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 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
causing, by the server device, display information indicating a change in the price of the product by a user device based on the change in the user information.

2. The method of claim 1 , where obtaining the first information concerning the user information comprises:
sending a signal to a server associated with a financial institution that provides financial services to the user.

3. The method of claim 1 , wherein the first bit-string includes the first hash value and a first unhashed value and the second bit-string includes the second hash value and a second unhashed value.

4. The method of claim 1 , further comprising:
receiving a message; and
parsing the message to identify the product and the user.

5. The method of claim 1 , wherein the user information includes one or more of:
financial-related information of the user,
salary information of the user,
an employment status of the user,
a bankruptcy status of the user,
a credit score of the user, or
credit history information of the user.

6. The method of claim 1 , wherein generating the first hash value based on the first information comprises:
generating the first hash value using:
a Jenkins hash function, a Pearson hashing function, a Bernstein hashing function, a Fowler-Noll-Vo hashing function, or
a Zobrist hashing function.

7. The method of claim 1 , wherein the first bit-string that includes the first hashed value based on user credit history information.

8. 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 user information based on a comparison of the first bit-string and the second bit-string; and
provide a change in the price of the product to a user device based on the change in the user information.

9. The device of claim 8 , wherein the one or more processors, when obtaining the second information, are configured to:
obtain the second information based on a triggering event.

10. The device of claim 7 , wherein the one or more processors, when obtaining the first information concerning the user information, are configured to:
send a signal to a server associated with a financial institution that provides financial services to the user.

11. The device of claim 8 , wherein the one or more processors are further configured to:
obtain a message to identify the product and identify the user.

12. The device of claim 8 , wherein the user information includes one or more of:
salary information of the user,
an employment status of the user,
a bankruptcy status of the user,
a credit score of the user, or
credit history information of the user.

13. The device of claim 8 , wherein the one or more processors, when obtaining the second information concerning the user information, are configured to:
obtain updated user information associated with a marriage status of the user.

14. The device of claim 8 , wherein the first bit-string that includes the first hashed value based on user credit history information.

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:
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 bit-string based on the first information;
obtain, after obtaining the first information, second information concerning the user information;
generate a second bit-string based on the second information;
determine a change in the user information based on a comparison of the first bit-string and the second bit-string; and
provide a change in the price of the product to a user device based on the change in the user information.

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

17. The non-transitory computer-readable medium of claim 15 , wherein the one or more instructions, that cause the one or more processors to determine the product of interest to the user, cause the one or more processors to:
parse a message to identify the product and identify the user.

18. The non-transitory computer-readable medium of claim 15 , wherein the one or more instructions, that cause the one or more processors to determine the product of interest to the user, cause the one or more processors to:
receive a message identifying the product and the user.

19. The non-transitory computer-readable medium of claim 15 , wherein the one or more instructions, cause the one or more processors to:
purchase the product based on the change in price of product.

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