Architectures to Implement In-Air Signature Mobile Authentication to Increase the Security of E-Commerce Applications and Opinion of End Users

This article proposes to include an in-air signature biometric technique in mobile e-commerce applications in order to increase the security of passwords and authenticate users directly from their mobile phones. Five architectures have been proposed to implement this technique as a complement of current authentication methods. Moreover, the opinion of end users has been considered assessed by a survey of 24 people. From the results of this survey it has been deducted that this authentication method seems useful, necessary and comfortable to complement the password authentication methods and increase the global security of e-commerce applications.
