Claim:
1. A data embedding apparatus comprising: a data acquisition unit configured to acquire first data formed from a first bit string to be embedded in a first object including one of a first line segment and a first curve; a weight vector generation unit configured to convert the first bit string into a weight vector; a displacement calculation unit configured to calculate a waveform of a displacement by weighting a plurality of encoding bases formed from a plurality of predetermined waveforms by elements of the weight vector; an object generation unit configured to generate a second object, which includes one of a deformed line segment and a deformed curve having a displacement corresponding to the first bit string with respect to one of the first line segment and the first curve and in which the first data is embedded, by deforming, by the displacement represented by the waveform of the displacement, at least one of the first line segment and the first curve of the first object based on the first bit string; and an object output unit configured to output the second object.
