Co-utility

This book explores the theoretical foundations of co-utility as well as its application to a number of areas, including distributed reputation management, anonymous keyword search, collaborative data anonymization, digital oblivion, peer-to-peer (P2P) content distribution, ridesharing for sustainable mobility, environmental economy, business model design and the collaborative economy. It evolved from presentations at the 1st Co-Utility Workshop, "held in Tarragona, Spain, on March 1011, 2016."
How can we guarantee that a global society without a common legal framework operates smoothly? If generosity, honesty and helpfulness do not arise spontaneously, one approach would be to design transactions so that helping others remains the best rational option. This is precisely the goal of co-utility, which can be defined in game-theoretic terms as any interaction between peers in which the best option for a player to maximize her or his utility is to make sure the other players also enjoy a fair share of utility (for example, functionality, security or privacy). Therefore, a protocol or mechanism designed using the co-utility principle ensures that helping others is the best rational option, even if players are selfish.

Covers the theory, applications, and ethical aspects of co-utility Includes distributed reputation systems over the Internet, privacy in the information society, the collaborative economy, environmental economy, and smart mobility Introduces co-utility as the rational cooperation among rational agents that are part of distributed systems, and who are involved in games where the best strategy for each agent is to help another agent achieve his or her best outcome Evolved from presentations at the 1st Co-Utility Workshop, held in Tarragona, Spain, on March 1011, 2016 Includes supplementary material: sn.pub/extras
