E-Commerce – Electronic Commerce | Part 2

Electronic commerce in the European Union

Regulations and official sources on electronic commerce

The European Parliament and Council adopted June 8, 2000 a European Directive on Electronic Commerce (Directive 2000/31/EC of the European Parliament and the Council on certain legal aspects of information society, including the electronic commerce in the Internal Market). This has been transposed in France by the Law on Confidence in the Digital Economy 2004.

The European Directive was preceded by isolated policies of member states of the union as France. For example, from October 1997, Francis Lorentz conducted a mission on Electronic Commerce on behalf of the French Government and was presented May 8, 1998, by the Minister of Economy Dominique Strauss-Kahn.

Cross-border electronic commerce within the countries of the European Union

In globalization, the Internet has become a formidable vector of e-commerce. However, issues relating to the purchase of goods abroad reveal difficulties, particularly in cases of dispute.

European countries must in turn translate into national legislation the guidelines for this area, making the rules uniform between each country of the European Union.

In the context of B2C and when a purchase takes place outside the EU should be cautious, know with whom we do business, and be familiar with the conditions of sale. In cases of serious dispute, the only recourse may be filing a complaint in the country of the buyer and the seller’s country. French law protects consumers by stating that a buyer can not be deprived of his right to file complaints in her country of residence.

It seems it is better also have notions of the law of the country which is the seller.

When it comes to B2B, consumer law rather leaves room for the international trade law.

When a product is purchased from abroad, the customs duties and VAT (or equivalent) are payable as if the product was purchased on the national soil.

In practice:

  • For all purchases made within the European Union, there are no customs duties and VAT that applies is the country of purchase. It may be worth buying in European countries where the VAT is lower (for example, when one of Germany was 15%). With France, the departments and overseas territories are considered territories of exports relative to metropolitan France
  • For all purchases made outside the European Union, customs duties and VAT are payable at entry. Since the buyer is usually not present when the command passes the border (most often it is an airport), postal services are sworn to collect these taxes. In general, these taxes are applied in the form of packages or globally (product cost + shipping for example) which can dearer much the final cost of purchase. Private companies are better organized for this work than traditional postal services.
  • Electronic products are often stopped and taxed at the border. Only books that have a VAT and customs duties very weak are never blocked by the postal services because the cost of recovery would be higher than the taxes themselves.

Implementation of electronic commerce

Specifications:

Technical specifications have been adopted for electronic commerce, with ebXML, the English abbreviation for Electronic Business using eXtensible Markup Language (XML). These specifications are based on the XML markup language. This standard is published by OASIS.

ebXML has become an international technical specification (ISO / TS 15000) in 2004. The UN supports the body with ebXML UN / CEFACT, which imposed this specification to the European Union.

Commerce Commissioner

The delegation consists of a comprehensive management development and management of e-commerce of a mark or emblem form a multi-year partnership with the constant concern to respect the image and the universe of the brand.

Inside this operation, an operator partner offers global expertise in each area of e-commerce that each brand could not afford individually (creating e-shop, e-merchandising, e-marketing logistics, customer service, payment service, managing the back office, etc.)

Measure the volume of electronic commerce

There are no official statistics on electronic commerce in France, but estimates based on different sources: panel merchant sites, amount of credit card transactions, payment platforms. In France, e-commerce represents a transaction amount of approximately € 20 billion and € 25 billion if we include the Banking and trading of financial securities online (source: ACSEL). Electronic commerce represents less than 5% of total retail trade in France. This percentage is fairly similar to those of European countries. In the U.S., it is estimated that electronic commerce represents 6% of retail trade in 2008 (source: NBER).

Software solutions for electronic commerce:

  • Intershop
  • Isotools Studio
  • Microsoft Dynamics NAV
  • SAP AG
  • OsCommerce
  • Magento

E-Commerce Security And Legal Aspects

Electronic commerce leads to a set of questions on computer interoperability between computer systems of customers and suppliers, as well as financial institutions involved in the regulations.

Interoperability computing relies increasingly on the use of metadata in most computer components (XML, databases, enterprise resource planning, decision-making and OLAP hypercubes, etc.).

The French government put in place since 2008 many legal rules for limiting the first influx of pirate sites and other hand introduce a levy on businesses that must (the coup) is reported.

E-Commerce – Electronic Commerce | Part 1

Friday, March 12th, 2010

What Is E-Commerce (Electronic Commerce)?

