How to Send a Secret Message

Introduction

The term Steganography as well cryptography was derived from the Greek language. Cryptography is essentially the art of secret writing and the goal is to maintain the secrecy of the message even if it is visible. Steganography, means covered writing, and is a long-practiced form of hiding information. It should not be seen as a replacement for cryptography but rather as a complement to it.

Cryptography is used to conceal the content of a message, while steganography is used to conceal the existence of a message.

The technology behind effective Steganography is quite complex and involves serious mathematical computations. Computers and technology make this an easy task and make this art of deception a serious threat to the security of

information. The strength of a steganographic algorithm depends on its ability to successfully withstand attacks. Companies with important and sensitive information, and relying on the security and integrity of their intellectual property, could be at significant risk.

Steganography under various media

Steganography includes a vast array of techniques for hiding messages in a variety of media. Among these methods are invisible inks, covert channels, digital signatures, microdots, and spread-spectrum communications. New age technology helps steganography to use various mediums like – text, images, sound, signals, and more.

Steganography in Text

This process involves using steganography within text, i.e. documents or emails. This process is used to counteract the wide scale piracy or illegal distribution of documents, wherein infringers make identical copies of documents without paying royalties to the original author.

  1. Line-Shift coding: In this method, text lines are vertically shifted to encode the document uniquely.
  2. Word-Shift coding: In this method, codewords are coded into a document by shifting the horizontal locations of words within text lines, while maintaining a natural spacing appearance.
  3. Feature coding: In feature coding, certain text features are altered, or not altered, depending on the codeword. For example, one could encode bits into text by extending or shortening the vertical end lines of letters such as p, q, y, etc.

Steganography in Images

This process involves exploiting the Human Visual System (HVS). Image steganography is being increasingly used due to the development of powerful graphical computers and the increasing softwares over the internet.

  1. Image Compression: Image compression helps in reducing the file size by compressing it to a certain extent. Two kinds of image compression are lossless and lossy compression.
  2. Image Encoding techniques: This technique involves in hiding the secret information within the image. It can be done in many ways, like encoding every bit of information in the image or encoding only in the noisy areas of the image.

Steganography in Audio

This form of steganography is very sensitive to handle, as it involves exploiting the Human Auditory System (HAS). We call it sensitive, because the HAS posses a large dynamic range but a small differential range. The following are the methods of this type of steganography –

  1. Phase Coding – This process involves substituting the phase of an initial audio segment with a reference phase that represents the data.
  2. Low bit encoding – This process is similar to image encoding, wherein binary data is stored in the audio files.
  3. Spread Spectrum – In this process, the encoded data is spread across the frequency of the audio data.
  4. Echo Data Hiding – Echo data hiding embeds data into a host signal by introducing an echo.

Conclusion

There are so many components to this form of deception, which are increasingly used either for safeguarding some valuable data or for destroying it. The thing with white collar crimes is that criminals don’t necessarily “look” like criminals and they often proceed for years without being caught. This article aims to make people aware of this form of deception and the threat it poses to digital security.

Life is Unpredictable, Your Data Shouldn’t Be!

With the arrival of various internet based applications which allow people to express themselves, the web has definitely become democratic. But using the same for carrying out personal or malicious activities, and that too using your office computer can land you in deep trouble.

A senior executive at a marketing firm was accused by his boss of passing on vital company data to a competing firm, he denied it. “But we have the proof”, his boss told him and showed it to him, as clear as daylight. The executive resigned immediately. It’s a fact of life in the 21st century workplace; the boss may well be watching you, especially if you use a office computer. Improper computer use can also spell legal trouble. Downloading pirated music or movies onto a work computer can prompt a copyright-infringement suit. Viewing pornography or sending sexually suggestive emails can lead to sexual harassment claims. Thus, an employer can use special software to monitor everything – it’s as if a camera is watching your computer.

Companies are using two types of spying software: network-based programs that monitor all traffic passing through a system, and programs that sit directly on an employee’s desktop. What can such software do? They can track and block the websites a user tries to visit and log his or her every keystroke. The boss can see screen shots of what the employees do on Yahoo! He can see what they’re typing, whether it’s resumes or business-related stuff. Such program even keeps track of songs that employees download to their iPod. In the American and European countries, one in four companies reports firing someone for improper email use. Such software works without being identified, even by an anti-virus program.

There are plenty of valid reasons for companies to monitor their worker’s computer use.

1. Productivity: A recent survey found that employees on average wasted at least two hours a day-much of it online-doing things other than work.

2. Security: Porn, gambling and gaming sites, for example, can harbour viruses and other malicious programs that load onto a computer secretly and allow outsiders to damage a network or make off with sensitive information.

3. Companies also have competitive reasons to keep tabs on workers.

4. Employee attrition: With young employees who may have quickly changing loyalties, more and more companies see the need to spy.

5. Reputation Management: Companies want to be sure that there employee’s defamatory work does not harm the company’s global reputation.

Implementing all these policies may be beneficial for the companies, but the employees always feel pressurised. They feel paralysed, if their every activity from composing the weekly report to emails is tracked. And who hasn’t opened his email to find a message from a friend passing along a goofy YouTube clip or an off-colour joke. If it does get a laugh, it’s probably passed along to a few more people. And this can seriously land the employee who first circulated such content within the company.

It seems that technology will continue to creep unabashedly into the workplace. So, if you blog, forward naughty email, flirt, chat or search for a new job, just remember that it’s safest to use your own computer for any of that in the comfort of your home.

Quick Diagnosis of a Dead Laptop LCD Display

If you own a laptop computer, sooner or later you are going to be faced with a computer that has a display that has gone dark typically in one of two scenarios. In the most common case the LCD screen is damaged because of some physical event that caused the screen to be cracked or broken. Laptops do not take kindly to being dropped, especially when the case is opened and the accident occurs. In the second case there no physical damage and a malfunction in the video,power or control circuitry has caused the display to malfunction.

In the case of the cracked or physically damaged screen you need to determine if there is other damage to the laptop. The best way to do this is to plug in an external monitor using the video output connector at the rear of the laptop case. If the external monitor works and you see that your applications function then you know that you are looking at a LCD screen repair, and in the event you don’t repair the laptop you can still recover your data. Even if you elect not to repair the laptop this kind of failure is the best of a bad situation because the laptops still functions and you can still recover your data.

If the Laptop screen hasn’t been physically damaged, but the screen is still blank, you should still connect an external monitor as described above and determine if the rest of the laptop is functional. In the case where the screen is blank and an external monitor doesn’t work a more expensive diagnosis and repair scenario will probably be your only option.

It is always best to take these basic steps before you get a repair person involved. You should think through your repair options before you are confronted with a potentially costly repair decision.
