Historically, two-factor authentication is not a new concept but its use has become far more prevalent with the digital age we now live in. As recently as February 2011 Google announced two factor authentication, online for their users, followed by MSN and Yahoo.
Body worn video (BWV), also known as body cameras, is a video recording system that is typically utilized by law enforcement to record their interactions with the public or gather video evidence at crime scenes, and has been known to increase both officer and citizen accountability.
With video evidence from body-worn cameras, police leaders and justice officials would have a new tool to validate eye-witness accounts and receive an unbiased detail of events. Many police forces are highly motivated to use body-worn cameras to reduce complaints against officers. They trust that some complaints can be resolved by viewing video footage to establish the facts. If the claims are true, law enforcement agencies can use video footage to help re-train officers.
