    Resum:
    This thesis is about the research and development of privacy enhancing techniques to empower consumers of electronic commerce services with the control on how much private information they want to share with the service providers. We make use of known and newly developed technologies to protect users against excessive data collection by service providers in specific applications. Namely, we use a novel identity-based dynamic threshold signature scheme and a novel key management scheme to implement a group size accreditation mechanism, that does not reveal anything about group members but the size of the group, to support group discounts. Next, we use a novel construction based on blind signatures, zero-knowledge proofs and generalization techniques to implement a privacy-preserving loyalty programs construction. Finally, we use multiparty computation protocols to implement implicit authentication mechanisms that do not disclose private information about the users to the service providers.
