摘要： A system allowing a participant (101) to participate anonymously in a plurality of sessions but to be detected that the same participant has participated more than once in the same session is disclosed. The participant authorizes individual data (12) using secret information depending on session-related information (11). The reception subsystem (102) determines Whether received data is anonymous participation data authorized by the participant subsystem and further determines whether anonymous signatures of arbitrary two pieces of anonymous participation data are signed by an identical participant subsystem. The anonymous signature may include data generated by raising a session-dependent base to a power dependent on the secret information.

摘要： Disclosed is a multi-purpose transaction card system comprising an issuer (101), one or more cards (102), one or more terminals (103), and optionally one or more acquirers (104), communicating using a variety of cryptographic confidentiality and authentication methods. Cards authenticate messages using public-key based cryptographic without themselves performing the extensive computations usually associated with such cryptography. Integrity of complex transaction sequences and plural card storage updates are maintained, even under intentionally generated interruptions and/or modifications of data transmitted between card and terminal. Cards do not reveal any information to the terminal which is not directly necessary for the transaction or any information to which the terminal should not have access, through externally measureable aspects of its behaviour. Transaction types supported include those suitable for off-line credit cards, in which the 'open to buy' is maintained on the card.

摘要： In an electronic cash implementing method, a user makes a bank apply a blind signature to user information Vi produced, by a one-way function, from secret information Si containing identification information, thereby obtaining signed user information. Further, the user makes the bank apply a blind signature to information containing authentication information Xi produced, by a one-way function, from random information Ri, thereby obtaining signed authentication information. The user (200) uses an information group containing the signed user information, the signed authentication information, the user information and the authentication information, as electronic cash for payment to a shop. The shop (300) verifies the validity of the signed user information and the signed authentication information, and produces and sends to the user an inquiry. In response to the inquiry the user produces a response Yi by using secret information and random information and sends it to the shop. Having verified the validity of the response the shop accepts the electronic cash.

摘要： A system and method for reliably and securely recording and storing all attributes of data, such as for the identification and authorization of individual identity as well as attributes relating to it and personal data including but not limited to individual's physical description, bank details, travel history, etc. (the "Personally Identifiable Information "ΡΠ"). PII can be difficult to manage in networks where correlation between data sources is required. Thus, in some embodiments, the system combines a distributed database to create a framework for a robust security. The system manages the distributed database to associate transactions, or actions, using data, digital signatures, and/or cryptographic keys, which can be unique to an individual.

摘要： The invention relates to a method for the unique authentication of a user (U) by at least one service provider (SP), said method comprising the preliminary phase of federating identities between an identity (user@sp) of the user by said service provider and an identity (user@idp) of the user (U) by an identity provider (IdP). According to the invention, the preliminary identity federation phase comprises the following steps: for the user (U), generating an alias ([alias]) of the user for the service provider (SP) and transmitting to the identity provider (IdP) a masked alias ([alias]masqué) derived from the alias; for the identity provider (IdP), associating said masked alias ([alias]masqué) for this service provider (SP) with the user's identity (user@idp) by the identity provider (IdP), and transmitting elements to the user (U) so that the user can calculate a signature ( s ) of a message {msg) containing the unmasked alias ([alias]); for the user (U), calculating said signature ( s ) and transmitting to the service provider (SP) said message {msg) with said signature ( s ); and for the service provider (SP), checking said signature ( s ), authenticating the user (U) and associating said alias ([alias]) with the user's identity (user@sp) by the service provider (SP).
摘要翻译：本发明涉及一种用于由至少一个服务提供商（SP）对用户（U）的唯一认证的方法，所述方法包括由所述服务提供商（SP）在用户的身份（用户@ sp）之间的联合身份的初步阶段以及身份提供者（IdP）的用户（U）的身份（user @ idp）。根据本发明，初步身份联合阶段包括以下步骤：对于用户（U），为服务提供商（SP）生成用户的别名（[别名））并向身份提供商（IdP）a发送来自别名的蒙版别名（[alias]masqué）对于身份提供商（IdP），通过身份提供者（IdP）将用于该服务提供商（SP）的所述被屏蔽的别名（[alias]masqué）与用户的身份（user @ idp）相关联，并向用户（U ），使得用户可以计算包含未屏蔽的别名（[alias]）的消息{msg）的签名; 对于用户（U），计算所述签名并且向所述服务提供商（SP）发送具有所述签名的所述消息（msg）; 并且对于服务提供商（SP），检查所述签名，认证用户（U）并且将所述别名（[别名））与服务提供商（SP）的用户身份（user @ sp）相关联。
