1. There are three basic anti-theft methods: personal defense, physical defense and technical defense. Among them, civil air defense is the only reliable way to prevent and stop theft. Physical defense is one of the most widely used basic protection measures. Technical prevention is a more subtle and reliable preventive measure, which can immediately detect the invasion, replace the guards of personnel, and stay on alert for a long time without fatigue and slack. Students should pay attention to the following points in the anti-theft work at school and at home:

Close the window and lock the door at any time, don't be afraid of trouble. Students must get into the habit of turning off lights, closing windows and locking doors, so as to prevent thieves from entering.

(2) Don't just hang out with people who don't know the details. You can't just be loyal, emotional and unprincipled. If you lure the wolf into the room, you will regret it. This lesson is painful.

Anyone who finds suspicious behavior should be vigilant and pay more attention. When criminals steal, they often find various excuses, such as who to look for or what goods to sell. When they saw that we were lax and free to go in and out, and Daimon Masaru was open, they walked back and forth, peeped around, waited for an opportunity to find out the situation, and then pried the door and twisted the lock to steal. When encountering such suspicious people, students should take the initiative to ask, and if there is a legitimate reason, they can generally make it clear. If the visitor can't give a proper reason and has many doubts, he will be flustered and need further inquiry. If necessary, he can be asked to show his ID card, student ID card, work permit and other identification certificates. If it is found that the holder carries evidence that may be tools or stolen goods, on the one hand, he can send someone to talk to him to delay the time, on the other hand, he can call the school security department or the public security organ to come and investigate as soon as possible.

(4) Students should actively participate in the safety duty in classrooms and dormitories, and assist the school safety department to do a good job in safety prevention. By participating in the practice of security work such as duty and patrol, we can not only protect our own and others' property safety, but also enhance our awareness of safety precautions and exercise and increase our social practice ability.

⑤ Take care of your keys, including those of classrooms, dormitories, bags and drawers. You shouldn't lend them to others or leave them lying around to prevent "uninvited guests" from copying or stealing.

2. Anti-theft measures for several special items that are easy to steal

Cash is the first choice for all thieves. The best way to keep cash is to deposit it in the bank. Especially when the amount is large, it should be deposited in the bank in time and the password should be added. The password should be a number that is easy to remember and difficult to decrypt. Never choose your date of birth as your password. This is because once the passbook is lost, it is easy to be impersonated by familiar people. In particular, passbook, credit card, etc. You should not put it with your ID card, student ID card and other documents to prevent thieves from stealing it together and taking the initiative. When depositing and withdrawing money in the bank, check the password gently and quickly, and don't make a noise when no one is watching. If you find that your passbook is lost, you should report the loss to the deposit bank immediately.

② Various valuable cards, magnetic cards, etc. These valuable cards should be properly kept in case they are lost or stolen. The best way to keep all kinds of valuable cards is to put them in your close-fitting pocket with buttons or zippers at the mouth. The password you use must be kept secret. Don't tell anyone easily, in case there are uninvited guests around you. If you have to take off your clothes when taking part in physical exercise and other activities, you should lock all kinds of valuable documents in your own box and keep your keys properly.

The theft of bicycles is a great public hazard. Campus is no exception. When buying a new car, you must go through the formalities of settlement with the relevant departments. This is because some criminals steal cars without steel seals to facilitate the sale of stolen goods. Once a car without a stamp number is lost, it is difficult to find it. Install anti-theft car locks and get into the habit of parking and locking. You'd better spend money to park your car in the parking lot when you ride a bike to a public place. If parking for a long time, it is best to strengthen anti-theft facilities, such as fixing the car lock on the object or putting it indoors. Once the bicycle is lost, it should be reported to the public security organ immediately, and relevant information such as valid certificates and certificates should be provided for timely search.

4 valuables, such as gold ornaments, watches, walkman, high-grade clothes, etc. Those that have not been used for a long time should be taken home or entrusted to a reliable person for safekeeping. When not in use, it is best to lock it in a drawer or box (cabinet) to prevent it from being stolen by pickpockets and intruders. Don't misplace or lose the door lock key. On valuables and clothes with high value, it is best to make some special marks on purpose. Even if they are stolen, they will be recovered more easily in the future.

