本报告调查了几种生物识别决策形式的“决策景观”。讨论的问题包括：(i)估计与不同生物特征相关的自由度，作为衡量其模板的随机性和复杂性（以及因此的独特性）的一种方式。（二）将一项以上的生物特征测试结合起来作出决定的后果。需要通过大规模详尽的数据库搜索进行身份查验，而不是仅仅通过与单一模板进行比较进行核查。（iv）生物识别密钥加密的场景（使用生物识别技术对信息进行加密）。这里以抽象的形式考虑这些问题，但在适当的地方，使用虹膜识别的特定示例作为说明。所有四组问题的一个统一主题是组合复杂性的作用，及其测量，在确定生物识别决策的潜在决定性。
This report investigates the “decision landscapes” that characterize several forms of biometric decision making. The issues discussed include: (i) Estimating the degrees-of-freedom associated with different biometrics, as a way of measuring the randomness and complexity (and therefore the uniqueness) of their templates. (ii) The consequences of combining more than one biometric test to arrive at a decision. (iii) The requirements for performing identification by large-scale exhaustive database search, as opposed to mere verification by comparison against a single template. (iv) Scenarios for Biometric Key Cryptography (the use of biometrics for encryption of messages). These issues are considered here in abstract form, but where appropriate, the particular example of iris recognition is used as an illustration. A unifying theme of all four sets of issues is the role of combinatorial complexity, and its measurement, in determining the potential decisiveness of biometric decision making.
