Abstract:
Mobile communication devices have become popular tools for communicating among people. This paper is a launcher for sending/receiving secured SMS/Multimedia files using Blowfish algorithm. A smart mobile application on android platform is introduced as an application that helps the user to encrypt the message (SMS/Multimedia files) before it is transmitted over the mobile network. The new idea of the program is to transmit encrypted messages and multimedia files or any other type of files via mobile networks or the internet as an alternative mean. Utilizing the internet takes place through a secured hosting website with a user name and password integrated in the program. To maintain intensive security, a private key encrypts the files and another private key encrypts file name. The transferring media is maintained online in the absence of mobile network coverage.
