Key words: computer, cyber, crimes, network

Introduction
As you know, the 21st century is the informational age that as the core of computer and network, networking, informational and digital are the features of the 21st century, and computer and network are playing a increasingly important role in people’s work, study and, life and entertainment.

Chinese cyber network was constructed in 1970s, and 1994 was access the internet (Wang 2007). After years of development, networks have already entered millions of households, widely used in production, services and other fields. Chinese first case involving computer crime (corruption using by computer) was in 1986, and the first criminal case detected only computer (the case of manufacturing computer virus) was in the November, 1996 (Wang 2007). In accordance with the recent Chinese Internet Network Information Center (CNNIC) statistics, the number of Chinese internet and computer users is more than a 100 million, which is after US, world’s no.2 (Wang 2007) Computer and network have brought a great convenience to people’s life, but also provide a broad scope for criminals. An internet attacker can enter to another system without any permission, use other people’s account illegally, data destruction, and even intentionally destroy, causing the network paralyzed extensive and serious losses. According to statistics, in 1999, Chinese Public Security Ministry investigated that there were over 400 criminal cases by computer and network criminals, in 2000, the number sharp increased to 2700, and 2001, was over 4500(Wang 2007). Facts have proved that science and technology always has two sides, cyber crime in an endless stream of network in the normal operation order has seriously affected, imposed a strong security pressure to real society.

Types of cyber crime
Crimes Only Put Computer Network as Target
In this kind of crimes, the majority of the non-violent crimes, which means their attack and destruct target are the program and data of computer and network. At the same time, as the development of computer network, computers are attacked and destructed by virus is getting very serious and become a big environmental damage to society. At present, the known kind of computer network crime attack are nearly thousand, the common forms of defensive action mainly have the scan, the password attack, refusing service attack, buffer overflow, network monitor, the virus attack as well as use the hacker software to implement the attack to network (Wang 2007). In April 2001, American government responded to this threat by announcing a $25 million initiative involving the creation of a National High-Tech Crime Unit to counter the growing use of the Internet for criminal activity. The online world is becoming increasingly vulnerable to criminal activity with 43% of the public identifying cyber crime as a ‘problem’ (Burden and Palmer 2003). The network intruder may invade the information system, carries on steals peeps, the duplication, the change, the deletion computer information in the situation which victim does not know, thus harms people’s benefit. This kind of computer network criminality is take creates the biggest destructiveness as target, invades the consequence which creates to be often serious, lightly, then creates the system partial function malfunction, the serious intruding causes the computer system and the network paralyzes completely, and big economic losses.

Crimes Involve National Security and Stability
This kind of crime mainly disseminate harmful information by using network, instigation subversion state power, overthrows the socialist system, divide country, destruct country unification, destruct national unity, the cult to carry on illegal behaviors and propaganda, the crime to put destruction social stability as target. When we check our email inbox, we receive many junk mails frequently, including some are separatist group’s mail. The criminal offender also use some chat tools and other tools to implement crimes, this kind of crime may act according to its use methods and so on IP address implementation track to look up the perpetrator and to carry on the attack, as well as starts the web cam on-line warning, to report and so on way attack computer network crimes.

Crimes Destruct the Order of Economy and Social
This type of crime is basically on the platform of network for sale of fake and shoddy commodities, this will damage others’ commercial reputation, and violations of other intellectual property rights. Fabricating and disseminating false financial information, setting up pornographic web site to disseminate pornographic information, smuggling and money laundering, gambling, all these belong to this category. As Internet is able to deliver image data, then significant pornographic information on the rampage of the network, with the speed increasing, multimedia technology development and digital compression technology development, pornography is increasing the frequency approached on Internet by multimedia, such as videos and pictures. Information shows that there are 230,000 more than pornographic web site all over the world. A statistics by a website indicate that, there are nearly 2.4 million visitors per day from the most 250 popular pornographic websites in the world. In recent years, the number of dissemination of pornographic materials in Chinese personal web page was also sharp rose, in only a season, the Chinese public security organs investigate that there are more than 200 cases of on-line production, dissemination of pornographic materials (Wang 2007).

Crimes Violate People’s Right, Property and Other Legitimate Rights
This type of crime is insulting and slandering people, Illegally intercepting, tampering, and removing others electronic mail or other data, and infringes upon personal freedom of communication and secrecy of communications, theft, fraud, extortion and blackmail on network. Criminals send large quantities of physical offensive articles and rumors by electronic mail, bulletin boards and forum for a variety of purposes. Network has a feature of openness, and send 1000 emails in a short time is very easy, so the impact and consequences of cyber crime are not traditional crime can be compared with.

