Description
Technical field
The present invention is the portable electronic data erasing apparatus based on USB flash disk, relates to electronic data and wipes the field, is specifically related to the electronic data scrub techniques field based on USB flash disk.
Background technology
Annual nearly millions of the disks of China need be eliminated because reason such as damaging, too outmoded, more USB flash disk needs to destroy, so huge destruction scale if can not cooperate effective ladder of management and technological means, certainly will cause the unthinkable consequence of divulging a secret.
Data destroying technology at the beginning of being born in 21 century is the formation sign of confidential data information security field integral framework, if " data recovery technique " likened to " lance " of confidential data information security field, " data destroying technology " is exactly " shield " of confidential data information security field so, and the effect of " shield " is better than " lance ".
Present stage common data destroying mode be that data override, demagnetization, disk body destroy three kinds of modes and separately carry out, and destroys thoroughly inadequately, and destruction speed is slower.
It is the process that has the memory location of sensitive data before unclassified data are write that data override.Data on the disk are all with binary " 1 " and the storage of " 0 " form. and use predefined meaningless, irregular information to cover the data of original storage on the disk, override the back fully and just can't know that original data are 0 or 1, have also just reached the purpose that clears data.Adopting data of different types, to the method that the memory location of the data that will delete repeatedly overrides, is the effective way of data destroying, and the disk after the processing can recycle.
Demagnetization operation realizes by degausser usually, and the principle of work of degausser is that magnetic-based storage media such as disk, tape are applied the moment high-intensity magnetic field, and the magnetic-particle polar orientation of dielectric surface is changed, and loses the meaning of expression data.The most outstanding characteristics of demagnetization are exactly quickness and high efficiency, and convenient monitoring and audit can be operated in the Office Area.Disk after the demagnetization can not directly use, and can be used for after service or abandons.
Disk is destroyed the method that adopts physical damage or chemical corrosion usually the physical support that records confidential data is destroyed fully, thereby fundamentally solves the problem that data are revealed.
More than have only through the disk behind the data erase in three kinds of methods and just can recycle, therefore data erase has also become the technology of most economical practicality in the data destroying technology, but existing domestic and international data erasure apparatus ubiquity function singleness, carries the problem that inconvenience and operating result can't be determined.
Summary of the invention
The present invention provides the portable electronic data erasing apparatus based on USB flash disk in order to solve available data erasing apparatus function singleness, to carry the problem that inconvenience and operating result can't be determined.
Based on the portable electronic data erasing apparatus of USB flash disk, it comprises: USB flash disk;
