Abstract

A device may determine a price of a product based on first information concerning attributes of the product, and provide the price for display by a user device. The device may generate first hash values based on the first information, where a particular first hash value is associated with a particular attribute, and generate a first bit-string that includes the plurality of first hash values. The device may generate second hash values based on second information concerning the attributes of the product, where a particular second hash value is associated with the particular attribute. The device may generate a second bit-string that includes the second hash values, and determine a change to the particular attribute based on the first bit-string and the second bit-string. The device may determine a new price of the product based on the change, and provide the new price for display by the user device.

First claim

What is claimed is:

1. A method, comprising:
obtaining, by a device, first information,
wherein the first information includes user information which is used to determine a price of a product;

generating a first information bit-string based on the first information;
obtaining, by the device and after obtaining the first information, second information;
generating, by the device, a second information bit-string based on the second information;
determining, by the device, that the first information bit-string is different than the second information bit-string; and
causing, by the device, display information to indicate a change in the price of the product based on the first information bit-string being different than the second information bit-string.

2. The method of claim 1 , wherein the first information is information about a user and the second information is updated information about the user.

3. The method of claim 1 , wherein the first information is information about the product and the second information is updated information about the product.

4. The method of claim 1 , wherein obtaining the first information comprises:
receiving the product and the first information from a user device.

5. The method of claim 1 , further comprising:
causing the display information to display the price of the product after generating the first information bit-string.

6. The method of claim 1 , wherein obtaining the second information comprises one or more of:
obtaining the second information based on a triggering event, or
obtaining the second information after a threshold amount of time.

7. The method of claim 1 , wherein the first information bit-string includes one or more of:
a condition of the product,
an accident history of the product,
a mileage of the product,
a location of the product,
a user salary,
a user employment status,
a user address,
a user credit score,
a user credit history, or
a user bankruptcy status.

8. A device, comprising:
one or more memories; and
one or more processors, coupled to the one or more memories, to:
obtain first information,
wherein the first information includes user information which is used to determine a price of a product;

generate a first hash value based on the first information;
generate a first information bit-string based on the first hash value;
obtain, after obtaining the first information, second information;
generate a second hash value based on the second information;
generate a second information bit-string based on the second hash value;
determine that the first information bit-string is different than the second information bit-string; and
cause display information to indicate a change in the price of the product based on the first information bit-string being different than the second information bit-string.

9. The device of claim 8 , wherein the one or more processors are to:
receive a message; and
parse the message to identify the product and a user.

10. The device of claim 8 , wherein the first information bit-string includes the first hash value and a first unhashed value and the second information bit-string includes the second hash value and a second unhashed value.

11. The device of claim 8 , wherein the one or more processors, to obtain the first information, are to:
obtain data regarding the product from a data structure; and
parse the data to identify the first information.

12. The device of claim 8 , wherein the one or more processors are further to:
process the first information using a machine learning model to determine the price of the product.

13. The device of claim 8 , wherein the first information is information about a user and the second information is updated information about the user.

14. The device of claim 8 , wherein the one or more processors, to obtain the first information, are to:
receive, from a user device, a message indicating the product based on a prompt to identify a product of interest,
wherein the first information is based on one or more of the product or a user associated with the user device.

15. 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:
obtain first information,
wherein the first information includes user information which is used to determine a price of a product;

generate a first information bit-string based on the first information;
cause display information to display the price of the product;
obtain, after obtaining the first information, second information;
generate a second information bit-string based on the second information;
determine that the first information bit-string is different than the second information bit-string;
send updated display information to a device based on the first information bit-string being different than the second information bit-string; and
cause the updated display information to indicate a change in the price of the product.

16. The non-transitory computer-readable medium of claim 15 , wherein the first information bit-string includes a first hash value and a first unhashed value and the second information bit-string includes a second hash value and a second unhashed value.

17. The non-transitory computer-readable medium of claim 15 , wherein the one or more instructions, to obtain the first information, cause the one or more processors to:
send a signal to a server associated with a financial institution that provides financial services to a user to obtain the first information.

18. The non-transitory computer-readable medium of claim 15 , wherein the one or more instructions, to obtain the first information, cause the one or more processors to:
send a signal to a server associated with a merchant that sells the product to obtain the first information.

19. The non-transitory computer-readable medium of claim 15 , wherein the first information is one or more of user information or product information.

20. The non-transitory computer-readable medium of claim 15 , wherein the second information bit-string includes one or more of:
a condition of the product,
an accident history of the product,
a mileage of the product,
a location of the product,
a user salary,
a user employment status,
a user address,
a user credit score,
a user credit history, or
a user bankruptcy status.
