Codis

The Combined DNA Index System (CODIS) is the United States national DNA database created and maintained by the Federal Bureau of Investigation. CODIS consists of three levels of information: Local DNA Index Systems (LDIS), where DNA profiles originate; State DNA Index Systems (SDIS), which allows for laboratories within states to share information; and the National DNA Index System (NDIS), which will enable states to compare DNA information with one another. The CODIS software contains multiple databases depending on the type of information being searched against. Examples of these databases include missing persons, convicted offenders, and forensic samples collected from crime scenes. Each state and the federal system has different laws for the collection, upload, and analysis of information contained within their database. However, for privacy reasons, the CODIS database does not contain any personal identifying information, such as the name associated with the DNA profile. The uploading agency is notified of any hits to their samples and is responsible for disseminating personal information in accordance with their laws.
