The BioCTS suite checks that the record of an iris image or other piece of biometric data being used has the correct data and in the order called for by the standard, so that it can be sent to and received correctly and filed accurately by any user, from the Homeland Security Department to state and local police departments. The conformance testing provides programmers, users and product purchasers with an increased level of confidence in product compliance and increases the probability of successful interoperability.
The tests do not ensure interoperability of different products, however; only that they adhere to common standards, Podio said. “Conformance increases the probability of interoperability, but cannot ensure it because of all the possible implementations that can be included” in a product. Each developer can implement different profiles from the standard, depending on how the product will be used.
