Abstract: Methods, software, and hardware are disclosed for providing verified real time price quotes in an over-the-counter financial market. Systems are described that can comprise methods, software, and/or hardware to provide verified real time price information for securities traded over-the-counter. Verification methods of the invention include identifying suspect source data, wherein the suspect source data includes information about the price of a security, verifying the suspect source data, and displaying to a user a verified price quote of a security traded in an over-the-counter market to a user. The verification methods of the invention include using hash functions and hash tables to process suspect source data, wherein the hashing allows for confidential processing while at the same time maintaining the ability to match a price quote to the source of the price quote.
