What are the principal defining elements of technocrime?

"Technocrime" is not a legal term with a defined meaning. 
Instead, it is more of a popular term used to refer to certain types of crime.  The term
"technocrime" is more or less interchangeable with the term "cybercrime."  Both terms
refer to crime that is committed by use of computers and, typically, the internet.
Because of this, they are also known as "computer
crime."

There is an academic sense of the word
"technocrime" that is somewhat broader than "cybercrime" or "computer crime."  People
who use the term in this way are referring to the idea that technology in general has
changed the way in which crimes can be committed.  They also use the term (strangely
enough) to refer to the idea that technology has changed the ways in which crimes can be
detected.

You should be sure to determine whether you are
supposed to be using the more popular definition of this term or the more academic
one.
