System and method for detecting and alerting risks of inputting incorrect account information in refill transactions

1. A method, implemented by a processor device, for detecting a risk in a refill transaction, comprising:

receiving, from a user, a request for refilling an account, the request including account information associated with the account;

acquiring a contact information set corresponding to the user;

determining, by the processor device, whether the contact information set includes the account information by searching in the contact information set for information matching the account information;

providing, responsive to a determination that the contact information set does not include the account information, a risk alert to the user, the risk alert including a notification to the user for checking whether an inputting mistake occurs;

searching in the contact information set for information partially matching the account information;

displaying, responsive to locating a partially matched contact information having a similarity higher than or equal to a preset similarity threshold, the partially matched contact information to the user;

comparing the account information with the partially matched contact information and determining a matched portion and a non-matched portion in the partially matched contact information, wherein the non-matched portion corresponds to a portion of the partially matched contact information that is different from a corresponding portion of the account information and wherein the matched portion corresponds to a portion of the partially matched contact information that is the same as a corresponding portion of the account information; and

displaying the matched portion and the non-matched portion of the partially matched contact information in different manners.

2. The method of claim 1 , wherein the contact information set includes contact information corresponding to the user obtained from an electronic address book.
