The invention discloses a method and device for generating a picture identification code. The device comprises an identification code generator which is suitable for generating picture identification codes with a jamming intensity level according to the inputted jamming intensity level, wherein the number of picture identification codes is preset. The device also comprises an identification code recognizer which is suitable for recognizing the picture identification codes; a recognition rate calculating unit which is used for calculating the recognition correct rate of the picture identification codes; a setting unit which is suitable for outputting the preset jamming intensity level to the identification code recognizer, and setting the current preset jamming intensity level as a valid jamming intensity level when the recognition correct rate calculated by the recognition rate calculating unit is less than a preset threshold value, so as to enable the identification code generator to generate the picture identification codes with the jamming intensity level, wherein the picture identification codes are supplied to a client. The method and device reduce the probability that the picture identification codes are cracked by identification code software under the condition of guaranteeing that the method and device can be conveniently used by a user.
Description
technical field [0001] The invention relates to the technical field of the Internet, in particular to a method and device for generating a picture verification code. Background technique [0002] With the rapid development of the Internet, while the Internet provides people with rich resources, the security problems of the Internet are also becoming more and more prominent, and the verification code technology emerges as the times require. Captcha is designed to prevent malicious automation of websites by malware by exploiting the inimitability of the human brain. But a relatively simple picture verification code can be easily cracked by verification code recognition software. For experienced hackers, the simple picture verification code technology is useless except to increase the traffic of the website. Therefore, only by designing a more complex picture verification code that is not easy to be cracked can the security of the website be truly and effectively guaranteed. ...
