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： One embodiment provides a computer system for detecting associations between a reviewer and an entity under review. During operation, the system estimates a relationship strength between the reviewer and the entity under review, and determines whether the relationship strength between the reviewer and the entity under review exceeds a predetermined threshold.

摘要： A targeted advertising system performs context-based association mining using a publicly available corpus to identify a product or brand name that, under a given context, is associated with a product or brand being marketed. The system analyzes documents within the publicly available corpus that are associated with the given context, and identifies products or brand names that have a high association to the product or brand being marketed. The system can also analyze the publicly available corpus to determine contextual information which is correlated to two or more products or brand names. This contextual information includes a set of terms that facilitates filtering the publicly available corpus into an optimal set of documents that has a high association to a desired market category or demographic.

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： One embodiment of the present invention provides a system for resetting a user's forgotten password. During operation, the system receives a user's request for resetting the user's forgotten password and derives one or more challenges from the user's forgotten password. The system then presents the derived challenges to the user and receives a response from the user to the challenges. The system further compares the user's response to the one or more challenges with the user's forgotten password, thereby facilitating password resetting.

摘要： A system for displaying a set of selectable CAPTCHAs produces a first set of CAPTCHAs whose images are based at least partially on an alphanumeric sequence, where a respective CAPTCHA in the first set is associated with a CAPTCHA property. The system also produces a second set of CAPTCHAs whose images are based at least partially on an alphanumeric sequence, where a respective CAPTCHA in the second set is not associated with a CAPTCHA property. Next, the system displays the first and second sets of CAPTCHAs. Finally, the system makes respective CAPTCHAs in the first and second sets of CAPTCHAs selectable, thereby allowing a user to pass a CAPTCHA challenge by distinguishing the first set of CAPTCHAs from the second set of CAPTCHAs without typing the words associated with the images.

摘要： One embodiment of the present invention provides a system that facilitates filtering outbound content via inference detection. During operation, the system identifies content sent to a first address and extracts keywords from the identified content. The system then issues queries based on these keywords and extracts expected-content keywords from the hits returned in response to the queries. The system then searches the outbound content for occurrences of the expected-content keywords and produces a result which allows a user to determine whether the outbound content is proper. In a further embodiment, the system extracts keywords from a piece of outbound content, and issues queries based on these keywords. The system then extracts keywords from the hits, and present at least one keyword to a user, thereby allowing the user to determine whether the outbound content is proper.

摘要： One embodiment of the present invention provides a system for automatically authenticating a user. During operation, the system receives a user's request for authentication. The system then extracts information associated with the user from user-specific information stored in an enterprise computer. The extracted user information does not explicitly relate to a password. The system further generates one or more challenges based on the extracted user information, and receives the user's response to the challenges. Subsequently, the system compares the user's response to the extracted user information, and authenticates the user.
