摘要： Embodiments of the present disclosure provide a method and system for guided implicit authentication. The system first receives a request to access the controlled resource from a user. The system then determines whether the user request is inconsistent with regular user behavior by calculating a user behavior measure derived from historical contextual data of past user events. Next, the system allows the user to provide information associated with regular user behavior and/or current contextual data. The system further updates the user behavior measure based on current contextual data.
摘要翻译：本公开的实施例提供了一种用于指导隐式认证的方法和系统。系统首先从用户接收到访问受控资源的请求。然后，系统通过计算从过去用户事件的历史上下文数据导出的用户行为测量来确定用户请求是否与常规用户行为不一致。接下来，系统允许用户提供与常规用户行为和/或当前语境数据相关联的信息。该系统基于当前的上下文数据进一步更新用户行为度量。

摘要： A performance-efficient activity-modeling system generates a group-activity model for a population group using information from an optimal subset of users of the population group. During operation, the system computes utility scores for a set of users based on a utility-scoring function, such that a respective utility score indicates a usefulness or penalty of collecting a corresponding user's contextual information. The system then selects, from the set of users, a subset of users with highest utility scores, and receives user information from each of the selected users. The system generates the group-activity model based on the user information received from the selected users.

摘要： Embodiments of the present disclosure provide a method and system for protecting privacy by generating artificial contextual data. The system collects real contextual data related to a user. The system then generates artificial contextual data, based on the collected real contextual data. The system also groups the generated contextual data into one or more groups. Each group of contextual data corresponds to a persona that can be presented as the user's persona. Subsequently, the system transmits the generated contextual data to an entity, thereby allowing the user to obscure the real contextual data related to the user.

摘要： A private stream aggregation (PSA) system contributes a user's data to a data aggregator without compromising the user's privacy. The system can begin by determining a private key for a local user in a set of users, wherein the sum of the private keys associated with the set of users and the data aggregator is equal to zero. The system also selects a set of data values associated with the local user. Then, the system encrypts individual data values in the set based in part on the private key to produce a set of encrypted data values, thereby allowing the data aggregator to decrypt an aggregate value across the set of users without decrypting individual data values associated with the set of users, and without interacting with the set of users while decrypting the aggregate value. The system also sends the set of encrypted data values to the data aggregator.
摘要翻译：私有流聚合（PSA）系统将用户的数据贡献给数据聚合器，而不会影响用户的隐私。系统可以通过在一组用户中确定本地用户的私钥来开始，其中与用户组和数据聚合器相关联的私钥的总和等于零。该系统还选择与本地用户相关联的一组数据值。然后，系统部分地基于私钥对集合中的各个数据值进行加密以产生一组加密的数据值，从而允许数据聚合器在该组用户之间解密聚合值，而不会解密与一组用户，并且在解密聚合值时不与该组用户交互。该系统还将一组加密的数据值发送到数据聚合器。

摘要： Embodiments of the present disclosure provide a method and system for implicitly authenticating a user to access controlled resources. The system first receives a request to access the controlled resource from a user. Then, the system determines whether the user request is inconsistent with regular user behavior by calculating a user behavior measure derived from historical contextual data of past user events. Next, responsive to the determined inconsistency of the user request, the system collects current contextual data of the user from one or more user devices without prompting the user to perform an explicit action for authentication. The system further updates the user behavior measure based on the collected current contextual data, and provides the updated user behavior measure to an access controller of the controlled resource to make an authentication decision based at least on the updated user behavior measure.

摘要： One embodiment provides a system that verifies a user's identity. The system generates a list including a plurality of items and formulates a substantially large set of security questions base on the plurality of items. The number of questions in the set is significantly larger than a subset of security questions presented to the user to reduce the likelihood of the same questions being asked repeatedly. During account creation, the system presents to the user the subset of questions, and receives and stores a response from the user. At least one question in the subset is selected based on user information that is automatically extracted from devices associated with the user. Subsequently, the system receives a request to reset the user's password and presents the subset of questions to the requester. The system determines whether the requester is the user by comparing the requester's response with the stored user response.
摘要翻译：一个实施例提供了一种验证用户身份的系统。系统生成包括多个项目的列表，并且基于多个项目来制定基本上大量的安全问题集合。该集合中的问题数量明显大于向用户呈现的安全问题的一个子集，以减少重复提出相同问题的可能性。在创建帐户期间，系统向用户呈现问题的子集，并接收并存储来自用户的响应。基于从与用户相关联的设备自动提取的用户信息来选择子集中的至少一个问题。随后，系统接收到重置用户密码的请求，并将问题的子集呈现给请求者。系统通过将请求者的响应与存储的用户响应进行比较来确定请求者是否是用户。
