Abstract: This work proposes a secure user-centric attestation service (SUCAS) framework that enables user of location-based services to create, share, and verify spatial-temporal evidence incorporated with user's action information using tamper-resistant device such as the smart-card. The generated evidences can be used for protecting the owner's rights in times of need. The SUCAS framework preserves user's privacy by granting control to the user while protecting the integrity and authenticity of the evidences by using tamper-resistant device. The SUCAS protocol covers the process for evidence generation, evidence attestation, evidence sharing and evidence verification. A train delay certificate application was developed to evaluate the SUCAS framework. The results indicate that the evidences generated by SUCAS are trustable, verifiable and adhere to user's privacy. Furthermore, the SUCAS framework can be applied to other applications that require attestation services provisioning. Attestation service has great potential in the information age as it provides a mechanism to certify the reliability of digital information.
