A method, device and system for verifying through verification code pictures

Abstract

The invention discloses a method for carrying out verification through a verification code image. The method comprises the following steps: according to a request sent by a user terminal, acquiring a first verification code image, wherein the first verification code image is an image with marked saliency regions; sending the first verification code image and input prompt information into the user terminal, wherein the input prompt information is used for instructing a user to select a region with the highest saliency from the first verification code image; according to saliency selecting information of the first verification code image sent by the user terminal and the saliency regions, calculating confidence degrees, wherein the confidence degrees are used for indicating the degree to which a subject inputting the saliency selecting information to the user terminal is a real user; according to the confidence degrees, determining whether the subject inputting the saliency selecting information to the user terminal passes the verification. According to the scheme provided by the embodiment of the invention, whether the subject carrying out the verification through a verification code is the real user or a machine can be determined through the salience of the image; the machine cannot recognize the saliency of the image, so that the security of the verification code can be improved.

Description

technical field [0001] The present invention relates to the technical field of verification codes, in particular to a method, device and system for verification through verification code pictures. Background technique [0002] Hackers have an artifact called "automaton" for cracking passwords. By exhaustively enumerating passwords, they will automatically try to crack other people's passwords one by one. With the verification code, since the automatic machine cannot understand the letters in the picture like a human, it can only be stuck there and cannot try in batches. Therefore, the chance of the password being cracked is greatly reduced. Practice has proved that verification codes can greatly reduce common network security risks such as malicious brute force cracking of passwords, swiping tickets, flooding forums, and swiping pages. It is currently a common security defense method for many large websites. [0003] Captchas are currently effective public automated procedu...
