The goal of Phase 2 will be to build a detector that can reliably detect the signature identified in phase 1 with high sensitivity and specificity.

to determine, by means of a well-developed scientific methodology, whether there are unique signatures in emanations that can be used to identify and distinguish specific high-level-of-interest individuals within groups of enemy troops or combatants, and if so, to develop enabling technology for detecting and identifying those specific signatures. The program consists of an interdisciplinary team of performers using state-of-the-art techniques to evaluate the statistical, biological and chemical nature of individual emanations. Once the nature of the chemosignal has been characterized, performers will determine the impact of non-genetic factors (e.g., diet, stress, health, age) on the signal in order to determine whether the signal can be robustly extracted from a complex and varied chemical background. If an exploitable robust signature is identified, the program will then pursue detector development.

a field study was planned and conducted by RTI. In this study, identical twins and a family member (sibling or parent) were recruited. Each group went to either Williamsburg, VA, or Research Triangle Park, NC, for a four-day stay at a hotel. During this stay, daily sweat samples were collected onto polydimethylsiloxane membranes, as described in earlier reports to DARPA/ARO. A total of seven sets of twins were recruited. The goal was 30 twin pairs. Given the relatively poor response rate and the need for project resources to adequately address the data processing and statistical analysis needs of the overall USD program, the field study was terminated.

Scharlette Holdman, then director of the Hawai'i ACLU, sought entry to a prison and was searched by a matron who discovered Holdman was not wearing a bra. The matron denied Holdman entry, relying upon a directive that required visitors to be 'properly dressed,' 'fully clothed including undergarments,' and stated 'provocative attire is discouraged.' Holdman's challenge stressed equal protection, under both the United States and Hawai'i state constitutions, arguing that the requirement that women wear bras while men need not constituted sex discrimination. Writing in 1978, the Hawai'i Supreme Court expressed some consternation about the slight record, but relying in part on deference to prison officials, the court found that dress standards are 'intimately related to sexual attitudes' and 'the omission of a brassiere as a conventional article of women's clothing' has been 'regarded as sexually provocative by some members of society.' ... The fact that Scharlette Holdman's lack of a bra became evident only upon a tactile search was irrelevant: the prison could still find it would be sexually provocative to the male inmates.
