Android 11 is having away the camera picker to restrict opportunity geotag hijacking



Android 11 is taking away the camera picker to limit potential geotag hijacking

Android may have commenced with the mantra that builders are allowed to do anything at all as very long as they can code it, but matters have improved more than the yrs as security and privateness turned higher priorities. Just about every major update in excess of the final ten years has shuttered functions or extra constraints in the title of shielding end users, but some sacrifices may well not have been solely needed. A further Android 11 trade-off has emerged, this time taking absent the skill for consumers to decide on 3rd-get together digicam applications to consider photographs or movies on behalf of other apps, forcing people to depend only on the developed-in camera app.

At the coronary heart of this improve is a single of the defining qualities of Android: the Intent method. Let us say you have to have to get a image of a novelty coffee mug to offer by an auction application. Considering the fact that the auction app was not developed for images, the developer selected to go away that up to a good digicam app. This in which the Intent technique comes into enjoy. Developers merely develop a ask for with a number of standards and Android will prompt buyers to decide from a listing of installed apps to do the career.

However, items are going to adjust with Android 11 for applications that check with for images or video clips. 3 particular intents will stop to do the job like they utilized to, including: Online video_Capture, Image_Capture, and Image_Capture_Safe. Android 11 will now automatically deliver the pre-installed camera app to carry out these steps with out at any time hunting for other applications to fill the role.

Starting up in Android 11, only pre-installed program digital camera applications can answer to the pursuing intent actions:

If a lot more than 1 pre-installed program digital camera application is offered, the method offers a dialog for the user to find an application. If you want your app to use a particular 3rd-get together digital camera application to capture photographs or films on its behalf, you can make these intents specific by placing a offer identify or part for the intent.

Google describes the transform in a list of new behaviors in Android 11, and additional verified it in the Difficulty Tracker. Privateness and security are cited as the reason, but you will find no dialogue about what accurately designed those intents hazardous. Potentially some consumers have been tricked into placing a malicious digicam application as the default and then working with it to seize factors that must have remained private.

“… we imagine it really is the right trade-off to shield the privacy and safety of our end users.” — Google Concern Tracker.

Not only does Android 11 get the liberty of immediately launching the pre-mounted digital camera application when asked for, it also stops app builders from conveniently giving their very own interface to simulate the similar features. I ran a check with some easy code to query for the camera apps on a phone, then ran it on equipment running Android 10 and 11 with the very same established of digital camera applications put in. Android 10 gave back again a entire established of apps, but Android 11 reported almost nothing, not even Google’s very own pre-put in Digicam app.

As Mark Murphy of CommonsWare details out, Google does prescribe a workaround for developers, even though it’s not very useful. The documentation advises explicitly examining for put in camera apps by their deal names — this means builders would have to decide on chosen applications up front — and sending users to people apps right. Of course, there are other techniques to get possibilities devoid of figuring out all package names, like acquiring a list of all apps and then manually hunting for intent filters, but this looks like an about-complication.

The new habits is enforced in at minimum the current Android 11 beta launch, and it will come about to any apps no matter of no matter whether they concentrate on API 30 or something lower. We will not know nonetheless if the Android CTS (Compatibility Exam Suite) will involve this behavior or if OEMs will be allowed to improve it back to the previous rules, but it can be very likely this will turn out to be the regular heading forward.

This definitely is not a devastating improve, and for many users that currently default to their built-in digital camera, it will be fully transparent. And most apps will continue to permit customers to switch above to their preferred digital camera to get a very good shot, then add it from the gallery. Nonetheless, this means much more work for users, and it can be a kick in the pants to individuals that routinely snap profile pics with a filter or for those people that rely on G Cam ports to swap their stock digital camera. Furthermore, some applications will not allow for for diverse workflows, indicating you happen to be stuck with whatever digicam app is there.

Google attributes the improve to possible geotag hijacking

In a response to The Verge, Google defined that this alter was designed to “hold terrible actors from possibly harvesting your area.” This rationalization was also extra in an update to the list of changes in Android 11, along with additional technological details and a clarification that this does not inhibit the means to install and use 3rd-occasion digicam apps.

This is created to be certain that the EXIF site metadata is the right way processed based mostly on the spot permissions described in the app sending the intent.

To get EXIF place metadata from the pre-set up technique digital camera application when applying intents that have just one of the preceding intent actions, your app ought to declare Obtain_MEDIA_Place in addition to the Entry_COARSE_Spot or Accessibility_Good_Place permission.

