Abstract:
1. A privacy system for processing data obtained from an input signal comprising physiological information derived from radiation reflected by a person, the physiological information being representative of at least one vital signal of the person, the system comprising: a detector configured to detect at least one vital signature in the input signal, wherein the input signal comprises a continuous or discrete sequence of image frames related to a specific signal space, the at least one vital signature varying over time and corresponding to variations of the at least one vital signal, and wherein the at least one vital signal is obtained from variations of skin color over time; and a converter configured to create an output signal by modifying the input signal depending on the detected vital signature, wherein the output signal comprises an artificial signature at least partially replacing a respective vital signature portion of the at least one vital signature of the input signal.
