Encoding decryption data into a pattern of merge bits

Abstract

Decryption or descrambling information or other data modification information is encoded into patterns of merge bits for primary information. The decoded information is used to decrypt, descramble or otherwise modify the primary information. In another embodiment, a sequence of symbols is added to original data, the sequence of symbols selected to encode into channel bits having a large accumulated digital sum variance. In another embodiment, a single symbol in the sequence of symbols is replaced after error correction symbols have been added. In another embodiment, decryption or descrambling information or other data modification information is encoded into the sign of the digital sum variance of each blocked row of data.

What is claimed is:  
     
         1 . A method of transmitting decryption data, the method comprising the following steps: 
 (a) encoding a bit of decryption data into a pattern of merge bits;    (b) encoding channel bits having the pattern of merge bits of step (a); and    (c) transmitting the channel bits resulting from step (b).    
     
     
         2 . The method of    claim 1   , further comprising using the decryption data for inhibiting copying of digital information, the method comprising the following additional steps: 
 (d) decoding the channel bits from step (c);    (e) decoding the pattern of merge bits in the channel bits of step (d) back into the bit of step (a); and    (f) using the decoded bit of step (e) to modify the decoded channel bits of step (d).
