user33746: What are the privacy techniques that used with Litecoin? and what are the differences between Bitcoin and Litecoin in privacy techniques? 

user5406: There is no substantial technical difference between Litecoin and Bitcoin transactions.
Litecoin does not offer any additional "privacy techniques". The only differences are: 

address scheme: Litecoin addresses start with an L, Bitcoin standard addresses start wtih a 1.
Volume: Bitcoin volume is much higher, so it might be easier to obscure a payment among the other transactions.
Attention: Bitcoin might have more attention of law enforcement.

Note: The last two points are based on speculation.