3. How to deal with theft cases: In case of theft, students must handle it calmly:

(1) immediately report to the school security department or the public security organ, and at the same time block and protect the site, and no one is allowed to enter. Don't rummage through your belongings at the scene, and don't rush to see if your belongings are lost. This is of great significance for public security personnel to accurately analyze, correctly judge the scope of reconnaissance and collect criminal evidence.

(2) If a suspect is found, he should immediately report to the school security department or the public security organ. Personally, I don't advocate students catching cattails here, but we should remember the gangsters' facial features and escape direction, and pay attention to the ways and means.

(3) Cooperate with the investigation and objectively answer the questions raised by the public security departments and security personnel in a realistic manner. Actively provide clues and don't hide the situation. The school security department and the public security organ have the obligation and responsibility to keep secrets for students who provide information.

④ If the passbook is found stolen, you should report the loss to the bank as soon as possible.

(B) Network security issues

With the rapid development of Internet in China, online dating, online chatting and other activities have gradually become popular. QQ, as a network instant messaging tool, has always been welcomed by netizens, especially teenagers. More and more teenagers are using QQ to communicate with netizens online, and I think the students sitting here are no exception. At the same time, the security problems of network activities are also highlighted.

Online dating and chatting tools provide great convenience for the communication between netizens. Many netizens have found intimate friends on the Internet, gained a lot of useful knowledge and solved many problems in their study and work. Many netizens have benefited a lot. However, the network is face-to-face communication after all. The network transcends the barrier of time and space, and the margin is blurred. There are all kinds of netizens, which easily make young people who are not deeply involved in the world feel illusory, and netizens are easily misled when making friends. This happens from time to time, which is worrying. Based on this anxiety, it is necessary for us to remind students, especially young netizens, to pay attention to the following matters when participating in online activities and strengthen self-protection:

1. Although QQ has expanded the communication of netizens and is easy to use, it is easy to find netizens from all over the world online, but students should pay attention to distinguish the difference between network and reality and avoid being too addicted to the network.

Just as some people use e-mail to spread bad information, a few people also use chat tools to spread some boring and harmful public information to achieve their own illegal purposes. Students should abide by the law and discipline in online activities, consciously self-discipline, and not participate in the production and dissemination of harmful and useless information.

3. At the same time, there will be a very small number of netizens or criminals with bad consciousness in the network, so students should take precautions. Students should pay attention to personal protection awareness when filling in QQ personal data, so as to avoid unnecessary harassment of personal life by bad elements.

Students should try to avoid meeting netizens directly or participating in various networking activities without knowing each other, so as to avoid being used by criminals and endangering their own safety.

Here are a few cases:

A female middle school student was raped by "netizens". Two female students in a vocational high school, Qian Qian (net name) and Shanshan (net name), met a male net friend while chatting online. After the meeting, male netizens tricked them into the hotel, and a young man raped Qian Qian because Shanshan tried to resist the attempted rape. Because the suspect used the online name when meeting the victim, but did not leave his real name, and the phone number and pager he left were also verified as false, the case detection was deadlocked. Later, after careful investigation by the criminal police brigade of the municipal bureau and the computer security supervision department, the criminal suspect who claimed to be "Dayu" on the Internet was found. Finally, the police surrounded it in an Internet cafe, and Daewoo was still searching for new prey online.

In addition, a girl criminal aged 15 was severely punished. After leaving home for many days, parents were anxious to report the case to the public security organ. According to her classmates, the girl is addicted to online chatting. Before she disappeared, she used to surf the Internet in a bristle bar not far from home. According to this clue, she finally found that the girl met a man at the bristle bar. After 1 1 day, the public security organs finally found and rescued the abducted girl in Mane province. After the girl was rescued, she explained that it was novel to meet with netizens at that time, and all the netizens she contacted spoke very well. She wanted to know them, but she was abducted out of curiosity. Although the criminal was severely punished, the girl will leave painful memories and lifelong regrets.

Through the analysis of the above two cases, we can see that teenagers are easily confused by the virtual image of the network, have strong curiosity and lack the ability to improvise, so they are easily used by people with ulterior motives and lack the ability to protect themselves. Teenagers should realize that the image in the network cannot represent everyone's true face. When participating in network activities, we should raise safety awareness and strengthen self-protection. Don't meet netizens casually, especially strangers alone to avoid accidents.

