GM smart cards to be published at the end of the year call for encryption

Xinhua Beijing, May 27, according to the Hong Kong Wen Wei Po, the two sides of the common smart card will be published at the end of the year, security concerns.　　A computer security expert pointed out that although the smart card apart from two chips, from the different systems operating respectively, but the technology is still possible to read the wrong chip, resulting in the chip data leakage or deduction of the wrong money, the proposed card issuing agencies to encrypt transaction data. The senior lecturer of the Business Administration of the Hong Kong Institute of Vocational Education, who studies e-commerce security, said even if the smart card is handled by two different chips for renminbi and Hong Kong dollar accounts, there is still a technical possibility of reading the wrong data, "the Octopus and Shenzhen card readers have similar technical specifications and can technically read each other's chip data, If the reader is improperly tuned, it is possible to read the wrong chip and read the transaction data incorrectly.　　He pointed out that all smart card systems can be encrypted, as long as the encryption measures enough, I believe that can effectively avoid the problem of leakage of data.　　He added that the use of smart cards would naturally arouse public concern about the leakage of data, but he believed that if the common smart card technology was developed and the data encryption procedures were rigorous, it could be accompanied by the functions of the individual octopus and the development of security certification for buildings. Ko, manager of the Hong Kong Computer Security Incident Coordination Centre, said that the octopus chips contained only data on transaction records and account balances, and that the data would be stored in another database even if personal data were to be provided for personal octopus cards. But technically, the reader cannot be excluded from the possibility of reading the wrong chip data.