Electronic commerce or online sales, means the exchange of goods and services between two entities over computer networks, including the Internet. The industry gathered at the Federation of electronic commerce and distance selling accreditations.

Electronic commerce is not limited solely to the Internet. Under the interstate commerce companies, is used for many years, networks such as EDI (Electronic Data Interchange). Electronic transactions will also carry over mobile networks. This is called m-commerce (mobile commerce). More specifically, in France since the 1980s, Minitel has allowed the development of electronic business premises services offered on the Internet today.

E-commerce Is Ideal For Distance Selling

When a property is sold through electronic commerce, it is also about distance selling and the laws that apply to prevail.

Among the major goods and services sold via the Internet to consumers (B2C) include:

  • Cultural goods: books, CDs and DVDs, etc;
  • Technological devices: computer, electronics, hi-fi, etc;
  • Tourism and travel: train tickets, flights, rentals, etc.. ;
  • The consumer products with supermarkets online;
  • Printing products: business cards, brochures, business collateral;
  • Products habitat, clothing, childcare, etc.

There are also products sold online exclusively for professionals (Business to Business, B2B) as:

  • Wine
  • Tracers, plan copiers, scanners, etc. for consultancies
  • Construction equipment (meters, lasers, etc.)
  • Commercial vehicle (vans, trucks, refrigerated vehicles, etc.)

As commerce systems specially adapted for the Internet world:

  • Development of digital photographs;
  • Downloading music;
  • Auction between individuals;
  • DVD rental Internet
  • VOD or video on demand.

Finally, many companies offer Internet services, pay or not:

  • Online banking;
  • Insurance online;
  • Press online.

Electronic commerce — another distribution channel for marketing

Different types of relationship in electronic commerce can be distinguished as:

  • E-commerce between businesses, often called B2B, English acronym Business to business;
  • The e-commerce for consumer, or B2C, English acronym Business to consumer;
  • Electronic commerce between individuals, or C2C, English acronym for Consumer-to-consumer. There are websites for sale between individuals;
  • The electronic exchange between a company and its employees, often called intranet or B2E, English acronym Business to employee;
  • The electronic exchange between private companies and government, often called B2G, English acronym Business to government.

Sales combined with the method RIMA

In the world of electronic commerce, the click and mortar expression (or bricks and clicks) refers to companies that offer complementary ways:

  • Sales by Internet (online activities)
  • And store sales or sales point (distribution Classic).

These English expressions are constructed by analogy with the term customary brick and mortar (bricks and mortar).

One might therefore translate this phrase in French: click and shop or internet store. FNAC is a classic example.

These distribution models click and mortar models oppose “virtual” where only trade online is offered to customers. Some operators “virtual” seem to redirect part of their distribution strategy to the click and mortar.

E-Commerce – Efficient Multi-Channel Sales

To develop a multi channel strategy, allows combining Internet, digital television, mobile services and the physical stores. The advantage of such a device is to exploit the growing number of consumers using their purchasing multiple interactive channels.

This form of distribution can also face some obstacles inherent characteristics of the electronic channel. Some consumers are reluctant to pay online and would like for example to pay in stores. A multi-channel strategy is also relevant in terms of logistics network using the store as a stock and transforms them into points withdrawals. Several e-commerce players have opted for this strategy: meilleurtaux.com, pixmania, ldlc.com. Some traditional players in the distribution has in turn put more time to combine the electronic channel and physical channel. We can cite as examples, FNAC or Darty.

In all cases the multi-channel strategy requires a specific organization on many functions: logistics, information systems, customer relationships, price, and promotion.

Chmod Can Give Limited Protection To Your Site

Friday, March 12th, 2010

Chmod Protection:

Chmod (abbreviation from the English language to change mode, change mode) is a command of Unix systems and Unix-like systems, and more generally of POSIX systems to change the permissions of files and directories.

Chmod is also the name of a system call, defined by the POSIX standard, which change the permissions of a file or directory. In fact, the chmod command by invoking the same name system call.

The chmod command appeared for the first time in the first version of Unix from AT & T and is still used in Unix and Unix-like machines.

Chmod

The general syntax of chmod is:

chmod [options] [-] mode file1 [file2 ...]

Mode parameter indicates the changes to be applied to permits.

The double hyphen – (optional) indicates that the following parameters are not considered options.