Most of us are familiar with the problem of viruses, i.e. code which is usually disseminated by email and which will cause a computer to perform specific functions, some harmless, others less so. Compared to viruses such as the ‘LoveBug’ which was released two years ago and paralysed more than 100 million users, the virus released by Mr Valler caused a level of disruption which could be classified as “minimal”. In the US, case law had until recently been moving in the direction of recognizing that computer data in itself constitutes a form of property such that it could be stolen and (more especially in the circumstances of the cases concerned, which related to claims under an insurance policy), damaged (Burden and Palmer 2003).

Features of Cyber Crime and Researches
There are significant differences between cyber crimes and traditional crimes, the main characteristics are:

1. Celerity and Nationless
The most important feature of the computer network is the connectivity, people can enter any web pages by a web link, so the information transmission through network is very convenient and fast. Network criminal activities in the process is completely broke away from the time limit, it is almost at any time, in any place send and receive data and information. The dissemination of information networks can be produced in a manner, B and C, to send the server into their own web page, and it is undefended. The Internet is a breakthrough in the countries of the geographical restrictions, people throughout the world will be able to provide information sharing resources. No matter when and where can download, visit the world, any corner of the information or the dissemination of information, any corner of the world. The world not to be very difficult to really contain computer networks of crime spread.

2. Imperceptibility and interactivity
The rate of cyber crimes is very high. According to statistics, 99% of the computer network cannot be found (Wang 2007). In addition, in the admissibility of such cases, investigation and evidence collection difficulties. These features of network make cyber crimes with a high degree of secrecy, and increasing the difficulty of cases detecting. According to a survey has found that the computer network only accounted for the crime of the practical implementation of the total crime 5%-10%, they are often found many criminal acts as a result of the accident factors, such as accomplices of the information or lead to a computer network failure. The computer network crime hidden and anonymous, made on the computer network characteristics of the crime detection is very difficult. In America, computer network crime detection rate was less than 10%, the conviction of less than 3%. The news coverage, computer network only 11% was reported that only 1% of the criminals were investigated, And as high as 85% over the crime is not found.

3. Smart and Technically
Most of the cyber crimes are acts through the insidious and meticulous arrangements, use professional computer network knowledge of the intellectual crimes. As such crimes, criminals only input error instructions to the computer, tampering with software programs, criminals time is short of computer hardware and information carriers will not cause any damage, crimes without leaving any traces of the general, so it is very difficult to detect the internal computer software changes.

Generally speaking, only have a high level of computer network technology, and good practical technology can avoid security system of control. As a result, most of cyber criminals have computer network professional technologies. They anticipate the weaknesses and vulnerabilities of network, and good at using computer and network technology, cyber crimes can be done in a short time, means complex hidden, many crimes implementation are done in a moment, and there is little trail left.

The Features of Cyber Criminals
Main Body
Criminal main body means the actions which are danger to society, and the individuals and units which should be bore the criminal responsibility. From the specific performance of computer network of cyber crime, crime main body has feature of diversity, all ages, occupations are able to in the cyber crime. As usual, the criminals main body must achieve the level of computer and network knowledge.

Subject of Cyber Crimes
Cyber Crime in subjective performance for the direct intentional, is to demonstrate their ability of invading computer network, the perpetrator was a clear have the “necessary” idea to invade. That reveals a highly subjective intention.

The Object of Cyber Crime
The Object of Cyber Crime is to protect the Penal Code of Criminal acts against computer network of social. Illegal use of network invasion or direct penetrated computer crimes in violation of the computer system in all human rights. On the other hand, it caused the damages of country’s computer information management order, and it is possible for the victims of the computer system of data relating to the third party’s rights hazards. As a violation of the computer network management laws and regulations, invasion state affairs, national defense construction, advanced science and technology fields of computer system. Computer information system functions, data and applications to delete, modify, or destroy computer systems software, hardware, equipment, acts against the security of computer systems and computer networks are peeping, copy, change or delete the computer information, fraud, aiding and abetting crime , dissemination of Internet pornography and the use of computer networks insult, slander and intimidation and other crimes. This network of people behind the acts of crime can only be positive as, and in the national legislation of the term can be invasive, delete, increase or interfere with the production and so on. Network characteristics of a transnational nature of crime, perpetrators take advantage of the network, anywhere in the world, from any node on the network into the computer network, can any one network node to other computer systems doing Invasion, assault and criminal.

