Title:
DATA TRANSMISSION METHOD AND SYSTEM
Document Type and Number:
WIPO Patent Application WO/2019/165572
Kind Code:
A1
Abstract:
The present invention relates to the field of data processing, and particularly relates to a data transmission method and system. In the present invention, the method comprises: a mobile terminal acquiring a public key from a POS terminal; the mobile terminal encrypting a PIN code according to the public key to obtain a PIN code ciphertext; the mobile terminal sending the PIN code ciphertext to the POS terminal, so that the POS terminal acquires account information corresponding to the PIN code ciphertext according to a private key corresponding to the public key; and the mobile terminal forwarding a ciphertext of the account information from the POS terminal to a payment terminal, so that the payment terminal verifies the validity of the account information according to the ciphertext of the account information. The transmission security of a PIN code is improved while the costs are reduced.
