Open challenges in smart cities: Privacy and security

Construction of smart cities is no longer a future endeavor. Even though the implementation of smart city comes with enormous conveniences, the realistic implementation is challenged in different aspects. Two of the major aspects along with the design, maintenance and implementation costs are privacy and security. The frameworks introduced for smart city impose many challenges regarding privacy and security of the citizens. Open networks, smart phones, computers etc. are used for the communication in the smart city, making the sensitive data vulnerable to attacks. It is also vital to deal with the privacy issues. Thus, maintaining security and ensuring the privacy in the smart city is necessary and turning out as an open challenge. The present paper proposes Cloud Data Security Model (CDSM) for the better security of data using the cloud storage mechanism. The CSDM proposes four different categories of cloud accounts with special permissions to access the data. Moreover, with the data access record, the owner is completely aware of who is accessing the data.