Laws against Cyber Crimes
To develop a special “computer network crimes law.” Although the “Criminal Law” on the computer network crime specific provisions, but with the rapid development of modern science and technology, ever-changing computer and network technology, computer network crime situation is complex and diverse. In order to more effectively combat crime computer network, computer network in China should draw lessons from foreign experience in relevant aspects of crime in order to adapt to a wider variety of computer network crime challenges.

Increase the unit provides the computer network crimes. Accompanied by wide spread of computer networks, computer network crimes unit there is inevitable. However, according to China’s “Criminal law” the provisions of article 30: corporations, public institutions, organizations, groups in the implementation of the act that endangers society, the law provides for the unit of criminal should take the responsibilities. This means that only laws clear that a crime may constitute a unit, the unit can become the subject of the crime. In China’s current criminal law under the provisions of two units of computer network crimes were not able to become the main, this unit actually excluded from the main computer network outside the crime, no doubt with the computer network crime trends incompatible, it is necessary to the main unit into the scope of computer network crimes.

Improve the computer network system of criminal penalties. Computer network is often the subject of crime control computer network technology, intelligent crime, his criminal purpose is usually to seek illegal interests or technical challenges. Freedom in imposing sentence on the computer criminals, while supplemented by property eligible for criminal punishment, and also the current world of computer crime legislation in general practice. Therefore, in order to effectively combat, deter and prevent such crimes, the criminal kind of response to the current criminal law to make adjustments to property, criminal and qualification of additional punishment

Appropriate reduction in crime of the main age of criminal responsibility. The young age of the computer network of the main crime is a status quo can not be ignored, this is also the main trend of younger age have occurred in China. However, my “criminal” Article 17, paragraph 2, states: “The full 14 years of age under 16 years of age who commits intentional homicide, intentional injury resulting in serious injuries or death, rape, robbery, drug trafficking, arson, explosion, poisoning crime shall bear criminal responsibility. “This means that, in addition to the terms of the provisions of the criminal than the 8, the age of person who has any harm to others, and social behavior are not dealt with as offenders. Thus, in the Criminal Law crime of illegal intrusion into computer information systems, the crime of destruction of computer information systems do not include the principal minors of the age. However, the judicial practice of view, young “hacker” is a destructive force to be reckoned with, which of the Criminal Law provisions on the age of criminal responsibility had a shock. To respond to this impact, the paper that China’s criminal law should be full 14 years of age of minors under 16 years of age into the main body of the scope of computer network crimes.

Conclusion
The whole society should attach great importance to the serious harm of computer network crimes. Strengthen the computer network crimes legislation, expand the public security organs in crime prevention and detection of computer network functions work; a multi-channel computer network crime reporting system, improve the network behavior of the regulatory mechanism. Undertaken simultaneously moral and legal education computer network, network security, protection, concerning the vital interests of broad masses of users, the police rely on public security departments to combat and prevent the network, not enough to form a protective network of effective mechanisms of social security, only through the general education Internet users, raising awareness of the law, strengthen the consciousness of the Internet to refrain from contact arm of the law, and make users understand the various crimes against the computer network technology, network security to improve their ability to self-protection in order to fundamentally solve computer security issues.

In short, the computer network crime is a new form of crime, with the growing popularity of the Internet, most of the conventional crime associated with the network, resulting in increasingly complex network of crime, this requires that we the public security organs must cybercrime combat and prevent a new height to that understanding, make adequate technical, physical and psychological preparation, so that online crime to the country’s political and economic security posed by the loss as small as possible, as far as possible the next generation of physical and mental health little threat to defend the country and the people’s security contribution to the full force of our police officers.

As the important component’s advertisement of marketing , when we carries on the process of the plan, the creativity, the design, we certainly needs to consider consumer’s psychological characteristic, Therefore, both in the demand mode or in the form of advertising on the performance must be carefully considered that postmodernism have an impact on advertising and the audience.

