TOP SECRET
Until recent times, secret codes usually involved governments, ambassadors, spies, and the military. But not anymore. With the advent of computers and the Internet, valuable data are often kept secret by a number of elements, including passwords, which are authenticated every time users access their records. Indeed, never before has secrecy played such a big role in everyday life.
But, is logical that we ask: How safe is my confidential data? Can I do more to heighten security?
Secret Scripts
The objective of steganography is to hide the very existence of the message.
Modern forms of steganography include using the microdot and watermarking paper and images for copyright protection. Today, people who peddle illegal pornography employ a similar concept. Aided by computer software, they hide pictures in otherwise innocuous digital images, text, or sound files.
Because the existence of the message itself is kept secret, steganography does not draw attention to either the carrier or the recipient. On the other hand, if the message is discovered, it can be read—unless it has also been encrypted.
Hiding the Meaning
Cryptology, or hidden word, is the science of keeping communications confidential by concealing, not the fact of the message, but its meaning. The process involves scrambling and unscrambling data according to a predetermined system of rules, thus only those parties who have the key are enabled to decrypt the message.
The European Renaissance provided the means for more sophisticated advances in cryptography.
By the 15th century, cryptography was becoming a routine tool of European diplomats. But it did not always guarantee security.
Technology Enters the Fray
In today’s digital world, banking, money transfers, and payments as well as medical, corporate, and government records are secured by means of complex encryptions. The cipher text, in turn, is read by those who have the necessary decryption key to restore the data to its original form.
A digital key is a string of zeros and ones in various combinations. Longer keys have more combinations and are thus harder to crack. The present standard for encrypted Web browsing is 128-bit keys, which have 4.7 sextillion times more permutations than 56-bit keys!
Still, security breaches do occur. In 2008, for instance, federal prosecutors in the United States charged 11 men with what is thought to be the largest-ever case of identity theft. The group allegedly used laptop computers, wireless technology, and special software to capture numbers from credit cards and debit cards used for payment at cash registers.
Is Your Confidential Data Safe?
To be sure, the encryptions protecting your bank accounts and online transactions are extremely hard to crack. Yet, much also depends on you. So be shrewd and “conceal” yourself, as it were, from fraud and theft by doing at least the following:
- Use antivirus software on your computer.
- Employ a spyware-detection program.
- Install a firewall.
- Keep all of the above continually updated, and install security updates for your applications and operating system.
- Beware of links or attachments in e-mail or instant messages, especially if the mail is unsolicited and asks for personal information or for verification of a password.
- When transmitting sensitive data, such as credit card details, use encrypted connections, and log off the Web site when you have finished.%
- Choose passwords that are hard to guess, and protect them.
- Do not copy or run software from unknown sources.
- Regularly back up your files, and safely store the copies.
- If you follow those basic precautions and apply any others that may be advisable now and in the future, you at least improve your chances of winning your own battle for confidentiality and security.

Australia
GEOGRAPHY
The continent of Australia is equal in area to the US.
The western half of the continent is occupied by a desert plateau.
The desert plateau rises into barren, rolling hills near the west coast.
The Great Barrier Reef, extending about 2,000 km
The Great Barrier Reef lies along the northeast coast.
The island of Tasmania 67,800 km is off the southeast coast.
GOVERNMENT
The system is governed by the Democracy .
Symbolic executive power is vested in the British monarch.
The British monarch is Elisabeth II.
The British monarch is represented throughout Australia by the governor-general.
HISTORY
The first inhabitants of Australia were the aborigines.
Today about 350,000 Aborigines live in Australia.
Dutch, Portuguese and Spanish ships sighted Australia in the 17th century.
Six colonies: New South Wales, Tasmania, Western Australia, South Australia, Victoria and Queensland.
Several gold rush attracted settlers, as well as the extraction of other minerals.
The six colonies became federated states and established CONSTITUTION (1901).
Australia became known for its liberal legislation: free education, the secret ballot, women's suffrage…
The most populous and vital Australian cities include: Sydney, Melbourne, Brisbane, Perth, Adelaide
AUSTRALIAN CLIMATE
The climate of Australia includes all the climatic stations and meet all the host-seeking in different areas.
There are deserts, savannas, forests, valleys, arid and humid ...
LANGUAGE IN-USE AT AUSTRALIA
Australia aborigines speak in English but not in a typical traditional way.
The colloquial Australian-English uses abbreviations like:
- Aussie for Australian
- Brolly for umbrella
- Chook for chicken
- Damper for bread,
- Ta for thank you and so on.
AUSTRALIAN CURRENCY
Australian dollar called AUD is the currency in this country.
Australia is a great tourist destination to visit and enjoy your holiday.
WILDLIFE
There are about 280 species of mammals, 800 birds, 300 lizards, 140 of the snake and two crocodiles.
In mammals, almost half are marsupials.
The best known animals are the kangaroo, koala, platypus, koala and the spiny anteater.
The isolation allowed the Australian continent to become a sanctuary for marsupials -mammals that nurse their young in pouches.
Australia has 20,000 species of plants such as cycads and palm grass, wildflowers and bright as the Waratah, Sturt's Desert Pea, flower cones of Banksia trees and the red kangaroo paw and green.
The continent has 700 species of acacia, and 1,200 species of the family Myrtaceae, including Eucalyptus trees or gums.
Some species of embracing the land as bonsai, while others go to heaven and samples of more than 45,72 m have been recorded.
MY OPINION
Iban, pep and I Hempseed done a good oral presentation, for few of time can't be, but even so we did pretty well.
I have to improve in the expression, it's difficult to do well because English isn't my native language.

The second earthquake in haiti.
A second strong earthquake hit Haiti today, waking people from their beds and sending others running into the streets in panic.
The quake measured 6.1, and hit a country already ravaged by an earthquake eight days ago.
It came amid rising frustration from one aid agency about the delay in getting lifesaving supplies into Haiti, with doctors saying they are having to buy their own saws to carry out amputations.
The quake was centred 26 miles north-west of Jacmel, and the US Geological Survey said it struck at a depth of 13.7 miles.
The tremor caused panic. It was not immediately possible to assess what additional damage the new quake may have caused.
Last week's huge quake killed an estimated 200,000 people in Haiti, left 250,000 injured and made 1.5 million people homeless. A big international aid effort has been launched, but is struggling with overwhelming logistical problems.
That everything is solved and that very soon they are better. Mood ...
