Wireless Data Authentication Using Secure Force Algorithm

In wireless communications, authentication and secure transmission is the need of the hour especially in bank and military communication .The encryption and hiding of image data has been common these days .To improve the security of image transmission to an advanced level, we proposed the concept of secure -force algorithm at the encryption level .Consider the user wanting to send a biometric image being hidden in a image. The image thus obtained is subjected to secure force algorithm, after the encryption to provide invisibility and resistance against lossy transmission. The signal is inserted into QSWT followed by IDWT. Experimental results:(a) increase security (b) bandwidth efficiency (c) hacking would be difficult for the attackers.
