about spam

2010-07-19T12:12:00.000-07:00

hey today i am saying something about "Spam" its one of the irritating experience for email users

What is ‘spam’?

Spam is the abuse of electronic messaging systems to indiscriminately send unsolicited bulk messages, that is unwanted by the recipient.

unsolicited commercial electronic messages includes email, sms, MMS, calling machines, faxes, IM.

The People who create electronic spam are called Spammers.

History of Spam.

It is widely believed the term spam is derived from the 1970 SPAM sketch of the BBC television comedy series " Monty Python's Flying Circus " .The earliest documented spam was a message advertising the availability of a new model of Digital Equipment Corporation computers sent to 393 recipients on ARPANET in 1978, by Gary Thuerk.

Costs of spam_.

The European Union's Internal Market Commission estimated in 2001 that "junk e-mail" cost Internet users €10 billion per year worldwide.In 2007 spam costs more than $13 billian in US only including lost productivity and the additional equipment, software, and manpower needed to combat the problem.Many also find the content of spam frequently offensive, in that pornography is one of the most frequently advertised products. Recently, there has been a noticeable increase in spam advertising websites that contain child pornography.

The secondary consequence of spamming is that search engine indexes are inundated with useless pages, increasing the cost of each processed query. Spam can be used to spread computer viruses, trojan horses or other malicious software. The objective may be identity theft.

How do Spammers operates.

The whole process of working of spam can be described in two phases:

(1) Gathering of addressing: the first job of spammer is to gather email addresses.But: 'how did we loose our email address'

Somebody send your email address using either the “To” or “Cc” field.once the computer of a person with your email address in a addressbook with your email address in an received email is infected with an harvesting virus,your email address is known to spammers.

Using automated program:spammer search the internet (WWW,FTP,Newsgroup) to try to find as many email address as possible.

Dictionary attack:- Spammer don't know your email address but try all words in dictionary.

(2) Delivering Spam message: A comman practice of spammmer is to create account on free webmail services(i.e.-Hotmail) to send spam or to receive email responces from potential customers. Because of ammount of mail sent by spammer, they require several email accounts and web-bots to automate the creation of these accounts.

_{How to deal with SPAM:}

The following techniques are described below to deal with Spam. Software to handle Spam:

(1) Check directly build into the MTA(Message Transfer Agent = Mail Server). Here we can usually reject the mail. i.e. We don't even store the email. We send an error code back as soon as we recognize that this is spam during reception of the email.

(2) Filtreing after the reception of mail - In this case the email is successfully delivered and mail will be filtered out later.

(3) Captcha : In an effort to cut down this abuse many of these services adopted a system called the Captcha. User attempting to create a new account are presented with a graphic of word.Which uses a strange font on a difficult to read background. Humans are able to read these graphics and required to enter the word to complete the application for a new account.While computers are unable to get accurate reading of the words using standard OCR (Optical character recognition) technique.

_{10 Tips to Reduce or Stop Spam. :}

1. Use a separate email address.

2. Consider acquiring multiple email addresses for different

purposes.

3. You can subscribe to online services to stop spam.

4 . Remove your email address from your website.

5.NEVER buy anything from a company that spams

6. Filter your email .

7.Make proper use of bcc & cc,To,to header files.

8.Don't display images in your email client.

9.Don't click on links in Spam message.

10. Don't install unkonwn “.exe” file.

steganography techniques

2010-07-09T09:10:00.000-07:00

Here i present some important point regards Steganography and its techniques

What is Steganography?

Steganography is the science and art of hiding data in communication.

In the olden days , people used invisible ink and hidden tattoos to pass hidden Steganographic content. Now a days, computer and network technologies give us easy-to-use communication channels for Steganography.

Difference Between Steganography and Other technologies

Steganography & Cryptography

Steganography and Cryptography are two distinct techniques, however, they can be used together to add an extra layer of security.

Basically, Steganography techniques conceal the existence of hidden messages, while cryptography techniques don’t.

Steganography & watermarking

Watermarking allows us to prevent infringers from stealing our document rights.

Watermarks are explicit; everyone can see them.

Steganography is used to protect papers’ copy rights without watermarking.

Major Techniques Used in Steganography is

1.Word shifting.

2.Line shifting.

3.Feature coding
And There are two major word shifting techniques
1. Shifting spaces.
2.Shifting specific words
1.Shifting spaces

Shifting a word by one point represents a “0”, while shifting it by two points represents a “1”

Example:

We want to hide : “0110110” in :

We explore new steganographic and cryptographic algorithms and techniques throughout the world to produce wide variety and security in the electronic web called the Internet.
2.Shifting specific words

The words we want to stress out are shifted by one point, that is expanding the space before them and condensing the space after them by one point.

Example:

We explore new steganographic and cryptographic algorithms and techniques throughout the world to produce wide variety and security in the electronic web called the Internet.

virtual reality

2010-07-09T08:26:00.000-07:00

here i can make a tutorial that how to make a virtual reality seminar as a techee

These are the main streams in virtual reality presentation

What is virtual reality ?
Tools and applications we use in virtual reality
Development approach
Task and requirements analysis for virtual environment
Task and domain models
Case study example
Virtual environment design

If some one ask you What is virtual reality ? then the answer is

virtual reality (VR) is a hypothetical three dimensional visual world created by a computer .here User wears special goggles and fiber optic gloves ,and he can enter and move about in this world (virtually ) and interact with objects as if inside it

And tell me Applications of virtual reality

virtual reality(VR) has survived and found use in several domains

For examples :

Education and training
Entertainment and fun
Discovery of planets
Meeting

How to Develop virtual reality in real world

Designing virtual worlds is in many ways similar to designing any HCI.
Virtual worlds are intended to mimic the real world .
Sometimes we find the real world very confusing and unusable, so transform it into virtual world just transfer the confusion.
VR design has to be carried out within the constraints of available technology

simply the design steps of Virtual reality is:

1* create the background for the virtual world.

2*design interactive objects, agents structures.

3*add navigation way marks and pathways.

4*plan integration of the VE with the whole U
