Beware of Hardware Key-logger in Public computer like Cybercafe

Most of time we have heard about software key logger. This software key-logger activates once Operating system starts but here is Hardware key-logger it will log every key stroke from the moment computer is turned on.Typically the memory capacity of a hardware keylogger may range from a few kilobytes to several gigabytes, with each keystroke recorded typically consuming a byte of memory. So beware of such device in public system before using sensitive data and secure web-pages like Internet banking. Here is types of Hardware key-logger.The first one is very simple it can be used with keyboard port very easily.

 
1. A Regular Hardware Keylogger is used for keystroke logging by means of a hardware circuit that is attached somewhere in between the computer keyboard and the computer. It logs all keyboard activity to its internal memory which can be accessed by typing in a series of pre-defined characters. A hardware keylogger has an advantage over a software solution; because it is not dependent on the computer’s operating system it will not interfere with any program running on the target machine and hence cannot be detected by any software. They are typically designed to have an innocuous appearance that blends in with the rest of the cabling or hardware, such as appearing to be an EMC Balun. They can also be installed inside a keyboard itself (as a circuit attachment or modification), or the keyboard could be manufactured with this “feature”. They are designed to work with legacy PS/2 keyboards, or more recently, with USB keyboards. Some variants, known as wireless hardware keyloggers, have the ability to be controlled and monitored remotely by means of a wirelesscommmunication standard. 
2. Wireless Keylogger sniffers – Collect packets of data being transferred from a wireless keyboard and its receiver and then attempt to crack the encryption key being used to secure wireless communications between the two devices.
3. Firmware – A computer’s BIOS, which is typically responsible for handling keyboard events, can be reprogrammed so that it records keystrokes as it processes them.
4. Keyboard overlays – a bogus keypad is placed over the real one so that any keys pressed are registered by both the eavesdropping device as well as the legitimate one that the customer is using.^[

New Revolution in USB Technology : USB 3.0 ,Diffrence between USB2.0 and USB 3.0

 
USB  is most innovated ideas which causes revolution in field of computers,currently USB 2.0 is used in most of the computers which leads to a very high data transfer as compared to the older ones but now USB 3.0 is launched , next generation USB. USB 3.0 much faster and safe as compared to USB 2.0
New USB 3.0 products are 10 times  faster than USB 2.0 means data transfer speed upto 5 GB/ sec
Faster power transfer (900 mA) in USB 3.0 as compared to USB 2.0 (just 500 mA) means increase in speed of scanning by USB scanner and other equipments.
It also means that LAN connection will be replaced by USB 3.0 as it is much faster than LAN.
But if you want actual speed of USB 3.0 than you have to use both USB 3.0 equipment  and USB 3.0 ports, as in USB 2.0 ports, the speed of USB 3.0 equipments decreases and it will be same as USB 2.0 equipments or  you can use the USB card adaptors as shown above.

USB 3.0 is a great improvement to USB 2.0. The biggest difference is the speed at which it can communicate with computer’s . USB 2 had a maximum speed of 480 Mbps, which was very speedy at its time but now it might not be enough because we now have USB flashdisk drives which are 64 GB in size, cell phone and PDAs that have a lot of internal storage built in, and even at 480 Mbps a full transfer of data in between devices can take a long time. So now USB 3.0 has a speed of 4.8 Gbps, almost 10 times faster than USB 2.0. Now if we want to transfer files from a pc to a 64 Gigabyte flashdisk to full capacity, we can do it in under 20 minutes!!

>Sakshat Tablet to be Launched in June 2011-Laptop in just Rs 1500

>

Remember the Rs. 1500 Indian laptop? The one that got the world making fun of India in general and me never having faith in Kapil Sibal again?
The one that actually turned out to be an expensive storage device, and then somehow metamorphosed into a tablet?
It’s being announced that the “Sakshat” (which sounds conspicuously dirty in Americanese), the $35 tablet codenamed ‘Sakshat’ is expected to launch by the end of this month.

While the Indian media is huffing up the desi-pride angle with talks of “Indian-iPad“. there’s very little for a complete tablet experience. And there’s nothing desi about it; the tablet is made by Canadian firm Datawind Ltd.
The7-inch touchscreen tablet features a inbuilt keyboard, video conferencing facility, multimedia content, Wi-Fi, USB port, 32GB hard drive and a 2GB RAM. There’s support for Open Office, SciLab and Internet browsing.

However, this means nothing for the aam-aadmi it was intended for, but there is a desi crop of real tablets worth checking out.
10,000 Sakshat tablets will be shipped to IIT Rajasthan by June-end, following by the launch of over 90,000 tablet units in the next 4 months.

Sakshat: Other Specifications

QWERTY keyboard, mouse and a minimum display of 7” colour LCD/TFT (touchscreen optional)
2 USB 2.0 ports and USB hosts
three hours
batteryless device
SD card slot (8GB expandable memory)
Support to connect LCD projector
Support for external hard disk drive (Minimum 32 GB)
Ethernet port
WLAN
80% shock resistant

While the tablets will be priced at Rs 2,200, there are reports of plans for later subsidies of 50%. The 1500 Rupee tablet might go for Rs. 1100, and has been developed as a part of the National Mission on Education through Information and Communication Technology to bring together 25,000 colleges and 400 universities in the Asian subcontinent in an e-learning initiative.
