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

WhatsApp provides multiple 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 sending files in original quality and for sharing images with sensitive information, like location coordinates.

The most common way to send an image via WhatsApp is through the ‘Attach’ button, which gives users the option to choose content from the camera or gallery. However, WhatsApp automatically compresses images when sending them, resulting in a loss of resolution. To address this issue, WhatsApp launched the option to send high-quality (HD) photos, which allows users to send images without losing resolution. Additionally, there is an option to send images as documents, which allows for sharing files up to 2GB and original quality photos and videos.

While these options prevent the platform from reducing the quality of the content, they carry the risk of sharing sensitive data, such as location coordinates, through image metadata. The EXIF data stored in images can reveal information like the resolution, file type, date and time the photo was taken, and more. To avoid sharing this information, users can use third-party applications to modify or remove EXIF data. Furthermore
