A blind signature-based protocol for tracing traitors

Abstract

We introduce a protocol based on blind signatures using elliptic curves that allows to trace those users of any service, traitors, that share their legitimate license with other people, avoiding the abuse or the unauthorized use of legal licenses. We show that our protocol is incapable of implicating innocent users in the illegal distribution of licenses and that tracing produces indisputable proof for the implication of the traitors. We also show that our protocol provides anonymity to users unless they share their private information and compare it to other existing schemes. We also provide an implementation showing its practical application.

Intelligent System to Find the Health Care Centers for Senior Citizens Based on Disease and Nearest Locations using GPS

“…A concept of a mobile medical facility search functionality for elderly people based on venue. This system, whereas, is effectively implemented by the Bluetooth feature and the gyroscope (data link layers and physical layers) and GPS installed on the smart phone (transport layer), that will then enforce the actual service for senior citizens residing alone via its intelligent Java-based mobile medical facility search application (application layer) [15]. A mobile medical facility regional system depending on the level and illness of the patient is proposed in this section.…”

New computational and statistical models in science and economics

“…Álvarez et al [5] introduce a protocol based on blind signatures using elliptic curves that allows tracing those users of any service that share their legitimate licence with other people; this avoids the abuse or the unauthorized use of legal licences. The paper also provides an implementation showing its practical application.…”
