Safety issues (including security, privacy, and trust) in mobile social networks are concerned about the condition of being protected against different types of failure, damage, error, accidents, harm or any other non-desirable event, while mobile carriers contact each other in mobile environments. However, lack of a protective infrastructure in these networks has turned them in to convenient targets for various perils. This is the main impulse why MSNs carry disparate and intricate safety concerns and embrace divergent safety challenging problems.[23]
