Given this wide nature, these solutions are considered very suitable for application in Smart Cities environment. The main objective of Smart Cities is improving the daily life of the citizens. This can be done by providing ad hoc and user centered services, from customized advertising to urban traffic live information and pedestrian security. In order to provide such services, it is important to gather and analyse the most of data available in the environment, by designing ad-hoc cloud solutions, such to offer information about the three factors that may serve as basis for specific services: user, context and actions. User informations can be obtained by recognizing a subject by means of his/her discriminative biometric data, and also by studying the citizens’ habits. Actions informations can be obtained by analyzing the movement of the subject and his/her relationships with the surrounding environment and/or other users. Finally, the context gives insights about the meaning of the actions which may be verticalized within an environment or a relationship. This issue aims at gathering works which proposes biometric systems and solution for Smart Cities of enhancements in technologies for gathering, analyzing and protecting user and environmental data.</p><div class=""><br class=""></div><div class="">Keywords</div><div class="">============================================</div><div class=""><ul class="" style="box-sizing: border-box; margin: 10px 0px 1.25rem 1.1rem; padding: 0px; font-family: Arial; line-height: inherit; list-style-position: outside; max-height: 1000000px; caret-color: rgb(34, 34, 34); color: rgb(34, 34, 34); text-align: start;"><li class="" style="box-sizing: border-box; margin: 0px 0px 10px; padding: 0px; max-height: 1000000px; break-inside: avoid;">Cloud-based Architecture for Biometric Systems in Smart Cities</li><li class="" style="box-sizing: border-box; margin: 0px 0px 10px; padding: 0px; max-height: 1000000px; break-inside: avoid;">Cloud-based Communication Protocols for Biometrics</li><li class="" style="box-sizing: border-box; margin: 0px 0px 10px; padding: 0px; max-height: 1000000px; break-inside: avoid;">Biometric Security and Privacy Policy</li><li class="" style="box-sizing: border-box; margin: 0px 0px 10px; padding: 0px; max-height: 1000000px; break-inside: avoid;">Biometric Access Control of Cloud Data</li><li class="" style="box-sizing: border-box; margin: 0px 0px 10px; padding: 0px; max-height: 1000000px; break-inside: avoid;">Biometrics-as-a-Service solutions</li><li class="" style="box-sizing: border-box; margin: 0px 0px 10px; padding: 0px; max-height: 1000000px; break-inside: avoid;">Biometric Fusion in the Cloud</li><li class="" style="box-sizing: border-box; margin: 0px 0px 10px; padding: 0px; max-height: 1000000px; break-inside: avoid;">Biometric Cryptograpy and Encryption in Cloud Computing</li><li class="" style="box-sizing: border-box; margin: 0px 0px 10px; padding: 0px; max-height: 1000000px; break-inside: avoid;">Biometric recognition in Smart Cities</li><li class="" style="box-sizing: border-box; margin: 0px 0px 10px; padding: 0px; max-height: 1000000px; break-inside: avoid;">Cloud Based approaches for Biometrics</li><li class="" style="box-sizing: border-box; margin: 0px 0px 10px; padding: 0px; max-height: 1000000px; break-inside: avoid;">Gait Analysis and Recognition</li><li class="" style="box-sizing: border-box; margin: 0px 0px 10px; padding: 0px; max-height: 1000000px; break-inside: avoid;">Pattern Recognition in Smart Cities</li><li class="" style="box-sizing: border-box; margin: 0px 0px 10px; padding: 0px; max-height: 1000000px; break-inside: avoid;">Context Awareness Systems for Smart Cities</li><li class="" style="box-sizing: border-box; margin: 0px 0px 10px; padding: 0px; max-height: 1000000px; break-inside: avoid;">Pedestrian and Crowd analysis</li><li class="" style="box-sizing: border-box; margin: 0px 0px 10px; padding: 0px; max-height: 1000000px; break-inside: avoid;">Accident Detection and Road Traffic Analysis</li></ul></div><div class=""><br class=""></div><div class="">Submission Information</div><div class="">============================================</div><div class=""><p class="" style="box-sizing: border-box; margin: 0px 0px 10px; padding: 0px; font-family: Arial; line-height: 1.6; text-rendering: optimizeLegibility; max-height: 1000000px; caret-color: rgb(34, 34, 34); color: rgb(34, 34, 34); text-align: start;">Manuscripts should be submitted online at <a href="https://www.mdpi.com/" class="" style="box-sizing: border-box; color: rgba(7, 116, 182, 0.75); line-height: inherit; text-decoration: none; max-height: 1000000px; font-weight: 700;">www.mdpi.com</a> by <a href="https://www.mdpi.com/user/register/" class="" style="box-sizing: border-box; color: rgba(7, 116, 182, 0.75); line-height: inherit; text-decoration: none; max-height: 1000000px; font-weight: 700;">registering</a> and <a href="https://www.mdpi.com/user/login/" class="" style="box-sizing: border-box; color: rgba(7, 116, 182, 0.75); line-height: inherit; text-decoration: none; max-height: 1000000px; font-weight: 700;">logging in to this website</a>.
