Now smartphones have become an indispensable tool in everyone's life, with out-of-door sweeps, navigational route, chatting with relatives and friends, and processing work-related messages, and almost all day-to-day business can be done on a mobile phone. When many people have access to the new cell phone, the default set-up is fully maintained, and very few will voluntarily look through the access switches in the system. There is a mobile phone that is self-contained, and many people, from buying a mobile phone to changing it, remain open throughout the year and feel that it is simply easy to use, without any risk。National securityThe department has repeatedly issued a reminder that if this function continues to be activated in an inappropriate setting, it will leak location, environment, equipment information and bring it inInformation securityThere are hazards, but most ordinary people are not aware of potential risks。
First, it is not said that this function itself is harmful. This function was designed to improve the ease of use of mobile phones, and it does simplify operations in the context of rational daily use. The problem arises from the fact that there is no place, no limit, no limit, and many people have never managed authority in a precise manner and have been allowed to do so. The risk of leaking information increases in a straight line once it is used by outlaws, or in secret locations, important work scenes。
This function is the location information (location) access to mobile phones. A lot of people wonder if positioning is just a way to get a receiving address for navigation, for delivery software, and why is the nsa reminding you of this function? Many people understand locational access by simply knowing where they are in the software, and mobile phone positioning actually gets more information than you can imagine. Cellular positioning relies not only on gps satellite positioning, but also on base station information, nearby wifi hotspots, bluetooth signals, which combine to calculate your real-time position, so precision can be reduced to tens of metres in part of the scene。
When many software is installed, one-time applications for permanent position privileges are made. A number of people installed apps only quickly agreed to do so, and did not read the right windows at all. Once permanent locator access is granted, even if you do not turn on the software, it can continuously access your location information in the backstage. To give a simple example, a shopping app, which you use occasionally, was installed directly to allow access to all places, and even if the software is hanging on the backstage, it can continuously track your activities. Your journeys to and from work, your frequent places and travel times are recorded on an ongoing basis, creating a complete personal track record。
There may be people who feel that my life is ordinary, that there is no sensitive information, and that even if others knew where i was going, there would be no loss. There is a lot of error in this thinking. Information on the location of the general population is also highly useful when aggregated. Illegal elements collect large amounts of data on the location of ordinary people, which can be used to analyse patterns of movement. In the case of regular access to key units, scientific research institutes, ports and military-industrial-related areas, the risk posed by the continued location of mobile phones is even greater. The offshore intelligence agencies are able to extract valuable intelligence leads by analysing the time and frequency of movement of persons in priority areas through a variety of locational data collected from various ap backstages. This is also a central reason why the national security service has repeatedly tried to regulate mobile phone positioning。
There is also a habit for many people to switch their mobile phones to silence and not close their location after entering office areas and secret spaces. In accordance with the relevant confidentiality regulations, there are strict control requirements for devices such as mobile phones, which have location, recording and photo functions. Even if you don't turn on the map software, as long as cell phone locator access is on, it's possible to collect position data from backstage. In previously publicized cases, the staff members involved entered the work area with a mobile phone that opened the location, went to and from work on a daily basis, and the long-term location tracks were collected, resulting in leaking information on activities in sensitive areas。
Let's make a distinction here. It's not like you're always turning your phone off. Fully closed positioning, and software such as navigation, cabling, take-aways, weather, etc. That requires location services cannot be used properly. The correct approach is not one-size-fits-all permanent closure, but to fine-tune the regulatory authority and withdraw it as and when required, which is also the operational approach advocated by the state of angola。
In mobile phone systems, there are generally three authorization options: always allowed, allowed during application, denied. The vast majority of people installed software and directly ticked " always allowed " , which was the most risky option. “always allowed” means that the app remains available for reading under hibernation in the backstage. "as permitted during application " , only if you start the software on your own initiative will the software be able to access the location, and it will not be able to continue reading location information once the software is backstage。
We can sort the location privileges according to the software use. Such software as map navigation, cabling software, which requires real-time location to function properly, can be set to allow for the duration of the application. Out-of-service, fresh distribution software, which requires only a receiving address and no real-time track tracking, can be set to allow only during use, or to manually fill in a fixed address, without open real-time positioning. For short video, reading, graphics, shopping software, think carefully, such software itself does not require any real-time location for you, and applications for locator privileges can be refused directly. Many of these app requests for locational access are not intended to serve you, but are based on location-based advertising and the collection of geographic data of users。
Many do not know that, in addition to having separate app locator access, mobile phones are able to view the logs of location information. Both android and apple phones use logs with their own location, which software can be viewed and which location has been called at what time. When you have time, you can turn on the privacy settings of your mobile phones, look at the location access records, and often find software that has not been open for a long time, and call quietly in the backstage. Such unusual calls are detected and their location is shut down at the first moment。
In addition to locator privileges, there are two additional privileges associated with location information, which are ignored by many and also need to be checked. The first is wifi scan access. Even if you turn the gps off, and the phone opens the wifi scan, the device will continuously scan the perimeter of wifi's hot spot name and signal strength, pushing you back through the wifi database. A lot of phones are defaulting on the wifi scan, and even if you don't connect wifi, you still scan the perimeter wireless. The second is bluetooth permissions, some of which are supported by bluetooth perimeter scanning devices, and are similarly recommended to be closed as required in software that does not require bluetooth functionality。
Next, how to regulate the use of mobile positioning in different settings。
