This paper describes the methods to increase the capacity of the cover image for information hiding. In this paper we have proposed three novel multiple least significant bit replacement techniques KIMLA and KAMLA and KAMLAC to increase the information hiding capacity of the cover image. Comparative results of KIMLA, KAMLA, KAMLAC and their previous version KMLA [1] are also shown. These novel techniques use multiple LSB’S bit replacement technique to hide the secret information. The proposed methods KAMLA and KIMLA and KAMLAC have shown better results for AFCPV, PBC ratios and they have been tested for secret information in image as well as text form.
