Abstract
A first device generates a first signature by using complete transaction data received from a second device, a first algorithm and a first key, modifies at least one character from the complete transaction data and gets partial transaction data, and sends to the second device the partial transaction data. The second device requests a user to modify the partial transaction data by providing at least one character, as complementary data to the partial transaction data, gets, as request response from a user, at least one character to modify the partial transaction data, a corresponding result being proposed modified transaction data, generates a second signature by using the proposed modified transaction data, the first algorithm and the first key, and sends to the first device the second signature. Only if the second signature does match the first signature, then the first device authorizes to carry out a corresponding transaction.