The first scenario: daily commuters, shopping, travel. Regular outings use navigation, taxis and temporary open positioning. After the software has been used, the mobile phone location is not deliberately shut down, but it is important to ensure that such software privileges are set to " allowed during use " and do not give permanent privileges。
Second scenario: access to institutional units, scientific research institutes, plant-focused workshops, and related sites. In accordance with site management requirements, many of these places require mobile phones to be stored in designated storage cabinets and cannot be brought in. If the site is allowed to carry mobile phones, global positioning, wifi, bluetooth must be closed ahead of time, and the app backstage refreshing function must be closed to eliminate the possibility of collecting information backstage. Don't be surprised to think that you're okay without a map. Backstage collection does not need to open the software manually。
The third scenario: travel to border areas. When travelling to the border control area, the authorities specifically caution against the use of mobile phone locator cards and the uploading of watermarking photographs of their locations. Photos with location information are attached to the photo file with exif information, which records the longitude and timing of the photograph. The location information will be sent to the social platform. Many people take photographs and send them directly to the circle of friends, without knowing where they are and inadvertently leaking location information. In the mobile camera, the photo watermark can be closed separately, and this switch is recommended to be switched off on a daily basis and opened when required。
The fourth scenario: home environment. The use of mobile phones at home is relatively low risk, but it is still recommended to clean up unnecessary app locator privileges. Many small games, wallpaper tools, calculator-type aps are to be located without any reasonable use of the scene, with direct denial of access and less unnecessary data collection。
Many readers wonder if closing these permissions will affect the cell phone infrastructure? It can be made clear that the reasonable closure of excess privileges does not affect calls, text messages, scans, payment for these core functions. It's just those apps that rely on location for advertising, and they can't get your location, without compromising the normal use of core software services. For example, after closing off the positioning software, it is still possible to manually fill out the receipt address list without any effect。
There's also a common error zone: a cell phone flight mode is activated and the location is disabled. The mode of flight will shut down the cellular network and wifi, but many mobile phones with gps chips will still work under flight mode and will still be available for location. Access to priority control areas, with only insufficient flight patterns, requires manual closure of location services。
It is not accurate to say on the internet that mobile phones can be located even if they are off the grid. After the handheld, the processor and the locator chip ceased to work and it was not possible to proactively send location data out. However, if the cell phone is only locked and left unconnected, the backstage app can still be read with access. Distinguishing between shut-down and lock-on, do not confuse。
The offshore intelligence agencies collect location information that does not generally directly target ordinary people, more so through large-scale collections of user data through a large-scale app, followed by aggregated analysis through large data technology. When a large number of people travel in and out of a particular area frequently over the same period of time, the mass location data are superseded, and the pattern of human activity, time spent and movement within the region is analysed. Many people feel that they are ordinary citizens and that they are far from national security, that national security is not the sole responsibility of the staff involved in a secret post, and that the usage of mobile phones by every ordinary person is linked to national security。
National security is not a sloganCellular permissionsTo manage such small things. Many of the leaks are not due to complex hacker attacks, but to the user's consent to the authorization, the long-term opening of unnecessary privileges and a small amount of disclosure of personal tracks and environmental information。
In addition to access, there are a number of cell phone privileges that you are advised to check the clean-up and prevent the disclosure of information. The first is microphone access. Many small crowds of apps, such as wallpapers, clocks and so forth, require microphone privileges, and such software is completely off without recording. Some of the software will be recorded backstage to collect environmental sound information. The second is camera privileges, which are only allowed for scans, photo software, and the rest is banned. The third is address access, which prevents contact information from being collected by not simply giving access to small games, information apps。
You can take your cell phones out, take a few minutes, step by step and check your rights. The first step is to open the cell phone settings and find privacy or privacy and security plates. Step 2, find position information and see the list of all applications. The third step is to look at the position authorization status of each ap and replace the software permissions that do not require positioning with the denial; the software that requires positioning is set to allow for the duration of the application and to cancel the permission. Step four, access camera, microphone access page, mass cleanup without necessary authorization. Step five, open the camera settings, close the photo geographic tab. Step six, look at position usage records, keep an eye on strange software backstage calls, and find unusual and timely unloading of software。
It is recommended that you develop a habit of periodically checking cell phone access, which is cleared every two or three months. Following an update of the mobile phone system, it is possible to reset some of the privileges, to apply for new privileges when the new version of the app is being updated, and to do not accept the permission to pop out of the window with a sense of direct consent, wondering if there is any need for the software to access it. If you encounter an app whose reasons for requesting permission are unreasonable, try not to install it。
In addition, downloading software must be downloaded from the official mobile phone application store and the apk installation package should not be installed from web links, alien 2d codes, web links. Installation packages in unofficial channels may be implanted into malicious codes, private access to various kinds of privileges and collection of all kinds of information within mobile phones, which are highly hidden and difficult for ordinary users to detect。
Many people would think that managing cell phone access is a little trouble and not worth the time. But safety protection in itself is a small thing. A randomly authorized locational authority, with its accumulated strength, creates a complete personal movement trajectory. The national security service has repeatedly warned that there is a need to be vigilant and not to ignore potential risks because of simplicity. We do not have to panic, we do not have to give up the conveniences of smartphones, we simply have to learn to fine-tune the competencies, open them as needed, shut them down, and balance easy access and information security。
The security of personal information is closely linked to national security, of which everyone is a participant and guardian. Having a good cell phone usage, controlling cell phone access, refusing to collect unnecessary information, is protecting themselvesPrivacyIt is also in the interests of national security。
