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

WhatsApp provides a variety of options for sending files through its platform. These options include sending files from the gallery, HD images, and attached documents. The latter two options are useful for sharing files in original quality and for sharing sensitive information, like location coordinates.

To send an image via WhatsApp, users can use the ‘Attach’ button to select content from their camera or gallery. However, WhatsApp automatically compresses images when sending them, which reduces the resolution. To address this issue, WhatsApp introduced the option to send high-quality (HD) photos and documents that preserve the original quality of the content.

While these options prevent the platform from reducing the quality of the content, they carry the risk of sharing sensitive data through image metadata. EXIF data stored in images can reveal information like resolution, file type, date and time taken and more. To avoid sharing this information, users can use third-party applications to modify or remove EXIF data. It is crucial to be cautious when sharing images with embedded location data as it poses potential privacy risks if shared with others.

If an image is shared in HD or as a document through WhatsApp, EXIF data is retained. Recipients can access this information using applications like Google Files that display coordinates where the photo was taken. It’s essential to be mindful of what information is included when sharing images through messaging platforms to avoid any potential privacy risks associated with these features.
