%X The mobile network security is becoming more important as the number of data being exchangedon the internet increases. The growing possibilities of modern mobile computing environment arepotentially more vulnerable to attacks. As a result, confidentiality and data integrity becomes oneof the most important problems facing Mobile IP (MIP). To address these issues, the presentpaper proposes a new Wavelet based watermarking scheme that hides the mobile signals andmessages in the transmission. The proposed method uses the successive even and odd valuesof a neighborhood to insert the authenticated signals or digital watermark (DW). That is the digitalwatermark information is not inserted in the adjacent column and row position of a neighborhood.The proposed method resolves the ambiguity between successive even odd gray values usingLSB method. This makes the present method as more simple but difficult to break, which is anessential parameter for any mobile signals and messages. To test the efficacy of the proposedDW method, various statistical measures are evaluated, which indicates high robustness,imperceptibility, un-ambiguity, confidentiality and integrity of the present method.
