WLF(Watch List Filtering)

As a fundamental principle, all customers who request real-name verification financial transactions are subject to sanction list filtering.

Major Functions
  • Managing the watch list data according to KoFIU's watch list filtering eligible target and arbitrary decision rule
  • Adjusting the matching rate of the search engine (Exact Matching and Fuzzy Matching) to the context and purpose
  • Checking for the matching customer if the person is identical from the person of sanction list data
  • Manage White List for the WLF passed customers
Characteristics
  • Search engine solution with Fuzzy Matching algorithm
