters can be stored in the image. In this case, the information about the parameter may be stored in the form of an area or length on the image. The information about the parameter may be composed of pixels on the image.

In step 620, the encryption device stores information about the coordinate system associated with the information about the parameters separately from information about the parameters. According to one aspect, the information about the coordinate system may be stored in an image different from the information about the parameter.

According to another aspect, the information about the coordinate system can be stored in different layers of the same image as the information about the parameters. That is, if the information about the parameters is stored in the first layer of the image, the information about the coordinate system can be stored in the second layer of the same image.

According to another aspect, information about a plurality of coordinate systems can be stored in different layers of an image with respect to information about one parameter. In this case, the encryption apparatus may store information about the parameters in the first layer of the image, and information about the coordinate system in the second layer and the third layer.

The value of the parameter may be determined by reference to information about the stored parameter and information about the coordinate system. Since the information about the parameter is stored in the form of a pixel, the value of the parameter can be finally determined by referring to the number of pixels constituting the information about the parameter in the image. In this case, the value of the parameter can be determined in consideration of the position of the information on the parameter in the coordinate system.

When information on a plurality of coordinate systems is stored in association with information on one parameter, information on at least one coordinate system among information on a plurality of coordinate systems may be selected according to a predetermined time or a predetermined order. In this case, the value of the parameter is determined using information on the selected coordinate system. The value of the parameter is changed from information on one parameter according to a predetermined order or a predetermined time, so that the security of the parameter is improved.

In addition, the value of the parameter can be determined by referring to the color of the information about the parameter. For example, the decoding apparatus may multiply a value determined in consideration of a coordinate axis with a value described in a predetermined color table, or additionally determine a final value of the parameter.

FIG. 7 is a flowchart illustrating a step-by-step description of the decoding method according to the exemplary embodiment.

In step 710, the decoding apparatus reads information on the parameter. According to one aspect, information about the parameters may be stored in the image. In this case, the decoding apparatus can calculate the number of pixels constituted by the information on the parameter on the image and read the information on the parameter.

In step 720, the decoding apparatus reads information on the coordinate system associated with the information on the parameter. Here, the coordinate system associated with the information on the parameter may be stored separately from the parameter or separately. For example, if information about a parameter is stored in the first image, the coordinate system associated with the information about the parameter may be stored in the second image.

Or information about the parameter is stored in the first layer of the image, the coordinate system associated with the information about the parameter may be stored in the second or third layer of the same image. In this case, the decoding apparatus reads the information about the parameter stored in the first layer in step 710, and the information on the coordinate system stored in the second layer or the third layer in step 720. [

At step 720, information about a plurality of coordinate systems can be read with respect to information about one parameter. For example, information about a parameter is stored in a first layer of an image, and information about a coordinate system is stored in a second layer and a third layer. The decoding apparatus can read both information on the first coordinate system stored in the second layer and information on the second coordinate system stored in the third layer.

An embodiment in which all information on a plurality of coordinate systems is read will be described with reference to Fig.

8 is a flowchart illustrating another embodiment of the decoding method.

In step 810, the decoding apparatus can select information on at least one coordinate system among information on a plurality of coordinate systems. According to one aspect, the decoding apparatus may select information for at least one coordinate system according to a predetermined time, or in a predetermined order.

In step 730, the decoding apparatus may determine the value of the parameter by referring to information on the parameter and information on the coordinate system. For example, the decoding apparatus can determine the value of the parameter in consideration of the position of the information on the parameter in the coordinate system. When the decoding apparatus reads out information on a plurality of coordinate systems, the decoding apparatus can determine the value of the parameter using information on the selected coordinate system. If the hacker hackes the image file including both the information on the parameter and the information on the coordinate system to obtain the information on the parameter and the information on all the coordinate systems and if the information on the time or order for selecting the coordinate system is not known, A hacker can not decrypt a parameter from information about the parameter. Thus, the parameters can be more strongly encrypted.

The decoding apparatus can determine the value of the parameter by referring to the color of the information about the parameter. For example, the decoding apparatus may multiply a value determined in consideration of a coordinate axis with a value described in a predetermined color table, or additionally determine a final value of the parameter.

The method according to an embodiment may be implemented in the form of a program command that can be executed through various computer means and recorded in a computer-readable medium. The computer-readable medium may include program instructions, data files, data structures, and the like, alone or in combination.
