## 4 Discussion  
The main objective of this descriptive survey was to explore the University of the Aegean students' BS acceptance, focusing on their social and demographic information and their privacy concerns that play an important role toward this in order to provide deeper insight regarding BS acceptance in Greece and in particular for Greek University students. Since similar surveys are lacking in the Greek social reality, there is a need to identify the current trends at first. Regarding this, findings are discussed and compared with previous research in other countries not on a score basis, since samples and cultural issues are varied, but as useful information before further research can be carried out. As Ref. [47] argued, users' behavior and attitudes toward technologies are led by their mentality, so it is immensely important for designers and developers to recognize and comprehend users' perceptions when developing and realizing such systems. Summarizing our findings, it has emerged that most of the University of the Aegean (UA) students are familiar with the concept of BSs, and they believe that they can simplify their everyday lives. Thus, BSs are not adopted in their everyday practices to a great extent, while techniques, such as hand geometry, are not used at all. This is not the case for the fingerprint technique, which is the most popular technique, especially for mobile phones' unlocking. This supports the previous research findings, such as Ref. [48], by which it is indicated that adults acknowledge and feel more comfortable to use the fingerprint technique, while the mobile phone industry promotes this technique more often [49]. Most of the participants consider BSs to be easy to learn and use, referring thus to the most-known ones, fingerprinting and face recognition. Their unfamiliarity with plenty of techniques, such as keystroke or hand geometry, presupposes that BS-aware training is needed, despite the fact that the majority of students believe that training is not required. Ref. [6] emphatically supports that plenty of people are still lacking information regarding the BS role and their functioning, resulting in not understanding how BSs can make their life simpler and the effective ways of identification compared to traditional methods. This has a negative impact on users' acceptability. In this regard, BS distribution

Considering that UA students support that the greater BS advantage concerns accurate identification based on their unique characteristics, and the greater disadvantages concern the fear of unauthorized accessing and processing of their personal information, as well as violating their privacy by third parties, which are common ones among users worldwide [48], BS training is of great importance in order for BS acceptance to be increased within Greek HEIs. Public trust and acceptance are key parameters for the adequate deployment of BS systems, since when they are lacking, it likely leads to implementation difficulties, inconvenience, and false acceptance rates that increase distrust among users and discourage public and private services from using them in their daily function [50]. Toward this, it is also important that UA students are not fully convinced regarding BS reliability for identification, even though a large proportion of them, being tired of the plethora of passwords, supports that BSs are more reliable and safer than passwords/PINs. UA students also believe that BS utilization may reduce personal information thefts, similar to previous research [51], where American users supported that face recognition in working environments is a capable solution for this reduction.
