Modern electronic communication is fast and ef icient. It has never been easier to change the document's content. In this paper, we explain and show through practical work how it is possible to protect the data sent electronically in business communication by using decentralized authentication systems.

In this paper, student mobility is observed as one of the steps in realization of the Digital Agenda of the European Union. Student mobility, as one of the main principles of the Bologna process, is the means of effectiveness increase and quality of the educational system in European Higher Education Area, EHEA, because it enables better exchange and flow of knowledge and ideas, as well as the adoption of good practices. Management Identity (IdM) system of the Higher Educational institution is a system which supports student mobility by using personal information when accessing data. The basic identity document in this system is a student smart card with the owner’s fingerprint. This biometrical data insures high level of data and identity protection. This paper proposes informational system which, in itself, contains standards for student mobility support as one of the modules of the IdM system of the Higher Educational institution.

In developed Information Society, creation, distribution and manipulation of information becomes significant economical and cultural activity. The Identity Management is a system used to support managing of personal information of users. The Identity Management System is very convenient for the support mobility of students, teachers and scientific workers in European High Education Area by beforehand established standards for attributes of identity. The basic identity document in this system is a student smart card with the owner's fingerprint. This biometrical data insures high level of data and identity protection.

This paper presents an overview of the new possible concept for the application of smart mobile devices (smartphones, tablets) in defined environments. Practical work that has been done (control of smart solar house) is presented in two planes. The first plane is observe a defined environment, smart solar house with all the necessary functional requirements, hardware elements and communication modules. The second plane is the Android application that is a 3D interface to communicate with mobile devices and smart components of solar home. The work represents an excellent experimental basis in the teaching of programming and robotics. The proposed solutions are based on the work and research using the latest smart mobile devices, communication modules and software.
