Integrated Data Systems (IDSs) link individual-level data from multiple agencies, such as schools, juvenile justice agencies, and human services agencies, often with a focus on children. The systems can be used for a variety of purposes, including case management or program monitoring and evaluation. By linking data across public agencies, redundant data collection can be minimized, while the ability to utilize the information to improve programs and services for the community is maximized.

In this paper, we refer to disclosure as encompassing any of the following:

• Identity disclosure: when a subject’s identity can be identified in a data record containing confidential information
• Attribute disclosure: when a sensitive attribute of a subject’s identity is revealed from a data release
• Inferential disclosure: when released data make it more likely that the consumer of the data release can identify or determine an attribute of a subject in the data
