Abstract: In order to develop new technologies capable to exploit the digital identity concept, increasing the security and safety of involved systems by elaborating models based on data from the systems is strongly required. The mentioned input data are gathered from users’ authentication process. Currently, the authentication process for recognizing the digital identity of one person or organization is raising serious challenges. There are two key terms when someone is referring to digital identity of an entity: identification itself, which defines the process of identifying the person, and authentication, which represents the process of confirming the identity. The main purpose of this study is to present a two factors authentication approach which aims to increase the efficiency of a classical authentication based on username and password. For this type of authentication, different keys can be combined in order to offer a safer access to various resources. This paper presents both advantages and disadvantages of the described approach as well as a practical implementation based on token installed on a smartphone. In order to highlight the afore mentioned theoretical aspects related to digital identity and authentication, a mobile application was designed and implemented. The application is presented in Chapter 3.

Keywords: authentication, security, digital identity, two factor authentication, token, multi- factor authentication.
