What are applications of cryptography?
Cryptography is used for securing transmission of messages, protection of data, and to provide privacy and security in any situation where information is not intended for public consumption. Examples include political campaign plans, extramarital affairs, coverups, ecommerce, business transactions, and private communications.
Can you find out what websites you go on even if you delete your history?
you can down load software from my website...
Is there any internet scams going on in and around osun that the local authorities know of?
There are shopping website scams. Unfortunately nobody seems interested in doing anything. For example, eBay allows scammers to exploit their system to fish for potential victims. MSN allows scammers to use their MSN and email to communicate with potential victims.
These companies don't respond to complaints.

What are the Benefits of Cryptography in computer Security?
Without going into the fact the Cryptography has been used in some form or another for many hundreds, if not thousands of years, it's benefits when it comes to computers really come into their own. I will give some examples.
Cryptography allows us to hide information. Be it a letter, be it a file, be it a constant stream of video or audio over digital sources. Now computers are good at only one thing it's manipulating and processing truly staggering amounts of data and information of many kinds in a short period of time. Information that would take humans to work though many, many times longer.
There for the basis of breaking encryption becomes much easier with computers and logical/Turing machines which are constructed to apply mathematical force to a cytological methods until it finds the key. Normally it would take a bunch of people working on paper and pencil a insanely long time due to the complexity of modern cryto-methodology. So much so it's just not remotely feasible without some kind of computer. In fact, computer technology as we know it today is largely based on the work of men who created them as tools to, in fact, try and break codes during world war II.
So since computers make breaking codes much easier it therefore becomes necessary to use stronger and stronger methods of encryption and increasingly more complex keys. This has been a constant war for some time between those who built crypto-systems and those who break codes.
Since most of the data in the world these days flows over computers on either public or private network connection ranging from local to global it becomes necessary to have a strong, reliable encryption methods for your data because it's laughably easy for some one to just sniff packets off a network and read all the data you happen to be sending if it's not encrypted. So Crypto-systems are needed in order to maintain data secrecy (for Governments, Companies protecting intellectual property, individuals who seek private communication and yes, even criminals who seek to keep their data safe from the authorities) for the people in question.
The benefits could be compared to either pulling some one aside to speak to them privately (encrypted) or shouting the information across a crowded room (unencrypted). It all depends on your need for security and privacy.
This is a complex subject, but basically encrypting data if done correctly allows me to hide what I am saying to my friend/co-worker/boss from those I might not want to read my mail/conversations/files.
Hope that helps!
A possible consequence of oversharing online might be?
being incriminated against or fired by an employer.
Why hotspot shield is not working?
The hotspot shield may not be working because the mac address for the network interface may need to be updated or change. Another issue is that it may need to be uninstalled and then reinstalled back onto the computer.
Whatever you read in your mind it can understand to other people it can possible?
Maybe you should try phrasing the question like a person who understood even a shred of English would.
Passwords
Passwords are the easiest and most common authentication process that are used, not only on desktop computers but also at the network level. However certain rules should be followed when setting a password for your computer or Network. Do not use easily predictable words for your passwords; they don't even require a hacker to access the system through your account. Use passwords that are unpredictable. Set long passwords and use numbers and special characters when setting your password. Remember your passwords; don't write it down anywhere. Hackers use various tools to know your passwords, but a long password with a number of special characters, indeed gives them a lot of trouble.
Digital Certificates
Using a certain algorithm, computer administrator combine your personal details with other user credentials to generate a public key. This public key or digital certificate is used for the authentication purpose in the network.
Smart Cards
Smart Cards are among the very few hardware authentication processes in which a simple card with an embedded circuitry is used for accessing the network. Each valid card for a particular network, when inserted into the circuitry it has been made for, gives an output which decides whether you will be allowed to enter into the network or not. The programming logic inserted into each card is different and it is one of the safest methods of authentication.
Fingerprint detection
Almost available in all laptops that are manufactured today; fingerprint detection is another safe method of computer security authentication. Everyone knows that even the iris pattern of two people may even match, but fingerprints can never match.
Face recognition systems
Face recognition system, may amuse you, but of late many people working in the field of security have questioned its user friendly nature and the security it can provide. A simple dimension calculation of the face is done by the computer and the logic used in doing so, has been often found to be prone to errors.
Biometrics
Biometrics is often considered as a far more secure way of authentication than passwords or digital certificates. It is even safer than smart cards, which may be misplaced. The physical and behavioral traits of a person are taken into consideration in this type of authentication.
Captcha Keys
This is the process of authentication that is used to verify whether a human or a computer bot has logged into the system. Captcha keys are randomly generated alphabets and numericals presented in such a form, that only a human can recognize.
Now, let's come down to the normal computer security authentical processes that we can do at the local level. Setting up a BIOS password for your computer may not be the ultimate security authentication. Removing the BIOS battery from the computer system for 30 seconds, deactivates this security feature. Setting up the administrator password is of utmost necessity. If the administrator password is not set, then any user can log into the computer irrespective of the fact whether he has an account in that computer or not.
