Abstract

A computer system 7 permits access upon receipt of relevant security access information transmitted to it from a user portable transmitter 11. Specifically, the transmitter 11 is a blue-tooth enabled mobile telephone but it could also be a personal digital assistant (PDA) or other portable device.

Description

24 1 8759
SYSTEM ACCESS APPARATUS
This invention relates to a system access apparatus and method, particularly, but not exclusively for enabling access to a s computer.
It is important to prevent unauthorized access to computers.
This requirement is one which is employed in nearly all office and even home environments. Typically, access is controlled by requiring to the entry of a password and, usually, a user identifier before the computer may be used. Most users find this an undesirable prelude before they can start work and it is one that may have to be carried out a number of times during a working day. If the computer is not. . used for a predetermined time the security may be re-applied.... :.
Is preventing access until the password and username is re-entered.
Some more cavalier users will seeks to avoid this requirement by bypassing the security set-up by re-configuring the computer to eliminate the need to enter a password or by increasing the delay..
before security is re-applied. Thus, it is possible for a security policy : to be broken down in an organization by users actively circumventing the policy.
The present invention arose in an attempt to make system access less onerous to users.
According to the invention there is provided a computer system configured to require verification of access information before allowing use of the computer system, a receiver for receiving access information and providing the received access information to the computer system for verification, a user portable wireless transmitter for transmitting user specific access information such that when the user specific access information is transmitted it is received and, if verified, permits access to the system.
By providing a user portable transmitter for transmitting user specific access information a more convenient security policy may be to implemented. Instead of the user having to input the access information at a keyboard, it is conveniently transmitted to the computer system. ....
Preferably, the access information is transmitted when the Is transmitter is within the proximity of the computer system. Most preferred, is that the transmitter automatically transmits the access information when within the proximity of the computer system. In this way, the computer system may be ready for use when the user..
approaches the system by, for example, entering the room where the computer system is located. Alternatively, the transmission may be triggered by a user action such as pressing of a button.
The described embodiment utilises a mobile telephone with a blue-tooth capability transmitting access information.
A specific embodiment of the invention will now be described by way of example only with reference to the drawing in which: - 2 - Figure 1 shows a computer system in accordance with the invention; and Figure 2 is a message flow diagram for the computer system of figure 1.
As is shown in figurer, a computer system 1 includes a microcomputer 2 with a visual display unit 3 connected to a base unit 4. A keyboard 5 and a mouse 6 are also connected to enable user to input to the microcomputer. Also connected to the computer system 1 via a USB port, is a blue-tooth transmission transceiver 7. The transceiver 7 has a reception range of a few metres as indicated by....
the arc 8. ...
Is A user 9 has a mobile telephone 10 including a blue-tooth transceiver 11. ....
The blue-tooth transceiver 7 periodically transmits a notification..
signal advertising that a unit with blue-tooth capability is located in the go vicinity. When the user 9 enters the room where the computer system 2 is located and falls within the reception range, blue-tooth transceiver 11 responds to the notification signal.
At this point reference should be made to figure 2 which shows the flow of messages between the two transceivers 7, 1 1. Lines 12 represents the air interface between the units. Initially, the transceiver 7 sends out the notification messages 13. These are separated by a time interval of one second but the interval may be different or different for different times of day. The user enters the range 8 and the transceiver 11 receives to the notification with a message 14 indicating "I am a security token". The transceiver 7 s responds with a message 15 "provide username". The transceiver 11 responds with message 16 indicating "username = "Fred"".
Safe receipt of this information is acknowledged by an acknowledge message 17 that username = "Fred". This is followed to by a request 18 "provide password". The password "ABC 1234*" is returned in message 19 and acknowledged by transceiver 7 in message 20. A message 21 indicating the end of the log-on process..... se..
is sent by the transceiver 7. An acknowledge message 22 is sent, back in response.
The transceiver 7 then sends the username and password via the USB port to be read by a log-on application running on the computer system. If the username and password are the required.. :.
Ones for operation the user is logged on and is able to use the ho computer system 2 if desired.
If the username and password are incorrect then the computer system 2 remains in standby mode.
us It will be appreciated that the user may move about the room engaging in various activities without using the computer system 2 or only using the system for part of the time. The system may be configured to return to a standby mode if not used for a period of time in which case the transceiver 7 will return to the first stage transmitting notification messages 13. However, in this embodiment the user remains logged-on and the transceiver 7 sends periodic s messages 23. If the transceiver 11 is within range, that is, the user is in the room, it responds with a message 24 indicating the transceiver 11 is still present. If no reply is received after four of the messages 24 the transceiver 7 sends a message via the USB to the application and the user is "logged-off". The transceiver 7 then starts to transmitting periodic notification messages 13.
Whilst the described embodiment refers to a computer system, ;, in the form of a desk-top computer it could be applied to computer.
systems to permit access control or other functions.
The security access information may be held on a smart card such as the SIM card used in the mobile telephone. s l
