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

WhatsApp offers a variety of options for sending files, including from the gallery, HD images, and attached documents. The latter two choices are useful for sharing files in high resolution and sensitive information like location coordinates.

To send an image through WhatsApp, users typically use the “Attach” button to select content from the camera or gallery. However, WhatsApp automatically compresses images during transmission, resulting in a loss of resolution.

To address this issue, WhatsApp introduced the option to send high-quality (HD) photos and documents, which preserve original resolution. However, these options also carry the risk of sharing sensitive data through image metadata. EXIF data stored in images can reveal information such as resolution, file type, date/time taken and more.

To prevent sharing this information, users can utilize third-party applications to modify or remove EXIF data. It’s essential to be cautious when sharing images with embedded location data since recipients can access this information using apps like Google Files. This could potentially put privacy at risk if shared with others.

If an image is sent in HD or as a document through WhatsApp, the EXIF data remains intact. Recipients can view this information using apps like Google Files that display where the photo was taken’s coordinates. To avoid sharing images with embedded location data, users can adjust their device’s camera settings before taking photos or shooting videos.

In conclusion, while sending files through WhatsApp offers various options that help preserve original quality and share sensitive information safely, it’s crucial to be aware of the potential risks associated with sharing images with embedded location data and take necessary precautions to protect privacy while using messaging platforms.
