摘要： Systems and methods that allow the formation and distribution of session keys amongst a dynamic group of users communicating over an unreliable, or lossy, network. The systems and methods according to this invention allow an intermediate session key contained in an intermediate key distribution broadcast to be determined by receiving a preceding key distribution broadcast that precedes the intermediate key distribution broadcast, the preceding key distribution broadcast including a first portion of the intermediate session key; receiving a subsequent key distribution broadcast that follows the intermediate key distribution broadcast, the subsequent key distribution broadcast including a second portion of the intermediate session key that is distinct from the first portion; and combining at least the first portion of the intermediate session key contained within the preceding key distribution broadcast and the second portion of the intermediate session key contained within the subsequent key distribution broadcast to obtain the intermediate session key.

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.

摘要： A selectively encrypted data unit includes an encrypted version of sensitive information (capable of being decrypted to reveal the sensitive information), a plurality of auxiliary values, and an attribute vector associated with the encrypted version of the sensitive information. The selectively encrypted data unit and a unique capability key are accessed. The unique capability key is associated with a key descriptor and is responsive to one or more cryptosystem parameters, one or more random numbers and one or more shares of a master secret. Next the technology determines whether the attribute vector is filtered or enabled by the key descriptor. If so, a protection key is acquired that is responsive to the one or more cryptosystem parameters, the plurality of auxiliary values, the key descriptor and the unique capability key. Once acquired, the protection key is used to decrypt the encrypted version to generate the sensitive information which is presented.

摘要： One embodiment of the present invention provides a system that detects inferences from documents. During operation, the system receives one or more documents and extracts a first set of knowledge relevant to the documents. The system further formulates one or more queries to one or more reference corpora based on the first set of knowledge. The system then extracts a second set of knowledge from results received in response to the queries. Additionally, the system produces a mapping relationship between at least one document and a piece of the second set of knowledge which is not within the first set of knowledge, the mapping relationship indicating an inference from the documents.

摘要： One embodiment provides a system for facilitating sanitizing a modified version of a document relative to one or more sensitive topics. During operation, the system determines a privacy risk for a term in the modified version relative to the sensitive topics, wherein the privacy risk measures the extent to which the sensitive topic(s) can be inferred based on the term. Next, the system determines an information utility and privacy loss or gain for the modified version, where the information utility reflects the extent to which the modified version has changed and the privacy loss or gain reflects the extent to which the modified version is reduced in sensitivity.

摘要： One embodiment provides a system that detects sensitive passages. During operation, the system receives a document and disassembles the document into a plurality of passages. For a respective passage, the system performs a search through a non-sensitive-passage database to determine whether the passage is a known non-sensitive passage. If so, the system marks the passage as non-sensitive, and if not, the system determines whether the passage triggers a cut-and-paste attack detection. If so, the system forwards the passage to an administrator and allows the administrator to determine whether the passage is non-sensitive and, further, to add the passage to the non-sensitive-passage database responsive to the administrator determining the passage to be non-sensitive.
