Abstract

Digital preservation refers to an important aspect that most Iranian digital library initiatives lack. This component is Security. While a digital library may be misconceived as an information supply space without a physical form, the same security concerns in force for operation of physical library are valid. Unlike the analog materials, all digital copies of digital materials are original. A digital library can provide a tool whereby the user can authenticate the same material without compromising sensitive watermark key data. Watermarks must be impervious to premeditated alterations and tampering. A national digital watermark assignment center is proposed for sharing the burden of development and distribution of such security features to content developers.
