The analyst bows, and says, "We use very sophisticated algorithms to conduct comparative evaluations, Machiko-san. These algorithms take into account a variety of biodynamic factors such as anatomical structure and its influence on physical motion. A person's face may be easily modified, or, as in this case, largely concealed. How a person walks, however, is not so easily disguised. An analysis of this type is not as precise as one might obtain from genetics, or even fingerprints, but it is generally able to provide a reliable indication. It would perhaps be more precise to say that the mage from the hotel record moves in a manner highly consistent with the individual, called Gamma, in the digipics you have provided."
