Top 5 Security Inventions you Must Have

Perception of security may be poorly mapped to measurable objective security. For example, the fear of earthquakes has been reported to be more common than the fear of slipping on the bathroom floor although the latter kills many more people than the former.[3] Similarly, the perceived effectiveness of security measures is sometimes different from the actual security provided by those measures. The presence of security protections may even be taken for the safety itself. For example, two computer security programs could be interfering with each other and even canceling each other's effect, while the owner believes s/he is getting double the protection.
