Both the above encryption device cipher round results are good, but there is also following problem：Using cumbersome, each use will be defeated
Enter password, password is easily forgotten, and usage experience is poor；Password Input is frequent, easily leakage；Cost is high, and encryption/decryption needs
Hardware circuit, and encryption/decryption IC costs are high；Leak be present in confidentiality：If using in flash memory device after user's decryption
Data, but in public places, leave halfway, there is also the scene that data can not maintain secrecy；If forgotten, data more be present
Can not secrecy the problem of；If frequently entering password, the problem of operating experience is very poor again be present.Therefore, existing product, is present
Cost is high, complex operation, and secrecy link requires the problem of high, limits being widely popularized for the product, at present also simply at some
The field that suitable environment is good in itself, user's confidential notions are high, such as secret unit, important commercial field arrange special messenger to make
With；Use environment is limited significantly and uses crowd.
Crowd, either business people or common personal user are used in general, it is necessary to a kind of easy to use,
Securely and reliably, the inexpensive secrecy movable storage device that can be effectively worked in visual line of sight in public places.Can not only have
Effect reduces the social concern that leakage of data is brought, and strengthens the secret protection of citizen, leakage of data can be reduced for commercial location ring
The business loss brought.
