obtaining, by a server device, first information concerning user information regarding a user interested in a product, wherein the user information includes information used to determine a price of the product;
generating, by the server device, a first hash value based on the first information;
generating a first bit-string that includes the first hash value;
obtaining, by the server device and after obtaining the first information, second information concerning the user information;
generating, by the server device, a second hash value based on the second information;
generating a second bit-string that includes the second hash value;
determining, by the server device, a change in the user information based on a comparison of the first bit string and the second bit string; and
