Description

System information recognition and provision system using two-dimensional barcode using mobile phone camera {SYSTEM FOR RECOGNIZING AND PROVIDING GOODS THROUGH TWO-DIMENSIONAL BAR CODE USING CAMERA OF CELLULAR PHONE}

The present invention is a system for recognizing and providing product information through a two-dimensional bar code using a mobile phone camera, and more specifically, while having a camera that can generate and process a variety of information about the product as a two-dimensional bar code to shoot and scan the two-dimensional bar code The present invention relates to a system for recognizing and providing a product information through a two-dimensional barcode that enables a consumer to easily recognize a two-dimensional barcode through a mobile phone so that product information can be grasped in real time.

Currently, as a method of displaying information about a product, a barcode generated by a specific method by converting from a letter to a numerical value is widely used.

These barcodes are widely used throughout the world due to the convenience that codes are processed within a small space and contain various information of products. By the way, the bar code is composed of a plurality of information lines in a space mainly formed of a bar (bar) form a structure that is difficult to contain a relatively large amount of product information compared to the area through the bar. In addition, it is pointed out that the bar code coded by a specific method is not immediately interpreted on its own, so that it is difficult for the consumer to visually know the specific information of the corresponding product directly, and thus it is difficult to immediately determine whether to purchase the product.

Overcoming these issues, a new concept bar code has been published that now includes a new concept bar code called the Environment Protection & Safety (ES) code (or NS Code: New Environment Protection & Safety).

1 is a conceptual diagram illustrating a schematic state of a conventional ES code.

As can be seen from Figure 1, ES code (NS code) has a similar form to a conventional one-dimensional barcode, but inserts a new type of code, such as genetic modification confirmation code, safety test confirmation code and code number is 1 The closer it is, the higher the quality and the safer the setting is that the user can be identified by the eye.

However, such a conventional ES code has the disadvantage that the volume of the code itself is larger as the amount of information to be recorded, and also if the customer near the product may be able to check the product status directly, In order to send the ES code to other consumers by sending a mobile phone camera and sending it as an MMS, the mobile phone camera does not properly recognize the ES code or one-dimensional barcode consisting of one-dimensional (multiple line segments). There is a problem that it is often impossible.

Referring to Korean Patent Publication No. 200-0110532 "Method for identifying the production background of a product by a barcode", a technology for transmitting or recognizing such an ES code to a remote site through the Internet or mobile is published. Is composed of one-dimensional line segments, the problem is that it is difficult for mobile phone holders with typical camera resolution, that is, ES code receivers, to identify them properly when they send them to mobile quickly. In the case of purchasing a product, it is inconvenient to make an immediate product purchase decision because it cannot be immediately checked and must move to a place where Internet service is available.

Therefore, there is an urgent need for a product information recognition and provision system that emphasizes the discernment of the consumer and can transmit a large amount of information in a small capacity and transmit it conveniently and readablely to the remote consumer.

The present invention has been made to overcome the problems of the above technology, and provides a bar code containing a variety of information of the product in two dimensions as a picture information or code information having a specific form and can be read in real time through the consumer's mobile phone Its main purpose is to provide a system that maximizes the capacity of information storage and facilitates the recognition of codes and guarantees the real-time of transmission even when transmitted to remote sites.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings. The accompanying drawings are not drawn to scale and wherein like reference numerals in the various drawings refer to like elements.

2 illustrates a basic configuration of a system for recognizing and providing product information through a two-dimensional bar code using a mobile phone camera according to the present invention.

As can be seen from Figure 2, the system according to the present invention is made to confirm the various beneficial information of the product through the two-dimensional bar code displayed on the product via the mobile phone 10 based on the WIPI, Specifically, the mobile phone 10, the two-dimensional bar code management server 20, the production information server 30 is composed of.

The mobile phone 10 generally refers to a so-called integrated mobile communication terminal as well as an electronic device having a wireless communication function such as a PDA. In particular, the mobile phone 10 has a built-in camera function to scan a two-dimensional barcode printed on a product. It is based on having the ability to do so. The mobile phone 10 includes a two-dimensional barcode database 400 corresponding to the basic information 410 and at the same time scan module 110, identification module 115, identification request module 120, basic information providing module 130, a module such as the upgrade module 140 is provided.

The two-dimensional bar code management server 20 has the same function as the central control center in the system according to the present invention, the function of providing extended information other than the basic information for a specific product, as well as the extended information through the mobile phone that the consumer has If there are more than 420 product information requests, it manages and controls them and obtains additional information 430 of the product through interworking with the production information server 30 according to the situation, and groups the consumers by grouping them. Has the function of parallel management.