In addition, teenagers lack experience in dealing with emotional problems, have a strong sense of freshness, are easy to indulge in online dating and even develop online dating. Once there is a problem, it is difficult to understand it rationally and treat it correctly. In fact, online dating and online dating are very different from dating and romance development in real life, and the shortcomings of netizens in real life are easily covered up by the internet. Faced with such problems, teenagers must keep a normal mind when making friends, concentrate on their studies and work, analyze objectively, and avoid indulging in the internet.

(3) Anti-fraud safety knowledge

1. What should I do if I encounter a packet loss trap in the street?

In life, you may encounter this situation. A person "unintentionally" leaves a bag in front of you, and the lost bag is often full of counterfeit money and fake gold jewelry. Another person pretends to find the lost bag with you, asking for half of it, and letting you get most of it with sweet words, but asking you to take out money or gold ornaments as collateral. At this time, please don't be greedy for small profits and get dizzy.

2. What should I do if I encounter fake gold and fake medicine fraud?

Liars often use fake gold ingots, fake herbs, fake electronic parts and fake stamps, saying that they need money urgently at home, hoping to sell them at a low price, and then arrange some "matchmakers" to buy them. If you can't judge the authenticity of the goods, don't pay easily.

3. What if someone exchanges foreign currency with you for RMB?

Foreign currency exchange should be handled at the designated bank. If you meet someone who wants to exchange money with you, you can't tell what foreign currency is. If it's true or false, you'd better ignore them to avoid being fooled. They usually have two or three people, one pretending to be a money changer and the other pretending to be a bank worker. Using secret coins to impersonate currencies with similar appearance and high exchange rate, such as US dollars, French francs, Singapore dollars, etc., defrauding the victim's money on the grounds that there has been a car accident in doing business in other places or there is an urgent need to change money, and impersonating "bank staff" to identify the authenticity. Sometimes these street currency exchange tricks are performed by foreigners, so we should pay more attention to them. The foreign currencies defrauded in the street are generally counterfeit or worthless foreign currencies, and the deceived often suffer heavy losses.

4. You need to buy nervous tickets when you go out. What if you meet a stranger and take the initiative to help you buy tickets?

Please believe in yourself and your own judgment. The ticket you bought in line at the window is real.

5. When traveling, what should I do if I meet enthusiastic fellow travelers and invite you to dinner?

Don't be fooled by other people's kindness, thank him for his kindness and politely refuse.

6. What should I do if I win the prize for free promotion?

When you are walking in the street, you meet a person who sells products to you for free. When you open the product and congratulate you on winning the prize, don't be fooled, because when you finish winning the prize, scammers often lie about paying some taxes on the prize, thus defrauding you of money.

7. What should I do if I encounter hooliganism?

When you go out, you suddenly collapse in front of your car, falsely claiming that you knocked him down and asked you to pay for medical expenses and damages, or they deliberately collided head-on with you and threw a worthless color changer, the so-called "gold watch", and said that you broke him and had to compensate him: you don't have to argue with him. You said nothing, let's go to the police station to deal with it. This move is ineffective. You can say that you have no money with you.

(4) Anti-robbery safety knowledge

1. When depositing or withdrawing money in the bank, if it is a large deposit or withdrawal, someone must accompany it. When checking the password, pay attention to people within one meter. Please don't throw away the wrong deposit and withdrawal slip, but take it somewhere else to shred it, because your account number and ID number may be left on the deposit slip.

2, we often encounter door-to-door sales in life, please remember that there will be no pies in the sky, all refuse, don't entangle, and don't open the door to let them in.

A stranger said that you would send things to your family. You should make a phone call to check and find out the situation at home before opening the door. Don't worry. Open the door now. There are also reasons for wanting to enter the house to copy water meters, gas meters and maintenance. When you are not sure whether it is true or not, you might as well politely refuse until your family comes back. Never open the door easily.

