1. A multimodal biometric profiling system comprising: at least one hardware processor; and a memory storing machine readable instructions that when executed by the at least one hardware processor cause the at least one hardware processor to: receive a cover image and a biometric template for a person; receive an indication of a security requirement related to biometric profiling for the person; and determine a threshold value based on the indicated security requirement, wherein the threshold value is to limit a number of biometric template bits of the biometric template that are embedded in a predetermined bit position of a cover image pixel of the cover image based on cover image intensity associated with the predetermined bit position.
