Systems and methods are described, and an example system creates a transaction between a biometric station and a user in a group of users. Transaction includes establishing for the user, a ground-truth identity, capturing an image of the user in the biometric station, making a first determination of whether the image is sufficient for identification of the user. When the image is sufficient, the transaction derives biometric information from the image, converts the biometric information into a generic-form biometric information, agnostic of how the biometric information was obtained, and generated hashed user data by applying a hash function to the generic-form biometric information. The transaction makes a second determination, based on the hashed user data, of whether the user is represented in a gallery of sample images. The transactions are repeated for other users in the group. In the repeats, when the image is determined sufficient, another second determination is made, generating a plurality of second determinations. An acquisition quotient is calculated for the plurality of second determinations, based on one of efficiency, effectiveness, and accuracy relative to time.
