Abstract

The invention discloses an intelligent memory card with an embedded CPU IC and an application thereof. The intelligent memory card comprises a central controller, an internal memory, an input device,an output device and an encryption system. The power supply is connected, an electronic calculator is opened, the USB flash disk is inserted into the electronic calculator; the USB flash disk is inserted into the electronic calculator; the cryptographic software is opened, an account is registrated by encryption software; after theregistration is completed, a safe box is created on an encryptionsoftware interface; files and photos needing to be encrypted are copied into the safe box; the safe box is encrypted; after encryption completion, the USB flash disk is pulled out, at the moment, theencrypted safe box on the interface cannot disappear; any person cannot check the small secret placed in the safe box when taking the encrypted USB flash disk, and the intelligent memory card can helpan enterprise create a healthy and efficient internet use environment on the basis of not influencing the network operation efficiency and not changing the existing network structure, and has a certain use prospect.

Description

technical field [0001] The invention relates to the technical field of smart memory cards, in particular to a smart memory card embedded with a CPU IC and its application. Background technique [0002] The CPU card is also called a smart card. The integrated circuit in the card has a microprocessor CPU, a storage unit, a user data memory, and a chip operating system COS. The CPU card equipped with COS is equivalent to a microcomputer. It not only has the function of data storage, but also has command processing and data security protection. The CPU card can be applied to many fields such as finance, insurance, traffic police, and government industries. It has the characteristics of large size, fast reading speed, and supports multiple functions of one card, and has passed the certification of the People's Bank of China and the State Commercial Secret Committee. The CPU card is no different from ordinary IC cards and radio frequency cards in terms of appearance, but there are...
