Abstract: Risk scores are generated by systems that use features or inputs from the current transactions, some summary statistics like velocity and some statistics calculated in batch mode which traverse hierarchical classification levels of entities, including classified attribute levels of known transactions, to identify neighborhoods of related entities and related transactions. Corresponding records of transaction information are extracted from or are otherwise generated from neighborhoods of the related transactions associated with the defined neighborhoods of entities/transactions.

Abstract: The disclosed embodiments concern methods, apparatus, systems and computer program products for determining and displaying pedigrees based on IBD data. Some implementations use a probabilistic relationship model to obtain various likelihoods of various potential relationships based on pairwise IBD data and pairwise age data. Some implementations build large pedigrees by combining smaller pedigrees. Some implementations display pedigree graphs with various features that are informative and easy to understand.

Abstract: Different fraud risk models can be developed and applied for a consortium of e-commerce merchants. With this multi-phase modeling strategy, a consortium member can get its optimal model performance at different data phases from an early phase where the consortium member does not have any historical data, to a more mature phase where the consortium member has a short time period of matured data, to a fully mature phase where the consortium member has a long-time period of matured data. On the other hand, the matured consortium data is not affected by the immature data from new members. Thus, the model performance for long-time existing members is not affected by new members at immature phases.
