The vision of N-DEx is to enable the sharing of complete, accurate, timely, and useful information across jurisdictional boundaries and to provide new investigative tools that enhance the nation’s ability to fight crime and terrorism.
N-DEx provides law enforcement agencies with a powerful new investigative tool to search, link, analyze, and share criminal justice information such as incident/case reports, incarceration data, and parole/probation data on a national basis to a degree never before possible.
What is N-DEx and What Are Its Benefits?
N-DEx is a criminal justice information sharing system that provides nationwide connectivity to disparate local, state, tribal, and federal systems for the exchange of information. N-DEx provides law enforcement agencies with a powerful new investigative tool to search, link, analyze, and share information (for example, incident and case reports) on a national basis to a degree never before possible. N-DEx benefits local law enforcement in their role as the first line of defense against crime and terrorism.
Through N-DEx’s services and capabilities, N-DEx allows participating agencies to detect relationships between people, places, things, and crime characteristics; to link information across jurisdictions; and to “connect the dots” between apparently unrelated data without causing information overload. This capability occurs primarily in the realm of structured data but can also include unstructured data. In addition, N-DEx provides contact information and collaboration tools for law enforcement agencies that are working on cases of mutual interest.
Ownership of data shared through N-DEx remains with the law enforcement agency that provided it. N-DEx supplies controls to allow law enforcement agencies to decide what data to share, who can access it, and under what circumstances. It allows agencies to participate in accordance with applicable laws and policies governing dissemination and privacy.
Although law enforcement is the primary focus of N-DEx, future iterations will incorporate the full criminal justice community. The ultimate goal is to transform all criminal justice data into knowledge for the entire justice community.
N-DEx offers a range of options to allow broad participation, ranging the spectrum from law enforcement agencies with automated records management systems to those with paper-based systems.
To mitigate law enforcement agencies’ costs and impacts, N-DEx uses nationally-developed standards and existing systems and networks. N-DEx also helps agencies get started by providing implementation support, tools, and training.
The N-DEx concept was developed in close collaboration with the local, state, tribal, and federal law enforcement agencies critical to the success of the project. Ensuring that N-DEx meets the real-world needs of law enforcement has been identified as the key success of the factor from the very beginning and will continue to guide the program throughout implementation and operation.
What is the timeline for the N-DEx development?
