With the rapid development of multimedia exchanges, it is necessary to dispose secure systems to protect data and ensure the security of transfer. Two encryption schemes are proposed in this letter where the second is obtained by a simple modification on the first. The construction of the proposed schemes is based on the Singular Values Decomposition (SVD) which allows us to compress data by eliminating a number of singular values. So by these schemes instead to send an encrypted image, we send a set of three or six encrypting images. Both of schemes are applied on (PNG) images in different levels and their efficiency is tested by calculating MSE, NPSR and MAE. Numerical results and the reconstructed images are discussed
