摘要：The mobile network security is becoming more important as the number of data being exchanged on the internet increases. The growing possibilities of modern mobile computing environment are potentially more vulnerable to attacks. As a result, confidentiality and data integrity becomes one of the most important problems facing Mobile IP (MIP). To address these issues, the present paper proposes a new Wavelet based watermarking scheme that hides the mobile signals and messages in the transmission. The proposed method uses the successive even and odd values of a neighborhood to insert the authenticated signals or digital watermark (DW). That is the digital watermark 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 using LSB method. This makes the present method as more simple but difficult to break, which is an essential parameter for any mobile signals and messages. To test the efficacy of the proposed DW method, various statistical measures are evaluated, which indicates high robustness, imperceptibility, un-ambiguity, confidentiality and integrity of the present method.
