With the advancement of the Internet and mobile phone technology, mobile payment has become the main method of payment in society.
In the 3.15 evenings of previous years, telecom fraud and mobile payments were on the list. As the network penetrates into people's daily lives more and more deeply, the problem of information security that comes with it becomes more and more prominent.
The endless stream of user privacy exposures and the frequent Internet extortion problems have made it impossible to ignore the information security issues of the Internet age, especially those with a lot of personal information.
Recently, the Jiangsu Provincial Consumers Association issued a "news report on mobile phone application infringement of consumer personal information security" pointed out that the current mobile phone APP has the right to obtain access rights, which violates the consumer's right to know.
Relevant personnel after testing about 100 apps, found that 79 of them can obtain location rights. In the "Phone & Contacts" section, there are 14 apps that can listen and hang up.
The data shows that the number of mobile APPs in China has exceeded 17 million. The rapid development of mobile payment has increased the risk of user information leakage to a certain extent. In the case of mobile security software, payment traps accounted for up to 90%.
Previously, the National Computer Virus Emergency Response Center found through the Internet that more than ten illegal mobile applications existed in the mobile application publishing platform. The main hazards involved malicious transmission and privacy theft. At the same time, the Ministry of Industry and Information Technology also found a number of problematic applications in the test, and removed multiple apps.
Online shopping rights expert and analyst of the legal rights protection department of e-commerce research center Yao Jianfang believes that the mobile payment industry continues to break out, bringing consumer market cakes to attract physical businesses and e-commerce platforms to compete. However, consumers also need to purchase on demand, cautiously place orders, beware of fraud in the mobile payment link, retain credentials, and pay attention to maintaining their legitimate rights and interests. The relevant departments should take the lead in unifying the standards as soon as possible.
It is reported that the National Security Standards Committee has established a standard for secure mobile phones, which is intended to study and develop mobile phone security standards, which will include network security protection capabilities for critical hardware and software information infrastructure, system security levels, and APP permissions restrictions.
In terms of information security, mobile phone manufacturers have become an important part of their efforts.
According to industry analysts, in the mobile phone market, different mobile phone manufacturers have different understandings and different solutions, which leads to differences in product protection levels. Biometric technology is currently the best protection for user privacy of smartphone products.
At present, many mobile phone manufacturers have also launched their own "biometric technology", such as "iris recognition" and "fingerprint recognition".
It is understood that fingerprint recognition, face recognition and iris recognition are the biometric identification schemes currently used by mobile phone manufacturers. Among them, face recognition is difficult to be forged but the application is in the early stage, and fingerprint recognition is the most widely used. Iris recognition is rarely used because it requires high technical strength from mobile phone manufacturers. However, since each person's iris has a uniqueness that is not replicable, the safety level of iris recognition is the highest in current biometrics.
At present, some biometric identification technologies used by some mobile phone brands are fingerprint recognition, but with the enhancement of information security awareness, higher requirements are imposed on the biometric identification method of mobile phones.
According to Samsung insiders, Samsung has adopted three biometric solutions on the latest Galaxy S9 to improve the security protection level.
The industry believes that in the Internet and big data era, information security concerns everyone. When developing products, mobile phone manufacturers should not only consider the user's habits and convenience of product functions, but also develop a system to protect user privacy and information security. With the emphasis on information security by mobile phone manufacturers, biometrics will usher in a new slogan.
A DC motor is any of a class of rotary electrical machines that converts direct current electrical energy into mechanical energy. The most common types rely on the forces produced by magnetic fields. Nearly all types of DC motors have some internal mechanism, either electromechanical or electronic, to periodically change the direction of current flow in part of the motor.
DC motors were the first type widely used, since they could be powered from existing direct-current lighting power distribution systems. A DC motor's speed can be controlled over a wide range, using either a variable supply voltage or by changing the strength of current in its field windings. Small DC motors are used in tools, toys, and appliances. The universal motor can operate on direct current but is a lightweight motor used for portable power tools and appliances. Larger DC motors are used in propulsion of electric vehicles, elevator and hoists, or in drives for steel rolling mills.
Dc motor areas of application: smart home field, robotics, precision medical equipment industry, automotive drive field, electronic products and personal care equipment
Application of the product:
Features: high torque, low noise, small volume, light weight, easy to use, running constant speed, etc., can also be matched with various gearboxes to change the output speed and torque.
Features: small volume, fast speed, stable performance, low price, good speed regulation.
Method of use: the best stable in horizontal plane, installed on the dc motor output shaft parts, cannot use a hammer to knock, knock prone to press into the dc motor drive, may cause damage to internal components, and cannot be used in the case of blocked.
Operating temperature range:
DC motor should be used at a temperature of -10~60℃.
The figures stated in the catalog specifications are based on use at ordinary room temperature catalog specifications re based on use at ordinary room temperature (approximately20~25℃.
If a geared motor is used outside the prescribed temperature range,the grease on the gearhead area will become unable to function normally and the motor will become unable to start.Depending on the temperature conditions ,it may be possible to deal with them by changing the grease of the motor's parts.Please feel free to consult with us about this.
Storage temperature range:
DC motor should be stored ta a temperature of -15~65℃.
In case of storage outside this range,the grease on the gearhead area will become unable to function normally and the motor will become unable to start.
Service life:
The longevity of DC motor is greatly affected by the load conditions , the mode of operation,the environment of use ,etc.Therefore,it is necessary to check the conditions under which the product will actually be used .The following conditions will have a negative effect on longevity.Please consult with us should any of them apply.â—Use with a load that exceeds the rated torque
â—Frequent starting
â—Momentary reversals of turning direction
â—Impact loads
â—Long-term continuous operation
â—Forced turning using the output shaft
â—Use in which the permitted overhang load or the permitted thrust load is exceeded
â—A pulse drive ,e.g.,a short break,counter electromotive force,PWM control
â—Use of a voltage that is nonstandard as regards the rated voltage
â—Use outside the prescribed temperature or relative-humidity range,or in a special environment.
â—Please consult with us about these or any other conditions of use that may apply,so that we can be sure that you select the most appropriate model.
