Study on the Countermeasure of Security Problems of Big Data Caused by Data Fragmentation

The analysis and application of big data has become the frontier science at this era. People make universal attentions on the values that are existing or potential brought by the application of big data, but they make little attentions on the security threats behind the application of big data. At present, some researches have realized the security threats generated by the data leakage, its significance is not less than the application of big data. In this article, we put forward the security problems of data leakage caused by data fragmentation of big data, we also put forward some corresponding solutions and mathematical models, and finally, we conduct theory verification through the actual cases, which can effectively prevent the security problems of data leakage caused by data fragmentation.The analysis and application of big data has become the frontier science at this era.
