The Illusion of Anonymity

Dealing with confidential data on the web

Regardless of the database architecture or specific product, all data audits must capture the following information:

Who – A full identification of the person viewing or modifying the data.

Where – A log showing the specific application procedure and method used to access the data.

When – A reliable date-time-stamp, globalized to Greenwich Mean Time (GMT).

What – A full listing of all data entities that were viewed or modified.

Why – Context-based information describing how the data was disclosed.

These web-based database systems have extremely complex and complete auditing mechanisms, but they remain vulnerable to outside hacker attacks.

Figure 1.1An example of a data access structure and its vulnerable points


As shown in Figure 1.1, there are many ways that web hackers can obtain confidential information.  In addition, internal disclosure of private information is also a potential problem.  This is especially important for online health care databases.  Successful web companies apply sophisticated filters to the audit trails at data capture time to spot suspicious trends and patterns in data access, as in Figure 1.2.
