Kind Code:
A1
Abstract:
The present invention provides a ciphertext-based identity verification method, comprising: a data processing server pushing one or more first usage limit keys and one or more second usage limit keys to a mobile terminal of a user periodically or based on a request; when the user initiates a security information interaction process via the mobile terminal, a security application residing on the mobile terminal using one of the one or more first usage limit keys to generate an application ciphertext, and using one of the one or more second usage limit keys to generate a user ciphertext, and then transmitting the application ciphertext and the user ciphertext to a security information interaction terminal; and after receiving the application ciphertext and the user ciphertext, the security information interaction terminal constructing a security information interaction request and transmitting the security information interaction request to the data processing server to perform a subsequent security information interaction process.
