One variation of a method for securing synthetic video conference feeds includes, during a setup period: accessing a target image depicting a face of a user; generating a face model based on a target set of facial features detected in the target image; and linking the face model to a target set of facial biometric values of the user. The method also includes, during an operating period succeeding the setup period: accessing a frame; deriving characteristics of a set of facial features detected in the frame; extracting a set of facial biometric values from the frame; in response to alignment between the target set of facial biometric values and the set of facial biometric values, generating a synthetic face image based on characteristics of the set of facial features, the face model, and a synthetic face generator; and rendering the synthetic face image in place of the frame.
