CRYPTOGRAPHIC METHOD FOR DIGITAL DOCUMENT
Journal Title: International Journal of Computer Science & Engineering Technology - Year 2016, Vol 7, Issue 6
Abstract
Due to the recent development of computers and computer networks, huge amount of digital data can easily be transmitted or stored. However, transmitted data in networks or stored data in computers may easily substitute by enemies Therefore; security is one of the most important technologies in computerized society. Hence, an authentication method based on secret sharing scheme via PNG image and bin mapping is proposed to authenticate the digital document images. In these proposed method, an authentication data is created for each block of document image which is transformed into several secret shares using Shamir’s secret sharing scheme and then embedded into the alpha channel plane. Then the alpha channel plane is combined with the original cover image to form a PNG image. In verifying the integrity of the image the authentication signals are computed from the current block which is then compared with the extracted shares from the alpha channel plane for the respective block. If the authentication data are not match then that block is marked as tampered block and repaired by reverse secret sharing scheme.
