SECURE DATA SHARING MODEL FOR PRESERVING PRIVACY

摘要

Data sharing is the process of interchanging, analyzing, retrieving and integrating data. Although data sharing facilitates the way that data can be exchanged, security concerns arise as a challenge for conducting data sharing. Many policies include confidentiality, integrity, availability and privacy must be taken into consideration. In this research, preserving privacy subject will be considered. This research will propose a new privacy preserving data sharing model that combines compression techniques such as Huffman coding and different encryption algorithms in order to provide privacy in data sharing to facilitate data sharing in different areas. Performance parameters, such as processing and transfer time, and the enhancement for the expected model are also considered. Experiments results over 10 different files sizes show that the proposed model provide privacy to shared files also it reduces large files size since the proposed model uses Huffman coding and it is 87% faster on speed of 1MB/sec and on speed of 16MB/sec it is 38% faster than existing models.
