Description

Code providing method using short message service, device for providing code using short message service, device for recognizing code received through short message and code that can be transmitted through short message

The present invention relates to providing and utilizing a code, and more particularly, a code using a short message service capable of providing a code using a short message service and recognizing a code included in a message received through a short message. The present invention relates to a method for providing a code, a device for providing a code using a short message service, a device for recognizing a code received through a short message, and a code that can be transmitted through a short message.

Short Message Service (hereinafter, abbreviated as 'SMS') is an additional telecommunication service that can send and receive text within 80 bytes using a mobile terminal such as a mobile phone or PDA (Personal Digital Assistants). Since the delay time between the transmission time and the reception time is low and the fee is low, the mobile communication service is the most used service after the voice call since it is commercialized.

Recently, in addition to SMS, a variety of message services have been used to transmit multimedia such as long texts, images, videos, music, etc. to a message, such as Long Message Servcie (LMS) and Multimedia Messaging Service (MMS). Because of the high cost, it is not used much like SMS.

Currently, SMS is used not only for exchanging messages between individual users but also for transferring credit card transactions of users, or for transmitting authentication numbers required for electronic payment and electronic commerce.

In addition, the SMS is also used to transmit the ticket worship information when the user reserved the ticket online using a portable terminal or a computer.

However, since the maximum size of the message (for example, 80 bytes) is set in advance as described above, the SMS must be composed within a limited range, and the issued ticket cannot be stolen by others without permission. Since authentication and security measures are required to be used only by the purchased user, conventionally, only the ticket reservation information indicating that a ticket has been reserved is transmitted via SMS, instead of directly transmitting the ticket reserved by the user.

In addition, the user who has received the ticket reservation information through the SMS should visit the place where the ticket issuing ticket is issued and display the ticket reservation information included in the SMS message to the ticket issuer, or tell the ticket reservation information and receive the ticket. There is a problem that the ticket issuing time or the ticket purchase time is wasted, and the ticket issuing personnel and resources necessary for tying the ticket to paper or plastic are wasted.

Japanese Patent Application Laid-Open No. Hei 08-185493 (named “2D code system card system” of the invention) generates a secondary base code based on a direction in which thin lines intersect a thick line, and generates the generated secondary base.

However, Japanese Patent Application Laid-Open No. 08-185493 has a two-dimensional code set (or two-dimensional code pattern) that needs to be converted into a graphic form in order to be transmitted to a portable terminal because the generated two-dimensional code is composed of a graphic form instead of a general symbol. do. Therefore, the two-dimensional code converted into a graphic form must be transmitted to the MMS because it is not possible to transmit via SMS, which has a disadvantage in that the transmission cost increases.

In addition to the two-dimensional codes disclosed in Japanese Patent Application Laid-Open No. Hei 08-185493, two-dimensional codes such as QR codes, Data Matrix codes, PDF417 codes, Maxi codes, Veri Codes, and the like are used for various tickets and coupons.

However, since the two-dimensional code as described above are all configured in the form of a two-dimensional image, the code cannot be transmitted through an SMS that can transmit only text within a predetermined byte (80 bytes). Therefore, the conventional two-dimensional code as described above has a problem in that the generation process is complicated, and because the code cannot be transmitted through SMS, a huge cost is required for the code transmission, and thus the code is not utilized in various fields.

In addition, since the conventional two-dimensional code is composed of a complex two-dimensional image, there is a high probability that an error occurs during the code recognition process, which requires a recognition device with high recognition accuracy, which increases the manufacturing cost of the recognition device. have.

The code recognizing apparatus 300 captures a ticket composed of three-dimensional codes displayed on the display device of the portable terminal 100 and performs image processing on the captured image to indicate an area where at least one three-dimensional code is located. Recognize a marker to be extracted, extract a pattern region in which at least one three-dimensional code (that is, three-dimensional code pattern) is located based on the coordinate values of the recognized marker, and then use the neural network to extract the predetermined pattern region from a predetermined number string. After converting to, it decodes the converted numeric string to recognize the 3D code, that is, the ticket and validates the recognized 3D code.

