kudos:1 | Can you TURN OFF Webcam and audio in Silverlight? If I hadn't downloaded Silverlight I wouldn't have noticed its privacy policy about automatically storing web data in the application and performing automatic updates. I changed those, but
It also has a tab for a default capture. I found myself on the webcam - not happy about that - and all I could do was switch the default to the Lenovo easy camera.
Is there any way to turn off the web camera splitter and the audio - there isn't anything within the tab setting to do this.
These tactics may be worse than Adobe Flash, since you can turn all of that off in Flash.

kudos:7 | Webcam and Microphone
Silverlight allows webpages and applications to access the microphone and webcam. For webpages and sandboxed out of browser applications, Silverlight will display a dialog asking the user's permission to use the microphone/WebCam before allowing the application access to the device. For trusted applications, Silverlight does not display a dialog (however, the application may choose to display its own message).
Silverlight provides settings to disable the use of webcam and microphone. When this setting is disabled, no Silverlight application may access the webcam or microphone, and the dialog asking the user for permission is not shown. This setting is available in the custom ADM or ADMX file you create using the text provided at the bottom of this page. The registry setting for disabling webcam and microphone that the administrative template files contain is:

Firefox -> add-ons -> plug-ins -> click disable Silverlight Plug-in.
For those with a built-in webcam in their computers, disable it when it isn't in use! I cannot stress this more. It isn't unheard of that hackers can get access to someone's webcam and then defame them across the internet. So other than closing the lid when you aren't using the computer, what can you do? I will teach you how to disable the webcam at the hardware level.
Search -> control panel -> hardware and sound -> device manager -> imaging devices ->
In the drop down, right click the webcam and press "disable". When you want to go on webcam with someone, do the same but click "enable". It is as simple as that.

Re: Can you TURN OFF Webcam and audio in Silverlight? I don't consider it to be a security issue in silverlight..but you can turn it off...or better yet don't even install the Silverlight stuff..I use skype and it also has "setting" in options were you can can see yourself in the chosen webcam and see the audio bar moving when you select the microphone. But that does not mean anyone else has access until you give permission over the internet. Never yet heard of any hack that can turn a camera on without the light coming on in anycase.

Yes it does prompt..guess you are not reading...It also prompts you to turn off your caps so you don't waste paper and ink.
BTW just when did your flash thingie popup and want to use your mic..do you have a link..been all over the net and that never happened to date.

I always get "Connection failed" when I try to record.
You are probably behind a restrictive firewall. This is very common if you are connecting from a school or workplace. Vocaroo currently requires TCP ports 1935 to 1938 to be opened on your network.
Error
Nothing was recorded. Please ensure you are close enough to your microphone and your microphone is configured correctly.

You are 'on' the webcam because the configuration dialogue is showing you what the selected webcam will see. That seems like a pretty sensible UI design feature. This does not mean that the webcam is accessible to web sites. |

How does one do that with Mac OS X though? Also, what about microphone/mic?

Trusted and sandboxed applications in Silverlight 4
Application developers are constantly pushing the boundaries between Web applications and client applications. We want our Web apps to work more like client apps and vice versa. But Web application developers must face the security implications inherent in the Web deployed model. The big question, how much trust should be granted to an Internet application?
Silverlight is a great case in point. Imagine that your Silverlight application requires access to the user's webcam or you wish to write files into the My Music folder. Silverlight is a Web technology, or at least is deployed via a browser. To mitigate security concerns Silverlight is constrained to run in a sandbox. This sandbox restricts what the Silverlight application can do to the local computer. This is sensible as administrators need assurance that Silverlight applications won't commandeer the system. But this also means that sandboxed applications are walled off from accessing local devices, like hard drives and webcams for example.

Thanks for the info. Is it possible to have Windows 7 list any trusted Silverlight apps on your system? I know I didn't install any myself, but it is still good to check. |

kudos:1 | Thank you Name Game for providing all of that information.
When I checked the Device Manager, under Imaging Device I have Lenovo Easy Camera listed. Under the heading of Sound, Video and Game Controllers I found Cyberlinks webcam (or something similar) I'm not on that computer right now. Instead of disabling both of them I think I'll use the Black Electrical tape on the lens and switch the setting back to using the webcam.
Dave said I only saw myself because the UI was showing me what the webcam would see. it seems to me that the only thing the webcam would see is what the lens is point to - me or another user. I don't know what Silverlight needs that for.
At this point I have Silverlight version 5 on two computers. I don't know if that's good or not. The other pc has version 4.
I was looking at that Telerik weather station. When I went to the second link (said demo) It didn't load - I found out that's because I had disabled websites from storing on this computer. In any event the only download I found was at the bottom of the page -a down arrow icon which would have installed it I guess. I was hoping for an offline installation file. I have NoScripts and DefenseWall on this computer which I'm pretty sure prevented it.
Thank you again. I'll get that tape.
Sincerely, Libra |
