<p>To code a digital object (310), a sender (110) preferably encrypts (210) its data to obtain a bitstream that is converted (230) into a set of points (320) that are then packaged (240) and the coded object (330) is output (250). A receiver (140) receives (260) and unpacks (270) the coded object (330) to obtain the set of points (320), converts (280) the set of points (320) to a bitstream that, if needed, is decrypted (290) to generate the original object (310) that is output (295). The invention is particularly suited for protection of 3D objects, but it can also be used to protect any kind of digital data, in which case it may be possible to append the protected data of another kind to a 3D object.</p> |
