There are numerous secure camera apps on the market, some of which are designed to record sensitive information such as human rights violations. However, if you are taking photos and videos in the hopes of convicting perpetrators in court, then not all camera apps are up to the task. The reason is courts require proof that the footage shows what you claim it does. A specialised camera app can help with this. However, if you use an app that is not designed for legal proceedings, your videos and photos could be disregarded as unreliable. Very often, unreliability comes down to discrepancies and errors with the photo or video’s metadata.
Metadata summarises a photo or video’s basic information. For example, the footage’s time and location, and the device it was taken with. Metadata is important because it can verify that the footage was taken when and where the photographer says it was. It can also show that the footage has not been tampered with. Accurate and unaltered metadata is fundamental to reliability. As such, you need to choose a camera app that captures metadata in the right way.
The not-for-profit eyeWitness to Atrocities developed its eyeWitness app to meet this challenge. As the only secure camera app created by legal experts, the eyeWitness app collects and stores metadata in a unique way that adheres to the toughest legal requirements. It also helps to protect its users’ identities by not collecting personally identifiable information.
This article outlines what metadata eyeWitness collects; how eyeWitness captures, stores and transmits metadata; and, finally, how eyeWitness protects your privacy.
Our extensive legal research has identified that the key information for verification includes the footage’s location, date and time.
We also know that more metadata is not always better when it comes to use in court. The opposing counsel could use any incorrect or inconsistent metadata to discredit the integrity of the footage itself. As such, the eyeWitness app does not capture information that cannot be recorded consistently.
For these reasons, the eyeWitness app collects the following:
Many camera apps capture similar data. However, as explained below, not all apps capture it in a way that stands up in court.
One of the biggest problems with camera apps (including the standard camera on your phone) is that they do not always record location, time and date accurately. Here are common problems with some camera apps:
To overcome these problems, eyeWitness does the following:
eyeWitness presents all of this complicated raw data in a clear, readable format for its partners. We even plot GPS, WiFi, and cell tower locations on a map.

Altitude is an example of unreliable data. Because mobile devices are not altimeters, they are not capable of recording altitude with accuracy. Similarly, other data points such as speed or bearing are not helpful in demonstrating your footage is reliable.
As we have said, courts require proof that no one has tampered with the footage at any point. In legal terms, this is called protecting the chain of custody. This is due to the risks of individuals editing and altering media and data to create fake evidence. If your camera app allows you to export and download your footage and metadata, then you have the ability to change them. The chain of custody is broken, and they will no longer be reliable on their own. Consequently, they will require corroboration such as your testimony in court.
eyeWitness guarantees that all footage cannot be edited or altered, thus ensuring the chain of custody is intact. It does this in four ways:
Firstly, as soon as you take the footage, the eyeWitness app automatically generates a unique identifying code known as a “hash value”. This hash value serves as a digital fingerprint. This step ensures that any subsequent changes to the footage can be detected.
Secondly, eyeWitness does not allow you to upload footage taken from another camera app or device. The reason is eyeWitness cannot prove that the footage was not altered prior to being uploaded.
Thirdly, the app does not allow you to immediately download or export your footage. Instead, the app asks you to upload the original photo or video to the secure, encrypted eyeWitness server, where we can protect the chain of custody for you. Once eyeWitness receives the footage, you automatically keep a copy that you then can download and export as normal.
Fourthly, and finally, eyeWitness stores footage securely. All footage taken through the app is stored in an encrypted storage area within the eyeWitness app itself, separate from your phone gallery. The eyeWitness server that users upload their footage to is encrypted, secure, and access controlled.

Importantly, eyeWitness also provides a thorough explanation of its technology and processes so courts can understand how eyeWitness ensures the chain of custody.
When it comes to monitoring atrocities and human rights abuses, you do not want your camera app to capture any identifiable information about you.
eyeWitness does not collect any identifying information unless you voluntarily provide it. The eyeWitness app collects the following information about you and your device:
We do not collect device IMEI numbers, MAC addresses, or IP addresses from which you submit your footage.
You also need to ensure that all of your footage is encrypted and secure. As stated previously, all footage you take using the eyeWitness app is encrypted when stored and transmitted.
