A sensitive operation processing apparatus, comprising:
- a non-transitory storage medium accessible by a processor, the non-transitory storage medium including:
- instructions executable by the processor to receive a sequence obtaining request, the sequence obtaining request comprising a user account identifier, wherein the user account identifier is a combination of at least two of three types of characters comprising:
- digit, letter and symbol;
- instructions executable by the processor to convert the user account identifier into a preliminary feature sequence by causing the processor to:
- select a portion of characters of the user account identifier,
- multiply a predetermined number to the portion of characters selected to obtain a conversion code, and
- replace the portion of characters of the user account identifier with the conversion code, to the user account identifier to generate the preliminary feature sequence;
- instructions executable by the processor to determine the preliminary feature sequence exists in a preset conversion relationship between feature sequences and user account identifiers;
- instructions executable by the processor to modify, in response to the preliminary feature sequence existing in the preset conversion relationship, the preliminary feature sequence to generate a modified feature sequence;
- instructions executable by the processor to save a conversion relationship between the modified feature sequence and the user account identifier, wherein the modified feature sequence uniquely identifies a user account associated with the user account identifier;
- instructions executable by the processor to provide sensitive operation instruction information to a remote terminal, wherein the sensitive operation instruction information comprises at least the modified feature sequence;
- instructions executable by the processor to receive a sensitive operation request generated by the remote terminal, the sensitive operation request including the modified a first feature sequence and sensitive operation information;
- instructions executable by the processor to obtain the user account identifier associated with the modified feature sequence according to the preset conversion relationship between feature sequences and user account identifiers;
- instructions executable by the processor to execute a sensitive operation based on the sensitive operation information and the user account identifier corresponding to the modified feature sequence;
- and
- instructions executable by the processor to delete the conversion relationship between the modified feature sequence and the user account identifier in response to receipt, from the remote terminal, of an indication of a page applying to obtain a sequence being closed, or the sensitive operation request not being received within a specified time.
