Résumé:
In recent years, there is an increasing use of various types of applications in many fields such as government, smart cities, health, social networks...etc. In this situation, the amount of user data has been increased and hence new protocols and strategies need to be put in place to manage and process this big data. One of the biggest issues that data can face is the privacy and security of its use by apps and other parties. Thus, maintaining the confidentiality and security of data and using it reliably is the main goal of many research directions. Blockchain technology, which is a secure and decentralized database, can be used to solve this problem to keep user data private.
In this thesis we present an approach based on the use of blockchain to maintain confidentiality and data with respect to the Algerian Regulation of Data Protection based on Bloackchain