Among the main options are:

R
Change the permissions of directories recursively listed and their content.
-h
For BSD-derived systems (such as FreeBSD, NetBSD and OpenBSD, and even Mac OS X), where you can also assign permissions to symbolic links, this option specifies precisely to change the permissions of symbolic links instead of those files referenced.

Examples:
Symbolic representation

* Chmod ‘u = rwx “,” g = rx “,” o = x “filename
* Chmod “+ o = rx” filename
* Chmod “= u + rwx”, “go =-” filename
* Chmod “+ u = rws”, “go =-” filename

For the meaning of S also see other Unix permissions.

Octal representation

* Chmod 734 filename

Mode

The mode is a string that indicates how to set or change the permissions of files and directories specified. Can be expressed as an octal number, or in symbolic form.

Octal mode

It is a number composed of one to four octal digits (eg 640 or 4755), according to the octal representation of permissions, which indicates permission to be given directly to the file without taking into account those already present.

For example, a 755 permission set read, write and execute (7) to the owner (first digit), and read and execute (the two 5) per group (second figure) and other (third digit).

Symbolic mode

It is a series of one or more text values separated by commas.

Each value is in turn composed of three parts:

* A first part consists of zero or more letters that select the classes (owner, group, others) for which you want to modify the permission:
ou – select the class concerning the owner
or g – select the class for the group
oo – select the class relative to other users
or no letter or – selects all classes
* A second part consists of a single character indicating whether permission should be added, removed or set to the selected classes:
o + – adds the specified permissions to the selected classes, does not remove permissions already granted but not specified
o = – set the permissions specified in the classes selected, removes any permissions already granted but not specified
o – - removes the permissions specified by the selected classes
* A third part consists of zero or more letters (e.g., r, w, x, s, t) according to the symbolic representation of permits give the permissions to add, remove or set.

Examples of rules are expressed in a symbolic “ugo = rwx”, “u = rwx, go = r”, “+ x”.
Examples of the

* 0755 – sets read, write and execute for the owner, and read and execute for group and others (common for directories and executable files);
* 0700 – sets read, write and execute for the owner, no permissions for group and others (common for directories private);
* 0600 – Set read and write to the owner and no permissions for group and others (common for data files);
* 0640 – Set read and write for owner, read only for the group and no permissions for others (the common data files to be shared);
* + R – adds read permission for the owner for the group and for others. Not remove other permits already present;
*-X – remove execute permission to owner, group and others. Not remove other permits already present;
* Ug = rx – sets the read and execute permission to the owner, remove any existing writable, does not alter the permissions for others;
* U = rx, g = – sets the read and execute permission to the owner, by removing any write permission already exists, remove all existing permissions for the group and for others.

The system call chmod

System call chmod is declared in the header file sys / stat.h:

# include <sys/stat.h>
int chmod (const char * path, mode_t mode);

Type mode_t is a matte (usually a type integer) that represents the access permissions.

The path parameter is the name of the file or directories that change the permissions.

The mode parameter indicates the permissions for the file or directory.
Return value

The return value is 0 on success. If an error is -1, and the variable errno indicates the specific error.

What Is Adware Software

Friday, March 12th, 2010

What Is Adware Software?

An adware is software that displays advertising during its use. These programs are annoying to almost all its users, who, due to the other positive features of the program running the adware, must use it in order to get some work done. Most of the time, the useful free-to-use program also downloads an adware attachment because the free program makes money from the adware software makers. Thankfully, most of these adware programs do not have viruses or malwares included, but they are nuisance programs due to the constant advertisements that they either display or through using pop up windows – sometimes they pop up many advertisements thus making you lose your concentration, production, and temper.

The adware usually contains two parts:

  1. A useful part (usually a game or utility) that prompts a user to install it on his computer;
  2. Part that handles the display of advertising.

The term adware refers sometimes all of the two previous games and sometimes the second part. Some also contain adware spyware to spy on the habits of the user to send targeted advertising.

Etymology

The word “adware” is a portmanteau word derived from the fusion of “advertising” and “software”. The English word comes from adware advertising supported software.

Adware Operation

Display advertising is generally considered by the developer of adware as a way to recoup its development costs, allowing the developer to provide the software free or at low cost. Revenues from advertising permit or encourage developers to continue to develop, maintain and improve the software.

By cons, ads can be seen as interruptions or distractions by users.

Some adware allow the user to get rid of the publicity at a certain cost.

Malware Program

An adware is considered malicious software when the software vendor does not indicate clearly that the potential user will receive advertising while using the software.