The production information server 30 has a function of providing detailed and specific additional information 430 in addition to the basic information 410 and extended information 420 for a specific product. It serves to provide the additional information 430 via the two-dimensional bar code management server 20 by.

Referring to the specific configuration of the system according to the present invention according to the basic configuration relationship as follows.

3 is a block diagram illustrating a detailed configuration of a system for recognizing and providing product information through a two-dimensional bar code using a mobile phone camera according to the present invention.

The system according to the present invention is a two-dimensional barcode generation module 210, two-dimensional barcode database 400, scanning module 110, identification module 115, identification request module 120, identification confirmation module 230, basic In addition to the information providing module 130, extended information providing module 220, additional information providing module 310, query list output module 240, and additionally provided with a group management module 250, two-dimensional barcode transmission module 260. Doing.

The two-dimensional barcode generation module 210 serves to generate a two-dimensional barcode that is two-dimensionally coded by various rules of the product to the individual numerical value by a predetermined rule.

The two-dimensional barcode generation module 210 according to the present invention is specifically provided in the two-dimensional barcode management server 20, and includes an information collection conversion unit 211, a picture information representation unit 212.

Two-dimensional bar code consists of two-dimensional NS (New Environment Protection & Safety) code and picture information.

4 is a conceptual diagram illustrating an example of a 2D NS code according to the present invention, and FIG. 5 is a conceptual diagram illustrating an example of picture information according to the present invention.

First, a two-dimensional NS (New environment Protection & Safety) code (two-dimensional bar code commonly referred to in the present invention), which directly affects the human body, such as food, agricultural products, etc. to ensure environmental conservation and food safety Refers to information that displays a code containing comprehensive information on the status of the product in a two-dimensional space partitioned by the x- and y-axes, and easily stores large amounts of data (up to 7,089 characters in the space). Ease of storage, simplicity of taking up relatively little space, excellent readability and decipherability of reading in any direction, and self-correcting code with error correction code for excellent identification of up to 30% damage Refers to a future information scale code that can replace the existing one-dimensional barcode. This two-dimensional NS code is mainly generated by the information collection conversion unit 211.

In addition, as can be seen from Figure 5, unlike the two-dimensional NS code, which is difficult for the consumer to read the reading and the specific contents, the picture information is a product information so that the main information of the product can be immediately seen by the eyes 2 Means information expressed as a dimensional picture.

For example, if five major indicators to be described later are displayed in a pentagon, the user can only see the quintile area of the pentagon by the color best, green, excellent, light green, normal, blue, poor, orange, or very poor. View and check product status directly, or visually check the status of each of the five major indicators (quality, performance, etc.) in the form of bar graphs and line graphs according to the size, height and color of the graph. It is. It is conceivable that such picture information is mainly generated by the picture information expression unit 212.

The information collection conversion unit 211 is based on the information of various products, including the most important information of the product information, that is, the main indicators (basic genetic modification or not, safety, environmental pollution, production method, production factor) set to five basically. Expressed as numerical information, this digitized information is stored in a two-dimensional specific area, and finally, a two-dimensional NS code is generated.

That is, one-dimensionally separated genetic modification identification code, safety inspection confirmation code, environmental pollution prevention management code, production method evaluation code, production factor evaluation code, expiration date, production date, producer's unique number, check digit, country of origin It can be understood to have a function of expressing various one-dimensional information such as codes, production region area codes, HS CODE, GHS codes, and product shipment codes as two-dimensional barcodes (two-dimensional NS codes).

The picture information expression unit 212 has a role of generating a picture of the main indicators of the product in order to be able to immediately visually check the five main indicators that can be said to be the most important information of the two-dimensional NS code.

The picture information expression unit 212 is intended to prevent the inconvenience of not being able to directly check the status of the product is displayed as a password when the two-dimensional NS code is usually visible, through which the information of a specific product is the two-dimensional The NS code and the picture information (in the present invention, the two pieces of information may be collectively referred to as 'two-dimensional barcode') can be generated separately.

The two-dimensional barcode information database 400 refers to a two-dimensional bar code information, a picture information, and a high-resolution complete two-dimensional bar code (hereinafter, referred to as a standard two-dimensional bar code) itself is constructed as a database. The database 400 is basically stored in the two-dimensional bar code management server 20 or the upgrade module 140, which will be described later to the mobile phone of the consumer by a method of storing and processing the basic information having a predetermined capacity in advance at the time of release of the mobile phone ( 10) may be stored. In addition, in order to ensure efficient distribution of data, prevention of server traffic, and real-time information checking status, the two-dimensional barcode information database 400 basically includes basic information 410 and extended information 420 according to the level of the data or the place where it is stored. , And additional information 430, which will be described later.

