摘要：With the advance in the electronic devices, digital publications become more and morepopular in our life. However, the properties of digital contents make themselves be easilycopied and transferred if there is not any proper protection for them. Hence, it is a criticalissue for publication provider to e.ectively control and distribute their digital publications.Digital Rights Management is a mechanism, which might congregate various techniques toprotect the rights of digital publication from copyrights violations. Moreover, Wrapper-basedDigital Rights Management technique applies encapsulating digital contents by packagingcontent and monitoring by API-Hook to control and protect them, which provide a way toauthenticate users by users' machine serial number or smart card via network. Hence, usersmay use the digital contents without changing their digital content player. According to thedefinition of Digital Rights Management, this paper provides a digital publication issuingmechanism, which supports superdistribution for advertising digital publications e.ectivelyand improving development of digital contents

It;is essential to protect digital contents; which will improve the intention of digital contents;providers to create new products and protect the rights of legal customers.;Digital Rights Management (DRM) is a mechanism; which congregates hardware and soft-;ware to ensure the rights of digital publication providers against illegal usage [1].

However; some prevailing systems; such as Windows Media Rights Manager;iTunes; and Adobe Systems; only support their own digital content types. These systems;do not provide interoperability; which limits the usage of digital contents with many re-;strictions.;The concept and architecture of Superdistribution is proposed by Mori [2; 3] for building;up a software service system in a P2P structure. Superdistribution could also be a business;model; which distributes digital publications safely and e.ectively by combining some free;methods [4; 1].;There are some advantages would be obtained if DRM supports superdistribution; such as;progressing distribution channels; reducing distribution costs; and forming strong partner;networks. In this paper; we will adopt Windows32 API hooking for it is more inexpensive;than designing DRM system with expensive hardware. Under the assumption of payment;.ow has been well implemented; we implement the DMR system on Windows 32-bit plat-;form. The rest of this paper is organized as follows. We review the DRM model in Section;2. In Section 3; we propose a novel wrapper-based digital publication issuing mechanism.;In Section 4; the comparison with other related works are presented. Finally; a conclusion;is presented in Section 5.;2 Related Works;DRM [4; 5; 6; 7; 8] is a mechanism; which congregates various techniques for protecting;the rights of digital publication providers. It provides the functions of content protection;process monitor; and tracing user records. To maintain interest and friendly relationships;between digital contents providers and products customers; DRM needs to support dig-;ital publication transaction; rights transferring; and digital publication delivery. It also;needs to describe and identify the digital publication in a digital publication transac-;tion. Hence; the roles involved in a transaction of the traditional DRM model are content;owner; distributor; license broker; and user [1; 4; 7]. However; some recent researches of;DRM [7; 9; 10; 11; 12; 13; 14; 15; 16; 17; 18; 19; 20; 21; 22; 23] focused on ontology researches;for rights description [17; 23]; integration and interoperation research [7; 9]; constraints pro-;totype [18]; privacy protection [20; 21]; implementation [12; 14; 15]; and business model;such as superdistribution [3; 10] and o.ine distribution [19; 22].;In 2005; Yang proposed a design of multimedia digital rights management mechanism based;on XrML [14]. Yang's mechanism focused on the business model using grant of rights to;form various business models; which adopted Windows Media Rights Manager and only;supported some kinds of media. Moreover; it does not support o.ine authorization and;rights transferring.;In 2007; A digital publication right issuing management practice mechanism was proposed;by Liaw et al. [15]. Their mechanism provided a complete digital rights management process;design. However; it does not support o.ine tracking; rights transferring; rights revoking;and superdistribution. In the same year; Sun et al. proposed an improved digital rights;management system based on smart cards [13]. They improved some disadvantages of;privacy in an identity-based DRM system proposed by Conrado [20]. Their system retains;users' privacy by removing relationship between users and digital publications and protects;digital production by using secure memory. However; their system is not a DRM system;International;Journal;of Hybrid;Information;Technology;Vol.;6;No.1;January;2013;94
