The program of External Hard Disk Encryption
can be easily read and cracked through modify the program in the way of software program. So we think the hardware encryption more reliable now. The encryption of data for the entire hardware could prevent data compromised on the Storage links. Usually through a series of process: encryption conversion, additional passwords, and encryption module. Decryption process will include identification of data integrity.
External hard disk huge storage function allows us to store large amounts of data. Through a standard USB or FireWire interface, you can plug and play, anytime, anywhere on any machine which read and write data. However, in commercial activities, data can be easily stolen by unauthorized users.
Therefore, external hard disk data security become extremely important. data protection technologies used in external hard disk include a variety of data encryption and fingerprint identification, generally divided into software and hardware encryption technology, the former using software encryption, which will be dedicated encryption chip, external hard disk, from the hardware level encryption . The following description will be based on various technologies.
Such external hard disk is usually set access permissions in the driver, and requires the user to enter a password and so on. Ximeta's NetDisk Mini is such products. It has 40GB 2.5-inch hard drive 5400 RPM rotational speed writing. And built-in mini-server, implements a low-cost NAS (Network Direct Attached Storage Media) solution. By adding Ethernet ports, local area network users can move the hard disk password prompt to access the data.
When using the NetDisk Mini, users must turn off Windows Firewall, or set the data transfer mode under local area network. Then, the user will enter a software interface. You can follow the prompts to set various security parameters. But all achieve in the software environment.
Usually it will contain a series of process: the encryption conversion, additional passwords, encryption module. Decryption process will include identification of data integrity. System, the object contrast verification whether the input characteristic values of the parameters pre-set to achieve data security. At present, the encryption technology has been hard to perfection and there are many mature products on the market. System verificate weather the characteristic value is in line with pre-set parameters to achieve data security. At present, the encryption technology has been hard to perfection and there are many mature products on the market.
However, the general products also have some disadvantages, such as during loss of keys or forget your password and other human operational errors, Although the manufacturers take this into account, developed a number of remedial measures, but it still give users a lot of trouble, so biological living encryption is the most advanced international direction.
Each person's fingerprint is unique, so the application of fingerprint identification technology more and more widely. Now, it has also been introduced to the external hard disk. Itís not need to memory password or the key to save the password, and has a unique, irreplaceable. It applies to single-user and multi-user. In addition, you can also the hard disk, and give each user their own access.
With the increasing frequency of data movement, data security more critical. Whether it is military, business or personal, we are eager to hope that data is safely stored and mobile. Now, a variety of scheme include software encryption or hardware encryption that external hard disk manufacturers provided to us has been sufficient, of course, such products are not cheap.
