Use of facial composite systems in US law enforcement agencies

Abstract

Facial composite images are often used in the criminal investigation process to facilitate the search for and identification of someone who has committed a crime. Since the use of facial composite images is sometimes relied upon as an integral part of an investigation, it is important to ascertain information about the various decisions made and procedures implemented by law enforcement regarding the use of composites. A 39-item survey was developed to examine the prevalence of a number of procedures related to composite production, including the systems implemented, criteria for selecting systems, law enforcement training, satisfaction with systems, legal challenges, and procedural issues with respect to interviewing multiple witnesses and the distribution of composite images. Surveys were distributed to 1637 city, state and county law enforcement agencies nationwide; 163 completed surveys were returned. This paper summarizes our survey results and discusses the implications for investigative procedures, law enforcement training, and future research needs.     

Say cheese! Privacy and facial recognition

The popular social networking site, Facebook, recently launched a facial recognition tool to help users tag photographs they uploaded to Facebook. This generated significant controversy, arising as much as anything, from the company’s failure to adequately inform users of this new service and to explain how the technology works.The incident illustrates the sensitivity of facial recognition technology and the potential conflict with data privacy laws. However, facial recognition has been around for some time and is used by businesses and public organisations for a variety of purposes – primarily in relation to law enforcement, border control, photo editing and social networking. There are also indications that the technology could be used by commercial entities for marketing purposes in the future.This article considers the technology, its practical applications and the manner in which European data protection laws regulate its use. In particular, how much control should we have over our own image? What uses of this technology are, and are not, acceptable? Ultimately, does European data protection law provide an adequate framework for this technology? Is it a framework which protects the privacy of individuals without unduly constraining the development of innovative and beneficial applications and business models?
