CameraV: Security and reliability for your images and videos

Images taken with smartphones usually contain extra information included, known as Metadata. This information can be as basic as the time and date of the image, and as accurate as the location where the image was taken, the type of camera, environmental data, and stop counting.

Certainly, that information may be harmless, but in some scenarios, excess information in a single image or video can put a simple photo taker in danger.

In this situation, The Guardian Project, development Obscuracam, camera-type app that eliminates the information (metadata) generated in each file, in addition to automatically detecting and blurring the faces in each photo and video, maintaining the anonymity of the user.

Now, from another point of view, the generation of these metadata can be useful information for content validation, especially in these times where the known “Citizen journalism”Every time it takes more flight. All of this makes metadata important now, considering that digital image manipulation and alteration is common these days.

Once again, The Guardian Project appears, but now with CameraV, an application of open source guidance on Android, based on the platform InformaCam. With which you can take photos and videos, with content validation through the use of metadata.

It was developed by activists, journalists and lawyers, whose goal was to create an application that allows them to capture visual evidence and prove abuse and violation of rights worldwide.

CameraV is a metadata capturer, it uses the sensors that your smartphone has to obtain environmental information, as well as data from WiFi, bluetooth, and cellular networks, to store them along with the photographs taken. In this way, CameraV gets not only the image of what is happening, but also Capture the atmosphere of the photo or video. These sensors can be from:

Movement, such as accelerometers, which allow detecting the movement that occurred at the time of recording.

Position, through GPS location, providing exact coordinates where the image or video was taken.

Environmentsuch as thermometers that provide temperature information and weather-related data.

Also, CameraV stores WIFI networks and Bluetooth devices in the vicinity of the place, including location data within the mobile network, to provide a higher level of information for content verification.

This considerable amount of metadata is encrypted under PGP and shared with other people to help verify the information that is being provided, through a unique file ID, or digital signature together with the rest of the metadata, which will be sent to an email address, SMS or social network.

The ability of an app to verify the authenticity of each image is important to anyone. Although we agree that this additional information may compromise the user in some way, this same information can provide valuable evidence capable of making known what is happening at a time and place.

You can find CameraV in the GooglePlay, F-droid or in direct download from the server Github.

    This article is more than confusing.
    First you say that the program removes the metadata
    and then it becomes clear that what the program does is the opposite:
    collects a lot of metadata including our location via GPS and sends it to the cloud.
    Encrypted or not, I don't care, what people should do is clean every document of all metadata before putting it on the internet and for that there are specific programs like ExifTool

      Good morning user, I hope you can read the article again to clear up any confusion. In principle, we talk about ObscuraCam, an App from TheGuardianProject that removes all metadata from images and videos for security reasons. But then, looking at the metadata from another point of view, the idea of ​​using it as a source of content verification arises, And in this case, TheGuardianProject now creates another App called CameraV, which generates a large amount of encrypted metadata for content authentication.

      The interesting thing about the subject is that one app (ObscuraCam) is the counterpart of the other (CameraV), and it will depend on the application or the user's need to use one or the other.
