PowerPoint Privacy: How to Remove Hidden Properties and Personal Information

With the increasing awareness of online privacy, it is essential to keep your personal information secure while using digital tools. Microsoft PowerPoint is a popular presentation software that allows users to create professional and interactive slides. However, when sharing PowerPoint presentations, there is a risk of exposing sensitive data in the form of hidden properties and personal information. In this article, we will discuss how to remove hidden properties and personal information from PowerPoint presentations.

What are Hidden Properties?

Hidden properties in a PowerPoint presentation refer to the meta-information embedded in the file. This includes details such as author name, document title, creation date, and modification date. Hidden properties also include any comments or notes that may have been added during the creation of the presentation. While these details can be useful for personal reference, they can also be a gateway for hackers or cybercriminals to access personal information.

Case Study: The Sony Hack

The Sony hack in 2014 highlighted the importance of removing hidden properties from digital files. In this instance, hackers gained access to sensitive personal information of Sony employees, including emails, passwords, and personal identification information. The leaked data included PowerPoint presentations that contained hidden properties such as the creator’s name, comments by participants, and date of creation. The hidden properties in these files were used by hackers to identify and target individuals for phishing attacks.
