Accuracy and security of data transfer to an online user account

1. A computer-implemented method, comprising:

receiving account information input by a user for data transfer;

determining identity information associated with the received account information;

determining one or more pieces of account information associated with the determined identity information, wherein the one or more pieces of account information are determined based on a ratio of a number of elements of the account information associated with the determined identity information being the same as a number of elements of the received account information to a number of elements of the account information associated with the determined identity information not being the same as a number of elements of the received account information, and the one or more pieces of account information include the received account information;

providing the one or more pieces of account information to the user; and

in response to receiving a user confirmation of the one or more pieces of account information, performing the data transfer based on the user confirmation.

2. The method of claim 1 , wherein the one or more pieces of account information include more than one piece of account information, the user confirmation comprising a user selection of one of the more than one piece of account information.

3. The method of claim 1 , wherein determining one or more pieces of account information associated with the determined identity information includes at least one of:

querying a relationship list for one or more pieces of account information associated with the determined identity information, wherein the relationship list stores a plurality of pieces of identity information, and for each piece of identity information the relationship list stores one or more pieces of account information that satisfy a predetermined threshold associated with the ratio; and

querying an account information database for one or more pieces of account information associated with the determined identity information.

4. The method of claim 3 , wherein the one or more pieces of account information associated with the determined identity information are determined from querying the account information database, the method further comprising storing the determined one or more pieces of account information associated with the determined identity information in the relationship list.

5. The method of claim 3 , further comprising:

receiving a user feedback for the data transfer; and

in response to receiving the user feedback, storing the determined one or more pieces of account information associated with the determined identity information in the relationship list.

6. The method of claim 1 , wherein providing the one or more pieces of account information to the user includes providing the one or more pieces of account information with the received account information to the user.

7. A non-transitory, computer-readable medium storing one or more instructions executable by a computer system to perform operations comprising:

receiving account information input by a user for data transfer;

determining identity information associated with the received account information;

determining one or more pieces of account information associated with the determined identity information, wherein the one or more pieces of account information are determined based on a ratio of a number of elements of the account information associated with the determined identity information being the same as a number of elements of the received account information to a number of elements of the account information associated with the determined identity information not being the same as a number of elements of the received account information, and the one or more pieces of account information include the received account information;

providing the one or more pieces of account information to the user; and

in response to receiving a user confirmation of the one or more pieces of account information, performing the data transfer based on the user confirmation.

8. The non-transitory, computer-readable medium of claim 7 , wherein the one or more pieces of account information include more than one piece of account information, the user confirmation comprising a user selection of one of the more than one piece of account information.

9. The non-transitory, computer-readable medium of claim 7 , wherein determining one or more pieces of account information associated with the determined identity information includes at least one of:

querying a relationship list for one or more pieces of account information associated with the determined identity information, wherein the relationship list stores a plurality of pieces of identity information, and for each piece of identity information the relationship list stores one or more pieces of account information that satisfy a predetermined threshold associated with the ratio; and

querying an account information database for one or more pieces of account information associated with the determined identity information.

10. The non-transitory, computer-readable medium of claim 9 , wherein the one or more pieces of account information associated with the determined identity information are determined from querying the account information database, the operations further comprising storing the determined one or more pieces of account information associated with the determined identity information in the relationship list.

11. The non-transitory, computer-readable medium of claim 9 , the operations further comprising:

receiving a user feedback for the data transfer; and

in response to receiving the user feedback, storing the determined one or more pieces of account information associated with the determined identity information in the relationship list.

12. The non-transitory, computer-readable medium of claim 7 , wherein providing the one or more pieces of account information to the user includes providing the one or more pieces of account information with the received account information to the user.

13. A computer-implemented system, comprising:

one or more computers; and

one or more computer memory devices interoperably coupled with the one or more computers and having tangible, non-transitory, machine-readable media storing instructions that, when executed by the one or more computers, perform operations comprising:

receiving account information input by a user for data transfer;

determining identity information associated with the received account information;

determining one or more pieces of account information associated with the determined identity information, wherein the one or more pieces of account information are determined based on a ratio of a number of elements of the account information associated with the determined identity information being the same as a number of elements of the received account information to a number of elements of the account information associated with the determined identity information not being the same as a number of elements of the received account information, and the one or more pieces of account information include the received account information;

providing the one or more pieces of account information to the user; and

in response to receiving a user confirmation of the one or more pieces of account information, performing the data transfer based on the user confirmation.

14. The system of claim 13 , wherein the one or more pieces of account information include more than one piece of account information, the user confirmation comprising a user selection of one of the more than one piece of account information.

15. The system of claim 13 , wherein determining one or more pieces of account information associated with the determined identity information includes at least one of:

querying a relationship list for one or more pieces of account information associated with the determined identity information, wherein the relationship list stores a plurality of pieces of identity information, and for each piece of identity information the relationship list stores one or more pieces of account information that satisfy a predetermined threshold associated with the ratio; and

querying an account information database for one or more pieces of account information associated with the determined identity information.

16. The system of claim 15 , wherein the one or more pieces of account information associated with the determined identity information are determined from querying the account information database, the operations further comprising storing the determined one or more pieces of account information associated with the determined identity information in the relationship list.
