Abstract: With the explosive expansion of big data, personal data has become important resource of data industry. The indiscriminate collection of personal data, data abuse, and widespread black market transactions make the protection of personal data privacy become a very pressing issue. In this context, we make a close study of privacy protection of personal data. For the particular characteristics of privacy leakage, we investigate the sources and the pathways of personal data, to obtain the model of data collection, data transmission, data diffusion and data derivatives. Then we present privacy protection reference architecture for personal data under information propagation, composed of technology, management, and legal regulations. Furthermore, we present the future study issue, namely privacy protection reference architecture for personal data under data mining.

Key words: big data, personal data, privacy protection, information propagation, data mining
