In this paper biometric methods for user-centric, contactless and unrestricted access control dedicated for mobile devices are proposed. The major contribution is a novel low computational cost palmprint texture feature extraction method. Contactless biometrics fits into the user-centric paradigm since users do not like to touch acquisition devices. Furthermore, the usage of mobile devices (cellphones, handhelds) for biometrics is interesting both for users and system/service providers (due to low cost, wide acceptance and penetration, mobility and user-friendliness). Our methods can be used in mobile biometrics scenario since mobile end-terminals portfolio has exploded with devices providing greater functionality and usability with more processing power.
