Uslugi teleopieki zdrowotnej to nowoczesne praktyki medyczne, które wykorzystują telekomunikację do zdalnego diagnozowania, leczenia i monitorowania pacjentów. Dostęp do tych uslug dla lokalnych i globalnych uslug opieki zdrowotnej za pośrednictwem niezabezpieczonych sieci publicznych stanowi ogromne zagrożenie dla bezpieczeństwa poufnych informacji pacjentów. Niniejsza praca ma na celu zabezpieczenie poufnych informacji pacjentów. Spośród różnych istniejących technik ukrywania danych, takich jak szyfrowanie, steganografia, znak wodny itp., steganografia zostala przyjęta w celu ukrycia poufnych informacji pacjentów w mniej wrażliwych cechach sygnalu maskującego bez zaklócania jego morfologii. Oprócz różnych obrazów medycznych i sygnalów fizjologicznych, jako skuteczny nośnik do ukrywania poufnych informacji, sygnal elektrokardiogramu (EKG) jest wykorzystywany jako sygnal maskujący do steganografii. Do ukrywania poufnych informacji w sygnale EKG zaproponowano trzy różne techniki w domenie przestrzennej, domenie częstotliwości i polączonej domenie przestrzenno-częstotliwościowej. Wszystkie trzy techniki z powodzeniem osiągnęly podstawowe atrybuty steganografii, tj. odpornośc, niepostrzegalnośc i zdolnośc do osadzania.
