Image manipulation is a powerful technique that can alter the appearance or meaning of an image. It can also be used to deceive or mislead others by changing the context of an image. 

One way to do this is by manipulating the images metadata, such as the location, device, time, or date of the image. This can drastically affect how the image is interpreted by others. To prevent this, you can use Evidential, which captures images and their metadata, and uploads them immediately to ensure authenticity. The images can be viewed directly from Evidential, providing proof of their authenticity.

Evidential is a camera app that securely uploads photos to the Evidential web service as soon as they are taken. This prevents any editing of the image or its timestamp. Users can share secure access to the image and its meta data through a web link, which proves the authenticity of the image as there is no possibilty to modify the image once taken.

Evidential is a useful tool for numerous situations that may require the authenticity of an image to be proved. Some examples are:

• The state of a property when leaving or arriving

• The condition of the road after a collision

• The state of a hotel room

• The packing of a package when handing it to a courier

• The evidence for an insurance claim

• The evidence for a legal dispute
