Abstract: A source application reads a body of data in data block sized units and calculates a checksum value for each data block before sending the data block, the calculated checksum value and the identifier. Upon receipt, a destination application independently calculates a checksum value for each received data block and compares the two checksums. Non-matching checksums indicate a network-induced error in the data block. Identifiers for the erroneous data blocks are transmitted to the source application after all of the data blocks have been initially transmitted. The source application thereafter resends only those data blocks identified. The destination application repeats the process of comparing checksums and transmitting identifiers to the source application until all of the data blocks of the body of data have been correctly received, and then uses the data blocks to recreate the body of data.

Abstract: A method, system and computer program product for confirming the validity of data returned from a data store. A data store contains a primary data set encrypted using a first encryption and a secondary data set using a second encryption. The secondary data set is a subset of the primary data set. A client issues a substantive query against the data store to retrieve a primary data result belonging to the primary data set. A query interface issues at least one validating query against the data store. Each validating query returns a secondary data result belonging to the secondary data set. The query interface receives the secondary data result and provides a data invalid notification if data satisfying the substantive query included in an unencrypted form of the secondary data result is not contained in an unencrypted form of the primary data result.

Abstract: The present invention provides for a system and method for assuring integrity of deduplicated data objects stored within a storage system. A data object is copied to secondary storage media, and a digital signature such as a checksum is generated of the data object. Then, deduplication is performed upon the data object and the data object is split into chunks. The chunks are combined when the data object is subsequently accessed, and a signature is generated for the reassembled data object. The reassembled data object is provided if the newly generated signature is identical to the originally generated signature, and otherwise a backup copy of the data object is provided from secondary storage media.

Abstract: A method, system, and computer instructions for using MD4 checksum to link transactions across machines. Transaction information is received, wherein transaction information comprises a checksum and topology information, and wherein the checksum serves as a unique identifier of the current transaction. A first data structure is populated with the checksum and attribute information for the current transaction. A second data structure is then populated with the checksum and topology information for the current transaction, wherein populating the second table preserves a root/parent/current transaction relationship. Preserving the root/parent/current transaction relationship allows for automatically linking a transaction to its related transactions when the transaction is uploaded from a client to a transaction database.

Abstract: A request for a software service utilizes a service intermediary. The service intermediary 1) checks the request to confirm that it conforms to XML well-formedness, and 2) validates the schema of the request. If the request passes both tests, then flags are appended to the request, which is sent to a service provider. The flag indicates to the service provider that the request has already been checked and validated, such that the service provider only needs to provide the requested service, without redundantly checking and validating the request.