The upgrade module 140 is provided in the consumer's mobile phone 10 to store the 2D barcode database 400 (mainly basic information 410) in the memory of the consumer's mobile phone 10 and to manage the 2D barcodes at regular intervals. In addition to upgrading the basic information 410 in conjunction with the server 20, at this time, the consumer can select and set the product so as to select only to upgrade the basic information 410 of the product of interest.

The scan module 110 is provided in the mobile phone 10 of the consumer. In particular, the scan module 110 performs a function of scanning a two-dimensional bar code in a product into an image file through a camera embedded in the mobile phone.

That is, the scan module 110 is to shoot and scan the two-dimensional NS code or picture information printed / provided on the product to store in the mobile phone 10 or to prepare to transmit to the two-dimensional barcode management server 20 To provide.

The general one-dimensional barcode has a general shape extending in a straight line by forming a bar, and when the entire bar is taken, the resolution is reduced and it is difficult to accurately recognize the bar. In addition, the two-dimensional barcode according to the present invention not only has a built-in error correction code itself, but also has a small area, which ensures adequate resolution even with a camera function of a commercially available general mobile phone 10. This adds the advantage of shooting.

The identification module 115 is photographed by the scan module 115 by a function of the upgrade module 140 or by a comparison search method with a two-dimensional barcode database 400 (ie, basic information) previously stored in a mobile phone. It performs the function of reading two-dimensional barcode of a specific product.

As mentioned above, the identification module 115 is a two-dimensional bar code pre-stored in the mobile phone because it has a level capable of reading a two-dimensional bar code made of a small enough area only by the general functions of the currently available mobile phone camera. It is prepared to be able to check the main information of the currently scanned products in near real time only by the comparison search method.

Basic information providing module 130 is provided in the mobile phone 100, specifically, the basic information output unit 131 and the quality check unit 132.

The basic information output unit 131 analyzes the two-dimensional NS code of the product that has been identified through the identification module 115 to inform the consumer (mobile phone holder) about the five major indicators of the corresponding product, including producer information, The basic information 410 of the product, which is the information level required at a general level such as the production site information, has a function of displaying on a mobile phone display unit (liquid crystal screen) in a content format or a representation such as a picture.

In addition, the quality checker 132 reads the basic information 410 to determine whether the product has a value enough to safely purchase the corresponding product, such as a recommendation of purchase or safety recommendation according to quality check of the product, To the recommendation / deprecation, reassurance / normal / anxiety, such as in such a way to serve to express the user to the user more easily to express the basic information (410).

As such, the consumer checks only the basic information 410 for a specific product by basically equipping the mobile phone 10 possessed by the consumer with the scan module 110, the identification module 115, and the basic information providing module 130. When you want to do not need to communicate separately, such as downloading the product information by separately connecting to the two-dimensional bar code management server 20 can not only check the product information more quickly, but also does not bear a separate communication fee Has the property of providing customer convenience.

The identification request module 120 according to the present invention does not include the basic information 410 of the product on the mobile phone 10 due to the absence of the upgrade, the consumer does not properly photograph the two-dimensional bar code displayed on the product packaging, etc. When the two-dimensional barcode was not identified through the identification module 115 due to the extremely unclear resolution, the corresponding two-dimensional barcode was transmitted through the two-dimensional barcode management server 20 to download basic information 410 or additionally identified. It provides a function to request a standard two-dimensional bar code or additional information 420 having a good resolution and completeness.

Since two-dimensional barcodes have higher self-identification than one-dimensional barcodes, if the two-dimensional barcode is not identified, there may be a failure of the error correction code portion itself, a damage of the two-dimensional barcode portion at 30% or more, and a decrease in resolution. will be. In order to resolve this partial non-identification state, it is necessary to reinforce the insufficient partial non-identification problem by informing the consumer of some known information through the product.

Specifically, the identification request module 120 automatically generates an input window when a non-identifiable determination (when there is no information or does not identify itself) comes from the identification module 115 provided in the mobile phone 10, for example, a product. The name, product sales location, product serial number of the consumer directly enters through the keypad of the mobile phone 10 serves to enable the additional information created by the two-dimensional barcode management server 20 to be transmitted. This allows you to search and verify the full information of the product through additional information, such as the product name or product serial number, if the information is partially identifiable or only around the product. Provide a basis for identifying parts).

The identification confirmation module 230 is provided in the two-dimensional barcode management server 20, and provides a criterion for interpreting additional information transmitted from the identification request module 120 and interpreting a two-dimensional barcode having a low resolution. The additional information analyzing unit 231, the resolution analyzing unit 232, and the bar code replacing unit 233 are provided in order to play a role.

