Multimedia image data processing on smartphone for authentication

The spread of smartphones is rapidly increasing. Such smartphones mainly handle image and video data. In particular, there are many security problems that may occur at this time when there are many accesses to multimedia image data. But most systems use various technologies for user authentication such as identification/password (ID/PW), the certificate, One-Time Password (OTP), fingerprint/iris recognition, etc. When using ID/PW technology, the system is vulnerable, if ID/PW is disclosed to a hacker. The certificate or fingerprint/iris recognition technologies are more secure than ID/PW technology, but they require more cost, and they are complex to build. In this paper, we propose the method for enhancing user authentication. The proposed method improves security at a low cost using the user’s authentication information and the user’s smartphone IMEI information. In particular, IMEI information can be seen to provide a fast right and secure authentication mechanism to perform user authentication of multimedia image processing. In our research method, it is much safer and superior responsiveness than authentication methods using only user ID / Password on smartphones.
