USE OF BLOCKCHAIN ​​TO GUARANTEE AUTHENTICITY

 In addition to the diplomas and certificates covered in the previous section, there are several other academic documents that need to be issued and stored securely. Such documents serve, for example, as proof of the training received by the student and his academic trajectory. Examples of these documents include evidence, history, among others. Security is important in this context because, for example, information such as grades in courses taken can be subject to adulteration to increase the chances of hiring a particular job.


Srivastava et al . (2018) suggest the creation of a blockchain-based data recording platform that registers, through tokens , all credits acquired by the student throughout his academic trajectory. Each university in the system has a blockchain node and is responsible for generating identification credentials for its students by verifying the authenticity of their personal documents.


Each student has his digital wallet, where tokens are registered for each course completed at the institution. This allows the student to reliably prove the training received, and will reduce the existing bureaucratic procedures if he needs to change the educational institution, as the data can be consulted on the Blockchain itself. The work describes the implementation of the Blockchain used in the project and presents the main algorithms developed. These algorithms are intended to register the student, register the educational institution, achieve network consensus, among other functions.


Currently, most academic documents are printed on paper and stored in physical files. The existing digital databases are mostly centralized and with restricted access. When transferring to a new school, the student needs to redo his entire registration, with no facility to reuse the data from the previous institution. Therefore, Bore et al. (2017), in their work, address the lack of complete, accessible and updated educational databases. This hampers data analysis and decision making by institution managers and the government.

Desktop Support Technician is known as one of the backbones of IT organization. They are also accountable for groundwork, installation, and maintenance of end user workstation equipment (laptops/ desktops) and additional peripherals including IP telephones.

The work proposed by Bore et al (2017) presents the design, implementation and evaluation of a School Information Hub integrated with a Blockchain in order to decentralize the data and keep it safe and accessible. In the proposal, all school activities and occurrences would be recorded in the form of transactions on the Blockchain. Examples of transactions include: registering new students, enrolling or re-enrolling in subjects, updating the user's identity, registering student attendance, etc.
