     FIELD 
       [0002]    The invention concerns a memory system with additional functions, with which mobile data processing is made possible. 
       BACKGROUND 
       [0003]    Mobile computing is steadily increasing in importance. Oftentimes, data are carried from one computer to another in portable fashion by memory sticks (such as USB flash memory). While processing hitherto has always taken place under control of the host PC, which is to say the booting of the operating system, and thus its weaknesses and the potential for attack from a USB stick had to be viewed as a cumulative security risk, an approach is to be selected that simplifies the process of authorization and the processing of data through the use of a memory stick (such as a USB stick) and offers a higher level of security. 
       SUMMARY 
       [0004]    The present invention provides a mobile data processing device. The device includes a permanent memory configured to store an operating system stored in the permanent memory and bootable therefrom. The device includes a connection configured to connect the device and a personal computer. The connection is configured so that the personal computer loads the operating system from the permanent memory during booting. The device includes at least one integrated network adapter. The device includes a hardware system. The hardware system is configured to at least one of encrypt and decrypt a content of the permanent memory. The device includes a housing configured to enable user pocket portability of the device.

     DETAILED DESCRIPTION 
       [0008]    One embodiment of the invention includes the features of the independent claim. 
         [0009]    In principle, the key can be used in all fields that involve login processes and the processing of data using IT systems. 
         [0010]    The combination of these components:
   a. Login and security, firewall, virus protection and child protection   b. USB SLC flash memory&gt;=8 GB, preferably with multiple partitions   c. Integrated WLAN adapter   d. Integrated Ethernet chip for Ethernet connection via RJ45   e. Biometric finger scanner   f. USB memory with hardware-supported data encryption, preferably 256-bit AES ad hoc encryption
 
in a system in this form is one way of providing a maximum degree of security and independence.
   
 
         [0017]    The device is personalized and can provide primary functions such as
   a. Authentication device   b. Local data storage   c. Local work environment (operating system, selected application programs such as, e.g., MS Office, dictionaries, browser, etc).   
 
         [0021]    Access to the system and to possible Internet platforms can take place in two stages: The operating system stored on the disk (such as Windows XP or the like) boots automatically. At first startup, a personalized certificate can be issued and is associated on the server side with the finger scan. A security certificate can be required for each individual device in order to make the login process via fingerprint secure. Alternative approaches, such as the generation of a local certificate, are conceivable. 
         [0022]    In all logins that follow, the certificate and finger scan of the user take the place of the insecure and inconvenient login with user name and password. However, if the user wishes to login in the known manner with user name and password, this is made possible for him. 
         [0023]    In order to make operation as simple as possible, the device can be operated via simple USB cable. If energy consumption is greater, a USB Y-cable can be used. In the event that power is insufficient and only one USB interface is available, a USB hub with an external power supply is offered as an option. The cable can be integrated into the housing in a flexible manner. In addition, an integrated LED indicates the status of the power supply; (when the LED lights green, there is no problem; if it does not light, the power supplied through the USB port is insufficient). 
         [0024]    Furthermore, an additional LED with a red light can indicate the status of the data transmission in order to reduce the probability of any damage and data losses caused by improper handling. 
         [0025]    It is possible to integrate an SD card slot in future. The idea behind this is in the future to offer data preinstalled on SD cards, which can then be used immediately. 
         [0026]    In accordance with current technical capabilities, the first generation device can have 8 GB memory capacity in one layer. For a long service life, SLC flash chips can be used at present. However, new chip developments do not preclude a higher capacity and a different technology in the future. The possible use of a second layer PCB would make it possible to double the particular capacity. For the time being, however, 8 GB memory space can suffice. 
         [0027]    Color coding can be provided for the housing and for connections to prevent operating errors to the greatest extent possible. 
         [0028]    The WLAN antenna can be integrated in the housing. The device can be switched off with additional software through a secured Internet connection. A backup version of the local software (corresponding to the condition on delivery) is present in a partition that is inaccessible to the user, allowing the device to be reset through the network by service personnel. 
         [0029]    In one possible embodiment, it is a USB SSD with biometric fingerprint sensor
   a. SSD with minimum 8 GB SLC NAND flash chips, partitioned, ensures high reliability and speed   b. Preinstalled operating system permits the use of additional applications and booting from the USB SSD   c. 10/100 base T Ethernet and 802.11a/b/g WLAN for connection to the Internet and intranet   d. USB hub controller—fully compatible with USB2.0 high-speed   e. USB flash disk controller with biometric fingerprint sensor   f. E-field sweep type fingerprint sensor   g. The advanced fingerprint recognition technology makes it possible to log into Internet platforms with very high security and great convenience.   h. Unique identification of the user at login   i. The possible housing dimensions are
       a. 95 mm×71.5 mm×15.5 mm (H)   
       j. PCB (circuit board) size
       a. 88.35 mm×65.00 mm
 
However, these do not represent any limitation.
   
       
 
         [0042]    A maximum degree of security is provided by the invention, and all vulnerable components of the host PC remain unused and hence protected from any change. 
         [0043]    With the invention, requirements can be simultaneously fulfilled that previously could not be fulfilled or could not be fulfilled by a single device:
   a. Security through the combination of certificate (that cannot be manipulated by the user) and finger scan (only possible for the user).   b. Location-independence due to usability with any desired host PC, because only “neutral” devices thereof are used, such as working memory and processor, graphics card and screen, keyboard, and mouse, but no local drives.   c. Lighter than an ultra-mobile PC, hence “always at hand”   d. Consistency, a defined scope of user data on the key, background data and additional applications on an Internet platform, resulting in working conditions that are the same at all times and in all places   
 
         [0048]      FIG. 1  shows the individual components of the device and their connection. A central USB hub is located in the device; this communicates with the computer through the USB bus. A second USB connection, which is not shown separately here, can be used in the event of increased energy demand. In an embodiment that is not shown, a USB hub with a power supply can additionally be interposed if the power supplied by one USB connection is not sufficient. The controllers for the permanent memory, the Ethernet adapter, and the WLAN adapter are connected directly to the internal USB hub. The fingerprint sensor is connected directly to the permanent memory. The flash drive controller also has the task of presenting the flash memory to the operating system as a hard disk. The network controllers are then connected in turn to appropriate connections. 
         [0049]      FIG. 2  shows the housing with possible connections. The housing has a USB connection, a power supply connection, a fingerprint sensor, and an Ethernet connection. The WLAN antenna is integrated in the housing. The size is approximately 6.5 cm×9 cm. The location of the LED status indicators is not shown here.
