Bisera Milosheska (2012) On data integrity in cloud storage. EngD thesis.
The diploma thesis elaborates the problem of integrity and availability of data saved in cloud storage. At first, the reader is introduced with the basics of the studied problem and the reasons why precisely this theme deserves the scope of our attention. The brief introduction is followed by a deeper analysis of the state of the art of the technological evolution, i.e. cloud computing. In order to get a better perception off its meaning and role in today’s technological omnipresence, we present a short description of its history followed by an analysis of the concept’s characteristics, service models and deployment models. As typical as it may sound, we could not disregard the importance of the concept’s advantages and disadvantages. Further, we explain the significance of cloud storage especially for businesses, as well as its positive and negative consequences. As this form of data storage may provoke security issues related to the availability and integrity of data, we pay special attention to the nature of those issues. The third chapter is intended to emphasize the problem of data integrity in general and offer an idea for a solution that may be applied on files stored in cloud storage. The solution will be specialized on checking a remote file’s integrity and consistency. The next chapter presents the programming implementation of the suggested solution and evaluates the testing results of the program. This evaluation is used as a ground for laying our conclusions in the final chapter, as well as our propositions for some unaccomplished ideas that may be realized in a future work.
