specific Embodiment

[0025] Concrete embodiment, a kind of bid shield (dedicated storage carrier for bidding (bidding) documents):

[0026] On the hardware, a USB master chip is used to communicate with the host, NAND flash or other semiconductor memory chips are used to store data content, and a liquid crystal display is used to display information on bidding (bidding) documents. The data is encrypted before being stored, and is directly written on the physical sector during storage.

[0027] When the device is recognized by the host, it regards itself as a removable disk, but the displayed disk capacity is only 512 bytes, and a file system cannot be established on it. Therefore, the device cannot be read and written by ordinary Windows programs, thus preventing harmful programs such as viruses and Trojan horses from being hosted on the device.

[0028] like figure 2 As shown, when reading and storing electronic bidding documents (or electronic files in a specific format), there is a special s...

Abstract

The invention discloses a special storage medium of specially-formatted documents and an application thereof. The special storage medium comprises a controller, a memory, an identification device, an indicating lamp or an LCD and one or more of USB interfaces, wherein the memory, the identification device and the indicating lamp or LCD are separately interact information with the controller; and the controller controls the USB interfaces to communicate with an external host. The special storage medium of the invention has better stability, higher speed, and better safety and anti-virus effect. When the special storage medium is used for the storage, transmission and reading of the bidding documents or other specially-formatted files, the bidding documents can be safely and reliably stored and fast read, and problem that when reading bidding documents, the system is infected by pernicious programs can be prevented.

Description

technical field [0001] The invention relates to an electronic storage technology, in particular to a dedicated storage carrier for electronic files in a specific format and its application. Background technique [0002] In the electronic bidding work, the storage, transmission and reading of bidding (bidding) documents have high technical requirements: [0003] The reliability and confidentiality of the stored files are very high during storage and delivery; when opening bids (reading), the storage carrier is required to be free of any viruses; when opening bids, the speed is required to be very fast, such as importing files exceeding 100G within 30 minutes . [0004] In the prior art, optical discs and U disks are mainly used as carriers for storage and delivery of bidding (bidding) documents. [0005] Because the CD cannot be rewritten after writing and curing, to a certain extent, the file is prevented from being infected by viruses again. However, CDs are relatively p...
