Patent abstract
The present invention relates to message encoding. In a first implementation, a message is provided. The message is transformed by a secret key. The secret key is generated by providing a plural-bit seed. The seed is randomized and then error correction encoded. We prefer tail-biting convolutional encoding for our error correction encoding. The encoded seed forms a secure key, which is used to transform the message prior to embedding.
