A health in personal care medical sensor according to the present invention system for a device, various kinds of sensors; sensing from said sensor an encoded data encryption signal accepted from the simultaneous reproducing unit; said encryption unit typically stays in low force and providing encryption key an encryption key generating part; said encrypted transmission to the server hospital circuit block includes a variable a communication module; the nozzle is extended from the end, said encryption key generating part a, has a bit length La key while linear feedback series-connected to the discharge transistor output a linear feedback mobile register; bit length pound series-connected to the discharge transistor key has a non-linear output while feedback nonlinear feedback mobile register; a memory that stores progression feedback and; mobile linear feedback said mobile feedback nonlinear said register and said register and an initialization is returned via a memory the graphic signal processing part converts the nonlinear as a function for generating an encryption key processing module nonlinear function; is characterised in that composed.
