How to hide files inside an image in your android phone??

Hey guys, today we will be showing you the way you can hide your confidential data inside an image file so that, no one can see even one gets the file, one will see simply that image file only not the data inside that image file. We will use a command line tool for this and will pass on some commands to bind the data inside the image and later to unbind them.
So, name of the software is "TERMINAL EMULATOR" which i guess a few mb apk file which you can easily download from play store. So, go to play store ans search for it and install it. Don't worry, it is not required to root your android phone for this. So, root access is not necessary.

As you can see, i have already installed it in my android phone. So, it's giving me open option.
So, we assume you have installed that apk file and ready to go with it. In this tutorial we are having two files first a image file with name "img.jpg" and then move all your confidential files inside a new folder with name say secret and then make a zip file of that folder so that now we are having secret.zip file with all the confidential files inside it.

Let me show you the size of both files i.e secret folder and img.jpg first.

 

So, you can see that size of img.jpg is 417 KB and that of secret.zip is 1.45 MB.

Now time to go with terminal emulator.
Before that first delete secret folder cause you have already made a zip of that folder so, you no longer going to need it.
Now follow the steps....
1) Fired up terminal emulator.
2) Navigate to the path where you have placed those image and zip file. Well, in our case, we have moved them inside phone directory. So, redirect your terminal to that location by giving the command as
"cd storage/sdcard0" (Without  quotation mark of course and hit enter)

3) Then give the cat command to bind the zip file inside the image file.
"cat img.jpg secret.zip > img.jpg"  (hit enter)

 

4) That's it. Now feel free to delete the secret.zip file cause we are already having that file inside the img.jpg file. Let me show you the new size of img.jpg to give you proof which should be equal to size of secret.zip file i.e 1.45 MB.

5) That's it. Now no one is gonna see that zip file ever. If you wanna see it for later then again open terminal and use unzip command to unzip secret.zip file from img.jpg. So, command would be simply
"unzip img.jpg" (hit enter)

That's it. Now open phone directory, you wll find your secret.zip file back again there.
So, guys i guess now you can hide files inside an image file in your android phone. That's it for now, we will see you soon with another tips and tricks.

Why we face signal issue while travelling??

Hey guys, today we will take you to an incident that we almost face in our daily life i.e when we travel in train or any vehicles then we see that signal of our phone fluctuates and some times it goes off completely and also call goes drop. So, why this happens. Here is the thing that one should know while travelling and bothering about the signal.

A signal is something that we use to transmit and receive the information with our nearest BTS(Base Transceiver Station or simply Cell Tower). Well, we are not going to much deeper with engineering terms. I will keep this simple. So, until and unless, you switch off or turn your phone on flight mode, the flow and hence fluctuation of signal will keep on going. So, if you wanna save your battery while travelling and you have nothing to do with your phone then better to go for flight mode or turn off your cell phone.

Fluctuation of signal of your phone is due to fact that your phone is connecting to new bts(cell tower) and also it goes away from connected tower due to you are in motion while traveling. So, Hand off is a process through which our phone switches to different bts i.e one to another and so on. Hence, we face signal issue while traveling. If time to switch between one bts to another will be more then if we are in call then our call goes drop or disconnect and we also face this problem while traveling.
But, if are in stationary and thus connected to a single bts due to the fact that we are not in motion, so time upto which our call maintains within a single bts without any hand off is called DWELL TIME.

So, we hope now you guys are aware of the facts that we face with the network of our phone while travelling in any vehicles. So, that's it for today we will see you soon.

How to detect camera in a changing or trial room

Welcome you all to my new post. Today, we will give you some tips to detect a hidden camera in a changing room or anywhere else.
We all like to shop in mall and buy our favourite clothes and also we get inside the changing room of that mall to check the fitting of our selected clothes. But, sometimes we hear the news that a particular shopping mall had a camera and it got banned by the police but till then it becomes so late that we would had nothing to do. Mainly, girls are made victims of these craps. So, this post is mainly for all the women out there.
So, follow these steps.

1)Use your eyes: This is the normal way to navigate the whole room where you are in. Just roll your eyes around and find whether or not camera is present in the room.

