Shoulder surfing

Posted: July 20, 2010 in Uncategorized

Hi friends…! After a day break with stress in college happy to catch you back and now jumping directly to the info….

Seems to be a bit enthusiastic today after getting a 100 rupiya from CEO of Dhyan infotech during an interactive session while attending a techtalk.

Shoulder surfing, This is quite funnier to hear and its meaning directly makes a meaning as hanging onto someone’s shoulders and browse. Its actual meaning does the same but in different view for that better take an example,

with respect to your home, a family member may be curious to see what information you have stored on the computer. A member of the family may also be nosy and want to know the user names or passwords to websites or accounts you might access via the Internet. In the comfort of your own home you may be less likely to think that one of your family members may be a shoulder surfer; however, it may very well be the case.

At your place of employment you might even be at risk. Co-workers might be curious as to the activities you engage in on your computer. If their jobs require that they do different tasks then you, they may want to learn how you do your job. They may want to look at the programs you utilize to perform your job. Even worse, they may want to check your e-mail accounts. These are all possible motives of the shoulder surfer who may just be around the corner near all the walls.

So just be aware about your surroundings before get down to any job……

The most enthralling lines i got remind always is ” Desire, Ignorance & Inequality were Trinity of bondage”

Please dont misbehave orelse dont let misbehaviour.

Hi friends…!!! after pretty long back  now to make a little touch with technotweet. Yupp!!! let us see about the most credential aspect  called  “CAPTCHA”. This is the one you find during the user side verification code and you will be typing the text in an enumerated like form on a specified section.

Okay, we will discuss about types of CAPTCHA and its necessity below

Basically CAPTCHA’s are divided into 3 types Early, Improved, Modern.

Whereas Modern CAPTCHA’s include following types,

• Animated CAPTCHAs

• 3D CAPTCHA

• ASCII art

A good example for this is movie like  Transformers 1.. a mini bot on an aircraft will be stealing the data about the mission and secret base very easily which a human cant do such faster.

CAPTCHA is quite commonly necessary to stop BOT’s intrusion moreover computer access to the human prior sites. As per security analysis it is must because as said previously to stop the BOT’s intrusion on some high defined logical reasoning access which would take more time for an unauthorized user the BOT’s makes them easier.
