INTERNET SECURITY ISSUES
The Internet is an amazing new frontier of human interaction. Almost anyone and anything can be found there in one form or another. This is part of the appeal of gaining access to the Internet and the World Wide Web. It???s like having the world???s largest library in your own home.
However, the public and free nature of the Internet can raise some of the same concerns for one???s personal security that any public activity might generate. This includes security of your system and its files, your identity and that of your family and friends, and the data you send over the Internet. The security of those receiving information from you is also to be considered.
Your BigpictureTM package allows you to tap into the Internet???s vast resources for exchanging and accessing video imagery, voice information, and other data. While 3Com cannot be responsible for any injury to your security or privacy or any security difficulties you may encounter resulting from your use of your Bigpicture equipment, we are concerned about our customers??? security and thus would like to make you aware of some possible ways you can manage your privacy in this dynamic arena.
???Use security features built into any Internet based software that you use. It is important to realize that the Internet is not a private

INTERNET SECURITY ISSUES
communications path. It should be considered a public ???place.??? Therefore, you should assume that any information that you send over the Internet can be viewed by strangers. If the software you are using includes security measures, we recommend that you take advantage of them.
???Use a dynamic IP address when using the Internet. When you are transferring information on the Internet, you are sending out information about your Internet address, often when you don???t even realize it. This can be helpful when you are dealing with family, friends, or business relationships. However, a stranger might just as easily tap into your address
and use it to send you information that you do not wish to receive.
VDOPhone appears on the
31
INTERNET SECURITY ISSUES
The information that you provide here will be available to anyone accessing the VDO directory while the VDOPhone software is running on your PC. Adding information to the VDOPhone ???Identity??? section might help friends and family identify who you are for practical reasons. However, keep in mind that someone you don???t know can use your information to call you and send you information that you may not want.
The best solution for this potential problem is to talk to your Internet service provider (ISP) about obtaining a dynamic IP address. Dynamic IP addresses change with every call to your ISP. What they allow you to do is to send and receive information over the Internet that can be traced. If someone were to intercept your
dynamic address, they could send to that address, but it would only be valid until your next log in. It will be invalid almost as soon as they have a chance to send you unwanted information. Additionally, your ISP should be able to trace who sent to your dynamic IP address at the moment you received the unwanted message or information.
Many ISPs offer dynamic IP addresses for users who are concerned about security. We strongly encourage you to obtain one and to obtain them for anyone using your Bigpicture system.
???Use vague identity information. You can fill in the information screens with a nickname, code name, or anything other
32
INTERNET SECURITY ISSUES
than your real name to ensure that no one will know who you really are.
???Use a password your children don???t know. If you have children who use your computer, you may want to keep your VDOPhone password a secret from them to ensure that they don???t have access to the software. Unsupervised, a child could access video under the ???(X) Adult Only??? category with just a few clicks of a mouse.
???Do not use an actual picture in the photo ID section of VDOPhone setup.
In VDOPhone setup, you have the opportunity to choose an ID photo of yourself to attach to your video messages.
We recommend that you NOT use an actual photo of yourself or any of your family members. This is another way you
33
INTERNET SECURITY ISSUES
can protect your identity and that of your family.
???Do not use ???Auto Answer??? when using VDOPhone. This setting automatically brings up any video images that enter the VDOPhone directory, regardless of whether you want to see them or not. By disabling this feature, you reduce the risk of seeing something that might offend you or that you do not wish to see.
???Call Screening??? enables you to see the identity information of the person calling you before you see any images.
Remember that just as you can see and hear others, they can see and hear you
unless you disconnect your camera and microphone.
Implementing these precautionary procedures are just a few ideas that may help ensure your privacy and security on the Internet. Always remain aware of the public nature of the Internet when using software that utilizes its resources.

TROUBLESHOOTING AND ONLINE HELP RESOURCES
NOTE: If your PC is loaded with many devices, there may not be a free interrupt available for the video capture card. If this is the case, you???ll need to find an unused device which has a reserved interrupt and free that interrupt for use by the capture card. Many PCs reserve an interrupt for a PS/2 mouse or an IDE hard disk controller, even when these devices are not present on the system. If an interrupt is reserved for a device that you know is not present on your system, that interrupt can be reserved for your video capture card.
4.Go into your BIOS and disable the peripheral not being used (i.e., the PS/2 mouse or IDE controller mentioned in the preceding sidebar).
