The orthogonal transform such as CT transform is performed, and the resultant is sent to the multiplex processing unit 14 as an 8 × 8 frequency component matrix. The telephone number to be embedded is assigned an identification code by the code allocating unit 17, and is similarly sent to the multiplex processing unit 14.

Prior to the embedding of the identification code, the embedding position indicating information embedding position in the frequency component matrix obtained by the orthogonal transformation process is determined by a random number, and how much the value of the frequency component is changed Is determined, and the embedding position and the change amount are obtained and stored as key information. By selecting, for example, a low frequency portion of the frequency component matrix as the embedding position, the embedding can be performed so that it cannot be perceived by humans. Also, by changing the change amount, the difference from the original value of the frequency component matrix can be changed, so that the deterioration of the image quality can be controlled.

The multiplexing processing unit 14 changes the value of the frequency component matrix of each block and performs identification when quantizing with an appropriate quantization coefficient or performing variable length coding based on the key information. The code is multiplexed and embedded in the image data. Then, the inverse orthogonal transform is performed by the inverse orthogonal transform unit 15 to obtain 8 ×
The block image of 8 pixels is obtained, and the reconstruction processing unit 16
By connecting the respective block images, an embedded image in which the telephone number is embedded is output.

In the figure, reference numeral 21 denotes a block division unit, 22 denotes an orthogonal transformation unit, 23 denotes an extraction processing unit, and 24 denotes a telephone number conversion unit. .

In the above configuration, the embedded image is divided into 8 × 8 pixel blocks by the block dividing section 21, and orthogonal transform such as DCT is performed for each block by the orthogonal transform section 22, and an 8 × 8 frequency component matrix And sent to the extraction processing unit 23. The extraction processing unit 23 obtains an embedding position and a change amount from the key information used at the time of embedding, and extracts an identification code from the frequency component matrix of each block. The extracted identification code is returned to the telephone number by the telephone number conversion unit 24 and output.

At this time, by storing the above-mentioned key information in the apparatus so that it cannot be read, a telephone directory apparatus from which a telephone number cannot be retrieved without this key information can be configured.

Further, by using this telephone directory device, it is possible to call and call the other party by a simple operation. In addition, necessary face photo information of the other party is selected from the electronic telephone directory and stored in another storage unit. In the case where the name is forgotten, the face photograph information stored in the separate storage unit can be sequentially read out and scroll-displayed to select the other party and make a telephone call.

Although the above description is directed to the case where the present invention is applied to a general telephone directory, the present invention can also be applied to a device having both a telephone directory and a photo book in a company or the like. In this case, personal information is embedded in the face photo information together with the telephone number, and the embedded information is extracted and restored and displayed on the screen, so that the user can make a call while viewing the personal information, and the telephone directory is externally accessible. No personal information is leaked when taken out.
