Digital forgery is very common these days because the use of digital document is increasing day by day and readily available software’s for manipulating the documents. It is very necessary to authenticate the integrity of digital document, whether it’s genuine or not. Various secure detection systems are made which involves use of algorithm, but this paper deals with examining simple features present in image/document which can be used to check the authenticity of an electronic document, whether they are genuine or forged. These simple features are like Color variation, Font size difference, Pixelate resolution, Range of magnification-low, medium and high range of magnification and extracting hash value-MD4, MD5, SHA-1, RIPEMD-128 and RIPEMD-160. Results are highly reliable.
