iStorage Assigned Two Patents

Portable encryption device with multiple keys
iStorage Ltd., Middlesex, Great Britain, has been assigned a patent (12250318) developed by Michael; John, London, Great Britain, and Xu; Quan, Middlesex, Great Britain, for a “portable encryption device with multiple keys.“

The abstract of the patent published by the U.S. Patent and Trademark Office states: “A device (100;120;140) and method (600) for storing encryption keys are provided. The device comprises: a first connector for connection to a computer, an internal memory (104); an input module (101); and an authentication module (103) for receiving user identification information, via the input module, from a user. The authentication module is configured to check received user identification information against stored user identification information stored on the internal memory to determine if a user is a valid user. A first data encryption key, DEK, is stored in encrypted form on the internal memory and is associated with the stored user identification information of a first plurality of user identities, and a second DEK is stored in encrypted form on the internal memory and is associated with the stored user identification information of a second, different, plurality of user identities. When a user enters user identification information corresponding to stored user identification information of one of the first plurality of user identities, the authentication module is configured to decrypt the first DEK for use by the user. When a user enters user identification information corresponding to stored user identification information of one of the second plurality of user identities, the authentication module is configured to decrypt the second DEK for use by the another user. Each decrypted DEK may be used for the encryption and decryption of data. Further DEKs may be stored on the device, each further DEK associated with a respective plurality of user identities.”

Multiple factor authentication for portable memory storage system
iStorage Ltd., Middlesex, Great Britain, has been assigned a patent (12184783) developed by Michael; John, London, Great Britain, for a “multiple factor authentication for portable memory storage system.“

The abstract of the patent published by the U.S. Patent and Trademark Office states: “A method of configuring a controller 14 for controlling access to a memory 12 is provided. The controller 14 has a display 18 configured to selectively display a plurality of different input screens, wherein each input screen has a unique code associated therewith and the input screens are for receiving user credentials from a user. The method comprises the steps: a) inputting to the controller 14 a plurality of authentication factors required to access at least a first portion of the memory 12; b) generating, by the controller 14, a first encryption key for encrypting data stored on the first portion of the memory 12; c) displaying a first input screen at the display 18; d) entering first user credentials to the first input screen and storing the first user credentials as a first factor of authentication; e) displaying a second input screen at the display 18; f) entering second user credentials to the second input screen and storing the user credentials as a second factor of authentication; g) encrypting the code for the second input screen using the first user credentials; and h) encrypting the first encryption key using at least one of the user credentials. A method of gaining access to the memory 12 is also provided in which the code for each subsequent input screen is decrypted using user credentials provided at the previous input screen. A method of authenticating a user and a device configured according to the method are also disclosed.”
