an alternative approach to security concerns in digital library initiatives

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.
