Data steganography is one of the most popular methods of data protection, but most introduced methods are not secure. In this paper research a simplified LSB method of data steganography will produced, this method will easily used to hide any message in any covering image, changing the image or/and changing the message will not require any changes in the algorithm. The proposed method will use a complicated key to select a secret block from the covering image to be used to hide the message. The PK will contain 5 components of double data type, thus the PK will provide a huge key space which is capable to resist any hacking attempt, the algorithm of the proposed method will be very sensitive to the PK values, any changes in these values will be considered as a hacking attempt by producing unexpected outputs. The proposed method will be implemented and tested using various messages, various covering images, and various PK; the obtained results will be analyzed applying sensitivity analysis, quality analysis and security analysis to prove the improvements added to LSB method of data steganography.
