Abstract
Example implementations include a method for using tokens between two entities including a client device and a server, by generating, by a first one-way function of the client device, a first intermediate value from a transaction count corresponding to a number of transactions involving an original data, the first intermediate value being unique to a first verification transaction at a server, generating, by a second one-way function of the client device, a second intermediate value from the first intermediate value, the second intermediate value being unique to a second verification transaction at the server, sending, by the client device, a first token based on the first intermediate value to the server to execute the first verification transaction, and sending, by the client device, a second token based on the second intermediate value to the server to execute the second verification transaction.