The additional information analysis unit 231 primarily finds a plurality of pieces of product information related thereto through a two-dimensional barcode part that can be identified by maximally interpreting a two-dimensional barcode of a corresponding product including an analysis shortage part, and secondarily, a plurality of The additional information transmitted from the identification request module 120 is used as a supplementary search criterion among the products found in dogs, and finally, the nearest or related product is finally found. ) Has a role to transmit.

The resolution analyzer 232 is provided to prepare for the case where the resolution is not identified as a decrease in resolution. The resolution analyzer 232 includes three start symbols (first shown at each corner of the two-dimensional NS code in FIG. (In the case of a QR code), since it does not contain complex codes and has a simple state, it is possible to first search for a start symbol that can be interpreted and its surroundings, and then at least After searching as a plurality of products, the secondary information has a function of selecting more related products from among a plurality of products searched through the additional information and transmitting them to a mobile phone.

The barcode replacement unit 233 does not have a precise two-dimensional barcode form because the resolution is faint, so that it is impossible to identify at the level of the mobile phone 10 in which information processing capacity is low, but the computing power is superior to the mobile phone 10. If the identification is possible in the two-dimensional barcode management server 20 extracted from the two-dimensional barcode database 400 of the two-dimensional barcode management server 20, the clear form of the corresponding two-dimensional barcode (also called a standard two-dimensional barcode database) (10) serves to transmit. The two-dimensional bar code management server 20 has a state that can already grasp the information of the product, it is also good to transmit this information to the mobile phone 10, but in this case, the communication fee burden may occur, so the pre-owned This is to transmit a two-dimensional barcode (two-dimensional barcode having a resolution guarantee state in the two-dimensional barcode database) in the form of an image file to the mobile phone 10 to be identified at the mobile phone 10 itself level.

The identification confirmation module 230 is a function and characteristics for helping to resolve the identification power in the two-dimensional barcode management server 20 dimension when the two-dimensional barcode scanned by the travel consumer has a state that can not be identified at the level of the mobile phone (10) to provide.

The extended information providing module 220 is provided in the two-dimensional barcode management server 20, when the consumer who has already confirmed the basic information 410 of the product through the mobile phone 10 requests additional detailed information, the consumer's mobile phone 10 ) Will be responsible for providing the definitive information 420 of the product, wherein the 'extension information' 420 is the five major information contained in the basic information providing module 130 provided in the mobile phone (10) In addition to the basic information 410 such as indicators, it refers to information containing extensive details such as check digits and production dates.

In detail, the information on the product obtained by analyzing the two-dimensional bar code according to the present invention, that is, the two-dimensional bar code database 400, the basic information 410, expansion according to the classification system of the information, the degree of specificity of the information The information 420 and the additional information 430 are divided.

Basic information 410 can be stored in the mobile phone 10 and the two-dimensional bar code management server 20, the five major indicators, producers, producers about the above-mentioned level of information about the state of the product roughly A piece of information that has a quality and level of grasp.

Extended information 420 is basically contained in the two-dimensional bar code management server 20, and more specific information, such as check digits, production date, rather than the basic information 410, the consumer is a two-dimensional bar code management It is possible to connect to the server 20 and use a fixed communication fee or service fee.

The additional information 430 refers to detailed information provided by the production information server 30 when there is no detailed information in the 2D barcode database held in the 2D barcode management server 20, that is, the extended information 420. For example, the production region area code, the producer's unique number, HS code, GHS code, etc. may be included, which will be provided by the additional information providing module 310 provided in the production information server (30).

Additional information providing module 310 is provided in the production information server 30, and linked to the two-dimensional bar code management server 20 to provide and record comprehensive and comprehensive information, that is, additional information 430 of the product and If there is a request for additional information 430 in the 2D barcode management server 20 (of course, such a request is generated by the consumer), the additional information 430 for the corresponding product was stored. Via the two-dimensional barcode management server 20 or the two-dimensional barcode management server 20 has a role of direct transmission processing to the consumer's mobile phone (10).

In the present invention, the information about the product, that is, the two-dimensional bar code database 400 is divided into three categories such as basic information 410, extended information 420, additional information 430 and the mobile phone 10, two-dimensional, respectively By distributing the barcode management server 20 and the production information server 30 in a distributed manner, the capacity of information stored can be efficiently distributed and managed, thereby preventing problems such as traffic occurrence or lack of storage space on the server side. Provide the characteristics.

