A method and apparatus for watermarking digital data is described herein whereby the digital data is decomposed into a plurality of original data segments, one or more of the original data segments replicated at least once to generate replica data segments, a set of watermarks is generated, each watermark is applied to a respective data segment to generate watermarked data segments, the data segments are encrypted using encryption keys to generate encrypted data segments. One or more embodiments of the invention include providing a subset of the encryption keys corresponding to a subset of the encrypted data segments, wherein each encrypted data segment in the subset of the encrypted data segments, can be decrypted using a corresponding encryption key in the subset of encryption keys, and wherein the decrypted data segments can be combined to reconstruct the digital data including one or more of the watermarks. |
