abstract = "In order to block the access of the information in the smartphone of a user by other users, it is checked if the current user is the owner or not in the smartphone authentication process, whenever a user begins to use a smartphone. This makes smartphone users in front of frequent smartphone authentications, which leads significant inconvenience to them. Because of such inconvenience, users tend not to use the smartphone authentication anymore. Finally, their smartphones become very vulnerable against malicious access. This paper proposes a progressive authentication method on the android-platform in order to solve the problem described above. With the proposed method, smartphones can identify relevant risks based on users" past experiences and determine whether an authentication is needed. Because authentication occurs only when the identified risk level is high, it can achieve both a high-level of security in the high-level risk situation and user convenience in the low-level risk situation."
