FIG. 1 illustrates a speech bar code conversion and recognition system according to an embodiment of the present invention. Referring to FIG.

1, a speech bar code conversion and recognition system according to an embodiment of the present invention includes a conversion device 100 for converting an audio signal including a user's voice into a bar-code image, and a recognition device 100 for recognizing the bar- (200).

The conversion apparatus 100 refers to an apparatus for converting an audio signal into a barcode image, and can perform a series of operations, for example, through execution of an application or a programmed software module.

For example, the conversion device 100 may be a smart phone, a personal computer (pc), a notebook, a tablet PC, a PDA, etc., All devices may be included.

The recognition device 200 refers to a device for recognizing a barcode image and reproducing an audio signal. Like the conversion device 100, the recognition device 200 can perform a series of operations through the execution of an application or a programmed software module.

Accordingly, the recognition apparatus 200 may be a smart phone, a personal computer (pc), a notebook, a tablet PC, a PDA, or the like, and a device capable of executing the above- Can all be included.

Meanwhile, an embodiment of the present invention proposes a recording function that can be utilized not only as a means for supplementing the legal effect of digital signatures, but also in various fields throughout society.

In order to utilize such a recording function, a separate storage (eg, CD, USB) capable of storing the recorded user voice was provided, and a method of storing the recorded user voice as a file in the storage was common.

However, in the case of the above-described method, in order to store a large number of recorded user voices, introduction and management of a storage having a large storage capacity is required. Further, in order to check the recorded specific user voice, So that it is possible to expect the inconvenience that a large amount of stored files must be retrieved one by one.

Accordingly, in one embodiment of the present invention, a method for facilitating recording and listening of user's voice in connection with the above-described recording function will be described in detail.

First, the conversion apparatus 100 performs a function of generating an audio signal.

More specifically, the conversion apparatus 100 generates an audio signal including an input user voice when a user voice is input in association with an input item of the electronic document.

At this time, the conversion apparatus 100 arranges the inputted user's voice in the audio frequency band (20 to 20,000 Hz), so that the user's voice inputted in relation to the input item of the electronic document can be audible upon reproduction of the audio signal thereafter.

However, the input items of the electronic document may further include various text information including, for example, a fingerprint written to guide the user's voice, a signature of the user, and a sentence in which the inputted user's voice is textized.

Accordingly, in generating the audio signal, the converting apparatus 100 generates the audio signal by encoding the above-described text information in the non-audio frequency band, unlike the user's voice arranged in the audio frequency band.

In addition, the conversion apparatus 100 performs a function of converting an audio signal into a barcode image.

More specifically, when the generation of the audio signal is completed, the conversion apparatus 100 converts the generated audio signal into a barcode image so that the recognition apparatus 200 can recognize the converted barcode image and reproduce the audio signal.

Here, the audio signal may be composed of a set of unique data values, and the conversion device 100 constructs a barcode image by expressing a unique data value in a plurality of colors or graphics corresponding to the respective data values.

On the other hand, in the case of a barcode image to be converted from an audio signal, it can be divided into an original barcode image and a connection barcode image.

Here, the original barcode image refers to the barcode image itself converted from the audio signal, and the original barcode image can be stored in a separate storage space such as a server after being converted from the audio signal.

On the other hand, the connection barcode image refers to an image representing a storage address where the original barcode image is stored, rather than the barcode image itself converted from the audio signal. The connection barcode image can be made to have a relatively simple structure than the original barcode image have.

The recognition apparatus 200 performs a function of recognizing the barcode image.

More specifically, the recognition apparatus 200 recognizes the barcode image and reproduces the audio signal, thereby enabling the user to listen to the inputted user voice in relation to the input item of the electronic document.

At this time, when the data corresponding to the text information is encoded in the non-audible frequency band of the audio signal, the recognition apparatus 200 decodes and displays the data corresponding to the text information, To be confirmed.

For reference, in the case of the barcode image recognized by the recognition apparatus 200, the barcode image may be inserted in the electronic document or may be inserted into the electronic document and output in the form of a paper document, The barcode image may have only one independent shape.

Hereinafter, the configuration of the conversion apparatus 100 according to an embodiment of the present invention will be described in more detail with reference to FIG.

That is, the conversion apparatus 100 includes a generation unit 110 for generating an audio signal, a conversion unit 120 for converting an audio signal into a barcode image, a storage unit 130 for storing an original barcode image, And an output unit 140 for outputting an output signal.

Here, all or a part of the configuration of the converting apparatus 100 including the generating unit 110, the converting unit 120, the storing unit 130, and the output unit 140 may be implemented as hardware or software modules Or a combination thereof.

First, the generating unit 110 performs a function of generating an audio signal.

More specifically, the generating unit 110 generates an audio signal including an input user voice when a user voice is input in association with an input item of the electronic document.

For example, when creating a contract or agreement made with an electronic document at a clinic, an insurance / financial institution, a media company, a magazine, or the like, Signal can be generated.

As another example, in publishing, music companies, and the like, a voice of a famous author, an entertainer, or a voice actor is input as a user voice for the purpose of promoting the publication or the work of the self. In addition, Etc.), it is possible to receive a user's voice for the purpose of describing words or phrases, pronunciation, and commentary on a problem.

