Privacy and Security for Images

Dear Colleagues,

Most of the vast amount of digital images being created, viewed, and distributed everyday follow international standards for their representation and interchange. The JPEG format, as an example, is today one of the most widely-used image standards.

There is a currently increasing trend to share images by means of social networks and cloud-based image repositories, such as Facebook, Flickr, YouTube, Instagram, Pinterest, etc. In addition, newspapers and other related websites publish digital pictures owned by photographers, readers or news agencies.

With so many digital images available, there is an increasing risk of the unintended release of privacy information. This includes not only the image itself, but also associated metadata that could contain privacy information, such as positioning. We should also not forget about the management of the digital rights of the owners of the images.

Different partial solutions have been considered, but new approaches are under consideration, including the use of new technologies, such as those related to Blockchain.

The aim of this Special Issue is to identify these privacy risks and propose solutions, which ideally should maintain interoperability by means of International Standards.

Topics may include, but are not limited to:

• Privacy and security threats in standardized images;
• Limitations and improvements of current solutions in images privacy and security;
• Standard approaches to provide images with privacy and security;
• Blockchain as a solution for privacy and security in standardized images;
• Specific privacy and security approaches in JPEG;
• Privacy in JPEG images: use cases, privacy rules, integration with format, etc;
• Digital rights management vs. privacy and security in standardized images;
• Alternatives to JPEG for improving privacy and security.