In detail, the code recognition apparatus 300 may include a camera unit 310, a pattern recognition unit 320, a control unit 330, and a display unit 340.

The camera unit 310 photographs the portable terminal 100 displaying the 3D code including the ticket information and then provides the captured image to the pattern recognition unit 320.

The pattern recognition unit 320 performs a preprocessing process on the image provided from the camera unit 310, detects a marker, and extracts a pattern region that is an area where a 3D code is displayed based on the detected marker. The pattern recognizing unit 320 divides the extracted pattern image into at least one pattern region each including a 3D code, processes the divided pattern regions, and provides them to the input of the neural network 327 to provide an input of the neural network 327. Based on the output, the pattern area is converted into a number corresponding to the three-dimensional code.

In detail, the pattern recognition unit 320 may include a preprocessing module 321, a marker detection module 323, a pattern image extraction module 325, and a neural network 327.

The preprocessing module 321 converts the color of the image provided from the camera unit 310 to an 8-bit gray scale, and then performs noise filtering on the image converted to the gray scale to reduce noise. . In this case, the noise filtering may be performed using a Gaussian Blur filter.

The marker detection module 323 receives the preprocessed image from the preprocessing module 321 and analyzes the histogram of the brightness value of the central portion of the image to determine the background color in the preprocessed image. Determine and set the boundaries for black and white in the preprocessed image.

For example, the marker detection module 323 may determine a background color by setting an area of a preset size (for example, 90x120 pixels) around a center of the image and analyzing a histogram of brightness values of the set area. have.

The marker detection module 323 sets the black and white boundaries in the image and binarizes the gray scale image to white and black based on the set boundary. In this case, since the color of the marker included in the binarized image is opposite to the background color, the marker detection module 323 presets the color of the marker by inverting the binarized image when the color of the marker is not a preset color in the binarized image. You can convert to the set color.

For example, when the preset marker color is white and the binarized image is displayed with a white background and a black marker, the marker detection module 323 inverts the color of the binarized image so that the color of the marker is preset index white. Can be converted to

In addition, the marker detection module 323 removes noise included in the image by performing an erode process on the binarized image or the binarized and inverted image so that the markers can be clearly distinguished from the image.

After binarization of the image is performed, the marker detection module 323 detects the marker. Here, the marker detection module 323 may detect a marker in an image by using a top hat filter. In addition, since the size of the marker displayed on each portable terminal 100 may be different, the 3D code recognition apparatus may detect the marker by adjusting the mask of the top hat filter from 15x15 pixels to 50x50 pixels.

The marker detection module 323 may verify the validity of the detected marker based on the characteristics of the predetermined marker. For example, the marker may be composed of three circles and a straight line connecting the first marker and the second marker may be perpendicular to each other with a straight line connecting the second marker and the third marker.

The marker detection module 323 may verify the validity of the detected marker by checking whether the detected marker satisfies the above characteristics.

When the verification of the detected marker is completed as described above, the marker detection module 323 provides the coordinate image of the detected marker to the pattern image extraction module 325.

The pattern image extraction module 325 extracts a pattern image, which is an area where a 3D code is displayed, from an image converted to gray scale by the preprocessing module 321 based on the coordinate values of the markers provided from the marker detection module 323. .

For example, in the gray scale image, the pattern image extraction module 325 includes a line connecting the first marker and the second marker with one horizontal side, and a line connecting the second marker and the third marker with one line. Extract a rectangular area composed of vertical sides.

Thereafter, the pattern image extraction module 325 divides the extracted pattern image into a plurality of pattern regions each including one two-dimensional code. Here, the number of the plurality of pattern regions may vary according to the size of the pattern consisting of a three-dimensional code. For example, if the pattern of the 3D code included in the message received through the SMS is composed of 32 (4 rows and 8 columns) 3D codes including 3 markers, the pattern image is divided into 32 pattern areas. Can be distinguished. In addition, each divided pattern region includes one three-dimensional code or marker.

The pattern image extraction module 325 divides each of the plurality of divided pattern regions into a preset number of detailed regions. Here, the number of subdivided subdivisions may be equal to the number of input nodes of the neural network 327. For example, when the number of input nodes of the neural network 327 is 25, the pattern image extraction module 325 divides each pattern region into 25 sub-regions (that is, 5x5).

