Through the proliferation of multimedia computing devices it has become much simpler to capture and share photographs. However, this large number of devices also makes photo collections more dispersed, making it difficult to maintain them for long periods of time. Cloud systems enable to integrate devices and users in a distributed way, but also restrict users' control over their data and raise privacy concerns. Decentralized systems can contribute to solve these problems by allowing users to maintain control over their data while enabling the integration between devices and cooperation between people. There are, however, several technological challenges for the development of this type of system. In this work, we identify some of these challenges and develop a software library to contribute with the solution of part of them, related to the decentralized connection between peers, and the decentralized location and identification of services. We also present, in this work, a platform we have developed to allow the use and preservation of photography records of memories (photo-memories). We applied the developed library to allow the decentralized communication between the platform’s clients and services.openAccesssistemas distribuídosdistributed systemssistemas descentralizadosdecentralized systemsfotografiaphotographymemóriamemorybachelorThesisCNPQ::CIENCIAS EXATAS E DA TERRA::CIENCIA DA COMPUTACAO
