A federal grant, the first in the nation to be awarded, is bringing state-of-the-art technology to Davidson County’s efforts to keep track of convicted sex offenders.
The iris biometric grant, from the National Sheriffs’ Association’s, funded the installation of new technology that positively determines the identity of an individual by capturing a high-resolution digital photograph of an individual’s iris.
According to Sheriff Daron Hall, the equipment will be used to document sex offenders who come to the sheriff’s office to register. The data from these individuals will be collected and included in a national database.
Additionally, the information may assist in identifying when an offender is wanted in another jurisdiction.
The iris scan system, valued at $10,000, is non-intrusive. Simply looking into the camera captures an image of the iris, and the extremely accurate technology can tell the difference between twins or even an individual’s right and left eye.
“I am particularly pleased that the Davidson County Sheriff's Office has been chosen by the National Sheriffs’ Association to be one of the first grant recipients in the nation of this iris scan machine,” Hall said. “It is the sheriff’s office’s responsibility to gather information on sex offenders when they come to register in this county. Including them in an iris scan database is a great step because you can never be mistaken for someone else and you can share the data electronically with other law enforcement agencies.”
