Abstract: Described are computer-based methods and apparatuses, including computer program products, for parsing, flagging, and/or reconstructing data on a network. Data packets associated with user requests are distributed among a plurality of data centers for processing. The data packets are captured at the data centers for fraud detection. The captured data packets are preprocessed at the data center. The preprocessing includes disregarding data packets that are not applicable to fraud detection. The preprocessing includes indicating if data packets are applicable to fraud detection. The indicating of the applicable data packets includes parsing the data packets using particular rules optimized for fraud detection. The data packets are processed at each data center to reconstruct part of the data associated with a user. The processing of the data packets includes reconstructing the data packets based on customer information from network information and/or cookie information.
