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.

摘要： One embodiment of the present invention provides a system which allows a document owner to redact content from a document and allows a recipient of the redacted document to challenge the appropriateness of the redaction. During operation, the system allows the document owner to redact a string Mi from location i in the document. In doing so, the system produces a commitment Ci=C(Mi, Ri) based on string Mi and a string Ri used as randomness and communicates Ci to the recipient. When the recipient challenges the redaction, the system receives a topic string T from the recipient, and produces a string RT. The system then communicates RT to the recipient, thereby allowing the recipient to produce a commitment CT=C(T, RT) based on strings T and RT, and compare CT with Ci. Comparing commitment CT with Ci allows the recipient to test redactions for string equality.

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： A system is provided to detect email spam. During operation, the system receives an email, extracts a set of keywords from the email body, and constructs a first search query based a keyword extracted from the email body. The system further constructs a second search query based on the keyword in the first query and one additional word which pertains to a known spam word or to the subject of the email. Next, the system receives a first number of hits and a second number of hits in response to the first and second search queries, respectively. The system then determines whether the email is spam based on the first number and the second number. The system can also perform Website filtering using inference detection which is based on search results received in response to search queries formulated with keywords extracted from Websites.

摘要： Techniques for protecting non-public information in a mobile environment are provided. A request for non-public information about users in a mobile environment is received. Privacy policies, non-public and optional public information about the users affected by the request are determined. An optional privacy impact indicator is determined based on how satisfying the request increases the current public information about the users. Crowds of users having similar attribute name/values are optionally determined. User and optional requestor privacy policies which associate threshold release criteria such minimum crowd size, minimum consideration with the non-public information are determined. A privacy agreement is reached for the disclosure of the requested non-public information based on the compatibility of the requester and user privacy policies. Privacy protecting transformations are optionally determined and applied to create crowds or groups associated with the requested attribute.

摘要： One embodiment of the present invention provides a system that performs inference detection based on Internet advertisements. In doing so, this system first receives a set of topic words, performs a search query on each topic word using a search engine, and gathers a set of Uniform Resource Locators (URLs) associated with sponsored advertisement from the search results corresponding to each search query. Then, the system determines a correlation between two topic words based on their corresponding URLs associated with sponsored advertisement, and produces a result which indicates groups of correlated topic words.

摘要： A server system maintains records and their associated attributes in a secure database. A plurality of queries generated by encrypting indices identifying a records and their associated attributes, by homomorphic encryption is received from a client system. A secret key is generated at a certain query count and is divided into randomly generated key shares. A key share sequence is homomorphically encrypted. A table is formed by encrypting the indices, secret key and attributes. Query responses, which each comprise the attributes for each of the records of the table of entries are provided. The key shares are decrypted sufficient to recover the secret key subject to a non-inference enabling query.

摘要： A capability key is generated that provides access to sensitive information within a selectively encrypted data unit created from an unencrypted data unit. A user specifies access rights as a monotone boolean relationship between a selection of a list of attributes related to the unencrypted data unit. This relationship is used to compute a key descriptor. Next one or more shares of a master secret is generated responsive to the monotone boolean relationship and a random number. Next a unique capability key is computed from one or more cryptosystem parameters, the one or more shares and the random number. The unique capability key and the key descriptor together enable decryption of sensitive information within a selectively encrypted data unit created from an unencrypted data unit. Finally, the unique capability key and the key descriptor are provided to allow decryption of sensitive information within the selectively encrypted data unit.
