Abstract: A system performs masking of data stored in a database. The system receives change logs from a source database and masks the change logs to generate masked change logs. The system stores the masked change logs in a pre-buffer. If the system determines that the set of masked change logs stored in the pre-buffer corresponds to a complete transaction, the system determines whether any conflicts exist between masked change logs stored in the pre-buffer and masked change logs stored in a main buffer. If the system identifies conflicts, the system applies the masked change logs stored in the main buffer to a masked replica database. This causes the system to move masked change logs corresponding to a complete transaction from the pre-buffer to the main buffer.

Abstract: A method for secure data transformation and lookup is executed by a computer system. A data value to create an encrypted value is encrypted by the computer system. A hash value based on the encrypted value is generated by the computer system. A modulo operation is performed by the computer system on the hash value to create a modulo value. A transformed value from a lookup table is retrieved by the computer system by using the modulo value as an index for the look up table. The transformed value is provided by the computer system.

Abstract: Described are methods and apparatus, including computer program products for masking data. The inventions involves receiving a mapping scheme with a number of segments and a different cryptographic algorithm for each segment and then receiving a target value to be masked. The target value is then split into a number of segments based on the number of segments of the mapping scheme and the cryptographic algorithm is applied for each segment in the mapping scheme to each segment of the target value to generate an encrypted segment for each segment in the target value. Then, the encrypted segments are concatenated to create a masked value.

Abstract: Described are methods, systems, and apparatus, including computer program products for securing data of a production server. The invention, in one implementation, includes reading a data value on the production server, obfuscating the data value in the memory of the server to create a masked value, transmitting the masked value to a non-production server, and storing the masked value on the non-production server.