If you want a certain third-party digicam app to cope with your app’s intent, you may perhaps do so by explicitly specifying the 3rd-celebration digital camera app’s offer name to satisfy the intent.

This transform does not have an effect on users’ ability to set up and use any digicam application to capture illustrations or photos or video clips instantly. A consumer can established a 3rd social gathering camera app as the default digital camera application. This adjust also doesn’t impact intent actions that launch the user-specified default camera application, including android.service camera_Secure, or android.provider.MediaStore.INTENT_Motion_Online video_Camera.

Harvesting EXIF details in this way has actually been documented in the previous when Shutterfly was caught accomplishing it in 2019. This adjust will prohibit the easiest route to hijacking site knowledge, but it leaves some workarounds like calling out to digicam apps straight or asking end users to take pics and load them from a media provider. It’s feasible Google may well have to consider extra measures to totally shut the doorway on this tactic.

James Webb Becomes a Dark Matter Pathfinder with a Little Trick



James Webb Becomes a Dark Matter Pathfinder with a Little Trick

A little trick turned James Webb into a “hunter” for dark matter🇧🇷 By detecting extragalactic light in galaxy clusters, an infrared telescope can reveal the distribution of this invisible matter and provide us with a new perspective on the universe.

Dark matter is one of the biggest problems in physics because it is the only way to interact with baryonic matter (“normal” matter, which includes everything we can observe in any way).

Scientists are confident in the existence of dark matter because it has mass and therefore interacts gravitationally. In fact, observations of galaxies, gravitational lensing, and clusters of galaxies can only be explained by adding dark matter to their surroundings.

Extragalactic light and dark matter

Astronomers today know that this invisible matter is behind the formation and evolution of galaxies. One piece of evidence (pictured below) is gravitational lensing—when a very distant galaxy is enlarged by a cluster of galaxies closest to us. But these lenses are made up of more mass than would be expected if we ruled out dark matter.

Astronomers are also detecting the presence of dark matter in X-ray (pink) and baryonic (blue) maps of various clusters of colliding galaxies (image below). The map shows a clear separation between ordinary matter and gravitational effects, which is one of the strongest evidence for the existence of dark matter.

This does not mean that dark matter appears in the images; what happens is a little more complicated, but elegant. The X-rays in this case show where galaxy collisions create temperatures in excess of a few hundred thousand degrees, creating light that comes from outside the galaxies but inside the cluster.

This light is called “intergalactic light” because it comes from stars and other phenomena, including matter colliding in galaxy mergers, outside of individual galaxies. But not all intergalactic light is the result of only these processes with baryonic matter.

When galaxies interact within clusters, stars and tidal currents are removed and sent away from the galaxies they belong to. Although we cannot distinguish these individual stars, they still glow, emitting a faint intergalactic light.

As dark matter gravitationally pulls on these stars, light evolves as a dark matter trailblazer, as is the case with the Tadpole galaxy. Its massive tail is evidence of tidal interactions – when some kind of gravitational force pulls and stretches galactic matter, forming a filament that contracts under its own gravity, forming stars.

In the case of the Tadpole galaxy, the tail is roughly 280,000 light-years long, and it shows the stars, following the distribution of dark matter in that region, creating intergalactic light.

Despite the possibility of detecting dark matter with these methods, telescopes have so far not been able to provide enough detailed data for an even deeper study. This may change with the James Webb telescope.

James Webb discovered dark matter

In a new study published in Letters from an astrophysical journal researchers Mireya Montes and Ignacio Trujillo used the James Webb telescope with the method of observing intergalactic light to study dark matter.

The pair used the first deep field image from JWST and calibrated the data to extract more information about intergalactic light. In the three-frame animation below, we see the original deep field image, a color inverted version, and a version with enhanced contrast/brightness to enhance intergalactic light.

They found light created by light fusions and additions caused by external factors. There are many lights coming from outside the cluster of galaxies and entangled with the light within the cluster, but the duo managed to separate them all and eliminate the luminosity of the outer objects.

The remaining light suggests that galactic mergers within clusters are the primary source of star-forming intergalactic light. Because the matter that emits this luminosity responds to dark matter, the authors of the study showed that the dark matter tracking method is superior if James Webb’s data is used.

This technique has already existed with other infrared telescopes, but James Webb is the most powerful of them all. That is: we may have a lot of news about the dark matter of the universe in the near future.
