Research on Unified Representation and Storage of User Log in eID Based Virtual Property Preservation System

The Virtual Property Preservation System [1] based on eID involves lots of different types of application platforms, such as taobao.com, jd.com, weibo, etc. Users log will be generated in these application platforms. Different platforms have different log formats and management systems. Besides, these management systems are completely isolated. But in reality, the user's behavior is often complex, users can operate on multiple application platforms in a short period of time. To obtain a user’s complete network behavior from user log is of great importance to virtual property audit traceability, abnormal finding of the Virtual Property Preservation System. So the unified representation and storage of the cross-platform user log is necessary. We provide a unified representation method to put user logs on different platforms together. Based on the early research on eID Virtual Identity Data Storage [2] of Han, one of the authors of this paper, We analysis the data characteristics of cross-platform user log and provide a
