In this paper, new information security algorithms using a rossler chaotic function are suggested, which contain image encryption, data encryption and data hiding. In designing the image encryption algorithm, a chaotic block was used to change the pixels value using the target pixels in each block. The experiments show that the system performance is improved and the cipher image characteristics are enhanced. Where, in the data encryption algorithm N x N blocks were used to encrypt the text files, so each character in the file will represent one generated block.
