In this paper, the authors accomplishment and study of image steganographic procedure is carried out to insure security of the data on cloud. LSB encoding technique is utilized to hide the data in last 4 LSBs of 24 bit RGB pixels of colored cover image. The intermediate cover image containing the data (stegano image) shows a good correlation with the original cover image meaning a good amount of hiding of data. If the size of the data file to be sent is more than the capacity of the cover image then multiple copies of cover image are used to embed the data.