Examples of popular adware programs:

  • 123 Messenger
  • 180SearchAssistant
  • 888bar
  • Adssite Toolbar
  • AOL Instant Messenger
  • Antivirus 200 * Family
  • Bearshare
  • Bonzi Buddy
  • BlockChecker
  • Burn4Free
  • ClipGenie
  • Comet Cursor
  • Crazy Girls
  • Cydoor
  • Daemon Tools (the software is downloaded with the Daemon Tools Toolbar QuickTime Task but can be deleted by the user during installation)
  • Direct Revenue
  • DivX
  • DollarRevenue
  • Ebates MoneyMaker
  • ErrorSafe
  • Evernote
  • Ezula
  • FaceGame.exe
  • FlashGet
  • Gamespy
  • Gamevance
  • Gator
  • Gool.exe
  • Kazaa
  • Limewire (on some music downloads)
  • Messenger Plus! Live (The software is downloaded with adware that can be removed during installation)
  • MessengerSkinner
  • Micro Antivirus
  • Mirar Toolbar
  • Oemji Toolbar
  • PornDigger!
  • RealPlayer
  • Smiley Central
  • TagASaurus
  • TopMoxie
  • Tribal Fusion
  • VideoThang
  • Viewpoint Media Player
  • VirusProtectPro
  • WeatherBug
  • WhenU
  • WinAce (now with MeMedia AdVantage)
  • WinFixer
  • Windows Live Messenger
  • WinZix
  • XXX Shop online
  • XXX Toy
  • Zango
  • Zango Toolbar
  • Zwinky

The Eudora email program is an example of a program available in several distribution modes, including mode adware. After a trial period during which all program features are available, the user is offered the following choices: a free (freeware) with limited functionality, adware version (with ads) with all features enabled or a paid version includes all functions without commercials.

Prevention and Detection of Adware

Several contain adware spyware. Programs have been developed to detect and remove malicious software. These programs can detect and remove spyware of adware. The most popular of these programs are: Ad-Aware, Malwarebytes’ Anti-Malware and Spybot – Search & Destroy. It should be noted that these programs are specifically designed to detect spyware and does not detect the virus.

Almost all antivirus software also detects spyware, or offer software to detect spyware. The reluctance of publishers to block antivirus spyware virus directly into them is due to fear of prosecution. Kaspersky, for example, was sued by Zango after blocking its adware.

Some adware programs can even send your privacy related data that is stored on your PC to its makers without your knowledge and, of course, your consent. These programs also keep secret surveillance on your purchase habits, on your browsing history, and every other usage pattern and then send that data over the internet to their makers.

Not only are the hackers involved in making such adware programs, but sadly, even the reputable companies are resorting to these illegal tactics to gather such data for their marketing and research purpose.

Although these adware programs do not harm your computer much, for example, like a virus or other malicious programs, but their data collecting activities, including collecting your private information, makes them no less evil than the virus-like programs.

Using a good adware and spyware removal program can stop these adware programs from running indefinitely on your PC, but not downloading suspicious programs, and also doing a thorough pre-download research using the search engines about any program that you wish to download any such program can at least protect your PC and the very important data present on it to a great extent.

Doing a research about any software is not difficult at all. Using Google or Yahoo, you can easily search for any complaints about the program that you wish to download. There are optional programs present on the internet that can do the same functions for you safely and securely, so do researches for those types of programs too.

Also using a great adware and spyware related software is recommended, but you must take care to always keep these programs updated regularly so that the latest patterns and versions of adware and spyware are covered while they detect your PC for these adware and spyware programs.

Therefore, using a good adware and spyware removal program along with your regular anti-virus program, keep them regularly updated (fortunately, if you run them in automatic mode, they can download the latest patches automatically from their websites), and take care that you do not download and store any program on your PC without first doing a thorough check for adware, spyware, malware, trojans, and viruses, etc.

What Is Spyware

Thursday, March 11th, 2010

What Is Spyware?

Spyware is malicious software that installs on a computer in order to collect and transfer information on the environment in which it was installed, often without the user’s knowledge. The development of this type of software is associated with the Internet which serves as a means of transmitting data.

Spyware Diffusion

Spyware is often included in free software and are usually installed without the knowledge of the user. Spyware programs are usually active only after restarting the computer. Some, like Gator, are stealthy and do not find themselves in the process table (access: (Ctrl + alt + del for Windows), (‘ps’ for Unix). An anti-spyware however powerful can detect and send a warning before installation.

