Abstract

The invention discloses an off-line secure data exchange method and equipment, and belongs to the technical field of off-line secure transmission of data files. The method comprises the following steps: downloading an encrypted data file from a server platform to data exchange equipment; obtaining a dynamic temporary password corresponding to the data file, and decrypting the data file in the data exchange equipment according to the dynamic temporary password; and reading the decrypted data file in the data exchange equipment to execution equipment, and processing the decrypted data file. According to the method, the stored data file is decrypted through the set dynamic temporary password, so that the security of the offline data file is improved, and the data file is prevented from being leaked.

Description

technical field [0001] The present application relates to the technical field of off-line secure data transmission, in particular to an off-line secure data exchange method and device. Background technique [0002] With the development of Internet digital marketing, there are more and more marketing activities based on rewarded digital codes. When the rewarded digital code is printed by a third party, effective means are required to ensure data security and not be stolen. It is necessary to trace the data leakage channel when it is illegally stolen. In the existing technical solution process, it includes: the printing company downloads the encrypted prize-winning digital code package from the Internet digital marketing platform; the authorized staff receives the decryption code of the prize-winning digital code package; and uses the machine code to decrypt Finally, copy the prize-winning digital code package to the industrial computer equipment to complete printing or prod...
