Exchange of information through the channels of communication can be
unsafe. Communication media are not safe to send sensitive information so it is
necessary to provide the protection of information from disclosure to unauthorized
persons. This research presented the method to information security is done
through information hiding into the cover image using a least significant bit (LSB)
technique, where a text file is encrypted using a secret sharing scheme. Then,
generating positions to hiding information in a random manner of cover image,
which is difficult to predict hiding in the image-by-image analysis or statistical
analyzes. Where it provides two levels of information security through encryption
of a text file using the secret sharing and the generating random positions of hiding.
This method has been in hiding a text file and recovered without loss of
information, as well as not noticing any deformation of the image. Where it was
hiding a text file size of 20 KB in image cover (250x250) pixels, the result of MSE
is 0.696 and PSNR is 49.211.
