A digital asset is anything that exists only in digital form and comes with a distinct usage right or distinct permission for use. Data that do not possess those rights are not considered assets. Digital assets include, but are not limited to: digital documents, audio content, motion pictures, and other relevant digital data currently in circulation or stored on digital appliances, such as personal computers, laptops, portable media players, tablets, data storage devices, and telecommunication devices. This encompasses any apparatus that currently exists or will exist as technology progresses to accommodate the conception of new modalities capable of carrying digital assets. This holds true regardless of the ownership of the physical device on which the digital asset is located.

In the present book, ten typical literatures about Digital assets published on international authoritative journals were selected to introduce the worldwide newest progress, which contains reviews or original researches on Digital assets. We hope this book can demonstrate advances in Digital assets as well as give references to the researchers, students and other related people.