The above listed methods are just a few of the widely used authentication methods. In fact, the measures that we take for safeguarding our computer or network are more important than the method itself. Many of us have a habit of naming our networks after the protagonist from our favorite movie. This should be avoided and networks should have sensible names that cannot be easily determined. If you are a network administrator in charge of a closed secure network, then it is always desirable to set your network visibility status to the invisible mode.
How is the top-down approach to information security superior to the bottom-up approach?
The project is initiated by upper-level managers who issue policy, procedures and processes, dictate the goals and expect outcomes, and determine accountability for each required action.
What are the advantages and disadvantages of Hacker?
Hacking is unauthorized use of computer and network resources, it could be remotedly or by directly logging in your PC
advantages: hacking tools are used to test the security of a network, pc etc.
disadvantages: is being used by criminals to steal information and passwords
Is standard email transfer secure Why not How would you make it secure?
No, email is transmitted in plaintext. A secure solution would involve encrypting your email or using a more secure protocol (secure ftp, ssh, https, etc)
How do you prevent information about your computer being leaked via javascript?
Most browsers allow you to disable cookies. This would prevent any javascript function from collecting data about your computer. Unfortunately, cookies can be very useful. They remember logins and passwords for you, and can help make a webpage more interactive. As long as you stay on safe websites, you shouldn't worry about javascript cookies.
What is a spider on a online discussion or message board?
An automated bot for a search engine like Google scanning the forum for pages to be listed, tags, etc.
Why has the Google Earth software been criticized or a bit controversial?
Google Earth has been criticized for the same reason it is so popular which is having the ability to see any place on Earth in high resolution satellite, aerial, and ground-based imagery. Having such imagery and photographs in clear detail showing cars (color, make and models) and people opens up a hornet's nest of privacy issues. If a person is photographed then they can opt-out, assuming they can find themselves in a given photo often months after it was taken. There is no good way to know if you've been photographed.
People caught in comprising acts ranging from two lovers kissing in the park to others committing crimes have been captured for all to see in Google's Street View photographs. There are also national security issues for such up-to-date detailed imagery of military sites, power stations, and the like.
Fortunately Google has taken on itself the task of blurring faces and licenses plates from all Street View photographs to protect personal privacy. In other words, Google does its due diligence to prevent the individual or the vehicle from being identified, but if the filtering and blurring techniques missed something then it's up to the individual to report back to Google.
Advantages of Jackson structured programming?
The main reason modular (or structured) programming is important is that it avoids the increased possibility of data corruption. Of course modular elements still have that risk but that is usually down to the user (passing by Ref instead of by Val etc.). However by using non-modular programming you can easily corrupt data without even knowing it.
Non-Modular code is normally referred to as spaghetti code. Spaghetti code is typically code that uses lots of "GOTO" which although supported by VB should be avoided.
One bad point of GOTO statements other than the fact they jump around unpredictably is their reliance on line numbers. If u add a line in the wrong place it can literally destroy your code.
This is because the GOTO command is basically a one way link so somewhere else in the code. At the end of that code will be a GOTO to get back, this is considered very messy as it leaves a virtual "trail" that can not only make it hard for other programmers to understand but also jeopardise the reliability of data via unknown lines of code changing/interacting with the stored data.
It also means the programmer needs to make sure the GOTO's are in the right place which adds a greater chance of user related mistakes.
"Structured Programming" is a idea that Modularity is closely associated with. It is the idea that structuring the program makes it easier for us to understand and therefore easier for teams of developers to work simultaneously on the same program. One advantage of structured programming is reduced complexity. Modularity allows the programmer to tackle problems in a logical fashion. Also, using logical structures ensures that the flow is clear. It is also a time saver, without modularity, code that is used multiple times needs to be written every time it is used whereas all you have to do is call a function with that code in to get the same result in a structured program.
What is the risk of connecting to Internet wirelessly using someone else's unsecured network?
Connecting to someone else's unsecured wireless network without their permission is against the law. If the owner of the network discovers that you are using his/her connection then he/she has the right to take you to court, as anything illegal that you do on that network would be traced back to them. While in some places it may not be against the law to use an unsecured access point, you should know that the owner of the access point can, in theory, intercept all the traffic you sent through her connection and/or identify your computer, by a unique identifier that your network card sends out (it's called MAC address, or hardware address or link layer address) with each communication. You can practically disable this unique identifier by changing it to various random values, provided the software to do so.
How asymmetric cryptography both requires and support the use of symmetric cryptography?
Lmfao - do Richard kays coursework by yourself instead of asking others to answer it for you.
Can bad occlusion in a dental class 1 case be solved with only the use of a quad helix?
no No occlusal adjustment to the teeth will most likely be needed also. A Quad Helix (or quadhelix) is an orthodontic appliance for the upper teeth that is cemented in the mouth. It is attached to the molars by 2 bands and has four active helix springs that widen the arch of the mouth to make room for crowded teeth, or correct a posterior cross-bite, where lower teeth are buccal (outer) than upper teeth. A variety of this appliance is inserted into attachments that are welded to the bands. In this way the orthodontist can adjust the appliance without removing the bands.
What is the programming language does enovia use?
It's JAVA based on the front end with Html and Javascript for the web interface. The backend can be either Oracle or SQL Server 2005/2008 -- with SQL Server 2008 being be better performance over Oracle on the same hardware and lower cost.
