New technologies and devices are coming out every day along with the rapid growth of the internet and enhancement of hardware performance. These trends are connected and tangled with each other. This era of "Smart" brings us great benefits and convenience, but there are still many technical hurdles and interface obstacles to be crossed. Now we are able to access massive amount of data, but at the expense of privacy and security. How can we untie this knot? We all strive for the same goal: “to make people’s lives better,” no matter how we define our role in life.
