A method and device for realizing a verification code are provided. In some embodiments, a character verification code is obtained and displayed when it is determined to perform identity verification. The character verification code has an incorrect character based on a priori knowledge. The user is prompted to input a correct character corresponding to the incorrect character in the character verification code. Verification information is received. It is determined that the verification is successful when the verification information corresponds to the correct character of the prior knowledge; otherwise, the verification failed.

Method and device for realizing verification code

An information processing method, a terminal and a computer storage medium are disclosed. Here, the information processing method includes that: information of a first image is pre-acquired, and a first encryption key is generated and stored; information of a second image is acquired; a first image characteristic and second image characteristic of the information of the second image are extracted, wherein the first image characteristic represents background information of the first image, and the second image characteristic represents foreground information of the first image; a third image characteristic is obtained on the basis of the first image characteristic and the second image characteristic, and the third image characteristic is determined as a second encryption key; and similarity matching is performed on the second encryption key and the pre-stored first encryption key to generate a matching result, and a second image is authenticated according to the matching result.

The present disclosure discloses a CAPTCHA image generation method and apparatus, and a server, relating to the field of computer technologies. According to the present disclosure, first noise points are generated on a CAPTCHA code in some regions of an initial image and second noise points are generated on a background of the image in another region, so that a machine cannot filter out the noise points in a CAPTCHA image by means of some simple algorithms, increasing difficulty in recognizing the CAPTCHA code by the machine, reducing a risk that the CAPTCHA code is cracked by the machine, and having a strong crack-proof capability.

Captcha image generation method and apparatus, and server

A film application apparatus includes a first base configured to couple a film material and a second base rotatably coupled to the first base. The first base defines an opening and two through holes on opposite side of the first base, the through holes communicate with the opening. The second base defines a receiving chamber and the receiving chamber is configured for accommodating a work piece. The film application apparatus further includes a pressing component inserted through the first base, the pressing component penetrating through the opening from the two through holes for pressing the film material against to a face of the work piece.