The pattern image extraction module 325 obtains a color average value for each of the divided detailed regions and provides the color average value to the input of the neural network 327.

The neural network 327 may be composed of three layers of an input node, a hidden node, and an output node. The neural network 327 may include 25 input nodes, 10 hidden nodes, and 10 output nodes.

In addition, the learning of the neural network 327 may be learned through a back propagation method, and turn each pattern region except for the pattern region including the marker among the divided pattern regions to the input of the neural network 327. Can be learned by providing. In addition, the weight of the neural network 327 may be adjusted in consideration of characteristics of each of the various portable terminals to improve the accuracy of 3D code recognition.

The neural network 327 is provided with an average value for the detailed area of the pattern area and activates a value of a predetermined node among the plurality of output nodes based on the learned pattern.

That is, the pattern image is divided into pattern regions each containing one three-dimensional code, and the pattern region is divided into the same number of detailed regions as the number of input nodes of the neural network 327, and the color average value of each detailed region divided. After this is obtained and provided to the input node of the neural network 327, the neural network 327 activates any one of the output nodes provided to the input node based on the learned pattern.

The conversion of the 3D code through the neural network 327 as described above is performed on all pattern areas except the pattern area including the marker, so that the 3D code is converted into a string of numbers of a predetermined number (eg, decimal).

The controller 330 may include a decoding module 331 and a code verification module 333, and the decoding module 331 may convert ticket information converted into a string sequence by the pattern recognition unit 320 into a bit string. After the error is detected, the encrypted bit string is decrypted and provided to the code verification module.

Here, the decoding module 331 may convert the decoded bit string into data in a form that can be recognized by a person (eg, text composed of letters and / or numbers).

The code verification module 333 compares the decoded bit string provided from the decoding module 331 with a predetermined data pattern, verifies the validity of the 3D code, and then provides the verification result to the display unit 340.

Alternatively, the code verification module 333 may display the ticket verification result and the contents of the ticket converted into human-readable data through the display unit 340.

The controller 330 may control the overall operations of the camera unit 310, the pattern recognition unit 320, and the display unit 340 in addition to the decoding and code verification functions as described above.

Each 3D code 410 corresponds to a specific number as shown in FIG. 6 and may be converted into the corresponding number shown in FIG. 6 by the code recognition apparatus.

One three-dimensional code 410 may be converted to a number of a particular number (for example, decimal), the three-dimensional code pattern 400 composed of a plurality of three-dimensional code (410) Can be converted to a string of numbers. The converted string of numbers can be converted back to a bit string.

The 3D code 410 may increase the type of the 3D code 410 or increase the number of 3D codes 410 according to the type of information to be expressed.

For example, the three-dimensional code 410 is composed of any one of ┼, ┌, ┐, └, ┘, ├, ┤, ┬, ┴, ─, each three-dimensional code 410 is shown in FIG. As described above, when the number corresponds to any one of the decimal numbers, the number of information that can be represented by ten different three-dimensional codes 410 is 10 ¹⁰ .

In addition, when the ticket transmitted through the SMS message is composed of a three-dimensional code pattern 400 of four rows and eight columns, the number of three-dimensional codes 410 excluding three markers 431, 433, and 435 is 29. The number of information that can be represented is 10 ²⁹ .

Also, the markers 431, 433 and 435 may be composed of three circles. That is, the markers 431, 433, and 435 are the first marker 431 for indicating the start position of the three-dimensional code pattern 400, and the second marker for indicating the width of the three-dimensional code pattern 400 ( 433) and a third marker 435 for indicating an end position of the 3D code pattern 400, and a straight line connecting the first marker 431 and the second marker 433, and the second marker 435.

Hereinafter, the encoding process of a ticket according to an embodiment of the present invention will be described. The encoding of the ticket may be performed by the code generation module 230 shown in FIG.

For example, assuming that the information of the ticket consists of 54 bits, the code generation module 230 may add information for encrypting the ticket and information for detecting an error to be included in the 3D code pattern 400. Convert to the number of bits.

