a method is provided for efficiently transferring records related to places of interest between two communicating vehicles in a v2v system without initially having to transfer full text records . a determination is made as to whether information stored in a memory of the vehicle is redundant with the respect to the other vehicle . a query request is transmitted from a first vehicle to a second vehicle containing specifics as to what records the first vehicle is seeking . data satisfying the query request represented by global unique index numbers is hashed to determine the similarity between the data of the two communicating vehicles . the similarity is used to determine whether a full filtered set of global unique index numbers should be transferred to the second vehicle for determining which records are not duplicate records . thereafter , the second vehicle wirelessly transmits to the first vehicle the non - overlapping data that satisfies the query request .