At this time, the generator 110 arranges the inputted user's voice in the audio frequency band (20 to 20,000 Hz), so that the user's voice inputted in relation to the input item of the electronic document can be audited upon reproduction of the audio signal thereafter.

The input items of the electronic document may further include various text information including, for example, a fingerprint written for the purpose of deriving the user's voice, a signature of the user, and a sentence in which the inputted user's voice is textized.

In generating the audio signal, the generating unit 110 may include not only the input user voice but also the text information in the audio signal together.

In the meantime, the audio signal includes the non-audio frequency band, which is the remaining frequency band except for the audio frequency band in which the user's voice is arranged. The generation unit 110 encodes the text information in the non-audio frequency band.

At this time, the generation unit 110 generates the audio signal in which the text information is encoded in the non-audio frequency band by modulating the text information with the frequency signal of the non-audio frequency band as a data value and encoding the modulated frequency signal do.

When the text information is encoded into the audio signal together with the user's voice, the recognition apparatus 200 decodes the text information encoded in the non-audible frequency band of the audio signal at the time of reproducing the audio signal, Can be displayed.

The conversion unit 120 converts the audio signal into a barcode image.

More specifically, when the generation of the audio signal is completed, the converting unit 120 converts the generated audio signal into a barcode image, and the recognizing device 200 recognizes the converted barcode image to reproduce the audio signal.

Here, the audio signal may be composed of a set of unique data values, and the conversion device 100 constructs a barcode image by expressing a unique data value in a plurality of colors or graphics corresponding to the respective data values.

For example, when displaying a barcode image in a plurality of colors, it is possible to express each data value constituting an audio signal by arranging color elements such as density, saturation, and brightness, for example.

As another example, when a bar code image is represented by a graphic form, each data value constituting an audio signal can be expressed through, for example, a combination of shapes and sizes of various graphic forms.

At this time, the conversion unit 120 divides the barcode image converted from the audio signal into the original barcode image and the connection barcode image, which can be performed according to the security policy of the electronic document issuer.

For example, in the security policy of the electronic document issuer, if it is permitted to insert the barcode image itself converted from the audio signal into the electronic document, there is no need to distinguish the original barcode image from the connection barcode image.

However, if it is not allowed to insert the barcode image itself converted from the audio signal into the electronic document in accordance with the policy of the electronic document issuer, the barcode image converted from the audio signal must be divided into the original barcode image and the connection barcode image.

In this case, by inserting only the connection barcode image into the electronic document, it is possible to limit the barcode image that can be recognized preferentially in the recognition device 200 to the connection barcode image.

In this way, when the connection barcode image is inserted into the electronic document, the recognition device 200 can acquire the original barcode image stored through recognition of the connection barcode image. In this process, .

For this, the storage unit 130 stores the original barcode image, and stores the original barcode image only when the preset authentication information is confirmed from the recognition device 200 So that the recognition device 200 can normally acquire the original barcode image.

Here, the authentication information may be, for example, identification information (e.g., MAC) of the recognition device 200 or a separately set password.

The output unit 140 performs a function of outputting a barcode image.

More specifically, after converting the audio signal into a barcode image, the output unit 140 outputs the output of the electronic document in consideration of the output resolution of the printer in which the electronic document is output when the output of the electronic document in which the barcode image is inserted is requested, .

At this time, the output unit 140 confirms the output resolution of the printer from which the electronic document is output, and if the determined output resolution is equal to or higher than the predetermined output resolution, the output unit 140 inserts the original barcode image into the electronic document and outputs the same.

Here, if the determined output resolution is equal to or higher than the pre-designated output resolution, it may mean that the original bar code image can be output normally.

If the determined output resolution is determined to be equal to or higher than the designated output resolution, the output unit 140 may insert the original barcode image into the electronic document and output the inserted original barcode image together with the electronic document in the form of a paper document .

On the other hand, when it is determined that the output resolution of the printer to which the electronic document is output is less than the predetermined output resolution, the output unit 140 inserts the connection barcode image into the electronic document and outputs the inserted barcode image.

Here, if the determined output resolution is less than the predetermined output resolution, it may mean that the original bar code image can not be output in its original form.

If the determined output resolution is less than the designated output resolution, the output unit 140 may insert a connection barcode image, which is a relatively simple form in the electronic document, rather than the original barcode image.

In this manner, when the identified output resolution is less than the predetermined output resolution, outputting the connection barcode image allows the recognition device 200 to recognize the original barcode image that is abnormally output due to the low output resolution of the printer, Is prevented from being reproduced, or when the audio signal reproduction itself is impossible.

The providing unit 150 performs a function of providing the original barcode image.

More specifically, when the bar code image converted from the audio signal is divided into the original bar code image and the connection bar code image, the providing unit 150 acquires the original bar code image stored from the recognition apparatus 200 that recognizes the connected bar code image .

In this case, the providing unit 150 confirms the authentication information applied to store the original barcode image from the recognition apparatus 200, and determines whether the authentication information confirmed from the recognition apparatus 200 matches the authentication information applied to store the original barcode image And provides the stored original bar code image to the recognition apparatus 200. [

Meanwhile, the above-described operation related to providing the original barcode image in the providing unit 150 may be performed in conjunction with a storage medium (server) storing the original barcode image. In this case, Lt; / RTI >