Use of Spyware

Spyware is developed primarily by companies offering advertising on the Internet. To enable the sending of targeted advertising, it is necessary to know its target. This knowledge can be easily obtained by profiling techniques including spyware is.

Spyware Operation

Spyware is composed of three distinct mechanisms:

  • The mechanism of infection, which installs the software. This mechanism is identical to that used by viruses, worms or Trojans. For example, spyware Cydoor use consumer software such as Kazaa vector of infection;
  • The mechanism for collecting information. For spyware Cydoor, the collection is to record everything the user searches and downloads through Kazaa.
  • The mechanism for transmission to third. This mechanism is generally provided via the Internet. The third may be the program designer or company.

The spyware may display advertising offerings, download a virus, install a trojan (what WhenU.SaveNow, for example), capture passwords by recording the keys pressed on the keyboard (keyloggers), spying programs implemented at a given time, or even spy on websites visited.

Vectors of infection

The spyware often attack Microsoft Windows systems because of their popularity and especially the office launched with all rights mostly. Some Web pages may, once loaded, installed unbeknownst to the user spyware, usually by using security holes in the browser of the victim.

Spyware is often found in freeware or shareware, to return their development. Some freeware stop working after removing the spyware associated. There is no known free software – like Mozilla Firefox – which contain spyware.

Finally, some system administrators or network administrators install this software to remotely monitor the activity of their computers without having to connect it.

Popular software containing spyware:

  • Kazaa, which includes Cydoor
  • DivX, except for the paid version and standard version without the encoder
  • The HP printer drivers and probably other brands send information of unknown nature to the site of the mark when printing

Control and Prevention of Spyware

Program that work against spyware

There are many specific software to detect and remove some of the software under Microsoft Windows:

(Warning: There are false antiespion software that install spyware on computers of their users!)

Free Anti-Spyware software:

  • Ad-Aware, developed by Swedish company Lavasoft. Specializing in removing adware. There is a more sophisticated paid version.
  • A-squared Free
  • Spybot – Search & Destroy, a free program that can also suppress other markers of activity on the system (log files)
  • Spyware Blaster protects your browser to install spyware.
  • Windows Defender (formerly Microsoft AntiSpyware) (original included in Windows Vista and Windows 7)
  • HijackThis, this software can detect and destroy all processes running on your computer
  • Ewido Security Suite software detects and eliminates a large number of malware (free version for individuals). Is now called AVG Anti-Spyware.
  • SmitFraudFix
  • AVG Anti-Virus
  • Super Anti-Spyware, Version individuals (Home edition), also known as SAS
  • ComboFix for advanced users

Software-paying (or check, etc.):

  • Spyware Doctor, a utility-class
  • SpyBouncer, extensive database
  • PestPatrol
  • Spy Sweeper
  • Spy Subtract
  • CheckFlow software suite, anti-spyware, surf anonymously and parental controls (French publisher)
  • Videotron Security Services Version comprehensive and effective.

Faux-Software (avoid).

This software, like antivirus, uses databases that are updated frequently. It is recommended to use several of these programs, because none detects all spyware. Even using them all, one detects a portion of existing spyware.

Spyware Prevention

Before installing software downloaded, make sure you have installed an anti-virus and anti-spyware. For added safety, take some additional information by searching for user reviews, which may indicate hidden threats of certain programs.

The use of free software is a good way to fight against spyware, since the sources of these programs are available, verifiable, modifiable, which allows the detection and removal of spyware programs. In the non-free software, as sources are not available, it is more difficult to detect this kind of threat and impossible to eliminate.

Finally, beware of traps. In the past, some programs supposedly designed to fight against spyware contain themselves what kind of threat or proved totally ineffective for the sole purpose of charging a license (if Spyware Assassin by example), etc.

The main vectors of infection are:

  • Cracking software protection type cracks and keygens;
  • False codecs;
  • Free software;
  • False security software;
  • Surfing sites at high risk of infection;
  • Attachments and instant messaging worms.

Controlling outflows

Controlling outflows is mostly carried by the network administrator. Through a firewall, the outgoing flow control block any connection that tries to be from the computer (or internal network) to the outside (usually the Internet), except connections allowed before (we usually allows connections to websites, but allows less often peer-to-peer).

Even if the control of outflow is still poorly developed at present, it is essential in understanding and blocking of certain problems, such as the presence of spyware, as they will be required to connect to the to send out the information they have collected.
