Determining a change to product information or user information via hashing

A device, comprising:

• one or more memories;
• and
• one or more processors, communicatively coupled to the one or more memories, configured to:
• obtain first information concerning user information regarding a user interested in a product,
• wherein the user information includes information that is relevant to determining a price of the product;
• generate a first bit string that includes a first hash value based on the first information;
• obtain, after obtaining the first information, second information concerning the user information;
• generate a second bit-string that includes a second hash value based on the second information;
• determine a change in the price of the product based on a comparison of the first bit-string and the second bit-string;
• and
• provide the change in the price of the product to a user device.

A non-transitory computer-readable medium storing instructions, the instructions comprising:

• one or more instructions that, when executed by one or more processors, cause the one or more processors to:
• determine a product of interest to a user;
• obtain first information concerning user information regarding the user,
• wherein the user information includes information used to determine a price of the product;
• generate a first hash value based on the first information;
• obtain, after obtaining the first information, second information concerning the user information;
• generate a second hash value based on the second information;
• determine a change in the price of the product based on a comparison of the first hash value and the second hash value;
• and
• provide the change in the price of the product to a user device.
