Sending Confidential Data to Users via WhatsApp: Sharing HD Photos or Documents

WhatsApp is a popular messaging platform that provides users with various options for sending files. These options include sending files from the gallery, HD images, and attached documents. While these options are useful for sharing original quality images and documents, they also carry the risk of sharing sensitive information through image metadata.

To avoid sharing sensitive data, users can modify or remove EXIF data using third-party applications. It’s essential to be cautious about sharing images with embedded location data, as this information can reveal the resolution, file type, date and time the photo was taken, among other things.

If an image is shared in HD or as a document through WhatsApp, the EXIF data is retained. Recipients can access this information through applications like Google Files, which can display the coordinates of where the photo was taken. This poses potential privacy risks if shared with others.

The most common way to send an image via WhatsApp is through the ‘Attach’ button, which gives users the option to choose content from their camera or gallery. However, WhatsApp automatically compresses images when sending them, resulting in a loss of resolution. To address this issue, WhatsApp launched an option to send high-quality (HD) photos and documents that allow users to share files up to 2GB while maintaining original quality photos and videos.

While these options prevent the platform from reducing the quality of content
