Abstract: 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.
Abstract translation: 本发明的一个实施例提供了一种允许文档所有者从文档中修改内容并允许编辑文档的接收者挑战编辑的适当性的系统。 在操作期间，系统允许文档所有者从文档中的位置i修改字符串Mi。 在这样做时，系统基于字符串Mi产生承诺Ci = C（Mi，Ri）和用作随机性的字符串Ri，并将Ci传送给接收者。 当接收方挑战编辑时，系统从收件人接收主题字符串T，并产生字符串RT。 系统然后将RT传送给接收者，从而允许接收者基于字符串T和RT产生承诺CT = C（T，RT），并将CT与Ci进行比较。 将承诺CT与Ci进行比较，允许收件人对字符串相等性进行测试。

Abstract: A selectively encrypted data unit is generated from an unencrypted data unit. This is accomplished by accessing a list of attributes related to the unencrypted data unit that identify classifications of sensitive information within the unencrypted data unit. In addition, a protection key that is responsive to a random number is selected and auxiliary values computed from the attributes of the sensitive information and the random number are produced. The sensitive information is encrypted with the protection key to create an encrypted version of the sensitive information. The encrypted version is associated with the auxiliary values and linked to an attribute vector that classifies the sensitive information in the encrypted version. Data from the unencrypted data unit and the encrypted version of the sensitive information is stored as the selectively encrypted data unit.

Abstract: 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.

Abstract: 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.

Abstract: 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.
