The purpose and object of this bachelor’s dissertation, is the personalized sharing of files with security, as it is deemed necessary for the protection of sensitive personal data, while at the same time it contributes to flexible access and collaboration in different environments. The goal, however, becomes the development and evaluation of a specific proposal that allows secure file management and sharing with personalized settings for each user.
In a first stage, basic concepts related to encryption and security, private/public key, digital signature and 3-tier architecture are presented, in order to clarify the understanding of their application and its functions. A cornerstone of the application is the definition of data security. In this context, various practices and technologies have been established that are deemed necessary to be taken into account to achieve the security of files during transport and storage.
In a next stage, the development of a web application that encrypts and shares files between users on a local network is presented. The clear definition of data security and how it is carried out is the main purpose of the application.
