Claim 6:
7. The method as claimed in claim 1, wherein before step s1), said method further comprises building the security channel, by the upper computer, with the personal device;
building the security channel comprises the following steps:
a1) sending, by the upper computer, a handshake request including a handshake random number to the personal device; and
a2) encrypting, by the personal device, the handshake random number in the handshake request by using the pre-appointed initial key to obtain a data transmission key; and returning a handshake response to the upper computer;
sending, by the upper computer, the personalized data package to the personal device via the security channel specifically is that encrypting, by the upper computer, the personalized data package by using the data transmission key of the upper computer, and sending the encrypted personalized data package to the personal device;
sending, by the upper computer, the verification request to the personal device via the security channel specifically is that encrypting, by the upper computer, the verification request by using the data transmission key of the upper computer, and sending the encrypted verification request to the personal device;
before parsing, by the personal device, the personalized data package to obtain the second personalized information, the method further comprises decrypting, by the personal device, the encrypted personalized data by using the data transmission key of the personal device;
before reading, by the personal device, the time window and the dynamic verification code from the financial IC card, the method further comprises decrypting, by the personal device, the encrypted verification request by using the data transmission key of the personal device;
returning the second personalized information writing result to the upper computer via the security channel specifically is that encrypting the second personalized information writing result by using the data transmission key and returning the encrypted second personalized information writing result to the upper computer;
returning the time window and the dynamic verification code to the upper computer via the security channel specifically is encrypting the time window and the dynamic verification code by using the data transmission key, and returning the encrypted time window and the encrypted dynamic verification code to the upper computer;
receiving the verification result returned from the upper computer via the security channel specifically is that receiving the verification result returned from the upper computer, and decrypting the received verification result by using the data transmission key;
returning the personalization successful information via the security channel to the upper computer specifically is encrypting the personalization successful information by using the data transmission key, and returning the encrypted personalization successful information to the upper computer; and
returning the personalization failure information via the security channel to the upper computer specifically is encrypting the personalization failure information by using the data transmission key, and returning the encrypted personalization failure information to the upper computer.
