The aim of research is proposal of the system architecture which enables the information delivery in traffic environment to a subset of users (persons with visual impairment, hearing impairment, locomotor impairment, the elderly, children and people with no disability). The purpose of service is to provide users with accurate and real-time information and raising the level of quality of life. The proposed information and communication system architecture is based on modern technologies, while the system architecture is based on Cloud Computing for the Blind concept ensuring 24/7 support for the delivery of services and safety of users. Solution is realized in the form of smart bracelet that uses sensors to collect data from the environment and forwards them for further processing. With simulation testing and experimental methods, the work of proposed system is tested in laboratory and real-world environment which proved real-time information delivery to users. Having the ability to notify users in real time will increase the level of autonomy and safety while moving through traffic network.

Within this paper, a conducted survey analyses the knowledge on the term of the use of personal device in the corporate environment and employee awareness of security issues that arise with introducing BYOD trend in business. BYOD represents a risk to business, usually present as the risk of data theft, unauthorized access to applications and systems of corporation, loss of reputation and such. BYOD, like any other system, must be systematically planned, implemented, monitored and improved. Employees are not sufficiently educated and aware of the security risks that BYOD brings.
