A computer-implemented method includes: obtaining, by a computing device, an original Personal Account Number (PAN) to be transformed; transforming, by the computing device, the original PAN to form a transformed PAN; performing, by the computing device, a verification on the transformed PAN; determining, by the computing device, whether the transformed PAN passes verification; and storing or outputting, by the computing device, the transformed PAN based on determining that the transformed PAN does not pass verification, wherein the original PAN is later recovered from the transformed PAN to process a transaction.

A method and system for converting voice data to text data between users is provided. The method includes receiving voice data from at least one user and determining phoneme data items corresponding to the voice data. Conversion candidate string representations of the phoneme data items are identified by referencing a conversion dictionary defining the conversion candidate string representations for each phoneme data item. The plurality of conversion candidate string representations are scored and a specified conversion candidate string representation is selected as text data based on the scores. The text data is transmitted to a terminal device accessed by the at least one user.
