Encrypted custom usb drives

The encrypted USB flash drives refers to USB flash drives that have encrypt and decrypt functions, so they can protect their contents. There are currently three main types of encrypted custom usb drivess on the market: A. Fake encryption: only hide file, set password, and verify identity, but there is no change in the actual storage content. B. Soft encryption: with a built-in or attached software to encrypt data, AES is generally used, and can also be divided into encrypted area and non-encrypted areas. C. Hardware encryption: with a built-in encryption hardware, transparent encryption, complete encryption invisibly, verify identity while reading, and some of them have some special functions, such as applying encryption to the hard disk, clear code is displayed when custom usb drives is plugged, and encrypted information is displayed when unplugged.

Series Model

Fake encryption

Fake encryption does not realize actual encryption. You can read the original files on the USB flash drive through a password cracking tool or install the drive on another PCB board. Thus, it is poor in security.

Soft encryption

Soft encryption means encrypting the contents of the USB flash drive through a built-in or attached software. It generally adopts the AES algorithm, so it can prevent the drawback of false encryption, whose original files on USB flash drive can be read out by using a password cracking tool or installing the drive on other PCB boards. But since its encryption process is completed on the PC side, there is still a certain hidden security risk of information being intercepted.

Hardware encryption

Hardware encryption refers to encryption through the control chip inside the custom usb drives, which can realize actual time encryption. The entire encryption process is completed inside the custom usb drives, and the entire encrypted custom usb drives is black boxed. The advantage of this method is that the security level is very high, but the disadvantage is that it requires a special hardware encrypt and decrypt chip to perform encryption, and the encryption and decryption speed must reach 25MB/S or above, so the cost of hardware encryption is slightly higher than that of soft encryption.

Custom usb drivess with hardware encryption technology have the highest security level and require physical methods to achieve encryption and decryption functions. These custom usb drivess on the market are currently divided into two categories:

Fingerprint Encrypted custom usb drives


It has a built-in fingerprint acquisition/recognition device. Everybody’s fingerprint is unique and remains the same in his or her entire life. Relying on this uniqueness and stability, a person can be matched with his fingerprint to verify his or her true identity, and data encryption and decryption functions can be realized through this method.

The advantage of this method is that the security level is extremely high and the encryption/decryption speed is fast, but the disadvantage is that the fingerprint of some people or group have few fingerprint features and are difficult to image.

Key-press encryption custom usb drives

It has built-in physical number/letter keys, and the encryption/decryption function is realized by manually inputting the preset password. The password is stored in the encryption chip, so it can realize encryption and decryption without computer, and it supports multiple accounts (administrators, ordinary users) and multiple permissions (read-write, read-only) and other functions at the same time.

The advantage is that its security level is high, and can realize encrypt/decrypt data in actual time. The disadvantage is that the password must be kept in mind at all times, because once you forget the password, those data cannot be retrieved by other methods.

1. Fingerprint encryption custom usb drives

It has a built-in fingerprint acquisition/recognition device. Everybody’s fingerprint is unique and remains the same in his or her entire life. Relying on this uniqueness and stability, a person can be matched with his fingerprint to verify his or her true identity, and data encryption and decryption functions can be realized through this method.

The advantage of this method is that the security level is extremely high and the encryption/decryption speed is fast, but the disadvantage is that the fingerprint of some people or group have few fingerprint features and are difficult to image.

2. Key-press encryption custom usb drives

It has built-in physical number/letter keys, and the encryption/decryption function is realized by manually inputting the preset password. The password is stored in the encryption chip, so it can realize encryption and decryption without computer, and it supports multiple accounts (administrators, ordinary users) and multiple permissions (read-write, read-only) and other functions at the same time.

The advantage is that its security level is high, and can realize encrypt/decrypt data in actual time. The disadvantage is that the password must be kept in mind at all times, because once you forget the password, those data cannot be retrieved by other methods.

3. Iris recognition encrypted USB flash drive

It has built-in iris collector and character encryption software. The iris of each person's eye is unique and will remain the same in his or her entire life. Relying on this uniqueness and stability, a person can be associated with his or her iris to verify his or her true identity, and data encryption and decryption functions can be realized through this method.

The advantage of this custom usb drives is that the security level is very high, and the encryption/decryption speed is fast, but the disadvantage is that the you have to remove your glasses for it to quickly identify your identity.
