SPIES Protocol: Economic Incentives for Protecting Digital Rights Online

In today's digital world, protecting electronic content from unauthorized sharing is crucial to prevent economic harm to content owners. This paper introduces the Secret Protection Incentive-based Escrow System (SPIES), a protocol designed to limit illegitimate sharing and preserve digital rights. By leveraging game theory and methods like DRM, SPIES aims to incentivize legitimate sharing while deterring unauthorized access. The protocol defines the exchange and protection periods, offering a practical solution for content providers, consumers, and escrow services. The SPIES protocol can be applied to various scenarios, such as password protection, corporate knowledge sharing, and pre-release media, with the goal of minimizing unauthorized sharing and ensuring fair distribution of digital content.

  4. Background&Related work(1/2) • Game theory • Digital rights management (DRM) • DRM is the use of technological means to allow only authorized uses of or access to content. • Traditional DRM uses techniques: encryption & watermarking • DRM-free

  5. Background&Related work(2/2) • Digital rights management (DRM) Content provider Content consumer Escrow service

  6. The proposed protocol (1/5) • Secret Protection Incentive-based Escrow System (SPIES). • SPIES is best suited for applications in which the content is legitimately shared among a small set of participants. • SPIES should not be used to replace traditional DRM. (ex. movie and music files sold online) • SPIES used to limit unauthorized sharing of passwords for accessing content on websites.

  9. The proposed protocol (4/5) • Exchange period

  10. The proposed protocol (5/5) • Protection period Fig. the Bounty Payment

  11. Conclusions • SPIESuses the techniques of game theory to analyze strategies andoutcomes. • Applicable: passwords, corporate knowledge-sharing, pre-release media. • Its chief limitations are the requirements for a limited number of legitimate. • To limit and detect unauthorized sharing.