1.Postmodernism On The Impact of Advertising Creativity

1.1 Manifestations and Subversion

1.1.1 Anomaly

Take “Nike Advertisement Playbill” as the example, what in the picture first appears will be the rainstorm to London, a football flies to the building have the Nike poster advertizing with a very quick speed, the stars in the poster is moving up. They pick up the ball and kicked the ball out and broken the corner of the building, the ball is fast to fly away, then players become another static posture. Screen also converted to a bright sunny England, another poster inside players have also moved the ball up and pass the building also broken a corner. Then turned the ball across the sea, after sunset, past China, finally arrived in Japan under the lights. Different star player catch the ball in the world’s poster pass it and shoot it. There are no lines throughout the ads, but this ad is due to various factors anomaly firmly grasp the consumer’s attention, and left a deep impression on the consumer’s brain. But at the same time, this advertisement actually not tends to be mediocre causes the marketing effect because of the counter-tradition’s performance method, on the contrary this ad back to the audience to leave the “Nike products are sold worldwide, the global movement of consumers to share the exciting life of Nike,” such impression, this equips the big brand with the Nike international movement the image to be consistent.

1.1.2 To Break The Logical Relationship

More and more advertisers have such a trend, that is, the performance of the screen without any logical constraints. In many TV ads, we will see that many seem completely unrelated picture of fragments clipped together, Screen switching is no logical constraints, story neither, it is difficult to understand advertising really want to say. But these contents actually have the very strong visual impulse, also will often cause person association some products or the brand characteristic.

1.1.3 To Subvert the Traditional Aesthetics

To a certain brand of jewelry as an example of print ads: In the picture is about one 60 years old the whole face wrinkle gentle woman and a young actually very cloudy man, women wear a lot of the brand’s accessories, and then a hand-hooked from the front man’s neck. Comes from the traditional esthetics’ angle to see this print ads, is really very difficult to discover has any esthetic sense, even may say, this advertisement is ugly. Whether speaking from the screen or from the contents of the screen displayed on the relationship between the characters, this is all under the traditional thought. But this advertisement actually through this form, displayed the accessories which the business wanted to propagandize to be able the charm which brought to the human. Meanwhile for the target consumer group of businessmen – the rebellious young people to have a certain appeal.

2.The Way of Demand Is Change

2.1 Induced by thinking, rather than indoctrinate

Under the influence of postmodernism, consumers try to destroy all dogmatisms. They are very difficult to willingly accept the thought which others instill into, even if knew that is correct, because they more pondered compared to any other’s when consumers from their emotion angle, this enables their viewpoint often to have the very big difference. “wears away the rock with water” the Tai Chi-style thinking induced by active forms of advertising to consumers in the face of postmodernism affected by the impact of consumers often can play better results.

2.2 Inducing Desire, Not Describing the Value of Goods

Simply tell the consumer goods may not be able to bring value to be able to impress the people, induce consumers to enjoy the material to meet the emotional needs of the desire to enhance the advertising effect is the greatest force for consumption.

2.3 Induced Resonance, Rather Than To Remind the Situation

After under the modernism ideological trend’s influence, consumer’s emotion is a little chaotic disorder, consumers tend to seek emotional stimuli to reflect the self-existence, this is a fetishism, but it is not a simple pursuit of material, but need to rely on the material to meet the emotional sustenance to achieve self-awareness. The entire advertisement for person’s feeling is very peaceful, a very harmonious life scene, actually to bring people surging currents of thought about love .This ad is not very realistic from the need for people to call up to the demands, but only with the emotions between parents and daughters exchange for such a little story. But the advertisements to remind consumers to communicate love, secretly, while it very cleverly shows the value of the product, so that consumers look at this ad do not produce feelings of exclusion.

 3.The interaction of Postmodernism advertising and Chinese    local culture

The influence of Postmodernism ideological trend deepens day by day to Chinese advertisement creativity, but if wants to take root deeply in the Chinese nation tradition culture must everywhere unify China’s cultural tradition and the actual national condition. Only to produce good blend of both and interaction in order to promote each other, coexist and prosper.

When the post-modernism appears in the core of Confucianism as the ideological context of Chinese traditional culture, it will surely be affected and transformation. The creative Postmodern advertising mode, it must combine the characteristics of traditional Chinese culture, comprehensive consideration of the differences between China and the West in order to achieve good results.

When the radical postmodernist and the Confucian “peaces is precious” thoughts meet, that requests the advertisement creativity is necessity to differ from the performance with other cultural linguistic environment in performance.

Postmodernism truly brings a lot influence to our society; it exists within society and connects closely with social ideology and economic ideology by advertisement. We must get with its influence within our advertising creativity, combine with Chinese local culture, but differ from foreign culture, make use of postmodernism to make better development of Chinese Advertising.
