Referring to FIG. 6, the sound picture server receives source data including picture data and sound data from a first terminal provided as a personal computer or a mobile communication terminal (S102).
In addition, the sound photograph server generates sound photographs by hiding sound data in the received photograph data according to a predefined watermarking insertion rule (S104).
In this case, the watermarking insertion rule generates a hidden coefficient and a hidden order from the photo data. That is, the watermarking insertion rule sets higher concealment coefficients for light pixels of the picture data than dark pixels, allocates more bits when concealing sound data, and sequentially conceals in the order of high frequency band to low frequency band. have.
On the other hand, when the sound picture server receives a sound picture request from the first terminal provided as a personal computer or a mobile communication terminal (S106), the first terminal is determined to receive sound picture by determining authentication information including an ID and a password. If so, the generated sound picture is provided to the sound picture request terminal which is the first terminal (S108).
7 is a flowchart illustrating a sound insertion method according to the present invention.
Referring to FIG. 7, for example, the sound picture server reads a JPEG header from JPEG picture data (S202) and performs Huffman decoding to decode a Huffman code (S204). Huffman Code is a variable length code that can shorten the average code length in digital transmissions.It is an image or video compression standard JPEG due to its simple implementation and high compression efficiency. It is used for various data compression such as MPEG-1, MPEG-2, MPEG-4. Given a probability distribution for the frequency of occurrences for a set of symbols, the Huffman code expresses symbols with high frequency as short codewords and symbols with low frequency as long codewords. It aims to reduce the amount of average transmission data.
The sound photograph server extracts DCT coefficients by performing the Huffman decoding (S206).
On the other hand, the sound picture server hides the sound data in the photo data using a predefined watermarking insertion rule (S208).
In this case, the watermarking insertion rule generates a hidden coefficient and a hidden order from the photo data. That is, the watermarking insertion rule sets higher concealment coefficients for the brighter pixels of the picture data than the darker pixels to allocate more bits when concealing the sound data, and sequentially conceals the high-frequency bands in the order of the low-frequency bands. . For example, according to the watermarking insertion rule, a concealment coefficient of 4, 3, and 2 is assigned to each of three brightnesses of R (red), G (green), and B (blue) according to respective brightnesses. It is possible to generate the number of bits capable of concealing the sound data from the picture data. In addition, since the hidden coefficients are sequentially hidden from the high component, when the same hidden coefficients can be sequentially hidden in the order of high frequency band to low frequency band. Here, the concealment method is to initialize the existing data of the bit allocated as the concealment bit and insert sound data into the initialized bit.
Thereafter, the sound photograph server performs Huffman encoding on the photograph data where the sound data is concealed (S210).
8 is a flowchart illustrating a sound extraction method according to the present invention.
Referring to FIG. 8, for example, the sound photograph server reads a JPEG header from JPEG sound image data (S302), and performs Huffman decoding to decode a Huffman code (S304).
The sound photograph server extracts the quantized Discrete Cosine Transform (DCT) coefficients by performing the Huffman decoding (S306).
On the other hand, the sound picture server checks whether the watermark header is extracted from the sound picture data (S308).
As a result of the checking, when the watermark header is extracted, the sound picture server extracts sound data from the sound picture data according to the watermarking extraction rule using a predefined watermarking insertion rule (S310).

Referring to FIG. 10, the sound picture terminal receives a picture image from the user (S402). In addition, the sound picture terminal receives a sound or a string from the user (S404).
In addition, the sound photograph terminal generates a sound photograph by concealing the sound or character string in the photograph image according to a predefined watermarking insertion rule (S406).
On the other hand, the sound picture terminal checks whether the terminal storage is selected by the user (S408), and if the terminal storage is selected and stores the sound picture in the sound picture terminal (S410).
On the other hand, when the terminal storage is not selected, the sound picture terminal checks whether server storage is selected (S412), and when the server storage is selected, uploads the generated sound picture to the sound picture server (S414).
The present invention is not limited to the above embodiments, and various modifications may be made by those skilled in the art within the technical spirit of the present invention.
For example, the sound picture generation of the present invention has been described as being processed by the sound picture providing server. However, the sound function is implemented by inserting sound data into the picture data according to the watermarking insertion rule in the terminal by implementing the function of the server in the terminal.