4. How to prevent robbery when walking by bike? Car robbery has always been a high-incidence street case, and the victims are often single women walking at night. There are two modus operandi. One is that two people ride a motorcycle and the person in the back seat grabs it. The other is carjacking. The crime time is mostly from 10 to 5: 00 at night, and the crime place is mostly in alleys and poor intersections that are easy to escape. Women who go out at night should pay attention to walking in crowded and bright places, and it is best to walk together, and pay attention to prevent motorcycles and cars from approaching quietly. Please fasten the mobile phone box to your waist. The satchel of female students should not be carried on one shoulder, but should be slung on the body obliquely to prevent shoplifting or cutting off the bag. Handbags are indispensable items for women, and often contain cash, credit cards, keys, address books, mobile phones and so on. Gangsters often aim greedy and evil eyes at ladies' handbags at night. At work, we found that many women casually hang their bags on their shoulders or put them in the basket in front of their bicycles, which is actually very unsafe. If you walk with a bag, it is relatively safe to carry it in your hand or slung it over your chest. When riding a bicycle with a bag, if the bag is placed in the front basket of the car, you must wrap the belt around the handlebar several times, which is short enough for gangsters to catch it. If you carry it, of course, you should lean your back like a primary school student and pay attention to hanging your bag on your chest.

5. Riding a bicycle during normal driving and finding that the car suddenly can't ride. First, hold the items in the basket firmly and carry the bag on your body, because criminals often throw cloth strips and steel wires at the back wheel. When you find out the reason, take the opportunity to grab the bag.

6. When a woman goes home alone at night, she should pay attention to whether someone is watching behind her. If there are always people following behind in remote sections, we should be especially vigilant. When you suspect that you are being followed, go down to a place with bright lights and concentrated pedestrians; When you are sure to be followed, you should avoid stopping to confront each other, but just enter a busy shop or a place with security personnel, or find the nearest resident's house to ask the owner for help and call family and friends. When you meet strangers upstairs and downstairs, on the stairs or at the gate of the yard, you should be careful, especially when you enter the house. Don't enter the building with strangers. Who should you ask if necessary? Prevent the other side from suddenly attacking.

7. How to deal with gang violence

In the face of gangster violence, women can take the following measures to save themselves. First, they can find out earlier that gangsters want to do bad things, and gangsters are not skilled veterans and have small bodies. Women can grab handbags or other things within reach and slam them in each other's eyes, while shouting for help and escape. Second, when the gangster covers his mouth and drags it to a secluded place defenseless, he should calm down and act like he is in abnormal fear, wait for him to let his guard down, and kick his crotch with his knees while he is unprepared to lift his feet. Or grab a handful of sand and throw it at the gangster's eyes. In addition, you can pull out the hairpin and attack the gangsters' eyes, ears, nose and other fragile parts. Third, if you can't get rid of it, you should pay attention to remember the physical characteristics of the gangsters and call the police in time after you escape.

8. When encountering an accidental traffic accident, you should call the police for help quickly, write down the license plate number of the accident vehicle, let others call the police quickly and get in touch with their families, remember the witnesses, and try not to deal with the accident vehicle and personnel alone.

9. What if I don't find the gold? It is the traditional virtue of the Chinese nation not to pay bad money. Those who don't pay back will be punished by law in addition to moral condemnation. Refusing to return the found articles constitutes a crime of embezzlement and can be punished with fixed-term imprisonment of not less than two years but not more than five years and a fine. Therefore, when you find that your lost items have not been returned after being picked up, you can report them to the police station.

(5) Other safety precautions:

1, what should I pay attention to when using liquefied gas at home? Liquefied gas cylinders should be placed in a well-ventilated place, and there should be no open flames and heat sources within a certain distance. Gas cylinder valves and pipe joints shall be airtight. It is forbidden to use open flame to test leakage, and the residual liquid in the gas cylinder shall not be dumped by itself to prevent the residual liquid from spreading, evaporating and burning.

2. If gas and liquefied gas leak at home, first turn off the main gas switch and liquefied gas valve, and open the doors and windows to let the air circulate naturally. Never turn on the light, make a phone call or make a mobile phone indoors, and don't switch on or off household appliances, so as not to cause electric sparks and explosions. Hurry to clear the old people and children and call a safe place for maintenance. And notify the surrounding neighbors to make corresponding preparations.

If there is a fire, don't panic and keep a cool head.

(1) Call 1 19 to call the police and shout for help to the neighbors.

(2) Evacuate the elderly and children at home to a safe place;

(3) cut off the power supply at home;

(4) Under the condition of ensuring your own safety, use the existing conditions nearby to extinguish fires and evacuate articles, and don't be greedy for property;

(5) When away from the fire scene, cover your nose and mouth with a wet towel, bend over, and evacuate to a safe area in the direction opposite to the fire point. For example, if a high-rise building catches fire and the safety passage is blocked by fire, you can lean your upper body out of the window, breathe fresh air and wait for rescue. Never jump off a building.
