The need for efficient, widespread and reliable security and user privacy technologies is important more so than ever before. This is in particular crucial for workflows involving image data. Images can be easily edited to give a false impression of reality, leading to the growing challenges in the spread of fake news. But images are also creative works that are subject to copyright and integrity verification. Therefore, the ability to prove when, where or how a specific image was captured and tracing it through its workflow is crucial. To provide an answer to the above-mentioned challenges, the JPEG Committee has been working on a standard called JPEG Privacy and Security. In addition, more recently, the JPEG Committee has initiated an exploration activity to identify the needs for standardization in the realm of media blockchain applications. This paper presents the scope and implementation of the JPEG Privacy and Security standard and introduces the current state of the exploration study on standardization needs for media blockchain applications.