2)A small practical with mirror in the room: Every trial room has a mirror ofcourse.So, all you have to do is just touch your finger with the mirror then ofcourse a image of your own finger will be formed in the mirror too. So, if there is a distance in between both i.e between your finger which you have touched with the mirror and the image of your finger formed inside the mirror, then that means it is a true mirror but if, there is no any gap or distance in between them then that means, it is a two sided glass or mirror not a real mirror. A two sided glass or mirror is one which will look like a mirror when you see it from one side but when you will see it from other side the it will be transparent i.e, anybody can see you from other side of the mirror and you won't have a micro doubt even.

 

3)Check your mobile network: We know technology has been still growing and today size of electronic gadgets are decreasing and thus increasing their speed of performance with less power consumption. So, modern camera is smaller in size and that also means it's bandwidth will be higher in order to record high defination video and as it has higher bandwidth thus it uses optical fiber cable for this purpose. So, all you have to do is just open internet connection and try to access any random web pages on your mobile browser, you will see that pages are not accessible properly also try to make a call to anyone you will also see that calls are not placing properly, then maximum chances are to have camera in that trial room.

So, if you face any doubt after doing above experiments then better to not use that trial room or any room.
So, guys that's all for now, we will be back with some other chapters of technology.

Web family types & details

Hey guys, what's going on. Well, today we are gonna describe the types of web pages present on the internet. Namely, there are three types of web pages present on the internet which are
1) Surface Web
2)Deep Web
3)Dark Web
So, let's learn what are these. So, start from the first one and then will move to the last.
1)Surface Web: These are the normal web pages that we surf, download, upload on the internet. For example if we type some query in the google search box like "Who was the inventor of Internet" so, whatever pages that we get after pressing enter are called Surface web. In short way whatever pages that we visit on internet without any authorization are called surface web.

2)Deep Web: These are the pages which are not indexed by google search engine. For example, suppose we create our own website for our organization which contains many web pages but there are some web pages which we don't want any people other then a selected group of that organization or a registered users to access. So, if someone wants access those pages then first he/she has to authenticate him/her self then only one can access those pages. On the internet , deep web has a very large area which are not for public access. Whatever secret plans of government would be those are saved inside the deep web so that no one can access those pages for security purpose without having username and password. There are many things beyond the scope of our thinking which have been hidden inside the deep web.

 

3) Dark Web: These are the most dangerous part of the internet world. These pages are for only illegal usage like smuggling , gambling and some other crimes. These pages are used to sell all the illegal things on the internet which we can not tell even. So, close your eyes and think whatever illegal things that you can think in your mind, are sold on the dark web.These are hidden inside deep down to the internet's layer and obviously are not indexed in the search engine's dictionary. 98% users of the internet don't know about these pages. They are only known to users who involves in illegal activities.

 

So,  guys we think now you have a complete idea about surface, deep and dark web. We are signing out for now and will fetch you with some another technical solution.

Windows registry and all that you need to know about it

Windows registry is simply a database which contains all the setting of our windows file and installed third party software. The Windows registry is divided into several root keys. They can also be called Hives. Registry keys are similar to folders.Five hives are HKEY_CLASSES_ROOT, HKEY_LOCAL_MACHINE, HKEY_USERS, HKEY_CURRENT_CONFIG, HKEY_CURRENT_USER and sub keys.

Registry key has sub keys which contains value in string, binary, hexadecimal, Dword, QWord
 forms.

Registry contains some value. So, suppose you have a software of file conversion like pdf to doc or pdf to excel. So, you open the software and customize it's setting according to your need and save the setting so that, you don't have to change the setting again. So, this setting is stored in windows registry. Windows registry also stores all the setting of your windows. Your windows is itself a software whose settings are stored in registry.
So, when you save some settings of windows like enabling or disabling hidden files or folders, hide or show extension for the files, hide or show the system files, some network settings so, all the settings are stored inside the registry. So, that it would be easy for you and you don't have to bother for changing and saving the changed setting again again.
Windows registry was first used in windows 3.1 version and then it is being used till now.
But is it necessary that every softwares save it's setting in the registry??
So, it's not like that. There is no rule that a software must save it's setting inside the registry. Some saftwares come with its own xml file which contains setting of that software both default as well as user's customize settings. So, that when we open that software then the software first reads that xml file and check the last customize settings of user's and then open the software with those settings and same thing happens if a software saves it's setting in windows registry i.e software first checks it's setting from registry and then open up with those settings.
You may find some registry editor softwares which manipulates the value stores in the registry and thus changes the setting but it's a very risky to messing up with registry until and unless you do have the proper knowledge of it.
