A multi-channel lossless image transfer method hidden

The present invention discloses a multiplexed transmission image lossless hiding method for hiding the main image transmission. Currently typical lossless information hiding method requires the extraction of a large amount of additional information, regardless of the hidden capacity in case additional information is only about 1/8, and there is no robust: any change with dense cover image will cause secret information It can not be extracted properly. The present invention proposes a new method, to break the routine, information hiding by using redundant information to construct a new vector for the embedded secret information. This method can be restored at the receiving end and the support lossless hidden information, the relative capacity of up to 1/2, and this concealment method has a larger capacity compared to the hide. The present invention can be non-destructive restore the secret information carrier and in a case where there is some error in the channel (e.g., 20% error rate), a certain robustness.
