Abstract: A system and method provide for shared access to a database in a semi-trusted platform. In the method, for each of a set of users, provision is made for regenerating a respective user key, based on a respective predefined user input, such as a hashed password. One or more of the users is authorized to have access to an encrypted database. For each of these, the method includes encrypting a key for the encrypted database with the respective user's user key to generate an encrypted database key. During a user session, one of the authorized users is provided with access to the encrypted database by decrypting the database key from the encrypted database key with the respective user's user key, and decrypting the database, from the encrypted database, with the database key. The database key and each user's user key are not stored on the platform and are thus inaccessible to platform administrators and unauthorized users between user sessions.
Abstract translation: 系统和方法提供对半可信平台中的数据库的共享访问。 在该方法中，对于一组用户中的每一个，基于相应的预定义的用户输入（诸如散列密码）来提供用于再生相应的用户密钥。 一个或多个用户被授权访问加密的数据库。 对于这些中的每一个，该方法包括用相应用户的用户密钥加密加密的数据库的密钥以生成加密的数据库密钥。 在用户会话期间，通过用加密数据库密钥用相应用户的用户密钥解密数据库密钥，并从加密的数据库中用数据库密钥对数据库进行解密，为授权用户之一提供对加密数据库的访问。 数据库密钥和每个用户的用户密钥不会存储在平台上，因此在用户会话之间，平台管理员和未授权用户无法访问数据库密钥。

Abstract: A system and method to establish a no-login authenticated and contextualized two-ways data flow between a medicine user and the pharmaceutical manufacturer. Near Field Communication (NFC) technology, enabling short-range communication between two compatible devices is utilized via a writeable NFC tag carried by a medication package. The writeable NFC tag includes medication information, anti-counterfeiting information, as well as data about the patient and the prescription. The NFC tag may be read by a user device associated with the patient, enabling the user device to merge this data with the patient's feedback, send this rich flow in a secure way to the manufacturer, who in turn is now able to provide rich contextual guidance to the patient.

Abstract: A method for authentication of user reviews includes providing a user certificate to a user's mobile device. A transaction log is received from the mobile device. The transaction log includes an encrypted tag identifier which has been transmitted to the mobile device from a review tag at a location where a service is provided by a service provider when the review tag has verified the validity of the user certificate. The encrypted tag identifier is decrypted to identify the service provider. The user is prompted to submit a review of the service provided by the service provider.

Abstract: A method for extracting entities from a text document includes, for at least a section of a text document, providing a first set of entities extracted from the at least a section, clustering at least a subset of the extracted entities in the first set into clusters, based on locations of the entities in the document. Complete ones of the clusters of entities are identified. Patterns for extracting new entities are learned based on the complete clusters. New entities are extracted from incomplete clusters based on the learned patterns.

Abstract: Disclosed is a relational database fingerprinting system and method to identify a user of the relational database, the fingerprint provided by an originator of the relational database. According to an exemplary method, a fingerprint bit string is generated including a data user identification code and a secret key unknown to the user, and the fingerprint bit string is embedded in a plurality of pseudorandomly selected values based on a pseudorandom function seeded with primary keys associated with the relational database.