The inquiry list output module 240 is provided in the two-dimensional barcode management server, and the related products that were inquired and requested through the two-dimensional barcode management server 20 according to a specific classification criteria such as a specific time zone and a specific product line for each specific consumer. 2D barcode itself and the corresponding information (basic information, extended information, can include all additional information) has the function to output.

Through this function, it is possible to provide a feature that allows a lot of information to be managed as needed by outputting a result that a user who has many inquiries about a two-dimensional bar code has inquired about a specific time period or a specific product.

At this time, the output can be managed by a specific printer and controlled up to the output state (output time, number of copies, etc.).

The group management module 250 according to the present invention is provided in the two-dimensional bar code server 20 to process a plurality of demanders having the same interest relationship as a specific group (group) to manage a plurality of demanders collectively while at the same time To provide a function for providing the benefit of information sharing, specifically, it consists of a group designation unit 251, information sharing unit 252, storage unit 253.

The group designation unit 251 has a role of grouping a plurality of consumers and grouping the mobile phone numbers of the grouped consumers into one and designating and storing them in the 2D barcode server 20. Specifically, recruiting consumers who will belong to a group of a on a separately prepared web site or mobile space, or a group of consumers having the same interest relationship creates a group of a while adding and withdrawing group members. It provides the function to save and manage the information according to the process. In general, a multi-person consumer who needs to designate a group may be an intermediary trader for a specific product, a consumer organization, or a group that needs to check the information of a specific product in real time. Important matters, such as changing the number of people in a group, such as withdrawal, may provide a method of determining by the majority of the masters in the group or the number of people in the group.

The information sharing unit 252 provides the extension information when a specific person in the group requests the extension information 420 (which may also include the basic information 410) of a specific product through the 2D barcode server 20. In conjunction with the module 220 has a role of transmitting not only the mobile phone 10 of the person requesting the extension information 420 for the product, but also to the mobile phone 10 of all other people in the group. Thus, the personnel in the group can check the extended information 420 of the specific product in real time not only by their own actions (information requesting actions) but also by the actions of other persons in the group.

The storage unit 253 automatically stores the extended information 420 of the specific product transmitted from the information sharing unit 252 in each mobile phone 10 of all the consumers in the group. As such, the product information of the specific product is automatically accumulated in the mobile phone by the storage unit 253, and the two-dimensional barcode database 400 of the mobile phone 10 may be updated in real time to the basic information 410 as well as the extended information 420. Can be.

That is, the information requested by several persons in the group by the function of the storage unit 253 is stored in the mobile phone 10 of the other persons in the group, so as to obtain the extended information 420 for the product of interest by itself. Since the extended information 420 can be obtained from the mobile phone 10 without having to continuously access the 3D barcode management server 20, the number of people (consumers) in the group can have a benefit of reducing communication charges.

The two-dimensional barcode transmission module 260 is provided in the two-dimensional barcode management server to provide a function to safely and identifiably transmit the two-dimensional barcode scanned by the first consumer to the second consumer, as well as the MMS of the mobile phone. When a two-dimensional barcode that can be processed as an image file can be easily transmitted by a person skilled in the art by the transmitting function, the barcode may not be easily identified by transmitting a barcode with an unclear or poor state to the two-dimensional barcode. In preparation for performing a separate function beyond simply performing the MMS transmission and reception function, for this purpose it is provided with a transmission unit 261, a status check unit 262, a standard information transmitter 263.

When the first consumer transmits the two-dimensional barcode of the specific product secured by the first consumer to the second consumer, the transmitter 261 does not directly transmit the mobile phone 10 of the second consumer to the two-dimensional barcode management server. Preferred to 20 is the transmission of the two-dimensional barcode by the first consumer.

The status checker 262 reads the two-dimensional barcode transmitted to the two-dimensional barcode management server 20 by itself and performs a function of determining whether it can be identified and whether the resolution is low.

If the two-dimensional barcode has a resolution or a state that is not enough to identify itself, a text message such as 'unidentifiable' is transmitted to the first consumer's mobile phone without transmitting the corresponding two-dimensional barcode to the second consumer. 1 It provides a role for the consumer to secure the corresponding 2D barcode again.

The standard information transmitter 263 replaces the two-dimensional bar code that is identified by the status checker 262 but is inferior in resolution to a standard two-dimensional bar code having a standard resolution stored in the two-dimensional bar code management server 20. It is responsible for transmitting the replaced standard two-dimensional barcode to the mobile phone 10 of the second consumer.

By the function of the two-dimensional barcode transmission module 260, it is possible to provide a characteristic that can transmit and share a two-dimensional barcode with a more accurate resolution between consumers.
