Abstract: Relationships between data in database tables are obfuscated. An input data set is divided into two database tables with corresponding rows. A key field if created in a second one of the tables, and for each row, the field is populated with a value generated with a one-way function, using a unique value associated with the corresponding row of the first one of the tables as an input. The two tables are stored in a data store, so that the data in corresponding rows may be associated only with access to the one way function, and the unique value associated with a row of the first table.

Abstract: A method and system are disclosed for identifying in real time duplicate financial documents processed by a financial institution or check clearinghouse. A collection of hash values representative of previously processed financial documents are maintained in a memory, such as a GPU memory. When a new financial document enters the financial institution or check clearinghouse for processing, one or more features of the financial document are captured. A hash value is generated from the one or more features of the financial document. A search is performed in the collection of hash values for a matching hash value. If a match is found, a potential fraudulent event or operational error may be indicated. If a match is not found, the hash value representative of the new financial document is added to the collection of hash values.

Abstract: A distributed replicated database system having a plurality of federated database systems and methods of updating and reading database records from the distributed replicated database system are disclosed. Each federated database system contains a complete copy of a database. Moreover, each federated database system comprises at least one server divided into at least one logical partition. A logical partition contains records of the database and all logical partitions in a federated database system cumulatively stores all records in the database. A data structure is maintained which indicates whether the records in a given logical partition are up-to-date. When an update or insert request is received, the data structure is modified to indicate that all logical partitions storing a copy of the record to be updated, or partitions into which the new record is to be inserted, are not up-to-date.

Abstract: Relationships between data in database tables are obfuscated. An input data set is divided into two database tables with corresponding rows. A key field if created in a second one of the tables, and for each row, the field is populated with a valve generated with a one-way function, using a unique valve associated with the corresponding row of the first one of the tables as an input. The two tables are stored in a data store, so that the data in corresponding rows may be associated only with access to the one way function, and the unique valve associated with a row of the first table.
