Applied DNA Sciences Presents "SigNature DNA Embedment and Authentication for Secure Documents" at the Future of Secure Documents Conference.

STONY BROOK, N.Y. -- Applied DNA Sciences, Inc. (OTC Bulletin Board: APDN), a DNA security solutions company, today announced that Dr. James A. Hayward, Chief Executive Officer, presented at The Future of Secure Documents Conference held April 18-19 in Orlando, FL.

Counterfeiting and tampering represent a huge risk for high value documents throughout the world. The secure documents market is constantly striving to develop new technologies attempting to stay one step ahead of the counterfeiters. Governments and private companies continue to search for ways to make banknotes, passports, ID cards and credit cards more secure. In 2005, DOPIP estimated that seizures and losses associated with counterfeit currency were approximately $609 million in the U.S. alone. Additionally, they estimate that counterfeit identity seizures and losses were approximately $124 million in that year.

Dr. Hayward's talk, entitled "SigNature DNA Embedment and Authentication for Secure Documents," addressed this disturbing trend and presented the use of DNA embedment to combat counterfeiting in secure documents. DNA embedment offers a broadly applicable, convenient and inexpensive way to help protect currency, passports, driver's licenses, credit cards and other documents from counterfeiting. APDN's platform for DNA embedment, uses unique DNA "chimers", is derived from botanical sources, and is marketed as the "SigNature" brand. The SigNature DNA Markers are highly resistant to reverse engineering or replication, and can either be applied independently or to supplement other security taggants in order to allow for a forensic level of authentication. APDN's SigNature DNA Markers can easily be integrated with RFIDs, optical memory cards, intaglio inks, adhesives, dyes, watermarks, barcodes, security threads and other security measures in use today, adding an additional layer of security which is difficult to overcome. APDN also offers SigNature DNA Ink, which is highly durable and degradation resistant and can be visible or invisible.

"Counterfeiting is a rapidly growing problem which threatens the safety and well being of people everywhere," Dr. Hayward stated. "APDN's SigNature Program can quickly and reliably authenticate and identify counterfeit versions of secure documents, enabling companies to detect, deter, interdict and prosecute counterfeiting enterprises and individuals. This conference presented a wonderful opportunity to introduce the potential power of our DNA technology as both a way to deter counterfeiting and help protect secure documents and thus people throughout the world."
