The Kids Online Guard USB Stick allows parents to restrict the times that their children can go on the computer, and can be set to prevent children accessing undesirable sites.
A website can be designated, such as an educational site, which will then be displayed when a child logs in.
To ensure that kids don’t tamper with important files a ‘privacy room’ can be set up on the computer where important data can be secured, accessible only through the USB lock.
The lock can also disable the use of CD-ROM and USB flash drives, and will provide a history of which sites children have visited.
The device costs $21.69.
