Two-dimensional code information security problem response measures

Using the cryptography principle, the combination of encryption technology and two-dimensional code coding technology, to achieve two-dimensional code information encryption and transmission. The image data is encrypted when the image is generated and decrypted in the process of image processing. However, it should be noted that the structure of the two-dimensional code image itself cannot be damaged due to encryption.

The two-dimensional code can be made into a complex color and distinctive pattern, so that users can more easily identify whether these two-dimensional codes come from the formal way when scanning. At the same time, the color of complex, with the distinctive characteristics of enterprises or businesses of the two-dimensional code, so that criminals in the modification and replacement of two-dimensional code more difficult, the cost is higher.

Never mind scanning a QR code, according to a US study, the biggest thing that drives users to scan a QR code is curiosity. All over the streets of the two-dimensional code content is still in the unsupervised stage, so users try to choose formal institutions, businesses, websites, media two-dimensional code information. For unknown origin of the two-dimensional code, must be vigilant, verify after scanning. In particular, there is a tempting two-dimensional code, such as winning prizes or coupons, to control their curiosity, to avoid the infection of the Trojan, malicious phone charges, or cause personal accounts and other private information leakage. Users in maintaining a good habit of scanning code at the same time, but also should continue to improve the two-dimensional code security awareness, through the scan code link website to fill in personal sensitive information, or conduct e-commerce and other activities, must pay attention to the domain name of the website, to ensure that it is a safe and formal website, do not be confused by the similar domain name, so as to walk into the trap of phishing websites.

With the wide application of two-dimensional code, network security situation is also facing more severe challenges, the use of two-dimensional code phishing is closely following the pace of technological development more and more diversified.
