With a growing rate of mobile usage in the current networking era, mobile devices have been adopted widely. With mobile proliferation, location awareness is gaining huge insights in mobile and communication technologies for which, information subsystem has to be maintained on geo-located systems. Location Dependent Services (LDS) fetch relevant information from the geo-located information subsystems and deliver it to the user based on their location preferences and choices. Despite having the desirable features and services, LDS does not provide satisfactory protection to the user’s geographic location. Preservation of location has become one of the utmost concerns in mobile network communication. In this paper, we will go through the security & privacy challenges for LDS in mobile networks. Precisely, this paper covers the cryptographic approaches and technologies to enhance privacy to promote location privacy in mobile network communication. The different approaches covered in the review are first compared and then the further research areas have been identified as well as concluded.
COVID-19 has had a major impact on the world economy, company operations, and individuals. However, technology is additionally helping several businesses in adapting to and overcoming this crisis obligatory by COVID-19. The augmented usage of technology in people' and businesses' daily lives in response to the present extraordinary situation is proof of the digital acceleration process. This preliminary analysis investigates the consequences of digital transformation processes in 3 corporate areas: labor and social relations, promoting and sales, and technology. The influence of digitalization is probably going to be cross-cutting across all areas, encouraging the introduction of recent digital merchandise and services based on the flexibleness concept. Furthermore, new modes of operating will increase the demand for brand new talent no matter wherever people live. Furthermore, cybersecurity and privacy will become 2 crucial elements that may assist the integrated development of net of Things technological solutions, artificial intelligence, and machine learning.
: In the world of the latest technologies, the blockchain is one of the popular techniques for stopping fraudulent activities. Non-Government Organization (NGO) is increasingly being used to support all the needy people across the globe to shape the world’s responsibility towards society for sustainable development. The existing method of donating money and its monitoring is faced with a major corruption problem in several world-renowned NGOs. A blockchain can transform the way the current business of money transaction is being done in NGOs. The blockchain-based application works on the concept of a decentralized system. This article presents a blockchain-based transaction system to prevent corruption and money laundering in NGOs and government fundraising organizations. A Smart contract has been designed to stop any illegitimate block changes during a financial transaction. Since every node has a copy of the ledger, so it is very difficult to perform malicious activity. Furthermore, the donator can watch how the money flows in the different transactions, and everyone can browse the account history. An evaluative judgment, compared with various consensus algorithms, has also been presented along with their complex nature. The decentralized approach has eliminated the chance of a single point of failure, which in turn makes the system robust. The developed framework for the financial transaction using blockchain has been tested using the Rinkeby Test Network. The generators and campaign contracts have been developed and deployed in the Rinkeby testing network. The results indicate the computing to be much more secure and free from the scam in comparison to the traditional client-server financial transaction system. Finally, the proposed approach suggests scenarios such as in NGOs where the introduced security approach should prove to be adequate.
