Nowadays,it has become a need to make your blog(bloggers too) copy protected since same copies would be found some where in the internet after few hours.This happens mostly through feeds where many sites would directly publish all our content from our site’s feeds.
Prevent copying of Text from your blogger or any sites
                It is possible to prevent copying the content of our blog by just adding some piece of code which will prevent fraudulent users to select the text.Insert the code into commonly visible area for all content,better place is footer area.

var omitformtags=["input", "textarea", "select"]
omitformtags=omitformtags.join("|")
function disableselect(e){
if (omitformtags.indexOf(e.target.tagName.toLowerCase())==-1)
return false
}
function reEnable(){
return true
}
if (typeof document.onselectstart!="undefined")
document.onselectstart=new Function ("return false")
else{
document.onmousedown=disableselect
document.onmouseup=reEnable
}
</script>


Prevent copying of Pictures from your blogger or any sites

1.Look through the source code.

2.Retain only the tag, removing the rest:

for eg:

<img src="url to image file" alt="picture" border="0" />

3.Now add the following script just prior to the closing />:

oncontextmenu='return false;'


4.As an alternative, you could also pop up a message:


oncontextmenu='alert("Copy Protected."); return false;'
