The Illinois Biometric Information Privacy Act (740 ILCS 14/1), enacted in 2008, addresses biometric
data collected by private entities, but not governmental entities. Under the Act, biometric data may not be
collected or disclosed without the subject’s informed written consent, with few exceptions. The Act
obligates entities in possession of biometric data to make a public schedule and create guidelines for
destroying the data after the initial purpose for collection has been satisfied, or after three years, whichever
comes first. The Act notes that the ramifications of biometric technology are not fully known, yet the
definition of “biometric identifier” only includes the following: a retina or iris scan, fingerprint, voiceprint,
or scan of hand or face geometry. [Refer: Appendix A: references]
Indiana Code 4-1-6, Fair Information Practices; Privacy of Personal Information, addresses data
collected by governmental agencies, regulating the collection, maintenance and use of personal information.
“Personal information” is given a broad definition that encompasses biometric identifiers. The Code
restricts the collection of personal information to that which is relevant and necessary to accomplish a
statutory purpose, and directs state agencies to inform individuals regarding the use and confidentiality of
the information. The Code includes a right of data subjects to inspect, challenge, or correct their personal
Texas addresses biometric privacy in both its Government Code and Business and Commerce Code, thus
covering both the public and private sectors. Government Code Chapter 560, enacted in 2001, prohibits
government bodies from disclosing biometric data without the subject’s consent, and obligates these bodies
to securely store and protect biometric data. The Business and Commerce Code Chapter 503, enacted in
2007, requires informed consent for collecting and disclosing biometric data; obligates secure storage; and
requires disposal no later than one year after the data are no longer needed. “Biometric identifier” is defined
here as “a retina or iris scan, fingerprint, voiceprint, or record of hand or face geometry.”
Recent Technology Advances
It is important to understand the recent advances in the field of biometrics which make the technology more
practical and appropriate for use by airport operators. There have been recent significant developments that
are summarized as follows:
Biometric reader devices are smaller and lower in cost while being capable of increased matching
There are more commercially available choices of biometric hardware and software products.
Biometric matching performance is more accurate with fewer exception situations to manage.
Biometric devices are now commercially available that function well under extreme environments
including outdoor operations.
Evolving biometric standards support increased adoption and interoperability.
Many physical access control system providers now have formal programs that certify the
compatibility of biometric reader devices to their systems thereby simplifying and reducing the risk
of biometric implementation.
Biometrics have been incorporated into other US Government and international transportation and
Hand vein pattern recognition has become an accepted biometric modality for access control.
Non-contact fingerprint sensors are now commercially available and capable of rapidly capturing
multiple fingerprint images with the wave of hand across a scanning area.
