2D-BARCODE GENERATING AND MOBILE IDENTIFICATION SYSTEM IN UBIQUITOUS ENVIRONMENT

摘要

The present invention, if necessary, is that to allow the identification by the mobile terminal to apply the two-dimensional barcode (2D-barcode) and the electronic signature scheme recorded in the large capacity data, the mobile identification of the terminal holder of the mobile terminal to form 2-D bar code is to be output, whereby the recorded data on the basis of an asymmetric encryption by a secret key (private key) at the same time as applying the digital signature scheme, the mobile communication terminal and the two-dimensional bar code enters the read that to the terminal in real time so as to enable the application of an electronic signature to confirm validity multi multiple or variable signature key (key) to ensure that each of through the mobile communication network and the Internet connection to the service server.; Through the present invention, it was able to increase the security in the identification by the mobile terminal, whereby the effect can be obtained to enable the relevant authentication and e-commerce services.
