This paper proposes a visible watermarking scheme using Discrete Fourier Transformation and which is reversible with some additional information. In the proposed scheme follows one to one mapping between the DFT coefficient of the cover image and watermark. For the purpose of our scheme the watermark of different size is embedded into the standard test images. Experimental results shows that the watermarked image has good perceptible features and authorised user can recover the original cover
