In this paper is documents the development of the work of a security system for mobile devices based on Facial recognition. This recognition is based on the algorithm of Wu and SUSAN, it was obtained for 80% efficiency and was implemented in iOS platform. The cell phone is used for a host of activities is therefore necessary maintain secure information. One of the ways is through the recognition and fingerprint biometric facial features, etc. We propose not only the recognition of patterns biometrics; also added recognition of basic emotional states. Thereby providing a new form security for access to cell is achieved.
