While enriching the user experiences, the developmentof mobile devices and applications introduces new securityand privacy vulnerabilities for the remote services accessed bymobile device users. A trusted and usable authentication architecturefor mobile devices is thus in high demand. In this paper,we leverage a unified structure, consisting of transparent TFTbasedfingerprint sensors, touchscreen, and display, to propose anovel identity management mechanism that authenticates usersof touch based mobile devices for accessing the local devicesand remote services. Our solution differs from the previous onetimeand enforced authentication approaches through two novelfeatures: (i) user transparent authentication process, requiringneither password nor extra login steps and (ii) continuousidentity management based on fingerprint biometric, where eachuser-to-device touch interaction is used toward authentication.Moreover, we introduce two different security scenarios, one forlocal identity management, and the second extended solution forremote identity management. Finally we employ TRUST (TrustReinforcement based on Unified Structural Touch-display) tosolve the identity challenge in cyber space.
