DATA CONCEALMENT APPARATUS AND METHOD USING AN ERROR CORRECTION CODE

Disclosed are a data concealment apparatus and a data concealment method using an Error Correction Code. According to exemplary embodiments of the present invention, it is possible to prevent important information from being easily exposed to a third person by generating encoding data through convolution encoding of input data and thereafter, concealing the encoding data on an image through adjustment of a pixel value on the image and minimize an error which can occur at the time of recovering the input data by extracting the encoding data from the image in a soft decision scheme and performing Viterbi-decoding on the extracted encoding data in order to recover the input data concealed in the image.