For example, if a three-dimensional code is composed of ten symbols as shown in FIG. 6 and a different decimal number corresponds to each three-dimensional code, 17 three-dimensional codes are required to represent 54 bits of information. .

Further, if the three-dimensional code pattern 400 of the ticket transmitted in the SMS message is composed of four rows and eight columns, the number of usable three-dimensional codes excluding three markers is 29. Accordingly, the three-dimensional code pattern may be composed of three markers, 17 three-dimensional codes representing code information, and twelve three-dimensional codes for encryption and error detection.

The allocation of three-dimensional code for encryption and error detection may depend on the nature of the ticket (the ticket's hackability and usage environment).

For example, if the risk of hacking on a ticket is low, the 3D code assigned to encryption can be dedicated for error detection. If the ticket usage environment is stable, the 3D code assigned to error detection can be used for encryption. Can be dedicated.

The encryption of the ticket is to prevent the ticket from being used illegally due to hacking or the like, and a public key algorithm may be used.

In addition, error detection is used to determine whether an error occurs in the decoding of a ticket, and a parity bit may be used. For example, in the ticket information composed of the bit string, the bit string may be divided into predetermined bit units, and then parity bits may be generated in the divided bit units.

In general, binary data transmission generates an error in bits. However, when decoding a ticket transmitted through SMS, an error occurs in units of three-dimensional codes. Therefore, when parity bits are directly inserted into each bit unit, a specific three-dimensional method is used. If a code recognition failure occurs, the parity bit and data are lost at the same time, and thus an error cannot be detected. Therefore, in the ticket encoding process according to an embodiment of the present invention, a plurality of parity bits generated for each of the divided bit units are separately managed without being inserted into the corresponding bit units, converted into three-dimensional codes, and then three-dimensional code patterns. Arrange at a specific location.

In addition, the 3D code added for encryption and the 3D code added for error detection in the ticket encoding process may not be arranged in the 3D code pattern sequentially, but may be arranged in an order determined by the operator to further improve security. have.

The configuration of the 3D code pattern is described as an example, and the 3D code pattern may be configured differently according to the contents of the ticket, the type of the 3D code, and the number of columns of the 3D code pattern.

5 and 6, the three-dimensional code 410 is composed of ┼, ┌, ┐, └, ┘, ├, ┤, ┬, ┴, ─, │, and the markers 431, 433 and 435 are composed of Although illustrated as an example, in another embodiment of the present invention, the three-dimensional code 410 may be composed of various letters, numbers, symbols, etc. that can be transmitted through an SMS message. In addition, the markers 431, 433, and 435 may be composed of various symbols that can be easily identified in preparation for the 3D code and the code recognition apparatus 300 can easily recognize them.

Hereinafter, a process in which a user receives a ticket through SMS and uses the received ticket will be described with reference to FIGS. 1 to 6.

First, the user accesses the code providing apparatus 200 through the communication network 150 using the portable terminal 100 or a computer, performs user authentication, and then selects any one of various tickets.

For example, when a user is issued a railway ticket, the user first selects a date to board, a boarding time, a departure station, and a boarding station, and then checks whether a seat exists. Here, the presence or absence of a seat may be provided by the ticket information providing module 220 based on a search result of the ticket issuing database 260.

When the user completes the application for issuance of the railway ticket through the above process, the ticket information providing module 220 transmits the ticket issuance information in which the boarding date, the boarding time, the train type, the seat number, and the amount are displayed. ) And firstly notify the user that the ticket issuing application is completed by transmitting the SMS message to the portable terminal 100 of the user.

Thereafter, the code providing apparatus 200 converts the information of the ticket requested by the user into a three-dimensional code, configures an SMS message, and then carries the user's hand at a predetermined time (for example, 30 minutes to 1 hour before the boarding time). Send to the terminal 100 via SMS.

Thereafter, the user displays the railway ticket received through the SMS at the time of boarding the train on the portable terminal 100 and presents it to the crew, and the crew is displayed on the portable terminal 100 of the user through the code recognition device 300 in three dimensions. The code is recognized and the validity of the three-dimensional code (ie, railway ticket) displayed on the user's portable terminal 100 is verified.
