Innefu’s USB Tokens are designed to securely store an individual’s digital identity (digital ID), specifically their AuthShield digital certificates and keys.

How USB Token Works

These portable tokens plug into a computer’s USB port either directly or using a USB extension cable.

When users attempt to login to applications via desktop, VPN/WLAN or Web portal, they will be prompted to enter their unique PIN number. If the entered PIN number matches the PIN within the AuthShield USB Token, the appropriate digital credentials are passed to the network and access is granted.

The product is integrated with our Disk Level Encryption software which encrypts the entire file system. To read encrypted data on the disk the user needs to insert the USB Token.

File are copied to or read from the encrypted disk like any normal disk.

When a file is saved on the encrypted disk it is automatically encrypted. The encryption takes place in the RAM just before the file is written on the hard disk. All kinds of files can be encrypted including .avi files, documents, presentations etc.

Similarly, when a file is to be read from the encrypted volume, the user has to enter the USB Token to decrypt the data.

The decrypted data is never stored on the disk unless the encryption is removed permanently which can only be done by the system administrator.

The system takes advantage of a pipeline architecture which allows data to be read and written as fast as if the drive was not encrypted.

Advantages of USB Token:

  • Secure data by encrypting it before it is written to the disk
  • Decrypt data when it is read from the disk
